I. Franklin

1one day in June, 752, in the suburb of Philadelphia, USA, it was covered with dark clouds and thunder and lightning. On a wide lawn, two people, an old man and a young man, are flying kites with great interest. Suddenly, a flash of lightning cut through the clouds and drew a "Z" in the sky. Then there was a loud thunder and the rain poured down. The old man shouted, "William, stand in the straw house over there and tighten the kite string."

At this time, lightning flashed one after another, and the thunder was louder and louder. Suddenly William shouted, "Dad, look!" " "The old man looked in the direction pointed by his son, only to see that the original bare and taut hemp rope suddenly burst into anger, and those tiny fibers stood up straight. He shouted happily, "It's coming!" While telling his son to be careful, he slowly approached the copper key attached to the hemp rope with his hand.

Suddenly, as if he had been pushed, he fell to the ground and was numb. Without considering the pain, he got up from the ground and connected the Leyden bottle he had brought with him to the bronze key. There is electricity in this Leyden bottle, which releases electric sparks. It turns out that the sky electricity and the earth electricity are the same!

He and his son took the Leyden bottle home like a treasure.

The people who seized Sky Power were Franklin and his son William. Franklin was not only a great scientist, but also an outstanding politician and diplomat. He was one of the founders of the Declaration of Independence and the first American ambassador abroad.

Second, Archimedes

Archimedes was born into a noble family in Syracuse, and his father was an astronomer. Under the influence of his father, Asmid was fond of learning, thinking and arguing since childhood. When I grew up, I traveled across the ocean to study in Alexandria, Egypt. He learned philosophy, mathematics, astronomy, physics and other knowledge from Conon of Samos, a student of the famous scientist Euclid at that time, and finally learned from others and mastered the rich Greek cultural heritage.

During his study in Alexandria, he often walked along the Nile. In the season of long drought and no rain, he saw farmers laboriously pumping water from the Nile to irrigate the land, so he created a spiral water pump to take water from the river through spiral rotation, which saved farmers a lot of effort. Not only used today, but also the original prototype of all propellers used on water and in the air at present.

Third, Pavlov.

When I was a child, Pavlov and his brother dug a pit for planting apple trees. This hole has been dug. When my father saw it, he said it was misplaced and dug it again. My brother put down his shovel and quit, but Pavlov ignored the blood bubbles on his hand and dug again until he dug a hole and planted an apple tree.

Later, Pavlov became a physiologist, studying dog conditioned reflex in the laboratory all day.

He often uses his salary to buy experimental dogs. It takes four or five hours to dissect a dog. He counted the dog's saliva flowing out of the glass tube very carefully and recorded it in his notebook in detail. A new assistant counted for a while and felt bored.

Pavlov solemnly said to him, "If science needs it, give him ten or twenty years!" At the age of 87, Pavlov contracted hepatitis and later pneumonia, but he still worked as a "hard worker of science". He also feels very sorry that he has not fully fulfilled his obligations to mankind as a scientist.

Fourth, radar

In the British magazine Pink Sleeping 1947 1 Month, a scientist published a funny article, explaining to us how bats guide themselves to fly in the dark, no matter how dark or narrow, they will not hit the wall. What is the reason? How does it understand that there are no obstacles ahead?

1940, two American biologists Griffin and Garangbao used a natural radar to prove that bats can avoid collisions, but sound waves replaced electromagnetic waves, which are completely similar in principle. The bat's mouth emits extremely high-frequency sound waves, which are beyond the range of human hearing.

Two scientists used a special electronic device to record the high-frequency sound waves emitted by bats during flight. This kind of sound wave will inevitably turn back when it hits the wall. Its eardrum can distinguish the distance of obstacles and fly in the right direction. Like radar, bats emit sound waves at short intervals and very regularly.

And each bat has its own natural frequency, so that bats can distinguish their own voices without disturbing them. For this reason, when a bat flies, it often opens its mouth. If you shut its mouth tightly, it will lose its command function. If it blocks its ears, it will hit the wall and cannot fly. This interesting experiment revealed its secret.

Verb (abbreviation for verb) Nobel Prize

Nobel's father is a talented inventor who devoted himself to chemical research, especially explosives. Influenced by his father, Nobel showed a tenacious and brave character from an early age. He often goes to test explosives with his father. Years of studying explosives with his father also made his interest quickly turn to applied chemistry. He began to study nitroglycerin.

This is a difficult journey full of danger and sacrifice. Death has always been with him. An explosion experiment exploded and the laboratory was blown up without a trace. Five assistants were killed, even his brother. This amazing explosion gave Nobel's father a very heavy blow and died soon.

His neighbors, out of fear, also sued Nobel to the government. Since then, the government has not allowed Nobel to conduct experiments in this city. But Nobel is indomitable. He moved his laboratory to a boat in a suburban lake to continue his experiment.

After long-term research, he finally found a substance that is very easy to cause explosion-mercury fulminate. He used mercury fulminate to make explosive detonator, which successfully solved the problem of explosive detonation. This is the invention of detonator. This is a major breakthrough on Nobel's scientific road.
