Arthur Benjamin – Lightning calculation and other “Mathemagic”
Arthur Benjamin amazes with his uncanny ability to calculate. In a lively Ted Talk, Benjamin races a team of calculators to figure out 3-digit squares, solves another massive mental equation and guesses a few birthdays. How does he do it? He’ll tell you.
Arthur Benjamin – Teach Statistics Before Calculus, Ted Talk
Someone always asks the math teacher, “Am I going to use calculus in real life?” And for most of us, says Arthur Benjamin, the answer is no. He offers a bold proposal on how to make math education relevant in the digital age. The laws of nature are written in calculus but statistics and probability have more uses in everyday life.
Instead of our students learning about the techniques of calculus. I think it would be far more significant if all of them knew what two standard deviations from the mean, means and I mean it.
