Did Sir Isaac Newton write any books? His best known book is Principia (Philosophiae Naturalis Principia Mathematica) published in 1687; which includes his laws of motion. Edit
Answered by The Community. Making the world better, one answer at a time. Though Newton claimed to be self-taught, it is predicted that he was taught by Robert Hooke. It is also thought that after Hooke's death, Newton stole some of his ideas and claimed them as his own. After Hooke's death, a great number of his published works went missing from a library very few had access to and Newton was one of those selected individuals.
