Math is sometimes called the science of patterns.

Math is sometimes called the science of patterns.

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'.

Some people think that mathematics is a serious business that must always be cold and dry; but we think mathematics is fun, and we aren't ashamed to admit the fact. Why should a strict boundary line be drawn between work and play? Concrete mathematics is full of appealing patterns; the manipulations are not always easy, but the answers can be astonishingly attractive.

Juggling is sometimes called the art of controlling patterns, controlling patterns in time and space.

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.

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