Isaac Newton sat under an apple tree in the sweltering summer of 1666, and the 24-year-old was pondering as he scratched his nose. An apple slammed into the door of his head, and he immediately discovered gravity. This story is written in almost all textbooks.
Voltaire was the most intelligent and witty man in the world at that time, and it was such a story he made up in his own Biography of Newton. The philosopher said he had heard the story from Newton's niece, Catherine Barton Condiut, who had lived with Newton for more than 20 years.
However, It is true that Newton never recorded such a story, and he wrote many works in his lifetime, but he could not find such a story in his works and letters, and Newton did not talk about it to others.
A German astronomer named Karl Fredrich Gauss proposed perhaps the most plausible explanation for the origin of the Apple theory.
Gauss thinks so: "The story of the Apple is so absurd that whether the apple falls or not, how can one believe that there is such a discovery in such a way as to accelerate or slow down?" There is no doubt that this matter is just a similar statement. A stupid and obnoxious man came to Newton and asked him how he had made this great discovery, and Newton believed that this man was a fool and that Inbey wanted to get rid of him. He said that the apple had landed on his nose, and the man knew this very well and left contentedly. ”
