Uncle Jacob supported him in studying physics and mathematics. When explaining the topic to him, he compared the operation of solving X in algebra to an interesting hunting. He said: "Mathematics is a very interesting science. When we are looking for beasts, we call them X, A, B and C. These known conditions are mountains, rivers and forests, and the beast X you want to hunt is hidden here. When we solve math problems, it's like looking around. Smart hunters will soon catch X. "

This metaphor is so interesting! Exploring the science of thinking gave Einstein great pleasure.

Einstein likes algebra and geometry. As soon as the textbook is issued, he can't wait to read it page by page, and he will do all the questions by himself first. He likes rigorous proof and reasoning best.

One day, Albert Einstein's big friend, Talme, a college student from Poland, gave him a gift-Geometry written by Euclid, an ancient Greek scholar. Einstein really couldn't put it down. For three weeks in a row, he did all the problems one after another. Some complicated questions, he also tried to find answers from many aspects.

There is a famous theorem, which is called Pythagorean Theorem in Europe and Pythagorean Theorem in China. The sum of squares of two right angles of a right triangle is equal to the square of the hypotenuse. Is this definitely the case? Do you know that some right-angled triangles are large in shape, some small in shape, some "fat" and some "thin", and the length of each side is different, and they all obey this theorem?

Talme asked, "Can you prove it yourself?"

"Yes!" Einstein scratched his fist's black hair and said firmly.

"If you can't prove it, you can read a book."

"I must prove it!"

Einstein spent several days writing and drawing on paper. He wants to prove this famous theorem himself. The book is nearby, and you will know the ready-made answer when you turn it over. But he made up his mind not to be lazy!

Finally, Einstein proved this theorem in his own way, but he was not satisfied. After repeated thinking, he also proved it in several other ways. The proof method is rigorous and novel, and you can tell at a glance that it is not copied from a book.

Talme looked at the neat answers on a piece of paper, looked at Einstein's tired face because of staying up late and lack of sleep, and thought that this child who worked so hard and was so smart would surely achieve extraordinary things in the future!
