Wiener's father Leo is a strict father. His control and guidance of Wiener is very orderly and strict. He often flies into a rage over trifles, and casually curses such as "donkey", "idiot" and "beast". After 40 years, Weiner recalled the scene at that time and still had a lingering fear. However, Leo's control over Wiener is by no means unreasonable. He knows how to cultivate his son's excellent qualities. The supervision principle of combining leniency with severity has brought Wiener's intelligence into full play. When he was less than 7 years old, he had learned all the middle school mathematics textbooks from elementary mathematics to analytic geometry. I studied physics, chemistry, French, German and Latin. I have read books ranging from Darwin's theory of evolution to psychiatry, from Verne's science fiction to 18, 19 th century world literature masterpieces, and so on. Many people can't finish reading them all their lives. This is the source of his extraordinary wisdom as an adult. Apart from early education, Leo's decision to influence Wiener's life was to let his son's university attend Tufts College. This is a small polytechnic near Harvard. Why did you choose such a small college instead of studying at Harvard? Leo doesn't want Harvard's tense exams to destroy his son's healthy mentality, and he doesn't want a child who entered the university at the age of 1 1 to cause a sensation at Harvard. He wants his son to concentrate on his math. But math can't bind little Weiner's heart. His interests are constantly changing. Although this goes against Leo's original intention, it is indeed a small college with a relatively relaxed atmosphere arranged by his father, which has become a fertile ground for Wiener's original colorful knowledge structure and thinking advantages to further grow. After entering the university, Weiner's interest has never been stable. In the first year, he had a strong passion for physics and chemistry. He often sneaks into the laboratory to do chemical experiments or take electrical extracurricular adventures, and often conceives an experiment himself and tries to implement it. At this time, Weiner, who has not been self-deprecating, was praised by his classmates for changing from a mathematical prodigy to an engineering prodigy. He was very proud. Of course, because of his high starting point in mathematics, this specialized course is not a problem at all. In the second year, Wiener's interest shifted from engineering to philosophy. He was fascinated by Spinoza's precise views on ethics and Leibniz's versatility. He greedily read a large number of philosophical books and drew wisdom from them. Philosophy, the essence of human spirit, makes his little head richer, deeper and more dreamy. It is this profound philosophical foundation that enables him to deeply understand Russell's ideological background and enlighten his life. In the third year, his interest turned to biology. This time, it seems that he really got in. He decided to become a biologist. He often secretly followed biology students out to collect specimens, and gained the favor and trust of the old man who was the doorman in the biology laboratory, so that he could often sneak in and watch others do experiments. If he hadn't got into trouble later, his small stove might have been on until graduation. Once, he tried to do an anatomical experiment by himself. I invited two classmates, got a guinea pig from the kind janitor and sneaked into the laboratory for dissection. However, because they didn't run as fast as they thought, they looked worried. As a result, they not only forgot to use anesthetic, but also did not correctly separate the artery from the connected veins and nerves when ligating the artery. As a result, the poor guinea pig died painfully before the operation was completed. This is a catastrophe. Professor Jenkins from the biology department stormed in and flew into a rage. Because there, such inhuman vivisection is illegal, and it is likely to deprive the laboratory of the right to dissect. After this incident, Weiner was hit by many parties and had to take back his restless heart in mathematics. Until 18 years old, he obtained a doctorate from Harvard University with a paper on mathematical logic. After receiving his doctorate, Weiner went to Cambridge, England for further study. Here, he studied under his first teacher, the great philosopher and the great mathematician Russell. Getting rid of his father's direct control and the fresh academic atmosphere in Cambridge made Wiener refreshed and radiant. Russell's extraordinary bearing, intelligent mind, outstanding thoughts and elegant and fluent language expression fascinated Weiner. The first discussion and communication with first-class scholars made him feel solemn and sacred. But it didn't take long for Russell, who had keen insight, to discover that Wiener was not the kind of person who devoted himself to mathematics. So Russell taught him in accordance with his aptitude and enlightened him in philosophy. Inspired by Russell, Wiener turned scattered philosophical knowledge into a thinking tool and understood the significance of establishing interdisciplinary relations. The experience and lessons here are the earliest seeds for Wiener to finally choose interdisciplinary as his research direction. A year later, because Russell went out to give lectures, Weiner transferred to Hilbert's school at the University of G? ttingen in Germany. Hilbert is the greatest mathematical genius in human history. He is almost the only mathematician in the world who really understands all fields of modern mathematics. After coming to the University of G? ttingen, Wiener was shocked by Hilbert's profound thoughts, broad horizons and profound knowledge. Taking mathematics as a tool and technology to solve natural mysteries is different from taking mathematics as a pure formal system at that time, which influenced Wiener and made him finally unify physics, engineering, neurophysiology and other fields with mathematics. Only here did he really understand mathematics and fell in love with it. It turns out that mathematics is consistent with his kaleidoscopic fantasy world.
