From theand months each of us spent suspended in the womband anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. Inand On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity.and Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain howand gravityand 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.and 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.Concise and precise, and infused with Zee's signature warmth and freshness of style,and On Gravityand opens a unique pathway to comprehendingand relativityand and gaining deep insight into gravity, spacetime, and the workings of the universe.\u003c\/p\u003e","brand":"A.
