Brian Cox, entropy and sandcastles

The quote in my previous post mentioned the second law of thermodynamics. Though I had studied something about it in high school, I didn’t (and don’t!) remember anything about it. So I asked M. He is the scientist of the family after all. Well, he wasn’t very helpful! He remembered something about entropy, but not much more.

Good thing I found another Brain Pickings’ post with Brian Cox explaining entropy. Oh, Brian Cox!
