It's not often that you see a newspaper article about mathematicians but the Swiss embassy is doing stuff around Euler's 300th birthday. So, of course the Washington Post would notice ...
The statement in the article about a poll of mathematicians (math enthusiasts?) that named ei(pi) + 1 = 0 the "most beautiful equation" caught me by surprise.
I much prefer the more general form: ei theta = cos(theta) + i . sin(theta) because it neatly ties together geometry and calculus
So why is the simpler form considered so beautiful? Apparently because it contains five significant numbers: e, pi, i, 0 and 1 and three significant operations: addition, multiplication and exponentiation.
Looks like my view of beauty is closely tied to function. The majority of people polled seems to have plumped for sheer quantity.
