Synopsis

"Equations without Solutions" builds mathematics from the bottom, faithfully reproduces the structure of modern mathematics, and shows the process of human rational search. Taking the search for the root formula of a quintic equation as an example, it provides a complete process of dismantling the problem, clearly defining it, analyzing abstraction, deductive reasoning, and obtaining the answer. "The Unsolvable Equation" is narrated from a first-person perspective, which is natural and vivid. However, unlike ordinary popular science books, this book does not give up or lose a trace of the integrity and rigor of modern mathematics. In addition, the whole book has a large vertical span, from the lowest level of formal systems to the highest level of Galois theory, and will present readers with many development contexts of philosophy and mathematics. "The Unsolvable Equation" is aimed at people with junior high school education and above, and aims to popularize and inspire the spirit of rationality, speculation, and exploration.

Reader comments

The writing is very good, but there is a little display problem in Chapter 4. Several expressions cannot be displayed. I bought all the books. If there are any problems, I took pictures of the correct content and commented them in the corresponding positions. If there are still display problems, you can leave me a comment and I can help you take pictures.

This book is very interesting. It explains mathematical knowledge in the form of a story, so that even a math idiot like me can understand it. The stories in the book reminded me of the problems I encountered in life. Many times we need to be like mathematicians and keep trying to find the answer. I like this kind of enlightening reading and recommend it to everyone!

Save money: I really want to learn how to find this textbook by myself. Only the beginning of this book is popular, and the theorems start to be explained later ()

Having just finished the quantum exam, I was forced to review group theory again. It was great.

Define essence with properties, and then prove many properties in turn

Please Let the Male Protagonist Only Do School Stories About Studying and Participating in Competitions! No Heroine!

Really, a good campus novel would force multiple people to be ambiguous, and only want the protagonist to focus on studying, so it should be pure. There are so few books like this! !
