Therefore, we should learn to think hard and not be lazy.

The proposition of "continental drift theory"
The famous "continental drift theory" was put forward by German geophysicist and meteorologist Wegener. On the map, he found that the protruding part of the eastern end of Brazil in South America on the west bank of the Great Sage is at right angles, which coincides with the concave part of the Cameroon coast in East Africa. Every convex and concave part of the Brazilian coast corresponds to almost every concave and convex part of the African coast. He mused: If two continents are moved so that they are close together, then the two parts will overlap.
Later, after a long-term study, he put forward the famous "continental drift theory" through geophysical, geological, paleontological and paleoclimatic arguments. He believes that the earth's continent was originally a whole, which began to split about 300 million years ago, moved to the east, west, north and south, and then became what it is now.
Later, new scientific discoveries further proved his theory.
Weiler's regret
Willer, a German chemist in the 0/9th century, was an accomplished scientist in science. He discovered two elements, aluminum and beryllium, but he also had regrets. On one occasion, when he was studying the ore, he found a chemical substance, and he arbitrarily concluded that it was chromium. Soon, the Swedish physicist and chemist Shaw Sturm also encountered this compound, but he didn't let it go easily.
Wheeler regretted it when he learned about it. Because of carelessness, he didn't think seriously and lost a good opportunity for scientific discovery.

Thinking is like digging a well. At first, it is muddy water. After a long time, people who are slightly aroused will come out. People's thinking is turbid at first, and it will be bright after a long time. Song Chenghao and Cheng Yi's "The Complete Book of Er Cheng, Henan Shicheng's Suicide Letter"
