Benjamin Franklin was an American scientist, physicist, social activist, and democrat during the bourgeois revolution. Born on January 17, 1706 in Boston into a working class family. He entered primary school in 1714 and only studied for two years. In 1718, when he was 12 years old, he started working as a printing apprentice. But he was very yearning for science, diligently studied on his own, and mastered many foreign languages ??such as Italian and Spanish as well as extensive knowledge of natural sciences. Because of his genius and hard work, he finally became a great scientist and inventor that attracted worldwide attention.

The electric lights, telephones, telegraphs, and trams that people use every day, up to the cutting-edge technology Invention and utilization are inseparable from electricity. However, about 250 years ago, people were still ignorant about electricity. At that time, Westerners called thunder and lightning "God's fire."

Benjamin Franklin, the outstanding American inventor, began to study the phenomenon of electricity in 1746. Through repeated experiments and summary, he published the famous basic theory of electricity "Experiments and Observations of Electricity" in 1751. The book immediately caused a sensation throughout Europe. From then on, Franklin became the founder of electricity.

Franklin was born in Boston on January 17, 1706. He went to school at the age of 8, became an apprentice in a printing office at the age of 12, and became a printer from the age of 17. Franklin worked hard and studied diligently. His wide range of interests, strong curiosity, hard work and determination to achieve his goals, as well as his dedication to science laid the foundation for him to become an influential scientist.

Franklin was one of the first people in the world to conduct electrical experiments. He was the first person in the history of electricity to correctly explain the nature of electric charge. He put forward an important hypothesis in the history of electricity: electricity is an element that exists in all substances in a certain proportion under ordinary conditions. He also discovered that electricity can be transferred from one object to another, and the total amount of electricity in any insulator does not change. This conclusion is the so-called law of conservation of charge in modern electricity. Franklin also used the mathematical concepts of positive and negative for the first time to explain the properties of two kinds of charges, explained the source of electricity and its existence in matter, and explained the characteristics of some dielectrics.

In July 1752, Franklin risked his life to conduct an experiment that shocked the world. The reason was that he listened to a speech by a European electrical appliance scholar and was inspired. He wondered, is thunder lightning? So he immediately tried to collect the lightning from the thunder into the Leyden bottle. On a thunderstorm day, he used a square silk handkerchief to make a kite. The kite was tied with a thin metal wire and a ribbon, and the other end was knotted in a circle of keys. When the kite is flown into the sky, lightning is transmitted through the metal kite string to the key, which can charge the Leyden jar. The experiment was successful and it proved Franklin's theory correct. So people say: "It was Franklin who separated God from thunder and lightning."

Franklin was not only a great scientist, but also an outstanding politician. He participated in the U.S. Declaration of Independence and The drafting of the U.S. Constitution made a significant contribution to the final victory of the Revolutionary War.

On April 17, 1790, Franklin died of illness in Philadelphia at the age of 84. In 1900, Franklin was among the first to be inducted into the American Hall of Fame.
