I can't believe this book is out of print. Didn't the Astronomical Society of the Pacific carry it?
It succeeds at its unique role: a travel guide for the scientifically inclined. It notes the problem that one can easily walk right by places of great importance in the history of science that are in the immediate vicinity of places everyone knows, for lack of a handy guide to where they are. One example of this is the old Cavendish lab in Cambridge, the nursery of the atomic age and where the genetic code was deciphered. It's barely 100 m from Kings College, the most popular tourist spot in the city. Another is the plaque at Oxford commemorating where Robert Boyle did experiments with his air pump, built by Robert Hooke, who built a microscope and discovered living cells. It's just down the street from All Souls College. Another is the apartment in Bern in which Einstein lived when he was a patent clerk in 1905, in which he wrote four papers that revolutionized physics (the photoelectric effect, special relativity, E=mc2, and Brownian motion). I'm ashamed to admit having walked right by it in 1972, because I didn't know it was there, and this book didn't exist. Next time, I won't miss it!
This book is also a pleasant read, not bad for first-class history of science. The organization is unusual, being geographical, but then, it is a travel guide. Still, the history is thorough and well written.
