In this book, mathematician Jordan Ellenberg, author of "Devil's Mathematics", leads us on a journey of exploration into the vast sea and sky. The ultimate meaning of the journey is: by discovering the power of geometry, we can better think about every real-life problem and re-understand the world around us. How many holes does a straw have? What is the winning way to play the game Nim? How are the public and private keys generated in digital currency transactions? What can we do to stop a pandemic from ravaging the world? Why is artificial intelligence so good at learning to play chess but not at learning to read sentences? Can the ancient Greek golden ratio be used to predict stock market trends? If your children really want to learn how to think, what should they learn in school? It is true that all these problems are related to geometry. For most people, geometry is a course full of boring and stereotyped exercises. Once you graduate from high school, it is thrown into the "old paper pile" together with your braces and the pop songs you once followed. When you think of geometry, if the first thing that comes to your mind is how to prove some obvious property about triangles through a series of steps, then this is not geometry, but only a very small part of geometry. To use an analogy, a triangle is to geometry what a verb is to a great novel. This book reveals the geometric principles behind some important issues in science, politics, economics, philosophy, medicine, information technology, biology, etc., Which we cannot turn a blind eye to in our work and life. The original meaning of the word "geometry" is "measuring the world", but after a long development process, its meaning is all-encompassing and can explain the operation mechanism of everything in the world. We live in a thriving, thriving "geometric city." Geometry does not transcend time and space; it is all around us, intertwined with all kinds of reasoning in our daily lives. Open this book and you will be amazed at the great power of geometry without putting it down.
Reader comments
The author's writing style is also very humorous, making boring geometry much more interesting. The examples in the book were very vivid and made me understand them all at once. I think this book is not only suitable for people who are interested in geometry, but also for people who want to understand the principles behind various phenomena in life.
It is a very interesting book. The mathematical terms in it provide me with a lot of information. I am more and more interested in the combination of mathematics and philosophy.
