In the last few places, the creators are all gods. Euler is the most prolific mathematician in history, and also a scholar who has written the most books in various fields (including mathematics and mechanics, optics, acoustics, water conservancy, astronomy, chemistry, medicine and so on). ). In the history of mathematics,18th century is called "Euler era". Born in Switzerland, Euler was blind in his right eye at the age of 3/kloc-0 and at the age of 59, but he was optimistic, with amazing memory and concentration. He was humble all his life and seldom named what he found with his own name. However, one of the most important constants -e is named.
There used to be a joke about e: in a mental hospital, a patient said to others all day, "I divide you, I divide you." I don't know why, these patients all have simple calculus concepts. They always think that one day they will be differentiated into zero and disappear like ordinary polynomial functions, so they avoid him. One day, however, he met an unmoved person. He was surprised. This person simply said to him, "I am the x power of E."
The genius of this formula is that it has no redundant content. Put the most basic E, I and pie in the same formula, add 0 and 1 at the same time, which is also the most important in mathematics and philosophy, and then connect them with a simple plus sign.
Gauss once said: "A person can't become a mathematician when he first sees this formula and doesn't feel its charm."
