from Clifford Pickover

When I was a mathematics teacher, I enjoyed reading Clifford Pickover's books. Really gets at showing the beauty of mathematics through patterns. I subscribe to his tweets on Twitter. Here are some:

•  "Dammit I'm Mad" spelled backwards is "Dammit I'm Mad." A palindrome!

• Leaving a tip:

• Mother's Day this year, May 12, 2013, is a Pythagorean Triple:  5^2 + 12^2 = 13^2

• Fibonacci Cabinet:

• Consider a pizza with radius z and thickness a. Then, its volume is "pizza" (or pi*z*z*a)
