Reading
Here are some books I have enjoyed tremendously. They all have to do with the development of revolutionary scientific ideas and the interesting characters that figured them out.
Five Equations That Changed the World: The Power and Poetry of Mathematics, Michael Guillen
Parallax: The Race to measure the Cosmos, Alan Hirshfeld
Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time, Dava Sobel
Genius: The Life and Science of Richard Feynman, James Gleick (or anything about Richard Feynman)
