Happy Birthday, Einstein (Part 4)
Albert Einstein’s birthday was a couple of weeks ago, but today we have a belated celebration. MinutePhysics has finally finished its series on Einstein’s “wonder year” discoveries of 1905. In the last video, we began learning about the Special Theory of Relativity. This time, we find out how that theory leads to the most famous equation in the world…

What I’m Reading: Fermat’s Enigma
Homeschooling is much more than just doing school at home — it’s a lifelong lifestyle of learning. And thanks to the modern miracle of inter-library loan, even those of us who live in the middle of nowhere can get just about any book sent directly to our tiny home-town libraries.
As I mentioned in Math Teachers at Play 46, I’m trying to add more living books about math to our homeschool schedule, including my own self-education reading. So, a copy of Fermat’s Enigma: The Epic Quest to Solve the World’s Greatest Mathematical Problem finally showed up at my library, and I am thoroughly enjoying it.
Leap Years and the Number 29
Astronomer Dr Meghan Gray explains how messed up our calendar is. The mis-match between the length of a day and the time it takes the earth to travel around the sun makes a leap year necessary. From Numberphile.
Fibonacci Numbers and Plants
Have you ever wondered why so many plants grow in Fibonacci Numbers? Vi Hart offers a great explanation (with hands-on activities) in these three videos — and she introduces a new species called the slugcat, which my daughter thinks is adorable.
