The Pythagorean Theorem is unquestionably the most well-known mathematical theorem. Eli Maor tells the entire tale of this well-known geometric theorem in this book. Maor demonstrates that the Babylonians were aware of the theorem more than a thousand years before Pythagoras, despite the theorem being credited to him. Pythagoras might have been the first to demonstrate it, but we no longer have access to his evidence, assuming he ever had one. However, the theorem is crucial to practically every field of science, whether pure or applied. Maor vividly depicts many of the individuals who contributed to the formulation of the Pythagorean theorem, offering a fascinating context for what is arguably our oldest and most enduring mathematical achievement.
