Someone has said that all the great jugglers are dead.

A lot of the high-level sports are really in your mind.

Someone has remarked that 'An ideal math talk should have one proof and one joke and they should not be the same'.

I was reminded of the Sydney Harris cartoon that said 'adding two numbers that have not been added before does not constitute a mathematical breakthrough'.

It wouild be very discouraging if somewhere down the line you could ask a computer if the Riemann hypothesis is correct and it said, 'Yes, it is true, but you won't be able to understand the proof.' John Horgan.

Well, as you know, there are 24 hours in every day. And if that's not enough, you've always got the nights!

AB=1/4((A+B)^2-(A-B)^2) is an amazing identity, and unfortunately, I have to remind my current students how to prove it.
