What did Copernicus contribute to physics? 40

In 1543, Copernicus published his "Theory of the Movement of the Heavenly Bodies", which was the first to put forward the heliocentric theory, replacing the "heliocentric theory" of Ptolemy, which had been followed for thousands of years. In the book he rightly states that the earth revolves around its axis; The moon orbits the Earth; The fact that the Earth and all the other planets revolve around the Sun. Copernicus was a giant of the European Renaissance.

He devoted his life to the study of astronomy, leaving a legacy for future generations.

The first volume of The Movement of the Celestial Sphere is the essence of the book, which successively discusses that "the universe is spherical", "the earth is also spherical", and "the motion of the celestial bodies is a uniform and eternal circular motion or compound motion". Copernicus said, "This rotational motion of the celestial bodies is intrinsic to the sphere, and it reflects the characteristics of the sphere." The shape of the ball is characterized by its simplicity, no beginning and no end point, and it is impossible to distinguish the parts when spinning.

Moreover, the shape of the sphere is also caused by the rotation itself. ”

It cannot be said that there is any specific contribution.

Because the establishment of physics was an experiment-based natural science established by Galileo.

Copernicus did not have a clear concept of physics, and all his contributions can only be said to be the birth of physics that was promoted.

Astronomy 3] Copernicus and heliocentrism on stage! Contribution of prosthetic-nose astronomer Tycho Brahe.

Copernicus proposed heliocentrism. After a long period of observation of the night sky, Copernicus came up with the heliocentric theory, which is the most important and meaningful view that Copernicus came up with in his lifetime. The heliocentric theory holds that the earth is not the center of the universe, nor is it fixed, all the planets are centered on the sun, and the earth is just an ordinary planet that revolves with the sun.

People see the sun and stars moving in the sky every day because the earth itself is autobiographic.

The wrong point of heliocentrismHeliocentrism is a doctrine that, while proving that the earth revolves around the sun, is also false:

1. The sun is not the center of the universe, but the center of the solar system.

2. The Earth is not the center of gravity.

3. Any movement seen in the sky is not entirely caused by the movement of the earth.

4. The orbit of the earth and other planets is elliptical rather than circular, and does not move in a circle.

Because of these errors, heliocentrism can only be regarded as a doctrine, and it is relatively better than geocentrism. Because it proves that the earth revolves around the sun, but it also caused a great change in human understanding of the universe and a change in thinking.

Copernicus's contribution was that he used the scientific theory of the center of the sun to overthrow the theory of the center of the earth, which had ruled astronomy for thousands of years. This was a major revolution in astronomy and led to a revolution in the human universe.

Copernicus' contributions include:

1. Copernicus's Theory: Copernicus's Doctrine is a revolution in human understanding of the universe, which has brought about major changes in people's entire world view. But when assessing Copernicus' influence, it should also be noted that astronomy is not as broad in application as in physics, chemistry and biology.

Theoretically, people who knew nothing about the knowledge and application of Copernican could have built things like televisions, automobiles, and modern chemical factories, but it would have been inconceivable not to apply the theories of Faraday, Maxwell, Lavoisier, and Newton. From a historical point of view, The Theory of the Movement of the Celestial Bodies is the starting point of contemporary astronomy and of course the starting point of modern science.

2. Heliocentric theory: Before the publication of Copernicus's "heliocentric theory", the "geocentric theory" had been dominant in medieval Europe. About 1515 years ago, Copernicus wrote a treatise entitled "A Brief Theory" to expound his basic ideas about the motion of the celestial bodies, rejecting the "geocentric theory".

This is an unheard-of doctrine that has opened a new era, and it is undoubtedly a slap in the face to the Ptolemaic theory of the center of the earth that has been regarded as a definite theory in the academic community for thousands of years.

3. Movement: The immortal contribution of "Movement" lies in its explanation of the apparent motion of the planets according to the principle of relative motion. Before Copernicus, this principle had never been elaborated in such detail, nor had anyone drawn such an important conclusion from it.
