The Equation of God is a fascinating story about the search for the most important physical theory that can explain the birth of the universe, its fate and our place in it. The famous physicist and popularizer of science Michio Kaku traces the whole path of amazing discoveries - from the Newtonian Revolution and the foundations of the theory of electromagnetism, laid down by Faraday and Maxwell, to Einstein's theory of relativity, quantum mechanics and modern string theory - leading to that great theory that could combine all physical interactions and give a complete picture of the world. For more than half a century, physicists from different countries have not been able to achieve this grandiose goal. Have they chosen the right path? Is there a "light at the end of the tunnel"? This is what Michio Kaku reflects on.
