Genius -- these days, we bandy the term about ever so freely. Everyone's a genius, including this 2-year-old wielding a pair of nail clippers. Then, Neil deGrasse Tyson comes along and reminds us what a genius really looks like. Asked "Who is the Greatest Physicist in History," he responds, Isaac Newton, without any hesitation. Newton discovered the laws of optics, proving that white light is actually made up of colors, the colors of the rainbow. He mapped out his three laws of motion and the universal laws of gravitation. And then he invented differential and integral calculus to explain why planets orbit in an elliptical fashion. Now get ready for the kicker. This all happened before Newtown turned 26. That, my friends, is what genius looks like.
