Gravity’s Century: From Einstein’s Eclipse to Images of Black Holes

Ron Cowen offers a sweeping account of the century of experimentation that has consistently confirmed Einstein’s general theory of relativity. He shows how we got from Eddington’s pivotal observations of the 1919 eclipse to the Event Horizon Telescope, aimed at starlight wrapping around the black hole at our galaxy’s center.

Review :
Cowen is a gifted science writer and storyteller, and the story is amazing! -- John C. Mather, winner of the Nobel Prize in Physics [Cowen's] brisk, engaging narrative leads us from Einstein's famous 'thought experiments' through theorists' many (so far unsuccessful) attempts to marry quantum mechanics with general relativity, and up to recent (more successful) efforts to observe gravitational waves and black holes. -- Wall Street Journal There are some extremely clever ways to visualize how gravitation works in a Universe governed by General Relativity under a wide variety of physical conditions, and Cowen explores many of the classic ways you've probably seen before along with some incredibly creative ones that were new, even to me. -- Ethan Siegel Forbes A brief, accessible account of the 1919 eclipse and subsequent advances in cosmology, touching upon dark matter, dark energy, quantum gravity, and black holes. It's a very quick and readable introduction to some of the exotic findings that came in Einstein's wake. -- Bookforum This is as good a short introduction to Einstein's thought as one could wish for. -- Simon Ings The Spectator In a conversational style, the veteran physics writer chronicles the field's greatest hits in the century since a solar eclipse proved Einstein was right. -- Gemma Tarlach Discover A breezy and enjoyable read, a welcome addition to a crowded shelf of books on these topics. -- Peter Coles Nature Gravity's Century is remarkably easy to follow and read. If you are a keen beginner, or just interested in some of the people behind the science, read this book. -- Laura Nuttall BBC Sky at Night This gracefully written history of 20th-century gravity research from science writer Cowen shines a light on a key aspect of modern physics...Filled with vivid descriptions of cutting-edge work and the scientists behind it, Cowen's book is fascinating, both a learning experience and a pleasure to read. -- Publishers Weekly (starred review) A clear and compelling narrative about the development of our understanding of gravity and the universe, powered by Einstein and his cohorts. Cowen weaves together the historical and personal events leading to this revolution and brings us up to date with the ideas and speculations that will likely forge an even newer and more radical understanding of the nature of the world. -- George F. Smoot, winner of the Nobel Prize in Physics Einstein's general theory of relativity radically changed our notions of space, gravity, and time. Gravity's Century takes us from Einstein's struggle to develop his theory up to the modern day--when the detection of gravitational waves from black holes has confirmed general relativity's most audacious claims, even as scientists are still trying to reconcile the theory with the other great idea of twentieth-century physics, quantum mechanics. -- David Spergel, Princeton University Accessible and compact...A great introduction to Einstein's theory of general relativity and the century of research that has been testing his ideas since. -- Leon Vlieger Inquisitive Biologist A concise chronicle of the dramatic expansion of our knowledge of the universe, from the eclipse expeditions of 1919 to test Einstein's theory of relativity, to the Event Horizon Telescope's black hole images of 2019. -- Mike Perricone Symmetry Clear and readily intelligible to the non-specialist. -- Johannes E. Riutta Well-Read Naturalist Its informal, readable style hides an enormous amount of physics and a fair share of history. -- Choice [An] enjoyable read...Cowen does a good job of breaking down ideas so that they are easily understood...I would recommend Gravity's Century to anyone with an interest in astrophysics in general, or in gravitation in particular. -- Earl Patrick Bellinger Metascience
