Recently a friend asked for assistance with an E&M problem. After dusting off that part of my brain and helping him out, it occurred to me that I used to really enjoy working out problems like that. And it used to be easier too! So I resolved to start working some physics math problems from time to time, for fun mental exercise. Since I also have a LaTeX fetish, I thought it would be even better to typeset nice solutions. The result:
http://bigreddot.wordpress.com/ So, on the chance that there's anyone else so inclined to comment or discuss mathy physicsy problems, or discuss the (sad) state of online math typesetting, or suggest interesting problems to work through, or even contribute... well, check it out. :)
NB: I had wanted to do this little project here on LJ, but evidently adding LaTeX support has already been proposed by users and subsequently rejected outright by LJ staff. Wordpress supports LaTeX out of the box, so that's what I chose.
