...or maybe not. Honestly, I'm a math major, but whenever interesting research comes up, it's about biology (heck, this is the first post on my blog that even has the "math" tag). Is it that the barrier to entry for interesting math research is way, way too high for me? Probably. I could post about how interesting I find the Twin Prime Conjecture and the Riemann Hypothesis and infinitely differentiable Riemannian manifolds (Bozhe moi), but I'd just be doing a vaguely boring rehash in most cases. Oh, exception: I find it really neat that the Cantor set contains an uncountably infinite number of points (and the proof of this is really neat, too, and illuminates the name 'Cantor ternary set'), that these points are arranged in segments, and that it still has measure 0 (that is, if you add up the length of all the segments in the set, it sums to 0). Fractals = mindscrew.
This brings me neatly to the subject of evolution. No, really. Woese and Goldenfeld claim that collective evolution, mediated by lateral gene transfer, should dominate our understanding of the formation of genetic novelty in early life. I'd try to give a better summary the way I did last time, but the topic is too big and the paper is too small and I just don't know enough. Upshot: I need to start taking biology again next semester. Oh, and there's a new paradigm of understanding biological innovation and all that.
Query: I seem to recall that some 5-8% of the human genome is sourced from endogenous retroviral DNA...in light of that, how should the collective view of evolution described above influence our understanding of the interaction between extremely complex organisms (like us) and extremely simple ones (like the virii)? Also, can I use virii as a word? Some things to look into.

You know you're a nerd when...
Since I made a nice long compilation of these, I figure I might as well put them somewhere convenient. Here goes.
You know you're a nerd when...
When you write page-long Facebook comments about *serious business*. Heck, when you write page-long Facebook *anything* about serious business.
When your choice of favorite hang-out ends with a TLD.
When Feynman is a household name.
When you verbalize your actions with Net slang. A laugh is just a 'lol', a sigh is just a *sigh*...
When the Rules of the Internet are more familiar to you than the Rules of Fight Club.
When you go to Sporcle to train.
When you prefer Primer to Avatar.
When Neo first shows off his powers irl and you think, "Oh shit, they're embedded in nested Matrices!"
When you are ashamed of your sesquipedalian loquaciousness.
When you decide that referencing xkcd for nerd cred is cheating.
When you bet on the inclusion of one preposition in one line of one book. (It's "Aragorn sped *on* up the hill." Obviously.)
When Twenty Questions really means "Keep asking till you give up."
When the food is problematic.
When you cannot get through the day without your fix of silly cats.
Alternatively, when you disdain silly cats, but think silly dogs are the shit.
When you're good friends with someone you've never met in meatspace.
When you're at the bookstore, and start riffling through a book to see if you want to buy it...and realize, a while later, that it would be pointless to buy a book you've already read, and also that the sun's gone down.
When you consciously verb nouns. Double points if that makes you think of Calvin and Hobbes.
When you make sure your [sarc][/sarc] tags are properly formatted.
When weirdness becomes a goal to attain rather than a quality to shun.
When you are a Timmy, Johnny, or Spike. Melvin or Vorthos? Okay, now you're just a smartass.
When the fate of your debate rests on a fictional planetary ecologist.
When you feel a compulsive need to use xor to remove logical ambiguity.
When you are familiar with the Laws of Poe, Sturgeon, Godwin, Moore, and Finagle.
When TV Tropes ruins your vocabulary.
When you describe Jesus as a subclass of God that implements the Human interface.
When the zeta function is elementary. (Except when it isn't.)
When you think that Transcendentalists must not have liked polynomials very much.
When you worry about the effects of drunkenness on your mental math.
When your response to use of the words pneumonoultramicroscopicsilicovolcanoconiosis, electrophotomicrographically, and floccinaucinihilipilification is something other than "Gesundheit".
When you worry about your use of the Oxford comma.
When your reaction to hearing about Homo floresiensis is to muse that Tolkien was telling the truth all along.
When you join a party by making a charsheet.
When you realize that the Ringworld is unstable.
When you consider the joke "there are 10 types of people in this world, those who understand binary and those who don't," and its higher-base variations, to be old hat.
When your chat with a friend bounces between nontrivial reasoning in philosophical thought experiments and appropriate balance for interacting feats/spells in D&D.
When you start dismissing nerdy pickup lines because the math/science involved is too elementary.
When, in your conversations, the term "lawyer" refers to a gaming pedant rather than the profession.
When the Chinese in Firefly breaks immersion because it's really BAD Chinese, or the dialect changes mid-episode.
When your bedside table reading pile is really a bedside table, three desk shelves, the top of your clothes drawer, and the lower bed bunk--and you leave the room at 3 AM to go find a different book.
When you lose The Game.
When you feel a little sad inside that someone, somewhere, knows more digits of Pi than you.
When hearing a relatively obscure mathematical term causes you to break out in song (Mandelbrot set, anyone? Bonus points if you started singing on 'Julia set' instead).
When you sit down to read all the goddamn codex entries in Dragon Age.
When you start min/maxing your Pokemon's attributes.
When you've been clicking on the 'random article' button for the last two hours.
When you find yourself having to choose between chess and go for the next game.
When you lol irl.
When people compliment you on your Renfaire or cosplay costume.
When you are genuinely outraged that Tom Bombadil got replaced by a random encounter with wood-elves, and then wonder whether those wood-elves were more likely to be Sindarin or Noldorin.
When you have tried to memorize the elements...lyrically.
When you show up to your school's traditional first-day hazing...wearing your self-made chainmaille coif.
When Quenya is your second language.
When you rack your brains thinking of ways to contribute to this list.
********************************************
(note: about 95% of these are actual self-reference, but not all.)
More will be added below when appropriate.
If, at any time during the last 525,600 minutes, you have mused on the diminishing cost of a gigabyte of memory...you might be a nerd.

Biology is Weird
...and that's one reason why I like it. Consider: the selective inefficiency of complex organisms like mammals is one reason why we become more complex, according to a recent paper published in Genome Research. In simple, rapidly reproducing organisms like our single-celled cousins, gene duplications get eliminated reasonably quickly because they're a resource drain. But in complex organisms that tend to have smaller populations and longer generation times, these redundant paralogs can survive, and this often leads to specialization as paralogs diverge via mutation. I mean, it's not all that surprising to consider gene duplication as a significant mechanism for introducing variation and complexity (once you realize that it happens, anyway), but the idea that these occurrences depend on our poor selection is kind of a mind-bender.
...on an unrelated note: looking at this post, I realized that I'm falling prey to sesquipedalian loquaciousness, i.e. I'm using more big words than I need to. That's not good, even for my writing seminar--I bet profs get annoyed by roundabout expressions and overly complex language just as much as any other reader. Time to cut back. (...I think it's working!)
