3. Supplementary stories:
The story about the falling apple
An accidental event can often trigger the flash of a scientist's thoughts. It was a warm evening in the late summer of 1666. In Ullsthorpe, Lincolnshire, England, a young man with a book under his arm walked into the garden of his mother's house, sat under a tree, and began to Died into reading his book. As he turned the pages, something shook in the branches above him. One of the most famous apples in history fell and hit 23-year-old Isaac Newton on the head. It happened that on that day, Newton was thinking hard about a question: What force keeps the moon in its orbit around the earth and the planets in their orbit around the sun? Why did the apple that hit him in the head... Falling to the ground? It was from thinking about this problem that he found the answer to these? The theory of universal gravitation.
Watt and the Steam Engine
Watt was a Scottish inventor. His most outstanding contribution was to make major reforms in the steam engine and invented the reciprocating steam engine. In honor of him, his name is used as the unit of power in physics. One night in his childhood, Watt was drinking tea at home. The boiling water had just been poured into the teapot and he could not drink it for a while. Watt waited patiently for the tea to cool down, opening and closing the teapot lid. When he put the lid on the teapot and accidentally blocked the spout with his fingers, the steam in the pot made the lid pop. The steam could actually lift the lid off the teapot. This phenomenon caught Watt's attention, and he continued to play with the teapot. The grandmother sitting aside thought that Little Watt was too boring, so she scolded him. But Watt was thinking about the power of steam and still playing with his teapot. This "accidental" discovery left a deep impression on Watt. In the future, Watt devoted himself to the research of steam engines with great interest, which cannot be said to have nothing to do with this "accidental" discovery.
4. Summary and encouragement:
The discoveries of Li Siguang, Newton, and Watt are inseparable from diligent use of the brain and good thinking. I hope that our children will be like these scientists, have strong curiosity, ask more questions and think more when encountering problems, and explore unremittingly to uncover magical mysteries one by one, and contribute to the country and mankind.
