Ptolemy s Earth Centric Theory is not science

Mistake. He believed that the earth is the center of the universe and that everything revolves around the earth, which can now be said to be very probable and wrong. The moon revolves around the earth, the earth revolves around the sun, and the solar system revolves around the axis of the Milky Way, as for the Milky Way, I don't know, but it can be speculated that the Milky Way moves irregularly.

The Ptolemaic system believed that the Earth was not the center of the universe. () Naichang ruler.

Ptolemy based on the views of Eudox to develop geocentrism.

Geocentrism was first proposed by the ancient Greek scholar Eudox, and was gradually established and perfected by Aristotle and Ptolemy. Ptolemy believed that the Earth was stationary at the center of the universe. From the Earth outward, there are the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn, which orbit the Earth in their respective orbits.

Eudox thinks that the planets are a system of the central sphere around which they revolve, and at the same time revolve around the third sphere, and so on. Just as the moon rotates around the earth, the earth-moon system rotates around the sun. The rotation of each sphere is uniform, but the rotation of each sphere and the sum of the inclination of the orbital sphere poles of the first sphere and the poles of the orbital sphere of its adjacent rank determine the entire motion of the planet, and this motion is the irregular motion that is actually observed.

Geocentrism was proposed by Ptolemy.

The Earth is at the center of the universe and stands still. Each planet rotates at a constant speed in a small circular orbit called the "Wheel", and the center of the Wheel rotates around the Earth at a constant speed in a large circular orbit called the "Wheel", but the Earth is not in the center of the Wheel, but at the center of the circle. The centers of Mercury and Venus are located on the line between the Earth and the Sun, and the center of the cycle rotates once a year on the mean cycle, and the straight line from Mars, Jupiter, and Saturn to their respective centers always coincides with the Earth-Sun line, and these three planets revolve around their center once a year.

Stars are all located on solid shells called "sidereal days". In addition to the above-mentioned movements, the sun, moon, and planets also revolve around the earth every day together with the "sidereal sky", so that various celestial bodies rise in the east and set in the west every day.

It was in ancient Rome that astronomy was really founded and the trajectories of many celestial bodies were calculated.

of Ptolemy. While today we may laugh at Ptolemy's simple mistakes, anyone who truly understands Ptolemy's contributions will be in awe of him. Ptolemy invented spherical coordinates, which defined the longitude that included the equator and zero degrees of longitude.

Among the latitude and longitude, he proposed the ecliptic, and also hailed the radian system.

Of course, his biggest and most controversial invention was geocentrism. Although we know that the earth moves around the sun, at that time, it was easy to conclude that the earth was the center of the universe based on people's observations. The trajectories of the planets were irregular from the point of view of the earth, and Ptolemy's greatness was that he accurately calculated the trajectories of all the planets by the method of forty small circles and large circles.

Ptolemy succeeded Pythagrass.

Some of the ideas that he also considered the circle to be the most perfect geometric figure. The degree of refinement of the Ptolemaic model has amazed all subsequent scientists. Even today, with the help of computers, it is difficult to solve the equation of forty circles set together.

Every time I think about this, I sincerely admire Ptolemy. For 1,500 years, people have decided on the time of farming based on his calculations. However, after 1,500 years, Ptolemy's cumulative error in the sun's motion was still one week short.

Philosophically, it should have been scientific at the time.

It must be science, and at that time, the "geocentric theory" was put forward to help Wang slowly help people solve many astronomical problems. Lingqing's "geocentric theory" has also been rated as one of the top 100 discoveries in human astronomy. At that time, it broadened people's understanding of the universe and inspired people to explore the universe in depth and seek friendship and knowledge.

It can be said that without the "geocentric theory", there would be no "heliocentric theory" and various later astronomical discoveries.

Not scientific, the center of the solar system is the sun.

Unscientific, his doctrine was only established as the orthodox doctrine of the time because it was conducive to the mind control of religion.
