Math Poems

I posted a math poem two days ago. Here are a few more that I love (though I’m probably breaking some copyright laws by posting them… oh, well, math humor is meant to be shared):

Pi goes on and on and on,
and e is likewise cursed…
I wonder which is longer when the digits are reversed?

A mathematician confided,
A Mobius strip is one-sided.
You’ll get quite a laugh,
When you cut one in half,
For it stays in one piece when divided.
