[03 Nov 2010|05:39pm] mothwentbad I used to be annoyed that when I text "fuck" it defaults to "dual", but lately, it's just made functional analysis more interesting to think about. e.g.: Let X be a set of people. Let X^* be the set of people they've "dualed" (the "dual" space of X). Show that X^** := (X^*)^* contains X. EDIT: OK, the statement isn't necessarily true unless you exclude the possibility that X has virgins. I'd have to find a texting-homonym for "Banach" to make this fact funny, though. 5 comments|post comment

Math music? [03 Aug 2010|11:22pm] gemini6ice I'm looking for songs about math or tangentially related to math, numbers, or counting. I'm specifically concerned with the lyrical content, not mathematically-devised melodies or instrumental backing (such as mathrock). Any suggestions? So far I have: Mathematics Little Boots Who's Stopping You? Semisonic Three Small Words (JatP Theme) Josie and the Pussycats Finite Simple Group (of Order Two) The Klein Four Group Wednesday Fischerspooner Pi Hard 'n Phirm The Multiplication Song Animaniacs Sixteen Military Wives The Decemberists Happy Endings The All-American Rejects 23 comments|post comment

song about the Fibonnaci Sequence [25 Jun 2010|01:05am] parallel_rose Psyche Corporation has a song called "Whirring World" about the Fibonacci Sequence.. You can hear it here: http://www.myspace.com/psychecorp ..I couldn't find any better-quality versions on youtube as all the youtubes are of live performances so it's harder to hear the numbers distinctly. Lyrics: http://psychecorporation.com/lyrics/ww.html The song we're currently working on features the DNA sequence from the poliovirus, but that's not done yet. post comment

Bertrand Russell tattoo. [15 Jun 2010|06:20pm] lamregcinerhp Hello. I'm having a friend design for me a Bertrand Russell tattoo and I want to have something symbolic flanking the tattoo besides just his portrait. Russell's famous paradox of course jumps to mind, but when I look up the form written in modern mathematical notation it becomes quite long (and my shoulder is quite small). I'm not sure where I can find the core defining elements written in Russell's original notation (specifically, defining a set containing all sets not containing themselves). Can anyone help me on this or does anyone have any other ideas? Thanks a lot. 20 comments|post comment

Math is like cake [27 May 2010|12:21pm] math_fridge Math is like cake: It is easy and delicious to consume, (though sometimes it may be too dense and cause you to forget to feed yourself anything else that day). If you bake one from a known recipe, it will probably be good, (unless it was designed as an excuse to use some exotic ingredient that we don't really know what to do with yet, regardless of how useful for consumption the result is). If you don't use a recipe, when the result falls apart or tastes awful, it is not always obvious where you went wrong. If you bake a good one without writing down what you did, it doesn't count because you'll probably never be able to reproduce it. If you develop your own recipe, you'll find that getting it into a cookbook so that others can use it is very difficult. (But you can always post it online.) Who can think of more ways in which math is like cake? 5 comments|post comment

Erotic Equations? [13 Apr 2010|06:11pm] skreidle Erotic equations: Love meets mathematics on film | CultureLab | NewScientist -- [Sex and math may not be the most obvious pairing, but Edward Frenkel knows otherwise. The 41-year-old mathematician and professor at the University of California, Berkeley, sacrificed his clothes and €100,000 to show the world the beauty of mathematics. The result, shot in three days, is the 26-minute-long erotic film Rites of Love and Math, which premieres this week in Paris.] 4 comments|post comment

pics plz [09 Apr 2010|07:13am] math_fridge x-posted a few places Greetings! I was wondering if a picture of Stephen Semmes (living legend/analysis professor at Rice University) existed anywhere on the Internet, or (long shot) if anyone has a picture of him and has heard him say "I don't mind if people with pictures of me distribute them." This is for a programming assignment for a class - I would like to make an animation about him. However, Google Image Search is turning up nothing and the Rice website doesn't seem to have a picture of him. If you don't have a picture, or have a private picture I can't use, it would also be very very useful if you could tell me what he looks like so I can try and draw him. Thank you! post comment

Graduate Schools?

What I don't know that I don't know [09 Dec 2009|02:10am] pgadey Hello, I'm at a small liberal arts university studying mathematics. I'm particularly drawn to algebra. Group theory and its (co)homology seem interesting to me. The problem I'm faced with though, is that there are only two other people in my groups class, and one was the professor. The exact same thing happened in my rings class, my galois theory class was just me and the professor. I have no friends to talk to in person about anything mathematically interesting. I'm feeling like my exposure to this stuff is really limited. When I go to the undergrad math conferences I really enjoy the atmosphere and the opportunity to discuss interesting problems. I've done a little bit of graduate algebraic topology, at a summer school, which was nice - again the company of like minded individuals was very welcome. Did anyone have a similar undergrad experience? Have they since evaporated? How can I tell if I know anything about anything or where my education stands relative to other Canadian undergrad programs? 6 comments|post comment

Math Blogging? [27 Nov 2009|09:43pm] pgadey Hello! I'm looking for a nice way to blog the math content and photos I'll be taking next term. From what I understand Wordpress seems like a pretty good way to do this. Does anyone have recommendations for how to go about doing this? Any personal experience out there? I'm looking for hopefully free stuff. 5 comments|post comment
