I bought this book because I am hoping to write a book myself, giving a thumbnail sketch of history relevant to today's climate science (including Global Warming) from the Ancient Egyptians through Newton and Foucault and into the present. Real meteorology started 7 years after Foucault's work, as a direct result of what was learned from Foucault's pendulum.
I am a climate scientist, not an historian, so I have a steep learning curve to write such a book.I had previously obtained Toomer's magnificent translation of Ptolemy's "Almagest" (it shows Ptolemy to have been the world's first full-on theoretical physicist, and a magnificent teacher). I knew Toomer valued Gingerich highly, so I bought Gingerich's book. It has not disappointed. It has helped me to understand Ptolemy's fairly opaque book much better, and has also given me a much better appreciation of Copernicus the man.
I would have liked it if Gingerich had described Brahe in the same way -- we scientists value observations first, then theory -- and Ivar Peterson's "Newton's Clock" does a better job on Kepler. Nevertheless, I nearly gave this book five stars, not four.
