“The true sign of intelligence is not knowledge, but imagination.” – Albert Einstein
Today is a day Einstein would have enjoyed. It’s National Pi Day, named for the mathematical constant that’s the ratio of the distance around a circle to the circle’s diameter. This produces a number, and that number is always 3.141592653 . . . continuing without end but always the same numbers. It's quite helpful in solving problems or making discoveries.
Celebrating National Pi Day on 3-14 makes sense because the first three numbers are, of course, 3-14. I think Einstein would especially like National Pi Day (something that wasn’t celebrated while he was still alive) because it also falls on his birthday. Einstein (born in 1879) probably would have had as much fun with that as anyone because he often showed that he had a great sense of humor to go along with his brainy abilities.
He once noted that people should never kiss and drive at the same time. Because, he added, then you aren't giving the kiss the proper amount of attention. He also said – probably with a bit too much modesty – that he didn’t keep a notebook of his great ideas because “I’ve only ever had one."
A final note from Einstein: “Learn from yesterday, live for today, and hope for tomorrow. The important thing is not to stop questioning.”
