Learn from history's greatest scientists. I read the biographies of scientists and tell you what I learned. The name draws inspiration from the brilliant mind of the mathematician Freeman Dyson who came up with the “Birds and Frogs” metaphor. In his world: Birds are thinkers who look at the big picture and survey the landscape from a great height. (Birds are theorists.) Frogs are thinkers who love playing around in the mud of specific problems, delighting in finding gems and then polishing them so that they become part of the superstructure that birds survey. (Frogs are experimentalists.)
