I can't read a computer screen and never use a calculator. It's all in my head and by hand.

I'm always crunching numbers, so my calculator watch is a must.

Calculation has its advantages, but no one likes naked calculation.

Nature doesn't feel compelled to stick to a mathematically precise algorithm; in fact, nature probably can't stick to an algorithm.

The first calculators tended to sell for $400 or $500. Today, you can get a pretty good one for 4 or $5.

I just love math and most people don't.

I always thought that I was okay with arithmetic.

I'm bad at math.

I'm not someone who calculates things.

Nature uses as little as possible of anything.
