A response to Rachel’s comment, which made me laugh out loud, is warranted as a full-on blog entry.
I did not know all that info about 28! And since yes, I am turning 28, this is exciting to know! I’d never even heard of this perfect number phenomenon before. I’d intended to be a physics-math double major in college, but dropped the math pretty darn quickly (after linear algebra, which kicked my ass second semester of freshman year).
I am a big fan of prime numbers, though, and will be psyched for 29. I once went to a talk by a friend on happy numbers; that was something I’d never heard of before the talk. Turns out 28 is also a happy number! Boy next year is going to be good :)
