Even so, human beings have been crossing the river by feeling the stones for a long time, opening up territory with their bare hands, fighting against the hardness of this world with their bodies, living a hard life and making slow progress in civilization. It was 300 years ago that human beings used machines to produce against nature and entered modern civilization. It can be seen that the biological evolution on the earth and the development of human civilization did not go smoothly, but the snail crawled slowly for a long time and accumulated enough energy before it suddenly broke out and "collapsed" for thousands of miles.
The turning point of human civilization from primitive to modern is the industrial revolution (mainly in science and technology, of course). The birth of industrial revolution needs the guidance of theory, and the theoretical door for the rapid development of human civilization should be Newton's law of motion.
1687, Newton published an epoch-making masterpiece: Mathematical Principles of Natural Philosophy, which systematically put forward Newton's three laws of motion and the law of universal gravitation, ending the majestic and mysterious feeling that nature has brought to mankind for more than 2,000 years and providing mankind with the key to open the door of the world's knowledge treasure house. Since then, Pandora's box has been completely opened, and many disciplines such as mathematics, engineering mechanics and celestial mechanics have found the breakthrough point of the soul, showing a blowout development trend, directly pushing human society to an unprecedented historical revolution-the industrial revolution.
Newton, who made such a great contribution, is undoubtedly a giant of science and a promoter of human civilization. In return, Newton also enjoyed the treatment he deserved in the world: he was knighted as president of the Royal Society and buried in Westminster Abbey in London after his death. The funeral ceremony was noble and grand, and most members of the Royal Society attended.
However, even if Newton's contribution is well known to the world, as long as he is a human being, it is inevitable that "selfishness" will flood and cause gossip. For example, the famous physicist Einstein's contribution to Newton has always been sour.
Einstein once attributed Newton's law of motion to Galileo in "Talking about Galileo's Contribution" (there is a special space in the physics textbook of high school, but it can't be found now, and I am deeply impressed so far).
He believes that one of the reasons for the slow development of human scientific and technological civilization for thousands of years is that the relationship between movement and force is not clear. Although the problem seems simple, the deception of nature has blinded many philosophers: the car will move if it is pushed, and it will stop if it is not pushed. Therefore, Aristotle's view that "force is the reason to maintain the motion of objects" is almost unquestionable, but this fallacy has stopped human scientific and technological civilization for more than two thousand years.
More than 2000 years later, Galileo expressed doubts. He used the motion characteristics of the ball in the mountain to deduce the appropriate relationship between output and motion.
A canyon has two sides and a lowest point. When the ball is released from the highest point on one side, it runs down the hill at an accelerated speed, reaches the lowest point and continues to climb to the opposite side until it reaches the same highest point as before. If the opposite side is asymmetrical with the initial side, the ball will continue to run until it reaches the same height as the previous highest point.
This shows that the motive force of the ball moving in the ravine is to reach the same height as before.
If the opposite side is the same height as the lowest point, that is, the ball will go forward after reaching the lowest point, then the ball will run forward desperately in order to reach the same height as the highest point on the initial side. Because of the constant height, the ball will always keep moving in a straight line at a constant speed.
Take a look, force is not the reason to maintain the motion of an object, and the "straight line" motion attribute of an object has nothing to do with force. Galileo obtained the law of "straight line" motion of objects through his own observation and reasoning.
It's a pity that Galileo only put forward a conjecture and didn't rise to the level of "law", so Einstein said: The true meaning of motion summarized by Galileo was published as a law by an Englishman and was called Newton's first law.
Summarizing Einstein's words, it is not difficult to find that Einstein praised Galileo's contribution and used a lot of space to describe Galileo's description of the law of motion of objects. His meaning is also obvious: Galileo got the law of motion, not Newton, but Newton wrote the law summarized by Galileo in his own name. Is this "plagiarism"? Should I be "sour"
Therefore, even if Newton's first law successfully unveiled the mystery of nature, found out the relationship between motion and force that has plagued mankind for two thousand years, straightened out the perspective of human cognition of the world, opened the door of knowledge in the treasure house of nature, and promoted the rapid development of human civilization, Einstein thought that his law was actually summed up by Galileo and could not be counted on him, which would be "sour".
