Derivation of Newton’s Law of Gravitation [EPUB ebook] 

In Newton’s view, all objects exert a force that attracts other objects. That universal law of gravitation worked pretty well for predicting the motion of planets as well as objects on Earth and it’s still used, for example, when making the calculations for a rocket launch. But unfortunately it cannot be derived from first principles.
In this book gravity has been derived from first principles without any assumptions. What has been believed to be a fundamental force for years can actually be derived from first principles has this book explains. The derivation is simple and straight forward. The experiment to the derivation has also been proposed. This book will help us rethink Physics.
