If the writer declares that Pythagoras solved Einstein's relativity theory, you might retort like this.
"Are you kidding me? The theory of relativity is difficult even for college students majoring in physics. How dare you say that the mystic philosopher Pythagoras was able to solve modern physics theory 2450 years ago?"
Yes, you can say that because you haven't read this book yet. But please read the first part of this book at least. Then, with only Pythagorean theorem, Einstein's theory of relativity can be understood visually and sensibly. If you read this book to the end, you will be able to easily derive the important formulas of the relativity. To this writer's opinion, you would respond as follows.
"Perhaps such a view is nothing more than an exaggeration of Pythagorean theorem, which is applied to the theory of relativity a little."
Yes. you are right. There was such a point in the past explanations of the theory of relativity. However, the Pythagorean theorem in this book is much different from the past views. The theory of relativity is concisely illustrated in a geometrical way and the right angled triangles show the principle of relativity theorem visually in a circle. Further, its physical meaning goes deep into philosophical thinking, and you can derive several important formulas of special relativity from a right angled (the Lorentz transformation, E=mc², the law of momentum conservation of the space-time in the special relativity and so on) When you get to that level, you will realize how wonderful principle is the Pythagorean theorem.

She studied public administration and literature during her school days. She hated physics and mathematics, but her interest in ancient Greek natural philosophy led her to modern physics. In order to understand the natural philosophy in depth, she had to study the physics a little. Her studies on physics , which was not for her grades but for her philosophy, gave her pleasure. In this studying process, the Pythagorean theorem became a great guide for her to understand the 4-dimensional space-time of the relativity. The book, 'Einstein's theory of relativity solved by Geometry', contains all the processes of her studying the theory of relativity from a geometric point of view. Therefore, this book would be a good guide for those who are burdened with difficult mathematical approaches.
