Did Leonardo da Vinci have contributions or masterpieces in the natural sciences?

There are a lot of them. Astronomical aspects.

Leonardo da Vinci had a negative view of the traditional "geocentric theory". He believed that the earth was not the center of the solar system, let alone the center of the universe, but only a planet orbiting the sun, and the sun itself was not moving. Leonardo da Vinci also believed that the moon itself does not emit light, but only reflects the sun's brilliance.

These ideas were put forward before Copernicus's "heliocentrism", and even at that time, da Vinci may have fantasized about the use of solar energy.

Physical aspects. Leonardo da Vinci rediscovered the concept of liquid pressure and proposed the principle of the communicator. He noted

The civilization theory left by Leonardo da Vinci to later generations is that in the communicator, the level height of the same liquid is the same, the height of the liquid level of different liquids is different, and the height of the liquid is inversely proportional to the density. In the 15th century, he was the first to begin the study of the theory of friction between objects. He discovered the principle of inertia, which was later proved by Galileo's experiments.

He believed that a projectile initially rises in an inclined straight line, displaces in a curve under the combined action of gravity and impulse, and finally exhausts the impulse and moves vertically under the action of gravity. It also foreshadows the atomic principle of matter, vividly describing the power of atomic energy: "The thing will explode from the ground, causing a sudden death in a silent breath, and the castle will be completely destroyed, and it will seem to have great destructive power in the air."

Medical aspects (autopsies were against religion at the time, but Leonardo da Vinci privately dissected more than 20 corpses).

Leonardo da Vinci also made great achievements in physiological anatomy and is considered the ancestor of modern physiological anatomy. He mastered the knowledge of human anatomy, starting with anatomy, and studied the structure of various parts of the human body. He was the first to use wax to represent the internal structure of the human brain, and was the first to envision the use of glass and ceramics to create hearts and eyes.

He discovered the function of blood, believed that blood plays a metabolic role in the human body, and believed that blood is constantly circulating. He said that the blood constantly transforms the whole body, bringing nutrients to all parts of the body that it needs, and then taking away the waste products from the body. Leonardo da Vinci studied the heart, discovered that the heart has four chambers, and drew heart valves.

He believes that one of the causes of death in the elderly is arteriosclerosis, which is caused by lack of exercise. Later, the British scientist Harvey confirmed and developed the results of Leonardo da Vinci's physiological anatomy.

Paleontological pioneers.

Although he has been dead for almost 500 years, we remember that in this typical Renaissance man, one of his interests was the study of fossils. In the new journal ** Palaios, André Baucon shows that he was a "pioneer in the study of body fossils," or once biological remains, with "fossil remains, such as footprints".
