It’s great! It’s simple, it’s elegant, its beautiful. It’s sort of like reading really beautiful poetry, that encapsulates the laws of mathematics. One of my favourite things about reading Euclid is that as you read you realize things that you’ve always sort-of known to be true, but never really thought of before, especially for somebody just getting into mathematics and who has never really thought about these things before.
