Galileo Galilei's Contribution To Science

“You cannot teach a man anything; you can only help him find it within himself”. This is a famous quote by the genius Galileo Galilei an astronomer, physicist, mathematician, engineer, and and philosopher. He is well known for his contributions to astronomy, his scientific innovations, and his several published works. Many of his contributions to science are still used today. Galilei greatly impacted world history. Galileo, the son of Vincenzo Galilei, a composer and music theorist, was born on February 15, 1564 in Pisa, Italy. His name was decided using a tradition, in which the first name is a slight variation of the last name. Galileo was originally tutored, but was later educated in a monastery near Florence after his family moved. In

WHile enrolled at the University of Pisa, he realized how objects swing back and forth in a pendulum, and expanded the pendulum theory, realizing that smaller swings and larger swings will move at the same speed, regardless of the size of the swing. He invented a time measuring instrument that led to the inventions of heart rate monitoring and grandfather clocks later. In 1585, he expanded Archimedes's work on hydrostatic balances, a device that can measure gravity, by weighing the object in water, giving him a greater reputation is science. In 1593, Galileo invented a device used to measure temperature. In 1597, he added scales to compasses, improving their usability. He challenged the theory that light objects fall at a faster rate than heavy objects, and applied algebra to geometry. This law was used by Isaac Newton when the theory of gravity was developed. He also showed that if you were to increase the dimensions of a structure equally, it would be weaker. After hearing about the invention of the telescope, he invented and perfected his own in 1609. It allowed three times the magnification of objects that other telescoped offered, and became widely used by sailors. For this, he was offered to work at the University of Venice for his life, which he accepted. Galileo’s interest in science slowly transitioned from physics to

He first shifted his attention to Astronomy in 1604, when he witnessed a supernovae, and stated that the object was further away from earth than the planets, and objected to Aristotle's reasonings that the heavens were unchanging. In 1609, he improved the model of the telescope, leading to his relocation to the University of Venice. With this new telescope he could see jagged edges on the moon, and pointed out that these were mountains. However, he believed that the darker spots on the moon were actually oceans, which was incorrect. Galileo studied Saturn, and noted its irregular ovular shape, but was unable to realise that it was caused by its rings due to his updated telescope being used to its magnification extent. He then found four large objects in space, which he noted were not stars, and were, in fact orbiting the planet Jupiter, and determined the time it took for one to orbit the planet. He also determined the speed to the rotation of the sun. He displayed proof that the Copernican theory was correct, and defended it. He wrote and published several books that lead to conflicts between him and the Roman Catholic
