It’s Random Thursday time again, even though the little map on my stats page suggests that most of you probably won’t be reading this until Friday, what with all the cooking and carbo-loading and the tryptophan overdosing and dishwashing and so forth.
But that’s okay, since this post isn’t going to be all that random, either.
Jane, my ten-year old, who is addicted to the Youtube offerings of mathemusician Vihart,* showed me this video a couple of days ago:
“That’s perfect!” I said. “Does she have any side dishes?”
“Sure,” she said, clicking. “There’s Mathed Potatoes . . . ”
” . . . Or a Green Bean Matherole.”
“Wow,” I said. “Let me guess–Pi for dessert?”
“Well . . . Yeah, but that one gets really complicated. I want tau, instead.”
“What’s tau?” I asked, having passed trig by the grace of an extremely generous bell curve.
She grinned. “TWO pi.”
