Staying one chapter ahead of the class, or, reputable science from a source of questionable reputability</description><title>As I Learn It</title><generator>Tumblr (3.0; @asilearnit)</generator><link>http://asilearnit.tumblr.com/</link><item><title>Honeybees: Nature`s Little Communists, Part 4.</title><description>&lt;p&gt;&lt;em&gt;&lt;span&gt;So without too much introduction, let’s continue on from my last post. The only thing that I’d really like to preface with is this: Much of the answer to &lt;/span&gt;&lt;/em&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;how &lt;/span&gt;&lt;em&gt;&lt;span&gt;honeybees form into a single ‘superorganism’ can be uncovered in discussing &lt;/span&gt;&lt;/em&gt;&lt;span&gt;why &lt;/span&gt;&lt;em&gt;&lt;span&gt;exactly honeybees need to do this. So to begin simply, let’s discuss&amp;#8230;&lt;/span&gt;&lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;strong&gt;&lt;span&gt;The Purpose of Life&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/strong&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;For human beings, the purpose of any given person’s life is variable on so many different levels. Beyond even the obvious &lt;/span&gt;&lt;em&gt;&lt;span&gt;eat, sex, die&lt;/span&gt;&lt;/em&gt;&lt;span&gt; trifecta, there is an enormous range of motivations people have for their lives. Some people live for art, some kill for wealth, others die fighting for Black Friday specials. Who am I to judge?&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Now let’s contrast this with the honeybee’s life, which is infinitely more straightforward. Boiled down, a honeybee devotes the vast majority of its existence in supporting its colony’s two most vital endeavors. These are: &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;div&gt;&lt;span&gt;1. Staying warm during the cold season.&lt;/span&gt;&lt;/div&gt;

&lt;div&gt;&lt;span&gt;2. Creating and storing a lot of food during the warm season.&lt;/span&gt;&lt;/div&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Really, this is it. So why is heat (and through it, honey) so important to bees? Well, if we can ignore for the moment disease and/or any creature that willfully wishes to do harm to bees (chiefly bears or kids with BB guns), a honeybee colony’s chief adversary is cold weather. &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;strong&gt;&lt;span&gt;Friction Heat and Honey, Where Food Fetishists Totally Got It Right&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/strong&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Winter is a very difficult time for insects. Because they are ectothermic, meaning they lack the ability to create heat internally, during the winter months insects usually do one of two things: hide, or die. There aren’t many options here. A lot of evolutionary progress insects have made toward surviving the winter has been in the ‘hide’ category. Faced with the biting cold, bugs will burrow into trees, huddle together under rocks, bury in the earth, or find other places to hole up (sometimes literally) and go dormant. Some can survive freezing temperatures and just wait to warm up in spring. Others need to keep their body temperature above a certain level. A few even migrate*. Surprisingly (or maybe not, given their spineless nature) most insects have actually adapted to the ‘dying’ strategy. They lay their eggs in a relatively temperate area, hope their progeny will make it into next year, and die. (These are nature’s quitters.)&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Now honeybees have a very unique overwintering strategy in that they don’t do &lt;/span&gt;&lt;em&gt;&lt;span&gt;any &lt;/span&gt;&lt;/em&gt;&lt;span&gt;of the things I’ve listed above. Though the colony itself appears to go dormant during the winter months (no bees leave), the individual honeybees themselves are still very much active within their hive throughout the entire year. They are, in fact, one of the very few cold-climate insects that maintain year-round activity. So what exactly are they doing all winter long? In a word: shivering.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&amp;#8230;But actually. Though an individual bee isn’t able to regulate its own internal temperature, collectively the honeybee colony can use what entomologists have termed ‘the buddy-system’ to keep one another warm. When a honeybee senses that the hive is a bit too cold for its taste (each bee has a unique tolerance, which causes a kind of cold-response bell curve), it’ll make its way to the brood, latch onto the comb, and repeatedly flex its flight muscles (read:shiver) until it has created enough friction heat to warm up the surrounding comb about one smidgen (technical term). This shiver response, when adopted &lt;em&gt;en masse&lt;/em&gt;, ensures not only that the honeybee’s individual temperature never dips low enough to kill it, but also keeps the brood’s temperature between thirty-three to thirty-six degrees centigrade (which is important, but I’ll get to this later).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;But here is the catch. Though this mass shivering effort is remarkably effective, it&amp;#8217;s also incredibly energy-costly: The shivering bees need a&lt;/span&gt;&lt;span&gt; &lt;/span&gt;&lt;u&gt;constant&lt;/u&gt;&lt;span&gt; influx of honey to keep their efforts going. So here we can see, going back to my introduction to this post, why it is exactly that honeybees need to act collectively as a ‘superorganism’. If a honeybee colony was made up of merely a few thousand self-guided individual units searching blindly for flowers all summer, not a single hive would be able to collect enough food to make it through the winter. Even &lt;em&gt;with &lt;/em&gt;&lt;/span&gt;&lt;span&gt;their combined and directed effort about ⅓ of all honeybee colonies will, depending on the length and severity of the winter, run out of food before spring shows, and so starve, freeze, then die. &lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;So honeybees need some sort of mechanism to not only direct their collection of food, but to make the effort as efficient as possible as well. They are working against the ever-ticking seasonal clock, and if they fail, they die. (Think &lt;/span&gt;&lt;em&gt;&lt;span&gt;Speed&lt;/span&gt;&lt;/em&gt;&lt;span&gt;, with Keaunu Reeves. Except with more lives at stake.) And so, faced with the prospect of a very real, ever looming specter of death, what do these bees do?&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Well, as it turns out, mostly dance.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;*&lt;/span&gt;&lt;span&gt;Danaus plexippus&lt;/span&gt;&lt;span&gt; to the Northern American southwest (Monarch Butterflies), and &lt;/span&gt;&lt;span&gt;Oldus americanus&lt;/span&gt;&lt;span&gt; to Florida.&lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/30174692849</link><guid>http://asilearnit.tumblr.com/post/30174692849</guid><pubDate>Sat, 25 Aug 2012 11:46:49 -0400</pubDate></item><item><title>Honeybees: Nature`s Little Communists, Part 3.</title><description>&lt;p&gt;&lt;span id="internal-source-marker_0.30135722286352895"&gt;&lt;em&gt;Alright, up to this point I’ve tried to focus on the honeybee as a singular organism, ignoring for the moment what is doubtlessly its most interesting feature: the creatures’ social organization and interactions.&lt;/em&gt;&lt;/span&gt;&lt;em&gt; So lets get to the good part now, let’s talk about the&lt;strong&gt; colony&lt;/strong&gt;. &lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;u&gt;The Human Organism and the Honeybee Superorganism&lt;/u&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;One of the most fascinating things about the human body is that we commonly refer to it as a single entity. Actually, better yet, is the fact that we do this despite any and all evidence to the contrary. Though it is fairly common knowledge that really, we are all completely composed of trillions of individual cells (&lt;/span&gt;&lt;em&gt;each no more or less ‘alive’ than the entire body&lt;/em&gt;&lt;span&gt;), we still manage to go by first and last names. &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Maybe because it is the only way we can make our own lives make sense (and also because it is extremely hard to convict a hand, on its own, for theft), but there is usually not much of an argument that somehow, we are each more than the sum of our individual parts. More than just the collective effort of countless, tiny, but distinguishable lifeforms. I am not just separate cells, I am William, a whole entity.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;But even though this is hardly ever debated, it is extremely hard to answer &lt;/span&gt;&lt;em&gt;how &lt;/em&gt;&lt;span&gt;it proves true. How am I more than my clearly living pieces? Usually we just reconcile this oversight by just not thinking about it, but, if we are pushed for an answer, we may discuss the ‘mind’ or some quality of self-awareness. If we’re really stuck, we’ll use the word &lt;/span&gt;&lt;em&gt;soul &lt;/em&gt;&lt;span&gt;and move the discussion into the realm of theology or philosophy. But in expressing our singular identity, the ‘mind’ arguments don’t explain the various parts of our bodies we very much rely on, but are in many ways completely autonomous and beyond our control (immune system, circulatory system, masturbatory system). And because I am trying to steer clear of any discussion of theology, I will ignore in my questioning the concept of the soul.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Now before I am accused of otherwise, I am not trying to convince you that you, who are currently reading and internalizing this sentence, don’t exist as a ‘person’. I only want to express the fact that there is a bit of a grey area when it comes to the discussion of humans (and all other multi-cellular organisms) as more than the units that they are made up of. &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So fine, but why am I bringing this up? Because, and here is where we get back to bees: When we look at Honeybee colonies, we are faced with a similar problem. Yes, we can easily break down the colony into a couple thousand independent bees, but like the problem with breaking me down into cells, we still can not rid ourselves of the fact that their group effort somehow creates an entirely new organism, fully functional and markedly directed. This greater honeybee colony organism though, is what we call a ‘&lt;/span&gt;&lt;strong&gt;superorganism&lt;/strong&gt;&lt;span&gt;’, due to the fact that is built up by other multi-cellular organisms (as opposed just single cells), and also because it is a concept widely described within the scientific community as ‘super’.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And when you look carefully, comparing the nature of honeybee colonies and human bodies is actually not all that difficult. In so many ways the honeybee superorganism shares a great deal in common with multi-cellular organisms like humans: The colony has a centralized ‘body’ of a comb, in which it keeps, in constant homeostasis: its temperature (at a creepily near-human thirty-three to thirty-six degrees centigrade), its influx of food and water, and its outflow of waste (that’s pooping, if you didn’t get that). It has mechanisms to defend itself, both from physical attack and infection. It has a relatively low and mammal-like rate of reproduction (how often it breeds new colonies, not bees). But most importantly, the colony is smart: It can, without the understanding of any single bee, properly delegate its workforce efficiently and effectively to manage &lt;em&gt;all of these things simultaneously &lt;/em&gt;without over or under-expending its resources. Yes, dumb little bees do this.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So how? &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Great question.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/9966808610</link><guid>http://asilearnit.tumblr.com/post/9966808610</guid><pubDate>Sat, 10 Sep 2011 12:28:00 -0400</pubDate></item><item><title>Hello! Thanks for an interesting read so-far about bees. I have always loved bees, and finding a paper that can put something in layman terms is always nice.&lt;br /&gt;&#13;
&lt;br /&gt;&#13;
Anyways, I had a question regarding your second part, and their mating in particular. How can this mating method produce enough variation for natural selection? Do the queens in some way choose what drones to mate with? &lt;br /&gt;&#13;
&lt;br /&gt;&#13;
Its just that understanding how natural selection works with, say, deer, is clear enough. But what with bees?</title><description>&lt;p&gt;&lt;span id="internal-source-marker_0.991281975304324"&gt;OK,  this is a fantastic question. It is also though, jumping the gun a  little bit. So please bear with me, as much of this answer might only  touch on a couple of topics I‘ll get to and clarify in my next few  posts:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Darwin  himself confessed utter bafflement in regards to how honeybee colonies  fit into his then-unpolished theory of evolution. He may have been  quoted saying, “I am baffled, utterly,” or I might have just made that  up. Regardless, to Darwin it seemed that he had an entire group of  creatures, &lt;/span&gt;&lt;em&gt;&lt;span&gt;many of which were completely sterile&lt;/span&gt;&lt;/em&gt;&lt;span&gt;,  that were not only not competing with one another, but were in fact  living harmoniously and in many ways altruistically together! Confused  and a bit hurt, Darwin may or may not have sat back in his chair and  imagined burning down every last beehive he could find.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Naturally,  questions arose (one of which you voiced). How can these sterile  workers pass on their genes without breeding? Why weren’t they competing  with one another? How could they produce fertile offspring (new queens)  at such an absurdly low rate? How is there even enough genetic  variation in this tactic? “This… this doesn’t make any sense at all,”  Darwin may have also not been quoted on saying, while possibly not  clearing his entire desk with one angry swipe of his arm. “You fucking  bees, you’re ruining my precious theory. &lt;/span&gt;&lt;em&gt;&lt;span&gt;I’ll kill you&lt;/span&gt;&lt;span&gt; all if I have to!&lt;/span&gt;&lt;/em&gt;&lt;span&gt;”  OK, that he definitely didn’t say, but even still, the point stands. It  seemed that the honeybee colony’s existence ran completely contrary to  natural selection as it was understood.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The  core of the answer to this mystery is essentially the topic of my next  post, so excuse me for being brief. The thing is, honeybees only really  fit into the process of natural selection on the scale of the &lt;/span&gt;&lt;span&gt;colony&lt;/span&gt;&lt;span&gt; (as a single entity composed of bees), not necessarily as the  individual bees themselves. A colony, because it has divided the labor  of its survival (and reproduction) amongst its members, is completely  dependent on the individual members survival in turn. (An all for one,  one for all type of deal.) The risk of competition within a hive is so  great and the results so weakening, that any sort of competition would  be sure to lead to the complete death of the whole colony*, and thereby  the death of the inciting competitors as well. In short: Bees that fight  with one another kill everyone and through that, kill themselves and  fail to pass on their fightin’ genes. So that solves the mystery of the  peaceful lack of competition, but how is this altruistic behavior passed  on to the next generation if the workers are all sterile?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Again, the answer to this question must be viewed on the scale of the&lt;/span&gt;&lt;em&gt;&lt;span&gt;&lt;/span&gt;&lt;/em&gt;&lt;span&gt;&lt;em&gt; colony&lt;/em&gt;,  not the individual bees. While worker bees have varying levels of  relation between themselves (depending on whether or not they share a  father), they are all related to their mother/queen by 50%. Because of  this, the colony has a definite &lt;/span&gt;&lt;span&gt;shared &lt;/span&gt;&lt;span&gt;gene-pool, which it is then trying to pass on to the next generation (through the queen). So sterile worker bees pass on their &lt;/span&gt;&lt;em&gt;shared genetic material&lt;/em&gt;&lt;span&gt; (that they have in common with their queen) to the next generation when their queen creates a new colony for them.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Even  though only a fraction of the worker’s genes are sure to make it to  that next generation, it is enough to continually propagate this  beneficial sterilility and altruistic behavior. This is called kin  selection, a process of helping the reproductive success of ones close  relatives (who share genes), and honeybees are adamant about sticking to  it.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So  finally, we come to your question (I will leave the question I didn’t  answer for later posts). How is there enough variation within a hive and  its gene-pool? Sadly, because of the extreme difficulty of observing  the queen’s only mating flight, there is very little known beyond the  basics about the actual mating process. What we do know though, is that  the queen mates with &lt;/span&gt;&lt;em&gt;&lt;span&gt;eight to ten&lt;/span&gt;&lt;/em&gt;&lt;span&gt; different dudes. That, in itself, is more than enough variation for a  range of dynamic and varied progeny. Additionally, and this will be  extremely important in my later posts: &lt;/span&gt;&lt;em&gt;&lt;span&gt;Based &lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;on the temperature which they are raised&lt;/span&gt;&lt;/em&gt;&lt;span&gt;,  genetically similar honeybees express differences in ‘personality’ (how  or when they respond to different stimuli). This induces a second level  of variation, although not genetic, within the hive.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;I hope I answered your question.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;*At  the very least, it would weaken the colony’s ability to function  cohesively, and so over time such a trait would be eliminated. &lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/6026729169</link><guid>http://asilearnit.tumblr.com/post/6026729169</guid><pubDate>Mon, 30 May 2011 23:49:00 -0400</pubDate></item><item><title>Honeybees: Nature`s Little Communists, Part 2. </title><description>&lt;p&gt;&lt;em&gt;&lt;span id="internal-source-marker_0.022002129248164692"&gt;After  a couple of rewrites, I think I’ve found that the most logical way to  structure this is to first overview the very basics of an individual  honeybee’s biology. I’ll hold off until my next post to zoom a bit out  in scope, and do a relatively similar analysis with the entire colony.  Even though what I really want to talk about is how honeybees work  together, I’ve found that without a really concise examination of the  pieces, it’s hard to appreciate the entire puzzle.&lt;/span&gt;&lt;/em&gt;&lt;br/&gt;&lt;br/&gt;&lt;em&gt;(Also,  important side note: I’m going to limit my analysis to a single species  of honeybee, Apis mellifera, as it is the most common bee used in  beekeeping, as well as the most widely disseminated. It is native to the  whole of Africa, Europe, the Middle East, and was introduced to both  the Americas in the 1600’s.)&lt;/em&gt;&lt;br/&gt;&lt;span&gt; &lt;/span&gt;&lt;br/&gt;&lt;span&gt;Alright,  let’s ignore for a moment the social aspect of honeybees, and talk  about the honeybee as a single creature. I think this is important  because before we can discuss (and really even appreciate) the colony as  a whole, there is a whole lot to understand about the &lt;/span&gt;&lt;strong&gt;anatomy&lt;/strong&gt;&lt;span&gt;, &lt;/span&gt;&lt;strong&gt;castes&lt;/strong&gt;&lt;span&gt;, and &lt;/span&gt;&lt;strong&gt;jobs&lt;/strong&gt;&lt;span&gt; that are unique to honeybees as a species.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;u&gt;Anatomy: Baby Got Thorax&lt;/u&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;em&gt;I’ll be basing this off of the diagram that Irene at &lt;a href="http://quatremilliards.tumblr.com/" target="_blank"&gt;&lt;a href="http://quatremilliards.tumblr.com/" target="_blank"&gt;http://quatremilliards.tumblr.com/&lt;/a&gt;&lt;/a&gt; drew for me. It’s of a female ‘worker’ bee, (I’ll go over the different  types of bees later, but the colony consists almost entirely of worker  bees who are in charge of all the non-reproductive tasks of the hive)  and it’s probably best to keep referencing the diagram. &lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;For  centuries biologists have marveled at the peculiar ability of honeybees  to ‘get a lot of different shit done really goddamn fast’. And while  this may not exactly be how they would have phrased their admiration,  there is really no doubt that the individual bee is a seriously  industrious motherfucker. It is no surprise then that its anatomy  reflects this fact. Highly tweaked and tuned, a honeybee has many unique  physical features that allow it to specialize in any one of dozens of  different tasks it may be required to undertake. I’ll sub-categorize  these features, but note that this is by no means a complete list, just  what I think is relevant.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;&lt;span&gt;&lt;/span&gt;&lt;strong&gt;Foraging Features&lt;/strong&gt;&lt;span&gt;:  Honeybees are fairly well adapted at carrying their food and water long  distances back to their hive. Their stomachs are sectioned off into a &lt;/span&gt;&lt;em&gt;crop &lt;/em&gt;&lt;span&gt;(where they store water or nectar for travel, like a horribly creepy pocket) and a &lt;/span&gt;&lt;em&gt;midgut&lt;/em&gt;&lt;span&gt;,  where the actual digestion starts. Honeybees have control over whether  or not what they swallow makes it past the crop, and are also able to  regurgitate the food stored in their crop on a whim, which makes a  fascinating party trick I have yet to master. For carrying pollen they  use a different tactic: They wet down the pollen with their saliva, and  pack it firmly onto the hairs on their rear legs, where it is securely  clustered in a ball.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Heating Features&lt;/strong&gt;&lt;span&gt;:  Honeybees are remarkably good at creating heat, which is actually an  exceptionally important aspect of their biology. What they do is  isometrically flex (read: shiver) their &lt;/span&gt;&lt;em&gt;wing muscles&lt;/em&gt;&lt;span&gt; really rapidly, which produces a surprising amount of heat. This both  warms them to a point where they are able to fly (bees can’t fly if they  are internally cooler than 35 degrees Centigrade) and is also used to  raise the temperature of the hive (the hive needs to maintain a very  specific internal temperature for a bunch of reasons I’ll get on that  later).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Communicative Features&lt;/strong&gt;&lt;span&gt;: Honeybees have a special gland called the &lt;/span&gt;&lt;em&gt;Nasanov’s gland&lt;/em&gt;&lt;span&gt; that produces a strong and strangely citrus-scented pheromone (think  ‘lemon pledge’ meets farting). This pheromone helps lead other bees to  scentless areas (such as bodies of water), and marks the entrance of the  hive so amature foragers can find their way back home. &lt;/span&gt;&lt;em&gt;Side  note: Some of the most important communication done by honeybees is  mainly behavioral and not very easily ascertained by focusing on their  anatomy. I’ll spend a large time focusing on this in my next blog, but  bees mostly communicate through seemingly innocuous interactions and, I  kid you not, interpretive dance. Yes, you read that correctly.&lt;/em&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Hive Building Features&lt;/strong&gt;&lt;span&gt;:  Fun fact: All insects coat their exoskeleton with a thin layer of wax  to keep them from drying out. It’s this reason why bugs look so shiny,  and perhaps also why they taste so horrible. Honeybees have adapted this  wax-making ability with their &lt;/span&gt;&lt;em&gt;wax glands&lt;/em&gt;&lt;span&gt;,  to produce excess wax when they need it. They chew, heat, and mold this  wax to create their comb and hive, though they mix it with a tree resin  they collect called &lt;/span&gt;&lt;span&gt;propolis &lt;/span&gt;&lt;span&gt;(which has both anti-fungal properties and adds structural stability to the comb).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Feeding Features&lt;/strong&gt;&lt;span&gt;:  Bees eat three types of food: Honey (which is a mixture of nectar and  their saliva), pollen, and a substance known as ‘royal jelly’. Royal  jelly is a very protein- and hormone-rich secretion produced in the &lt;/span&gt;&lt;em&gt;hypopharyngeal gland&lt;/em&gt;&lt;span&gt;,  which is located in the honeybee’s head. So yeah, bees occasionally eat  one another’s head juices, although in highly regulated amounts. This  stuff is also very important to the bee’s caste system, because eating  large amounts of royal jelly in the larval and pupal stage of a bee’s  development will turn a normal worker bee into a fabulous queen bee.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Hurty-Stingy Features&lt;/strong&gt;&lt;span&gt;: Sterile worker bees have adapted ovipositors (egg laying organs) called &lt;/span&gt;&lt;em&gt;stings&lt;/em&gt;&lt;span&gt; with which they use to attack their enemies (bears, competing hives,  rodents, the 13-year-old me that for god knows what reason thought it  was a good idea to throw his &lt;/span&gt;&lt;em&gt;shoes &lt;/em&gt;&lt;span&gt;at a bee hive). This sting is coated with venom from its &lt;/span&gt;&lt;em&gt;venom sac&lt;/em&gt;&lt;span&gt;, and if you ask the thoroughly retarded 13-year-old me, that stuff hurts.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;u&gt;The Caste System: Workers, Drones, and fabulous, fabulous Queens&lt;/u&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Gender, one of the cruxes of the honeybee caste system, means something completely different for bees than it does for humans. &lt;/span&gt;&lt;em&gt;All &lt;/em&gt;&lt;span&gt;fertilized  eggs produce genetically female bees. These bees, depending on how they  are fed during their larval and pupal stage, will then either go on to  become sterile worker bees, or far less commonly, queen bees. It is  unfertilized eggs (which therefore share 100% of their genetic material  with their mother) that become male, or drone, honeybees. Let’s do a  fairly brief overview of this.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;&lt;strong&gt;Drone bees&lt;/strong&gt;&lt;span&gt;:  Queen bees can decide, although only during the warm summer months  (mating season), to lay a very small percent of their eggs unfertilized.  These unfertilized eggs hatch into horndog male drone bees, whose sole  focus is on finding and having sex with un-mated virgin queens from  other hives. If they’re lucky, and often they aren’t, they’ll have sex  once and then immediately die. They do this and&amp;#8230; actually that’s it,  it’s all they do. They literally serve no other purpose than to fly  around hunting for tail. And, in the ultimate bachelor move, they do not  even feed themselves. This is actually kind of funny, because when the  rest of the colony decides the drones have served their purpose, the  colony will simply stop feeding them, and they all die. Ha?&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Queen bees&lt;/strong&gt;&lt;span&gt;:  If the old queen dies (or is rendered ‘unfit’), or if the colony is  sufficiently large, it will decide as a whole to rear new queen bees.  This happens very infrequently, only every one to three years if the old  queen is still alive, or immediately if she dies. How the colony rears  new queens is by feeding a few (usually three to five) of the newborn  female bees a very large amount of royal jelly (the face juice we talked  about). Because of the high hormone content of this diet, the pupa and  larvae of these soon-to-be queen bees will develop much differently than  the otherwise normal worker bees. If the old queen was still alive when  the colony started to produce new queens, she will fly off (before the  new queens hatch) with two-thirds of the workers and start a new hive.  Normally, the first of the queen bees to hatch will attempt to kill off  the others and claim the hive for her own, but in cases where the colony  is really, really large, she’ll do the same as the old queen and take  another fraction of the workers to leave and found another new colony.  The next queen to hatch then kills all the others queens and claims the  hive for her own. After this whole escapade, the new queen will leave on  her only mating flight, where she does it with &lt;/span&gt;&lt;em&gt;eight to ten &lt;/em&gt;&lt;span&gt;dudes  from other colonies. When she comes back, she’s loaded with enough  semen for her entire life. And, for the rest of her life, that’s all she  does, use this semen to pump out thousands of babies. &lt;/span&gt;&lt;em&gt;Side  note: The queen, despite her regal name, has absolutely no level of  control over the other bees, and is merely pushed around all day as she  lays eggs. If, in fact, she at any time becomes injured or is deemed  unfit to continue having children, the other bees will simply ignore her  completely, and she will die of starvation as she watches the hive  breed her replacement. Pretty cold, huh?&lt;/em&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Worker Bees&lt;/strong&gt;&lt;span&gt;:  These are the backbone of the entire bee economy and workforce. Because  they are in charge of and do everything non-reproductive in the hive,  they’re pretty much what I’ll be talking about for the entire rest of my  blog. Because of this, I’ll move straight into the different jobs a  honeybee has during its lifetime, because I’m essentially only  referencing the worker bees.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;u&gt;Various Jobs: Odd, Hand, and Others&lt;/u&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So,  to finish up this blog, let me do a very brief overview of the  different areas where a colony has to allocate its workforce. &lt;/span&gt;&lt;em&gt;I’d  to take this moment to note that honeybees have an extremely strong  correlation between their age and their current vocation. For example,  usually only the oldest of the bees will engage in foraging, and usually  only the youngest will engage in taking care of the brood (larvae and pupae). This  though, is flexible, and in the case of a sudden and large extermination  of the workforce*, the colony will regulate itself back into proper  homeostasis.&lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So,  at any given point, a single honeybee may be engaged in one of these  various different activities. How these jobs are efficiently allocated  though, I will leave to explain in future posts. For now I just want to  give a feeling for the vast range of jobs a single bee may undertake.  Here is only a partial list of what a honeybee may be required to do:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;&lt;span&gt;Clean out the old cells of the honeycomb for new eggs or honey and pollen storage.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Take care of and feed the brood (larvae and pupae honeybees that are still confined in cells).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Tend and clean the queen bee.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Feed and groom fellow nest-mate bees.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Keep the brood area of the comb constantly between 33 and 36 degrees Celsius (cool &lt;/span&gt;&lt;em&gt;and &lt;/em&gt;&lt;span&gt;heat).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Build and shape more of the comb.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Forage for nectar, pollen, water, and tree sap (this is a huge one).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Inform other bees about nectar and pollen forage sites.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Patrol and guard the hive.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Store nectar and pollen in the comb.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Lay eggs (this one is for the queen only).&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Be fabulous (this one is for queens as well, but may extend beyond bees).&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And  this is only a partial list. Even still, it’s quite obvious that much  like a man reading dirty magazines at the office, these little honeybees  are definitely hard at work. But what this list doesn’t fully explain is  how precisely these jobs are allocated. Somehow the bees seem to never  extend more resources than are required, and maintain a constant balance  between deciding which workers should be doing each activity. The level  of efficiency in this allocation is absolutely mind-blowing, as is the  fact that it’s done completely &lt;/span&gt;&lt;em&gt;&lt;u&gt;without&lt;/u&gt;&lt;/em&gt;&lt;span&gt;&lt;em&gt; a centralized intelligence&lt;/em&gt;.&lt;/span&gt;&lt;span&gt; &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;If I’ve done my work, this should lead you to ask some questions, chiefly: Well how the hell do they do that? &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And that’s a damn good question.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;* See Tom Seeley’s book: &lt;/span&gt;&lt;em&gt;The Researcher’s Baseball Bat; How Bees Maintain A Balance Even In The Face of My Iron-Armed Adversity.&lt;/em&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/5795310335</link><guid>http://asilearnit.tumblr.com/post/5795310335</guid><pubDate>Tue, 24 May 2011 03:35:00 -0400</pubDate></item><item><title>I’d like to give an earnest and sincere thank you to Irene, a...</title><description>&lt;img src="http://25.media.tumblr.com/tumblr_llo6marxfI1qgrwsuo1_500.png"/&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;&lt;span id="internal-source-marker_0.6595622293070362"&gt;I’d like to give an earnest and sincere thank you to Irene, a fantastic artist and fellow science lover who runs a blog at &lt;/span&gt;&lt;a href="http://quatremilliards.tumblr.com/" target="_blank"&gt;&lt;span&gt;&lt;a href="http://quatremilliards.tumblr.com" target="_blank"&gt;http://quatremilliards.tumblr.com&lt;/a&gt;&lt;/span&gt;&lt;/a&gt;&lt;span&gt;.

Although, instead of continuing to discuss humans, I’d  like to take a step sideways on the evolutionary tree, and steal a quick  glance at one of our most complex neighbors. Perhaps also one of our  most important. And stingy. Definitely stingy. Yes, that’s right, I’m  talking &lt;/span&gt;&lt;em&gt;bees&lt;/em&gt;&lt;span&gt;, bitches. &lt;/span&gt;&lt;strong&gt;Honeybees&lt;/strong&gt;&lt;span&gt;.&lt;/span&gt;&lt;br/&gt;&lt;span&gt; &lt;/span&gt;&lt;br/&gt;&lt;span&gt;What  I’m about to cover in this blog is a decent overview of social  organization of a honeybee colony: How they manage to communicate,  organize, and allocate resources to essentially a countless amount of  different operations (all without any sort of leader) with a  mind-blowingly high level of economy and accuracy. As I discuss this,  I’ll also have to try to reconcile the fact that really, despite their  brilliant group behaviour, they are still simply a collection of  near-mindless idiots.* Not one of the bees has even the slightest idea  what it is achieving, and they also lack the abilities to both read  literature or poach an egg.&lt;/span&gt;&lt;br/&gt;&lt;span&gt; &lt;/span&gt;&lt;br/&gt;&lt;span&gt;So,  this is going to require a serious bit of back and fourth between  examining the actions of the single organism working on its own, and the  collective efforts of the colony. First though, I’m going to need to  quickly overview the life of a bee and it’s hive. I’d also like to  discuss for a bit the importance of the honeybee itself in our  ecosystem, how this possibly could have evolved, and finally, what we  can learn from this complex organizational system of autonomous units.  Oh, and why honey burns so bad when you put it in your eye.&lt;/span&gt;&lt;br/&gt;&lt;span&gt; &lt;/span&gt;&lt;br/&gt;&lt;span&gt;I’ll be taking my facts from three books I read on the subject, Tom Seeley’s &lt;/span&gt;&lt;span&gt;&lt;em&gt;The Wisdom of the Hive&lt;/em&gt;,&lt;/span&gt;&lt;span&gt; and &lt;/span&gt;&lt;em&gt;Honeybee Democracy&lt;/em&gt;&lt;span&gt;, and a translation of Jürgen Tautz’s &lt;/span&gt;&lt;span&gt;‘&lt;em&gt;Honeybee Phenomenon&lt;/em&gt;’. &lt;/span&gt;&lt;span&gt;Fantastic  books, I highly recommend the second one by Seeley, he’s a great  writer, loves his research, and it comes through in the book. So let’s  get started, shall we?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;u&gt;How Nature Gets Its Game On&lt;/u&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;I  think in this first part in my blog on honeybees, I’ll just start with  some evolutionary history. I’ll work on a primer/overview of the bee’s  anatomy and physiology in my next blog.&lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The  modern honeybee’s life is so unextractably interconnected with the  flowers it resides around, that to fail to include them in a description  of the bee’s evolution would be remiss. It is no coincidence that we  find the first evidence of primitive bees about 100 million years ago,  roughly the middle of the Cretaceous period, when flowering plants  (angiosperms) started to become widespread and replace cone-bearing  trees (conifers) as the dominant flora on earth. Actually, the rise of  angiosperms is really an interesting tale, as these plants managed to  biologically and physically mold the face of the earth very rapidly, but  not without a bit of help:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The forebears of flowering plants, &lt;/span&gt;&lt;em&gt;gymnosperms &lt;/em&gt;&lt;span&gt;(such  as the majestic redwood), had an incredibly difficult time having sex  with one another. Since both partners were hopelessly immobile, (unlike  in humans, where only one person is completely motionless) they relied  on producing an incredibly costly amount of pollen and tossing it into  the air, just hoping that some of it would be carried by the wind and  impregnate someone somewhere. And though often it would, the process  took &lt;/span&gt;&lt;em&gt;a lot&lt;/em&gt;&lt;span&gt; of energy and co-operation. And an unbelievable amount of pollen. Ever get allergies? That’s from this effort.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So,  a long time passed, but slowly a second method was devised. The flora  got together to discuss the matter, and after much deliberation and  evolution, finally decided that instead of ejaculating wildly into the  air all spring, why couldn’t they just hire some animals to do their  fucking for them?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Insects,  birds, and all other manner of animals interested in this new,  profitable type of sex-trade were delegated for this new type of  pollination, with the promise that: As long as stamens would be rubbed,  and anthers gently fondled, these animals would be fed like kings. The  plants devised incredibly sweet substance for this purpose (nectar), and  even allowed some of the pollen or even bits of the flower to be eaten  as payment (read: gentle masochism).&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And  this method, though odd, delicate, and reliant on a third-parties  cooperation, was found to be both radically effective, and  evolutionarily titillating. Suddenly, seemingly everyone was doing it.  Animals became very competitive over this new source of food and energy,  and slowly these flower plants were allowed to become fickle, even  choosey over who they let ‘tap that’ nectar. Over time, one such animal  started to prove its worth in this regard. Taking only pollen and the  sweet nectar made for this purpose, this animal promised to harm no  flower and pollinate a very high amount of a single species (as trying  to pollinate two different species of flowers yields nothing) very  rapidly. Many of flowers liked this very much, and soon they too were  competing, this time amongst one another for the affections of this  mysteriously effective lover. They changed shape, started wearing  intense perfumes, even painted their faces a bit.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;This animal is the honeybee, and it is a total &lt;/span&gt;&lt;span&gt;&lt;em&gt;playa’&lt;/em&gt;.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;*Any child with a mason jar knows that the individual bee is easily foiled, and almost as dumb an animal as the child itself.&lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/5492057264</link><guid>http://asilearnit.tumblr.com/post/5492057264</guid><pubDate>Sat, 14 May 2011 17:30:00 -0400</pubDate></item><item><title>Our Sexy Senses, Part 4.</title><description>&lt;p&gt;&lt;span id="internal-source-marker_0.17054576460129056"&gt;So last I left off, I expressed this single completely absurd, but totally factual claim:&lt;/span&gt;&lt;em&gt; That  our visual perception is an interpretation of a reality far different  than we naturally perceive. In actuality, the universe around us is void  of both color and any &amp;#8216;solid&amp;#8217; appearance we associate with it. Neither  of those qualities exist outside our own minds.&lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And again, we know this to be true because:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;&lt;span&gt;Color is an mental interpretation of an arbitrary section of electromagnetic radiation, and&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;The vast, vast majority of our everyday universe consists of empty  space barely freckled with tiny bits of matter. We don&amp;#8217;t actively  register this because what we &amp;#8216;see&amp;#8217; is the energy being radiated off of  that matter.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;&lt;em&gt;(Side  note: I could try to make an even bolder claim at this point, and start  on how our perception of reality as innately &amp;#8216;three dimensional&amp;#8217; can be  called into question as well. But really, I think that would be totally  superfluous right now. All I want to do is to plant the seed of doubt  that reality as we see it may not be accurate to how it &amp;#8216;really&amp;#8217; is.)&lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So  at this point, if you have any shred of sense in you, you&amp;#8217;re going to  want to start to kick and buck at this idea. I mean, how can you not?  This sounds completely crazy. Everything around you is barely a pinch of  physical matter? The reality is that our lives are almost entirely  empty space?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;How can that be? Even if vision is in question, we still &lt;/span&gt;&lt;em&gt;feel&lt;/em&gt;&lt;span&gt; that things are whole. If the objects around me aren&amp;#8217;t really as  &amp;#8216;solid&amp;#8217; as I see them, why can I still pick them up? How do I touch  them?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Great questions, me. The short answer: Magic. The long answer:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;u&gt;Touch&lt;/u&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Anyone who has ever spent a day at the zoo can claim that they have experienced the seemingly awe-inspiring power of physical &lt;/span&gt;&lt;strong&gt;touch&lt;/strong&gt;&lt;span&gt;.  Spend more than twenty minutes in front of the thinly-veiled and  glorified masturbatorium they call the primate exhibit, and you know  that there is &lt;/span&gt;&lt;em&gt;something&lt;/em&gt;&lt;span&gt; is going on in there. And, in fact, there is. As those sweaty little  monkeys wail away with a ferocity and single-mindedness rarely seen  outside of the realm of cage-fighting or professional tennis, they are  experiencing (first-hand) one of our most important senses in what is  possibly its most powerful avenue.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Touch  is, perhaps, our most vital sense. The associated mortality rate among  people with Peripheral Neuropathy (those who lack the sense of touch, or  ‘no-feelies’, as I am now nicknaming them), is far higher than with any  other sensorily deprived group. You need to feel things to survive.  It’s the most basic form of learning. It’s how we learn what’s going to  burn or stab us. Or both.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;I mean, think of the difficulty you &lt;/span&gt;&lt;em&gt;already &lt;/em&gt;&lt;span&gt;face  every morning when you turn on the shower. As you barely, just barely,  adjust that shower-nob, the water seems to alternately sway in between  bone-chilling ice-rain and boiling firewater. And even when you have it  barely balanced on an acceptable temperature, you better just pray  nobody flushes a toilet, or you don’t hit that knob accidentally with  your back.*&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So now imagine trying to adjust that fickle bitch shower &lt;/span&gt;&lt;em&gt;without &lt;/em&gt;&lt;span&gt;even  feeling it. What are you going to do? Guesswork? Good luck, you&amp;#8217;ll  freeze or burn! If you’re smart enough you’ll just skip it. But though  you’ve passed up the shower, you’ll still need to shave your face,  right? So, what, you’re going to put a razor to your neck &lt;/span&gt;&lt;em&gt;without knowing how hard you’re pressing&lt;/em&gt;&lt;span&gt;?  That’s suicide. So now you‘re living your life in a dirty, hairy mess  until one day a car mistakes you for a piece of smelly trash and boom.  You don’t even feel it. This is &lt;/span&gt;&lt;span&gt;exactly &lt;/span&gt;&lt;span&gt;how it happens.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Or  at least that’s how I imagine it. OK, back on track. If I haven’t  driven the point hard enough, I just want to state that touch is  important. But, much like our other senses, I’d also like to argue that  it’s &lt;/span&gt;&lt;u&gt;entirely deceiving&lt;/u&gt;&lt;span&gt; as well.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So,  lets do a little experiment, you and I. I want you to touch something.  No, not that, that’s not what we’re here for. Try a desk, or your  computer-screen. Something inanimate and solid. Seriously, do it, the  blog will wait.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;OK,  did you note that you’re hand did not go through the object? It  stopped, and you felt the pressure of your touch, and the object had a  texture and everything. It was whole, like you’d expect, right? I mean,  if what you were touching were 99.999999999% empty space (like I argued)  wouldn’t your hand pass right through as if you were swiping through a  thin mist? So it has to be solid, right?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Wrong. The thing is, at no point did you actually &lt;/span&gt;&lt;em&gt;physically &lt;/em&gt;&lt;span&gt;touch  whatever object you found. In fact, you never actually ‘touch’  anything, in the sense of making physical contact. There is always a  extremely small, but &lt;/span&gt;&lt;em&gt;very real&lt;/em&gt;&lt;span&gt; gap of empty space in between your hand and everything around you. What  you registered as the sensation of pressure was not the object, but the &lt;/span&gt;&lt;strong&gt;electrical repulsive force&lt;/strong&gt;&lt;span&gt; being emitted by it.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;It  works like this, and I’ll keep it simple: All atoms have a coat of  negatively charged electrons surrounding them, and like magnets, they  produce an extremely strong force repelling one another due to their  same charges (that’s our electrical repulsive force). So when the atoms  in your hand get close enough to the thing you appear to be touching,  really it’s just this electrical force keeping your hand’s atoms from  going any further. &lt;/span&gt;&lt;em&gt;The  sensation of pressure and texture is really the nerves in your fingers  registering a repulsive force of electricity, not a piece of physical  matter.&lt;/em&gt;&lt;span&gt; And so touch, just like hearing and sight, is absurdly deceptive in its  real nature. You don’t ‘touch’ something, you get close enough where it  electrically repels you, and then you feel that.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And  that’s it, that’s how we can feel the infinitesimally small array of  matter in our universe as the very ‘real’ and solid world around us.  Matter can be an extremely tiny part of the fabric of our universe and  still &lt;/span&gt;&lt;em&gt;feel &lt;/em&gt;&lt;span&gt;solid because we only register the repulsive force of electricity from these small flecks, not the physical flecks them-self. &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So  that’s it. That’s the end of my series on sensory perception. I’ve  explained all I wanted to, straight from the book, which again, is &lt;a title="Biocentrism" href="http://www.amazon.com/Biocentrism-Consciousness-Understanding-Nature-Universe/dp/1933771690" target="_blank"&gt; Biocentrism&lt;/a&gt;, by Robert Lanza and Bob Berman. (Again, read the book, it  has so much more than what I wrote about.) And though I’ve said all I  wanted, I would like to leave on this last comment:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;In the end, it’s our &lt;/span&gt;&lt;em&gt;own minds&lt;/em&gt;&lt;span&gt; that create this intense and vivid interpretation of a world that is  just barely there. We hear its vibrations, see its energy radiation, and  touch its electrical forces. And then, we take all this information,  this data from these faint specks of matter, and we unknowingly string  it together in a way so real, so seemingly sincere, that it could have  keep us fooled for eons, had not one person looked around him and  thought, “Yeah, but how?”&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;*I fucking hate showers.&lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/4017633945</link><guid>http://asilearnit.tumblr.com/post/4017633945</guid><pubDate>Tue, 22 Mar 2011 00:07:00 -0400</pubDate></item><item><title>Our Sexy Senses, (Part 2 Revision!):</title><description>&lt;p&gt;&lt;span id="internal-source-marker_0.6762651995674492"&gt; &lt;/span&gt;&lt;span&gt;Really,  I’m surprised it took me a whole three posts before I ruined science.*  Frankly I was aiming for two posts, and to be completely honest, a part  of me was really wishing I could do it in one. But no, it was my third  post (Our Sexy Senses; Part 2) where I started to describe real  phenomenon inaccurately. I said something wrong. So, in short, I need to take a step back and  revise something I said about the mechanics of sight:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;In  my attempt to simplify the description of how light and other EM  radiation is emitted and absorbed, I made an slight error. I falsely  oversimplified the concept, to a point where what I said is just  flat-out untrue.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So here comes the red pen. I ‘explained’ this:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;em&gt;When  light and other forms of EM radiation are energetically expelled into  our surrounding environment, atoms and molecules in the environment  absorb this radiation, re-emit it (at specific wavelengths, depending on  what types of atoms or molecules we’re talking about), and when that  re-emission hits our eyes, we register it as light and divide the  specific wavelengths into colors.&lt;/em&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So if I can just apply a few gentle correcting touches, we’ll have this:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;strike&gt;&lt;em&gt;When  light and other forms of EM radiation are energetically expelled into  our surrounding environment, atoms and molecules in the environment  absorb this radiation, re-emit it (at specific wavelengths, depending on  what types of atoms or molecules we’re talking about), and when that  remission hits our eyes, we register it as light and divide the specific  wavelengths into colors. These colors glue together in the form of  rainbows, where they then are absorbed through the skin, keep you from  playing sports, and make you gay.&lt;/em&gt;&lt;/strike&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Yes. That&amp;#8217;s right.  Just forget all of it. It’s wrong at a fundamental level. The reality  is a bit different; once light is emitted from an light-energetic source  (like a light-bulb), an object will absorb &lt;/span&gt;&lt;span&gt;some &lt;/span&gt;&lt;span&gt;of the wavelengths of that light and &lt;/span&gt;&lt;em&gt;reflect/bounce the rest back&lt;/em&gt;&lt;span&gt;. Not, like I stated, absorb all of them and re-emit them. What we see is reflected light that was &lt;/span&gt;&lt;em&gt;not &lt;/em&gt;&lt;span&gt;absorbed, as apposed to the direct emission of the light. (Unless you are staring straight at the source.)&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So  when you see something bright red, like a banana, maybe one that has  been painted bright red, you only ‘see’ it as red is because: The paint  covered banana itself absorbed all the wavelengths of light &lt;/span&gt;&lt;u&gt;except&lt;/u&gt; &lt;span&gt;for those in the EM spectrum that you register as red. The banana then  reflected ‘red’ light back into the environment where it hit your eyes  and made you question your choice in supermarkets. So in the end, and  much like my senior prom, what we end up seeing is EM Radiation and girls  that have been &lt;/span&gt;&lt;em&gt;rejected &lt;/em&gt;&lt;span&gt;by all else in our surrounding environment. (Again, unless we are staring straight at the light source.)&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;em&gt;Along  this vein: Something that appears white will have absorbed relatively  little EM radiation in the visible light scale, and will have reflected  the entire light-spectrum back (If you remember your color wheel, white is the combination of all colors). And something that appears black will  have done the opposite. It will have absorbed almost all the light,  reflecting very little back. This is an extremely important concept for  people who professionally work with dividing colors: mostly Kindergartners and  Republican Politicians.&lt;/em&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;OK,  now that I cleared that up, I’d like to make a final point. I titled  this blog “As I Learn It,” and at its core it’s really an experiment in  my ability to simplify and describe what I have &lt;/span&gt;&lt;em&gt;just &lt;/em&gt;&lt;span&gt;learned. So despite my best efforts, I&amp;#8217;m going to say something incorrect things from time to time. But this I will celebrate! Because finding yourself knee-deep in  wrong-as-shit is one of the most informative parts of  learning! So like I just did, I’m going to need to amend the incorrect things I am bound to say. And while I will be doing my best to  check my own factuality, please feel free to make frequent use of the  ASK button at the top of the page if you catch me before I do.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Alright, now let’s finish up this series with &lt;/span&gt;&lt;strong&gt;Touch&lt;/strong&gt;&lt;span&gt;!&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;br/&gt;&lt;span&gt;*This is why I can’t have nice things.&lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/4008917573</link><guid>http://asilearnit.tumblr.com/post/4008917573</guid><pubDate>Mon, 21 Mar 2011 16:54:00 -0400</pubDate></item><item><title>when will you be covering how love works?</title><description>&lt;p&gt;If I could answer that with any degree of certainty, I certainly would.&lt;/p&gt;
&lt;p&gt;I’m trying to cover only scientific principles and concepts that don’t require any guesswork of my own.

With that in mind, it’ll probably be a good idea to sum up some key points I made.&lt;/span&gt;&lt;span&gt; &lt;br/&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;&lt;span&gt;What we ‘see’ is electromagnetic energy (in the form of light) being radiated from an object, not the object itself.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Other than energy level (which manifests in frequency/jiggliness),  there is no physical difference between light and other forms of  electromagnetic radiation (such as radio waves, X-rays, ultraviolet  waves, ect.)&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;The human brain &lt;/span&gt;&lt;em&gt;interprets &lt;/em&gt;&lt;span&gt;different frequencies of light as different colors. Color is not something that exists outside the human mind.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Dolphins can communicate through complex whistles and are very intelligent. Friendly too!&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;&lt;span&gt;So  now that we have that covered, let’s move along. One of the new points  about sight that I’d like to make requires a bit of background in simple  atomic structure. It’s nothing too complicated, but the concept itself  will go against everything you thought you understood about the world  around you. No, really.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Fairly bold claim, right? Especially considering it’s about:&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;u&gt;Empty Space&lt;/u&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;To  talk about nothingness, we have to start small. Actually, small and  hairy. I mean of course, that we’re going to have to start with Greek  people. (But not the too-loud modern ones that can’t balance a  checkbook, no, for this we’re going to need a throwback.) We’re going to  need their greying and brainy predecessors, the &lt;/span&gt;&lt;em&gt;Ancient &lt;/em&gt;&lt;span&gt;Greeks*.  A society perhaps best known for its astounding contributions to the  fields of mathematics, general science, philosophy, and fat weddings.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The  ancient Greeks found (read: guessed) that physical matter could only be  divided so many times before it simply could no longer be broken up.  “Surely Thopolopogus,” one of them most likely said, “I could only halve  this rock so many times!”  As a society, they considered this a fair  call, and so they called such an elemental state “&lt;/span&gt;&lt;span&gt;&lt;em&gt;átomos&lt;/em&gt;,&lt;/span&gt;&lt;span&gt;” (a word from which we derive our term ‘&lt;/span&gt;&lt;strong&gt;atom&lt;/strong&gt;&lt;span&gt;’)  and called it a day. While they were right (luck), they also thought  that the atomic elemental states were composed of like, fire, and water,  and other ridiculous things like that, so feel free to scoff at them.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The  reality is much more complicated. We modern humans know that really,  atoms break down into 117 known elements (gold, helium, more gold, ect.)  which are themselves actually made up of even smaller particles  (protons, neutrons, and electrons) and some of &lt;/span&gt;&lt;em&gt;those&lt;/em&gt;&lt;span&gt; are made up of even smaller sub-particles (quarks, gluons,  johnstamosons, ect.) So like I said, it’s complicated, but luckily  enough for us, we don’t need to know a lot of that right now. For all  our intents and purposes, we just need to know that on an extremely  small scale, almost every piece of known matter can be broken down into  atoms that are (for our general purposes) shaped very similarly.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;They  are shaped like this: A small core of tiny pieces of matter (protons  and neutrons) that is orbited by one or more even tinier pieces of  matter (elections). For most people, this is nothing new, you’ve either  heard about this in a science class or seen a drawing of an atom at some  point during your life. One could imagine that an atom looks a lot like  the earth being orbited by the moon. But here is the important aspect  of the atomic structure I want to highlight: It’s not necessarily the  shape I want to focus on, it the &lt;/span&gt;&lt;em&gt;scale &lt;/em&gt;&lt;span&gt;of the damn thing.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The ratio of physical matter to empty space within an atom is unbelievably small. There is &lt;/span&gt;&lt;u&gt;hardly any&lt;/u&gt;&lt;span&gt; physical mass in an atom. I could use numbers to describe this, and I  will in a moment, but just for perspective let’s view this in good ol’  fashioned American terms. If I blew an atom up to the size of a  football-field, do you know how big the nucleus of it would be? The size  of a fly. And the electron zooming around it? Unviewable still. And the  numbers? An atom is 99.9999999999999% empty space, and yes, that is&lt;/span&gt;&lt;span&gt; &lt;/span&gt;&lt;span&gt;the exact number of nines.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And  here is the part that still blows my mind: Though an atom is almost  completely empty space, that’s absolutely nothing when compared to the  amount of dead nothingness &lt;/span&gt;&lt;em&gt;between &lt;/em&gt;&lt;span&gt;atoms  (even ones that are relatively tightly compacted). A group of atoms is  essentially a vast expanse of nothingness with only a few tiny flecks of  mass. And when you add in what we, on the macro-scale, consider to be  considerable gaps of empty space, I cant even begin to describe how  little physical matter is there. &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;The  reality is that there is an absurdly small amount of physical matter  surrounding us, so little that it’s almost negligible. Far, far less  than .0000000000000000000000000000001% (that one I did just add zeros at  random, but trust me it’s way less than what I even wrote.) So what  does this have to do with the sensory perception, what does this have to  do with sight? Well, simply put, if there is almost no mass in the  universe, why do I see shit? Look around where you are right now, do you  see things? See a computer? Looks like it’s there, right?&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;It  is, but just barely. That computer is almost absolute nothingness with  hardly a skeleton frame of flecks of physical matter. So again, then why  do I see things if they’re barely there? Well, this takes us right back  to the first key point I made at the top of this post. Go back and  reread it. Simply restated, we don’t ‘see’ objects, we see their energy  radiation. The reality is, that if you &lt;/span&gt;&lt;u&gt;could&lt;/u&gt;&lt;span&gt; &lt;/span&gt;&lt;span&gt;see  physical objects in their true nature, there would just be nothing to  see, just a blank expanse of colorless (remember key point number 3,  color is an interpretation of frequency and doesn&amp;#8217;t exist outside our  minds) and empty nothingness. What you see is the energy being radiated  off these slight flecks of matter, and your mind (also composed in the  same way) figured this together into an image that couldn’t be less true  to reality. You see something that looks whole, but it isn’t.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So  well, that’s a hell of a thing? Now let me state, because I’m sure this  is starting to sound like pseudo-science, that there is not a single  bit of what I’m saying that is in the least contested by any actual  scientist. Most of our existence is empty air, and we don’t register  that because our visual perception is an interpretation of EM radiation,  not an objective view of reality. It’s fact.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;So  here is a question. If most existence is empty space, why can I feel  things? Oh! Good question, especially because the last part of this  series is on &lt;/span&gt;&lt;strong&gt;Touch&lt;/strong&gt;&lt;span&gt;!&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;*The first society completely run by nerds.&lt;/span&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/3760259946</link><guid>http://asilearnit.tumblr.com/post/3760259946</guid><pubDate>Thu, 10 Mar 2011 02:36:00 -0500</pubDate></item><item><title>Our Sexy Senses, Part 2.</title><description>&lt;p&gt;&lt;span&gt;So, before I embark my explanation of this absurd miracle we call  &amp;#8216;sight&amp;#8217;, I&amp;#8217;d like to make a quick aside. It will only take a second, and  I think it&amp;#8217;s fairly important. It&amp;#8217;s this:&lt;/span&gt;&lt;br/&gt;&lt;span&gt; &lt;/span&gt;&lt;br/&gt;&lt;span&gt;I want to note that I&amp;#8217;ll be using all of my personal restraint to &lt;/span&gt;&lt;u&gt;not&lt;/u&gt;&lt;span&gt; spend this entire blog making fun of the blind. While far too easy, I&amp;#8217;d  like to set an example and show that I&amp;#8217;m mature enough to look beyond  such mean-spirited jokes. Strong enough to even see past this potential  comic goldmine. In fact, I want the entire blind community to know that I  am watching over them, and that I have a vision: That one day, we will  all be able to gaze over our differences and view one another through  the lens of personal character, not on how poorly we function in a game  of dodge-ball.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;I see this vision with perfect 20/20, blind-people. And I hope you  know, that if anyone is behind you and your strange, bat-like society of  sightless humanoids, it is me, blind-people, it is me.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;People with glasses though, oh man, you guys are in for it.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;u&gt;Sight&lt;/u&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Physical sight is, arguably, the sense we rely on the most.* And while  some of us can and do lead what could hesitantly be called full and  meaningful lives without it, (I&amp;#8217;m looking at you blind-people!) try  taking away somebody’s glasses.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Watch how weak and disoriented they become. In fact, stare them down as  they feebly grasp at the empty air around them, all the while  discovering first-hand the sharp corners of our collective,  three-dimensional world. Pity them for this genetic, or age-induced  weakness. But as you do, realize that you too could become like this, in  the event of a night-time power-outage or during a riveting game of  pin-the-tail-on-the-donkey. Reflect on how much easier living is with  your fantastic ability to see things, and realize how much different  existence could be without sight. And when you&amp;#8217;re done, and you  understand all this, give back the glasses you took, because you&amp;#8217;re  being kind of an asshole.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;What is odd then, for something we rely on so much, is how principally  deceiving it is. Much like my conclusion on hearing, I&amp;#8217;d like to show  that the fundamentals of sight (color, solid appearance, and more) are  largely a fallacy of our own minds.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Generally, we tend to think of our eyes as windows, things with which  we view the untainted natural word around us. When we look at something,  let&amp;#8217;s say a crying baby, one that we are shaking uncontrollably, we  believe that we are beholding the physical, crying object in its  entirety. Objectively, what we are seeing is purely the baby itself.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;This though, is perhaps the biggest misconception we can hold about our  sense of sight. We never actually &amp;#8216;see&amp;#8217; an object on its own, rather,  what we register is the physical energy (in the form of photons) being  produced by it. In reality, energy radiation is all we ever &amp;#8216;see&amp;#8217;,  nothing more, and the implications of this are phenomenal. But before we  get to them, lets first go over the physical process of sight itself.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;We&amp;#8217;ll start small. Literally. The basic components of matter, atoms,  are constantly transferring and radiating energy. This radiant energy is  commonly referred to as &lt;/span&gt;&lt;strong&gt;electromagnetic radiation&lt;/strong&gt;&lt;span&gt;, and we refer to a single particle of this energy as a &lt;/span&gt;&lt;strong&gt;photon&lt;/strong&gt;&lt;span&gt;. &lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Though  we only register a small portion of it, everything around you is  radiating electromagnetic energy almost all the time. Light,  radio-waves, microwaves, x-rays, and a host of other waves are all types  of this electromagnetic radiation. They are simply energy that is  emitted by atoms and, with only one exception, they are all exactly the  same. The only difference between types of electromagnetic radiation  (which will henceforth be called EM radiation) is they they can differ  in frequency, which is simply the rate at which they jiggle.&lt;/span&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;The higher/faster the frequency/jiggliness (Scientific term? It is  now.) of a particle of EM radiation, the more energetic it is. So while a  very high-energy stream of EM radiation, such as a beam of gamma rays,  can rip through your face with its energy level, very low-energy streams  like radio-waves, are harmless. They can only remind you how old you  are because who still uses the radio? (Nice try Sirius radio, but I  think we&amp;#8217;ll be able to see the Kaiser&amp;#8217;s incoming zeppelins without your  help.) I also want to restate that we are constantly surrounded by an  entire spectrum of relatively low-energy EM-radiation (not the face  ripping kind), because as I said, that stuff is being  emitted/transferred by atoms&lt;/span&gt;&lt;em&gt; all the time&lt;/em&gt;&lt;span&gt;.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Now that we understand EM radiation, let&amp;#8217;s talk about an extremely  small portion of it. Hell, let&amp;#8217;s talk about the section of EM radiation  that has a frequency between 400 to 790 terahertz. Why? Because we call  this section &lt;/span&gt;&lt;strong&gt;visible light&lt;/strong&gt;&lt;span&gt;, and it is essentially a &lt;/span&gt;&lt;em&gt;completely arbitrary&lt;/em&gt;&lt;span&gt; fragment of the entire spectrum of EM radiation. The only thing that differentiates light from the rest of the electromagnetic spectrum is us.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;Though, by &amp;#8216;us&amp;#8217;, I mean of course the 8 million cone shaped cells in  the human retina. Depending on the jiggliness of the incoming light,  (though still within our seductive 400-790 terahertz sweet spot)  different cones in the retina will be stimulated, each of which are  tuned to interpret different frequencies as different &lt;/span&gt;&lt;span&gt;colors&lt;/span&gt;&lt;span&gt;.  These cones will send a corresponding electrical impulse to the  occipital-lobe of the brain, where boom, we create a mental picture.  Everything you &amp;#8216;see&amp;#8217; is an interpretation of an arbitrary slice of  radiation, which the mind magically color-codes based on jiggliness.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;In action, the entire process works like this: Say it’s dark in your  bedroom, (in scientific terms, that the room is radiating a negligible  amount EM radiation within the visible-light spectrum), and you’d like  to, well, &lt;/span&gt;&lt;em&gt;see things&lt;/em&gt;&lt;span&gt;.  So you turn on a light-bulb. The now energetic light-bulb expels and  saturates the entire room with a whole range of EM radiation, including  visible light. The furniture and whatnot within the room thereby absorb  this radiation,and transfer it back into open space. (Depending on the  structure of the atoms and molecules in the furniture, different  frequencies of light are transferred back during this process i.e.  different colors) Some of the radiation that is reflected back into open  space will fall upon our eyes. If the radiation is within our arbitrary  spectrum, it will stimulate the rods in our retinas. Our eyes then  transfer the information of which cone was stimulated and where, to our  brain, which color-codes this information and assembles it as a picture.  This happens hundreds of times per second, and when strung together,  these pictures make the movie-reel style sensation of &lt;/span&gt;&lt;strong&gt;sight&lt;/strong&gt;&lt;span&gt;.&lt;/span&gt;&lt;br/&gt;&lt;span&gt;&lt;/span&gt;&lt;br/&gt;&lt;span&gt;And this is absolutely insane for dozens of different reasons, but I’ll get to that in my next post.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;br/&gt;&lt;span id="internal-source-marker_0.00034924033098038265"&gt;*This claim is not based on hard, scientific fact, but try driving blindfolded.

Normally it would be a text, but in this case it is &lt;a title="Biocentrism" target="_blank" href="http://www.amazon.com/Biocentrism-Consciousness-Understanding-Nature-Universe/dp/1933771690"&gt;&lt;em&gt;Biocentrism&lt;/em&gt;&lt;/a&gt;, by Robert Lanza and Bob Berman. It&amp;#8217;s quite interesting, and I highly suggest that you read it. I am stealing nothing from it but the hard science, a process I assume is legal. I&amp;#8217;m kind of banking on &amp;#8216;legal&amp;#8217; right now.)&lt;/p&gt;
&lt;p&gt;Alright Science, let’s start with something personal. Let&amp;#8217;s talk about our &lt;em&gt;feelings&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;And by that, I mean our sensory perception.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Our Sexy Senses, Part 1.&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;So our senses, the physical processes which reveal what our existence looks, sounds, feels, smells, and tastes like. The tools we use every second to find food and water, recognize danger, navigate, watch cable television, and decipher if or when we’re on fire.&lt;/p&gt;
&lt;p&gt;As any blind person knows, these senses are very important. They’re the only connections we have to anything outside our bodies, and they are also, as I will explain, far more complex and illusionary than we ever give them credit for. So lets start!&lt;/p&gt;
&lt;p&gt;For the most part we, as human beings, have five specific senses. Touch, hearing, sight, smell and taste*. For brevity’s sake, I will discuss only the first three, hearing, sight, and touch.&lt;/p&gt;
&lt;ol&gt;&lt;p&gt;&lt;u&gt;Hearing&lt;/u&gt;&lt;/p&gt;
&lt;/ol&gt;&lt;p&gt;As a general rule, we hear things. Be it language, music, or the disappointed scoldings of our loved ones, we are constantly surrounded by sound. But how does it work, and what physical process does our body go through to register sound? Great question William, lets find out.&lt;/p&gt;
&lt;p&gt;First off, &lt;strong&gt;sound&lt;/strong&gt; can be defined as &amp;#8216;the disturbance or vibration of a medium&amp;#8217;. In even simpler terms, sound is the movement of a medium. (The specific medium can be anything: air, water, steel, or the absurdly thin drywall separating you from the frantic humpings of your neighbors.) Any sound we hear is simply vibrations around us, and if it is energetic enough (think rock-concert) we can even readily feel it through our skin.&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Side note: Because sound is only the motion of a medium, without a medium, such as in space, there is no sound at all. In space, there is nothing to be vibrated, which is one reason why we cant hear angels, and why a space-concert would be a horrible waste of money.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;So when someone speaks to us, back here on earth, all they are doing is vibrating the air around them. They send out tiny pulsations of wind from their mouth, which hit our ears. These vibrations then move through our ears and vibrate against the sensitive membrane of skin we call our eardrums.&lt;/p&gt;
&lt;p&gt;It&amp;#8217;s here on the eardrum that the magic of &lt;strong&gt;hearing&lt;/strong&gt; happens. Sound has no intrinsic property beyond being a puff of air, it&amp;#8217;s just a vibration. But when our eardrum vibrates with sound, the information of that vibration is transferred to the brain, where the temporal lobe interprets it, based on its size and rate of movement, as a &lt;span&gt;&lt;strong&gt;noise&lt;/strong&gt;&lt;/span&gt;.&lt;/p&gt;
&lt;p&gt;There is a key difference I want to make about &lt;strong&gt;noises&lt;/strong&gt; and &lt;strong&gt;sounds&lt;/strong&gt;. Sounds are the movements of air around us, and noises are our brain&amp;#8217;s interpretation of those sounds.&lt;/p&gt;
&lt;p&gt;So why am I making this differentiation? Two reasons.&lt;/p&gt;
&lt;ol&gt;&lt;li&gt;
&lt;p&gt;&lt;strong&gt;Sounds&lt;/strong&gt; are &lt;em&gt;all&lt;/em&gt; the pulsations and vibrations 	around you. &lt;strong&gt;Noises&lt;/strong&gt; are just a very small subset of these 	sounds. You will only &amp;#8216;hear&amp;#8217; a sound in the air around you if it is 	pulsating at 20 to 20,000 vibrations per second. Anything vibrating 	faster or slower than that you will not hear. In fact, as you age, 	to lets say at age 40, the upper limit of the sounds you can hear 	drops off to around 10,000 vibrations a second. Different animals 	also have different ranges of sounds they can hear. Dogs can hear 	whistles at a much higher frequency (vibration rate) than people. 	Likewise, whales can hear much lower frequencies, such as the 	deep-sea drills that we consider silent. This makes them sad, and 	their tears are why the ocean is so salty. Back to my point though. 	Because there are sounds we can and can not hear, &lt;em&gt;noises are just 	a small, random subset of sounds&lt;/em&gt;.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;The second reason I am making a delineation between noises 	and sounds is because I would like to emphasize this: &lt;em&gt;Noises only 	exist inside our own heads&lt;/em&gt;. Until you hear something, all it 	exists as is a puff of air in your surrounding environment. Hearing 	is the process of transferring information from your eardrum to the 	temporal lobe of your brain, where it is then &lt;em&gt;interpreted&lt;/em&gt;. So 	it is only when you &amp;#8216;hear&amp;#8217; these vibrations that your brain 	registers them as noises like clapping, music, speech, gunfire, 	screaming, or more gunfire and whatever. Before you hear something, 	all it is is a vibration hanging in the air.&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;&lt;p&gt;So &amp;#8216;Hearing&amp;#8217; as a sense, is not only the registration of just a small subset of all sounds/vibrations, but it is also the mental interpretation and &lt;em&gt;&lt;span&gt;creation&lt;/span&gt;&lt;/em&gt; of &amp;#8216;noises&amp;#8217;.&lt;/p&gt;
&lt;p&gt;Example: When you sit in your car, with the music at top volume, all that is happening outside of your own head is that the car&amp;#8217;s speakers are rhythmically pulsating the air at specific frequencies, creating a very specific stream of air-puffs. There is no music in that car, no fat baseline, no rocking guitar solo, just noiseless puffs of air. Free Bird flies free only in your head.&lt;/p&gt;
&lt;p&gt;The point I want to make is that your brain is a liar. A dirty liar. Though we don&amp;#8217;t actively register this, noises are not something that exist in the outside world. They are a creation of your own mind. Your sense of hearing is no more &amp;#8216;real&amp;#8217;, than lets say&amp;#8230; the random colors in your eyes when you press your eyes really hard with your thumbs. They&amp;#8217;re a mental creation.&lt;/p&gt;
&lt;p&gt;Actually, while we&amp;#8217;re on the topic. Press your thumbs into your closed eyes. Just do it. Don&amp;#8217;t think about it, do it. Experience them colors. Because our next sense is &lt;strong&gt;Sight&lt;/strong&gt;!&lt;/p&gt;
&lt;p&gt;&lt;br/&gt;&lt;br/&gt;&lt;/p&gt;
&lt;p&gt;* Some of us have a rare ‘sixth sense’, but this sense is scarce, and limited to only a handful of chosen people (Bruce Willis), so we will ignore it.&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/3631623298</link><guid>http://asilearnit.tumblr.com/post/3631623298</guid><pubDate>Thu, 03 Mar 2011 21:10:00 -0500</pubDate></item><item><title>An Introduction</title><description>&lt;p&gt;&lt;!--[if gte mso 9]&gt;&lt;xml&gt; &lt;w:WordDocument&gt; &lt;w:View&gt;Normal&lt;/w:View&gt; &lt;w:Zoom&gt;0&lt;/w:Zoom&gt; &lt;w:PunctuationKerning /&gt; &lt;w:ValidateAgainstSchemas /&gt; &lt;w:SaveIfXMLInvalid&gt;false&lt;/w:SaveIfXMLInvalid&gt; &lt;w:IgnoreMixedContent&gt;false&lt;/w:IgnoreMixedContent&gt; &lt;w:AlwaysShowPlaceholderText&gt;false&lt;/w:AlwaysShowPlaceholderText&gt; &lt;w:Compatibility&gt; &lt;w:BreakWrappedTables /&gt; &lt;w:SnapToGridInCell /&gt; &lt;w:WrapTextWithPunct /&gt; &lt;w:UseAsianBreakRules /&gt; &lt;w:DontGrowAutofit /&gt; &lt;/w:Compatibility&gt; &lt;w:BrowserLevel&gt;MicrosoftInternetExplorer4&lt;/w:BrowserLevel&gt; &lt;/w:WordDocument&gt; &lt;/xml&gt;&lt;![endif]--&gt;&lt;!--[if gte mso 9]&gt;&lt;xml&gt; &lt;w:LatentStyles DefLockedState="false" LatentStyleCount="156"&gt; &lt;/w:LatentStyles&gt; &lt;/xml&gt;&lt;![endif]--&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;The idea for this blog has been in my head for quite a while now. And, like all potentially bad ideas, it started as a series of questions of the ‘why not?’ variety. Simply put, they were these:&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;!--[if !supportLists]--&gt;&lt;span&gt;1. &lt;/span&gt;Why not write a blog explaining the fundamental principles of as many of the branches of science as I could tackle?&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;!--[if !supportLists]--&gt;&lt;span&gt;2.&lt;span&gt; &lt;/span&gt;&lt;/span&gt;And why not do it in a way that would be easily accessible and engaging to the nonscientist?&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;!--[if !supportLists]--&gt;&lt;span&gt;3.&lt;span&gt; &lt;/span&gt;&lt;/span&gt;&lt;!--[endif]--&gt;And why not try to make it funny?&lt;/p&gt;
&lt;p class="MsoNormal"&gt;Yes, why not?&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;Well if I did, I’d have a hell of a thing, I concluded. I mean, really why not? After all, what could be easier than to fundamentally break down, order, explain, and humorize thousands of years of human achievement?&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;And who better to do it, than me, William Herkewitz? A 21 year old college graduate with a bachelors in English literature, and only the most basic understanding of the sciences.&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;Maybe I’m not giving myself enough credit. Over the last year, I’ve read a few theoretical science books, mostly on math and physics, which have been marketed specifically toward people like me: ‘Laymen’, people with the interest, but almost none of the education. And what I’ve found so far as been both fascinating and endlessly hilarious. And despite my limited knowledge, I find myself talking about what I have recently read with little to no insistence, and sometimes even despite moderate resistance.&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;I’ve come to realize that in humanity’s search for the big answers: Who are we, why are we here, how does it all work, why does this make me so gassy? All these desperate scrambles for answers have come up with some of the most interesting stories, far fetched theories, and brilliant insights.&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;They’re absurd. They’re funny. And I want to know more. So here is what I am going to do:&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;&lt;/span&gt;Going along with the blog’s title, I’m going to write what I learn, as I learn it. I’m going to study and decipher the sciences to the best of my ability, and in some crude pattern write down the explanation and summaries of what I have most recently learned. I’ll teach straight out of my books, stick to the scientific method, and give credit where credit is due. I’ll do my best to be accurate and concise, without sacrificing the factuality of the subject, and then I’ll make dick jokes, but not really.&lt;/p&gt;
&lt;p class="MsoNormal"&gt;So let’s see how this goes!&lt;/p&gt;
&lt;p class="MsoNormal"&gt;-William Herkewitz&lt;/p&gt;&lt;/p&gt;</description><link>http://asilearnit.tumblr.com/post/2758490114</link><guid>http://asilearnit.tumblr.com/post/2758490114</guid><pubDate>Sat, 26 Feb 2011 16:20:00 -0500</pubDate></item></channel></rss>
