“If you look back on history, you get the sense that scientific discoveries used to be easy. Galileo rolled objects down slopes. Robert Hooke played with a spring to learn about elasticity … Today, if you want to make a discovery in physics, it helps to be part of a 10,000-member team that runs a multibillion dollar atom smasher. It takes ever more money, more effort, and more people to find out new things.” Why is this?
