Kean talks about fruit flies, Watson and Crick, cloning, Darwin, birth defects, Mendel, the Human Genome Project, Paganini, Thomas Jefferson's descendents, and much more. a lot of topics to cover in 350 pages plus endnotes (read them, they're funny). Kean's a good writer and turns these various topics into a compelling story, a great narrative of science

I recommend it, especially if you read and enjoyed The Disappearing Spoon or anything by Mary Roach. a 6.
