Galileo's discoveriesHe designed some mechanical devices driven by his fascination, which he pursued throughout his life. He made a pump that required only one horse to operate and move huge volumes of water, Galileo built his telescope, in 1609. He began to explore the sky using his telescope and discovered that the moon shines with reflected light. He also said that the moon has an irregular and mountainous surface. He continued his exploration and added that the Milky Way is made up of various stars scattered across the sky. Say no to plagiarism.

Get an Original Essay In the year 1610, Galileo explored the 4 largest satellites of the planet Jupiter, the first satellites of a planet excluding Earth to be determined. He observed the oval shape of the planet Saturn, the phases of the planet Venus and the spots of the sun. With his continuous studies and observations he confirmed the acceptance of the Copernican hypothesis of the solar system. With all this information, he also proved that the universe was not perfect. Galileo's most important discoveriesThe Earth's orbitAfter the invention of the telescope in the Netherlands, Galileo began producing his own lenses for glasses. He managed to build increasingly powerful telescopes, which helped him monitor the solar phases of the planet Venus. It also went through phases similar to those of the moon and after observing Venus concluded that the sun must be the central point of the solar system, and not the Earth as previously thought. The Pendulum Principle In the Great Cathedral Galileo noticed that a lamp swinging overhead required exactly the same amount of time for each swing, even as the distance of a swing became progressively shorter. This principle made Galileo famous and was also used to regulate clocks. The law states that “a pendulum will always take the same amount of time to complete one swing because there is always the same amount of kinetic energy in the pendulum that is simply transferred from one direction to another.” The Law of Falling BodiesThis law states that “all objects will fall at the same speed, taking into account relatively minor differences in aerodynamics and weather conditions.” To demonstrate this, Galileo began dropping objects of different weights onto the top of the Leaning Tower of Pisa. All objects took the same time to reach the ground. It was against the law established by Aristotle that the speed of fall of a heavy object was not proportional to its weight.

Customize EssayThere were many astronomical discoveries by Galileo, which people today simply accept as common sense. Galileo discovered that the surface of the moon is rough and irregular, furthermore in 1610 he managed to discover four moons rotating around Jupiter. Even more important was the fact that there are many more stars than are visible to the naked eye, which was a shocking surprise to the scientific community of that time..
