I found a book

I was at a thrift store the other day, and, as is my custom when in any kind of thrift store or pawn shop, I checked out what books they had. This was one of those times that paid off.

I found, for a price of 2.5 USD, a copy of Euclid's Elements in excellent condition. It looked like it had just sat on someone's shelf untouched until they cleared out all their books. One of the most important things ever to be written in the history of humanity, for $2.50. I bought it, and then had a nerdgasm. You should all be jealous of me (unless you have a better copy of Elements, in which case, I am jealous of you).
