“God’s Equation” is an exciting account of the search for the most important physical theory—the one capable of explaining the birth of the Universe, its fate, and our place within it. Famous physicist and science communicator Michio Kaku traces the entire path of astonishing discoveries—from the Newtonian revolution and the foundations of the theory of electromagnetism laid by Faraday and Maxwell, to Einstein’s relativity, quantum mechanics, and the modern theory of strings—leading to that grand theory that could unite all physical interactions and give a complete picture of the world. For more than half a century, physicists from different countries have been unable to achieve this enormous goal. Did they choose the right path? Is there “light at the end of the tunnel”? Michio Kaku reflects on this as well.
