Recent Math/Science Triumphs Include

Hi, reader. I wrote this in 2007 and it's now more than five years old. So it may be very out of date; the world, and I, have changed a lot since I wrote it! I'm keeping this up for historical archive purposes, but the me of today may 100% disagree with what I said then. I rarely edit posts after publishing them, but if I do, I usually leave a note in italics to mark the edit and the reason. If this post is particularly offensive or breaches someone's privacy, please contact me.

Finally getting to recursion in How to Design Programs, just after doing a 3-D distance calculation and discovering that my Pythagorean theorem intuition still held (the distance from zero in exercise 9.1.3 is the square root of the sum of x squared, y squared, and z squared). Now to do Return On Investment calculations, which involve much more guesswork.
