If you'd like to get a better sense of who I am, spend a little time comparing our answers. I really went bananas with the questions, answering over 2,000 (so many, in fact, that virtually all the ones left are intended for Brits.)
I have to add that OkC has misjudged my personality. They say I'm far worse-mannered than average, but in truth I'm actually very polite. For example, I couldn't bring myself to ignore someone who's taken time to write me a message. I think the problem is just that algorithms don't understand self-deprecating humor yet.
As you'll see from my comments on various answers, I have strong opinions, and many are considered eccentric or unconventional in this neck of the woods. But I'm a thoughtful person, and I don't mind strong opinions that differ from mine. There's hardly anything I enjoy more than trying to figure out the world, to identify laws and patterns, and to understand how things work. I love to share that quest with others who find it pleasurable, whether we incline toward the same kinds of conclusions or not.
BOOKS: A long time ago I made the decision not to read any fiction (with a few exceptions). My literary friends tell me this makes me a philistine, but at least I'm a philistine who knows a little bit about how the world works. My reasoning was that (1) I really enjoy learning about reality, and (2) there's only so much time and mental space one can give over to reading. So I read nonfiction pretty much exclusively, dividing my time more or less equally between technical math and physics, analytic philosophy and philosophical logic, popular accounts of contemporary science (mostly biology, economics, and psychology), works on technology, engineering and the future, reconstructions of the early human past, episodes of recorded history, and anything on survival, primitive living skills, and permaculture (small-scale, self-sustaining, closed-cycle agriculture). I also read lots of news/analysis sites, blogs, and specialty sites (particularly about nuclear energy and space exploration, two subjects I find extremely fascinating).
MOVIES: Movies are just entertainment for me. I'll risk admitting, a bit sheepishly, that I have a weakness for terrible martial arts movies, and I own every Steven Seagal movie ever made (including and especially the ones that went straight to DVD, which all contain a love scene in which Seagal goes to bed with his wife wearing a long leather coat). Some recent favorite movies have focused on the early 1960s, which I see as a kind of golden age. To mention one, I really like "Thirteen Days", about the Cuban Missile Crisis (JFK is one of my heroes). It features Kevin Costner doing an even worse Massachusetts accent than his English accent from Robin Hood, but somehow despite that it manages to be one of the best movies I've ever seen.
SHOWS: I don't have a TV or particularly like TV (it was so much better in the 70's... where have you gone, Columbo?).
MUSIC: I have unusual taste in music. As a kid, I lived for blues and classic rock (Clapton, Beck, etc.), which led me to pick up the guitar. I never got very good at that, but the lasting effect was that it strongly colored the way I hear and appreciate music. Most of what I listen to now is guitar-driven or string-driven in some way: from Bach lute suites to medieval harp music, to percussive acoustic guitar instrumentals, to my current favorite: sexy 80's fusion jazz (that's right, I did say "sexy 80's"). Here's a piece I really like, which builds gradually in intensity: https://www.youtube.com/watch?v=X48DXt8Jn7M. I also listen to Israeli jazz, Pakistani pop (Coke Studio Pakistan is one of the best things ever made), Coltrane, Haydn, Native American flute songs, etc. It's all weird, but I think all good.
FOOD: Basically, I just like all food. Some favorites: Middle Eastern (best of all Turkish), Mexican, Indian, German (a good bratwurst with sauerkraut and beer is heaven for me), Vietnamese, French, Thai, Italian, Japanese, Chinese, Ethiopian.
By the way, "F-Li-Be" is a chemist's shorthand for a solution of lithium fluoride and beryllium fluoride. It's a molten salt solution in which nuclear fuels such as thorium can be dissolved and burned up in a beautifully efficient and inherently self-stabilizing reaction. I believe this reaction could be the key to the next chapter in the development of technological civilization. I guess it's pretty strange for a dating site username, though.
