The invention of scientists, how scientists invented this and that

The microscope, a scientific instrument that everyone knows, is also available in many people's homes, do you know how it came about? It is also "played". It was invented in 1632 by Levin Tiger Sakura Bend.

At that time, his work was also very free, so he often sharpened his lenses when he had nothing to do at work, and he often sharpened them while looking at the door to make a magnifying glass. He suddenly had a whim, what would happen if they were put together, so he overlapped the two lenses, saw the ** in his hand, and made this amazing discovery, and then he used these two lenses to make a simple microscope, **, I believe many people know, ** is also "played" out. One day, Dell's assistant Thomas fiddled with the reeds he had pinched, and Bell heard the plucking of strings coming from the neighbor's hole.

On March 10, 1876, Bell shouted over a telephone: "Mr. Watson, come here!" I'm looking for you!

Assistant Watson, who had heard the summoning in the laboratory, rushed out of the laboratory as fast as he could, and ran to the dormitory where Bell had called out to him. Along the way, he kept yelling, "I heard Belle calling me just now!"

I just heard Bell calling me! ”

Scientists' discoveries and inventions are important achievements in scientific research, but they have different meanings and characteristics.

Discovery refers to the discovery of new natural phenomena, laws or facts in scientific research. For example, Newton discovered the law of gravitation, Gorwin discovered the law of species evolution, etc. Discovery often requires scientists to have keen observation and deep subject knowledge, to discover new problems and phenomena through continuous experiments and observations, and to try to explain and understand them.

Invention refers to the invention of new tools, devices, methods or theories through creative thinking and practical activities. For example, Edison invented the electric light, **, etc., von Neumann invented computer architecture, etc. Invention often requires scientists to have creative thinking and practical skills, and to design and improve new tools, devices, methods or theories through imagination and creativity to solve real-life problems and challenges.

1. Newton: a master of physical mechanics and a British scientific giant Newton. He pioneered the principles of classical physics and mechanics and laid the foundation of modern physics.

2. Roentgenium: The discoverer of X-rays, the German physicist Roentgenium. It has completely subverted the traditional diagnosis and treatment methods that have affected human beings for thousands of years to study human diseases.

3. Copernicus: The founder of the heliocentric theory, the Polish astronomer Copernicus. It broke the religious doctrine that has ruled Europe and even the world for nearly 1,000 years.

4. Edward Jenner: British internal medicine expert Edward Jenner invented and popularized a method of preventing the dreaded smallpox disease known as the Zen method - vaccination.
