Copernicus, a great astronomer, heard in middle school that time can be determined by the shadow of the sun. The name of this instrument is sundial. Curious, he asked the teacher about the principle of the sundial, went home and found some waste materials, which were quickly made. He used sundials to study the laws of motion of the sun and the earth. When Copernicus grew up, he put forward the famous "theory of the sun rising", which overthrew the wrong statement that the sun goes around the earth.

Lomonosov, a great chemist, was born in a fisherman's family and went fishing with his father since childhood. He is interested in all natural phenomena that occur in the ocean.

Edison was interested in everything when he was a child. I always want to try something I don't know and find it. Once, he saw a wild beehive near the fence of the garden. He felt very strange, so he poked it with a stick to find out. As a result, his face was swollen by a wild bee sting, but he still didn't want to see the structure of the hive clearly. Edison later became a world-famous great inventor.

Li Siguang, a great geologist in our country, used to lean on some stones of unknown origin in his hometown when he was a child and asked himself curiously, why did these lonely boulders appear here? By what power did they come here? Later, Li Siguang traveled all over the mountains and rivers in China, and did a lot of investigation and research. Finally, he came to the conclusion that these strange stones are pumice of glaciers and the remains of Quaternary glaciers. Corrected the wrong theory of foreign scholars that there is no Quaternary glacier in China.

Newton, a great physicist, was curious when he saw the apples ripe when he was a child. He thought, why does everything on the earth fall to the ground after losing its support, but not in other directions? Later, he finally discovered the law of gravity.
