So I'm walking down the driveway at Andy's house in Michigan and see this written in chalk. Something like the following conversation takes place:
Me: What's that?
Andy: Oh, c'mon. You know.
Me: Sorry, never laid eyes on it.
Andy: It's Euler's equation, the most beautiful equation in math.
One mathematician said it is "like a Shakespearean sonnet that captures the very essence of love, or a painting that brings out the beauty of the human form that is far more than just skin deep, Euler's equation reaches down into the very depths of existence".
And another stated that the identity "is absolutely paradoxical; we cannot understand it, and we don't know what it means, but we have proved it, and therefore we know it must be the truth."
I totally don't get it. Nice to know that in some ways my kid is smarter than the old man.
