On today’s date, September 18th, Leon Foucault was born. Well-noted for his demonstration of the Foucault Pendulum, which was conceived as a simple experiment to show the rotation of the Earth, Foucault also devised an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.
Happy 195th birthday, Monsieur Foucault!

Description: This week I made an animated chart of butterflies! These are all butterflies that you can find throughout North America, and I picked the 42 that I thought were the most colorful and unique.
