Yesterday was Pi Day (3/14). To celebtrate, I ate some slices of pizza pie. Also, here is an explanation of how to figure out the area of a circle much as the ancient Greeks did. You'll notice that the principle is the same that's used in Calculus to measure the area under a curve. In fact, the Greeks used the same general method to calculate all sorts of areas and volumes. Of course it would be about a couple millenia before the invention of the Calculus where we could calculate the area under any defined curve.
Yesterday was also Albert Einstein's birthday. Here's an audio recording of the man himself explaining the significance of his most famous equation.
And finally, just for fun, here's what you get when you cross Gilbert & Sullivan with Ray Kurzweil. Enjoy.
