A lot of kids have personal “culture heroes” when they are growing up. I suppose athletes and celebrities predominate, maybe a political personage here and there. But I suspect lots of kids also have scientists or artists as personal heroes. My own culture hero when I was a youngster (Elementary School) was Albert Einstein (March 14, 1879 – April 18, 1955). I once sent him a birthday card and I had a scrapbook of clippings about him.
He still is one of my heroes. And today is his birthday. I’ll celebrate it with this nice little animation that explains the key concept in the Special Theory of Relativity, simultaneity. It’s short, accurate and understandable. So is the Special Theory. There are lots of books for the general reader if you are interested.
