The Equation-of-Time denotes the variance between Mean Time as told by the Stars and Solar Time as told by the Sun. It was initially identified by Ptolemy around 200 CE. During the Early Middle Ages, astronomers utilized this Equation to assist in lunar observations. Throughout the High & Late Middle Ages, sundials held prominence as the primary means of timekeeping, indicating Solar Time. However, in the 17th century CE, the emergence of precise pendulum clocks and watches prompted a gradual shift towards the adoption of Mean Time over Solar Time. In particular, the use of Solar Time corrected by the Equation-of-Time to determine local mean time, was used in the determination of longitude at sea. Prior to the availability of time signals, sundials - together with tables detailing the Equation - were used to set clocks.

#1 NEW YORK TIMES BESTSELLER • The epic story of the greatest quest in all of science—the holy grail of physics that would explain the creation of the universe—from renowned theoretical physicist and author of The Future of the Mind and The Future of Humanity When Newton discovered the law of gravity, he unified the rules governing the heavens and the Earth. Since then, physicists have been placing new forces into ever-grander theories. But perhaps the ultimate challenge is achieving a monumental synthesis of the two remaining theories—relativity and the quantum theory. This would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science: What happened before the Big Bang? What lies on the other side of a black hole? Are there other universes and dimensions? Is time travel possible? Why are we here? Kaku also explains the intense controversy swirling around this theory, with Nobel laureates taking opposite sides on this vital question. It is a captivating, gripping story; what’s at stake is nothing less than our conception of the universe. Written with Kaku’s trademark enthusiasm and clarity, this epic and engaging journey is the story of The God Equation.
