" On Gravity offers a new and refreshing base from which to delve deeper than most popular-science books into the most pressing problems in fundamental physics."-Benjamin Skuse, Physics World Gravity may be absurdly weak, but that doesn’t mean it’s easy to fully understand, or overcome."-Jeff Foust, Space Review or those who want to move beyond popular books about gravity, but aren’t ready for a massive textbook with advanced mathematics, On Gravity does provide more insights about how gravity works without getting too complex. "With On Gravity, Zee decides to shoot for a middle ground in terms of level of sophistication. It’s a tour intended to take the reader a step beyond a popular treatment and give a deeper glimpse of the beautiful and uncompromising structure underlying the theory."-Tara Shears, Times Higher Education by the end of the book, you will be breathless, but up to date with the latest advances in the science. For anybody with a desire to understand what is happening at the forefront of our exploration of the universe, this is a perfect start."- Mathemafrica " is exactly what is needed to communicate to the general public the beauty and depth of Einstein’s theory of gravity. begins its tour of Einstein’s general theory of relativity with the discovery of gravitational waves, and lands the reader deep in the mysteries of dark matter and energy."-Liz Else and Simon Ings, New Scientist
"If you already know a bit about the topic, and are not afraid of a few equations, On Gravity will take you deeper (if you are very brave, the appendix will even explain the meaning of curved space-time)."-John Gribbin, Wall Street Journal Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy.Ĭoncise and precise, and infused with Zee’s signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Inspired by Einstein’s audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein’s general theory of relativity. From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. Of the four fundamental forces of nature, gravity might be the least understood and yet the one with which we are most intimate.
