The Theory of Relativity

The other day Liam was crawling around and he crawled his way over to Daddy's bookshelf.  He examined the books on the bottom shelf before carefully choosing one that interested him: Exploring Black Holes: Introduction to General Relativity.  I laughed at the odds of him choosing THAT book, and placed it back on the shelf.  A few minutes later, I look over and see him with THE SAME BOOK!!  And later that night, after Daddy got home, he chose that book AGAIN!

He's one smart cookie.
