What are some interesting facts about von Neumann, known as the father of computers?

? John von Neumann (1903~1957), one of the most important mathematicians of the 20th century, has made outstanding achievements in many fields such as modern computers, game theory, nuclear weapons, and biological and chemical weapons. He is one of the greatest scientific all-rounders and is known as the "Father of Computers" and "The Father of Game Theory" by later generations.

? Originally from Hungary. PhD in Mathematics from the University of Budapest. He taught at the University of Berlin and the University of Hamburg. He went to the United States in 1930 and later became an American citizen. He has served as a professor at Princeton University and the Institute for Advanced Study in Princeton, and a member of the U.S. Atomic Energy Commission. Member of the National Academy of Sciences. He was famous for his early research on operator theory, oscillation theory, quantum theory, set theory, etc., and pioneered von Neumann algebra. During World War II, he contributed to the development of the first atomic bomb. It provides a basic solution for the development of electronic digital computers. In 1944, he co-authored "Game Theory and Economic Behavior" with Oskar Morgenstern, which is a foundational work in the discipline of game theory. In his later years, he studied the theory of automata and wrote the book "Computer and Human Brain", which accurately analyzed the human brain and computer systems.

Von Neumann's performance. Von Neumann once encountered someone asking him a question that is probably familiar to Chinese primary school students. It is like two people walking towards each other, with a dog running back and forth in the middle, and asking how far the dog has moved since the two people met. The time of encounter should be found first, and then multiplied by the dog's speed. If I remember correctly, when I was a child, I heard that Mr. Su Buqing was asked this question on a bus in Germany. Of course, he would not feel any difficulty. Von Neumann also gave the answer instantly. The person who asked the question was very disappointed and said that you must have heard of this trick before. He was referring to the above method. von Neumann said: "What's the trick? All I did was count every time the dog ran, and then calculate the infinite series..."

Banach (Banach, Polish genius Mathematician) attended a mathematics party in 1927. He and many mathematicians poured Neumann with vodka. Eventually, Neumann was so drunk that he went to the toilet and probably vomited. But Bananch recalled that when he came back to continue discussing mathematics, there was no interruption in his train of thought.

In 1944, von Neumann participated in the design meeting of the first electronic computer, EDVAC. There were many experts involved in the design of ENIAC at the meeting. Everyone was discussing the design plan and felt that the problem was very difficult to solve. "KAO, look!" So von Neumann drew a picture, and then began to write eloquently about the creation of the computer world - The First Draft Report on the EDVAC, von Neumann This is how Iman Structure was born.

Once, von Neumann was at a party, and the hostess bravely asked him a riddle: Two trains were running opposite each other on the same track at a speed of 30 miles per hour, and were 1 mile apart. , then a fly perched in front of one train flew towards the other train at 60 miles per hour. When it flew to the other train, it quickly flew back. It kept flying back and forth. , until the two trains inevitably collide. Ask how many miles the fly flew? Most people, especially those who know a little math, first calculate the distance it flies back and forth, and then add These results? Add up. This involves the problem of summing an infinite series. It is not difficult to do, but it is troublesome and time-consuming. In fact, there is a trick here. First, calculate how long it will take for the two trains to collide. It is easy to calculate that it is 1 minute. And a fly flies 60 miles per hour, which is 1 mile per minute. It is too easy. Almost as soon as the hostess finished explaining the question, von Neumann answered: "1 mile." " I'm so surprised you figured it out so quickly," she said. "Most mathematicians don't see the trick and instead use infinite series to calculate it, which takes them a long time." "What technique? I also calculated using infinite series," von Neumann replied.
