Answer: Copernicus heliocentric theory. Kepler laws on the motion of the planets. Galileo Jupiter Moon Detection.
Explanation:
- Copernicus between 1510 and 1514 created the first sketch of the heliocentric theory. Copernicus explained the rotation of the Earth around the Sun and defined the change of seasons by the process of touring the Earth around the Sun. Towards the end of his life, he published a piece entitled "On the Rotation of the Heavenly Circles" in which he advocated a heliocentric model of the universe. Changed the calendar. He determined the existence of a triple motion of the Earth and its rotation about the axis, as well as the procession of the Earth's axis. Copernicus also established that the moon is not a planet.
- Kepler was a German astronomer and mathematician. Kepler discovered regularities in planetary motions known as Kepler's laws. The first two laws were published in 1609. In the same year, he described how the moon affects the tide. Kepler also contributed to modern optics by creating a telescope.
- Galileo was an Italian astronomer, mathematician and philosopher. One part of his life was in the Italian city of falls, where he studied mechanics, free fall, horizontal shot, and considering the thermal expansion of liquids, he also constructed the first thermometer. In 1609 he also made the first binoculars. This invention led to a revolution in the study of celestial bodies. Therefore, Galileo soon confirmed the Copernican theory, which brought him into conflict with the church. In 1616 the church forbade this teaching. Galileo is best known for his statement "Eppur si muove" or Still moving, which he allegedly uttered either after the trial or upon house arrest, thinking that the Earth was orbiting the Sun after all.
