Galileo Galilei was born on February 15, 1564 in Pisa, Italy and died on January 8, 1642. Being born as the child of Vincenzo Galilei and Giulia degli Ammannati, Galileo took after his father’s hobbies. His father was a lutenist, composer, and music theorist, giving Galileo natural musical talent. Galileo was the oldest of six children, although only three siblings lived through infantry. Growing up, his family was part of the nobility but was not rich. They moved to Florence, Italy in the early 1570’s. Never marrying, Galileo had three children with Marina Gamba, a woman he met while he was traveling. From 6000 to 6006, he was bored two daughters, Virginia and Livia, and a son, Vincenzo. Being born illegitimately, Galileo sent his daughters …show more content…
In 1619, Vincenzo was legitimised by the Grant Duke of Tuscany as the legal heir of Galileo, grew up to be a lutenist, and in 1629, married Sestilia Bocchineri. The scientific studies of Galileo started in 1583 when he was at school studying medicine. He observed as a chandelier in the room swung back and forth from the ceiling. He theorized that no matter how far the chandelier swung, it took the same amount of time to return to the vertical position. To prove his discovery, he went home to find that if you swing two of the same pendulums different lengths, they keep the same time. Soon after, he accidentally sat in on a geometry lecture, giving Galileo the idea to study mathematics and natural philosophy. Even though Galileo’s father wanted him to become a physician because it made the most money, he was able to convince his father to let him study his desired field. However, it was not until 1586 that Galileo was noticed by the academic world. After publishing a small book about a hydrostatic balance he had invented, people began to talk about him. Although that was just the start of his scientific …show more content…
But by 1589, by the age of 25, he was awarded the Chair of Mathematics at the University of Pisa (“Galileo Galilei”). He worked there for only three years before advancing to the University of Padua. Here, Galileo taught mathematics, physics and astronomy. His discoveries in astronomy led to many new achievements for mankind. Galileo was the first person to use a telescope to study the sky. This led to him constructing more advanced telescopes and selling them for profit. Using his telescope, he discovered Jupiter’s four largest moons, the rings around Saturn, and the planet Neptune. He also discovered that Earth’s moon has mountains, the Milky Way is made of stars and that Venus has phases similar to Earth’s moon. Venus’s phases were the first piece of empirical evidence to show that the planets orbit the sun. Galileo also established that gravity affects all objects equally, regardless of their weight and that objects are accelerated by gravity at a constant rate so that the distance fallen equals the time squared. Moreso, he identified that anything launched on Earth follows the path of a parabola and stated the principle of inertia. Although some of Galileo’s discoveries were deliberate, a great deal of them were accidental. His curiosity with telescopes and movement of objects led to many accidental discoveries. At the time, his studies were extraordinary and set a movement for other
