There are also characters in history who stumbled upon the truth

Fleming was a British scientist and the discoverer of penicillin. When Fleming was a military doctor, he saw many soldiers dying in pain because of infected bacteria in their wounds, and he was determined to find a cure for diseases caused by bacteria. During the experiment, he stumbled upon penicillin.

This miraculous drug has saved countless lives, and it is a success that he and several scientists have achieved through the joint efforts of several scientists. Fleming was awarded the Nobel Prize in Medicine. He said:

Opportunities are reserved only for the prepared mind. ”

There are also the stories of Newton and the apple, Leonardo da Vinci and the egg, Einstein and the little stool, and Washington and the cherry tree.

Many famous scientific discoveries have been made through a series of experiments and studies, rather than by chance. Here are some representative examples of scientific discoveries:

The Law of Universal Gravitation: Proposed by the English physicist Isaac Newton during the 17th century. Based on his observations of planetary motion and an extension of Kepler's work, he concluded the law of gravitation.

This law played a huge role in subsequent scientific research and became an important basis for understanding astrophysics and cosmology.

Electromagnetic wave theory: proposed by the British physicist Maxwell in the mid-19th century. Based on the study of electrostatic and magnetic fields, he found that there was a correlation between them, and thus proposed the theory of electromagnetic waves based on chains.

This theory has been widely used in the fields of communication and wireless canopy technology.

DNA double helix structure: proposed by American biologists Watson and Crick in the mid-20th century. Through the analysis of X-ray diffraction images, they found that DNA exists in a double helix structure.

This discovery provided an important basis for later genetics and biological research.

To sum up, scientific discoveries are often the result of systematic research and experiments, rather than accidental discoveries. The above three examples are very famous scientific discoveries in history and provide profound inspiration for later scientific research.

The story of Newton and Apple.

As a teenager, Newton found the apple on the ground. Newton was born on December 25, 1642, into a peasant family in the village of Woolthorpe, Lincolnshire, England. At the age of 12, when he was a student at the public school in Grantham, he showed a keen interest in experiments and mechanical inventions, making his own water clocks, wind mills and sundials.

The apple landed on the ground and caught his attention by accident. One hot noon, while Newton was resting on his mother's farm, a ripe apple fell, which hit Newton right on the head. Newton thought:

Why don't apples run up and fall down? He asked his mom, who couldn't explain either. When he grew up to be a physicist, he thought of the story of the teenager's "apple falling to the ground", which may have been caused by some force of the earth that attracted the apple to fall.

Thus, Newton discovered gravity.
