Galileo Galilei Biography | Biography of Galileo Galilei


Galileo Galilei is known among inventors of the world for his laws of motion, gravity and telescope invention. Galileo Galilei had to pay the price for his invention by sacrificing his life. The great gift he gave to the world through his important discovery is priceless. Come, let us introduce you to the biography of Galileo Galilei.

Galileo Galilei was born on 15 February 1564 in the city of Pisa, Italy. His father’s name was Vincenzo Galilei, who was a music theorist. His mother’s name was Julia (Giulia). Galileo Galilei was the eldest of seven siblings. His family was very poor. He received his early childhood education in Florence. When he grew up, he contributed to his father’s work. His father resumed his studies knowing him as talented. In 1581, he continued his studies by taking admission in medical science.

His interest in medicine was more towards scientific invention. Galileo Galilei’s father died in 1591. As a grown-up, the responsibility of mother and siblings fell on Galileo Galilei. Amidst the severe financial crisis, Galileo found it very difficult to raise the amount of dowry for the marriage of his sisters. The dowry practice was prevalent in Italy at that time. Galileo opened tuition as well as clothing stores and mathematics equipment to improve economic conditions, which benefited him financially. Among these family responsibilities, Galileo engaged in studies and teaching.

On 4 April 1597, Galileo Galilei built a telescope that could see 32 times as large. In his shop, Galileo started selling it in 1609. The telescope that was being sold at that time was used for some distance viewing. This telescope has proved that the sun is a mashed spot. The galaxy is a cluster of stars. Jupiter has many satellites. People who believe in Catholicism were very critical of Galileo’s telescopic invention. In the Bible, it was written that the sun rotates and the earth is fixed. Galileo opposed this theory and proved that the earth rotates. Galileo wrote these principles in detail in his book.

This theory of Galileo Galilei was prosecuted by his opponents, whose purpose was to prove Galileo guilty and punish him because he did not want to accept the wrong things written in the Bible about the Earth and the Sun. Galileo prosecuted as anti-religion. Once during university education, Galileo was passing by the church in Pisa city, Italy, he saw a man stopped near the street lamp-post with oil keg in his hands. He lowered the handi hanging above the post with a rope and filled it with oil. Burn it, put it in the handi and close the lid of the hand, burn the lamp and then climb it up with the help of rope.

The child saw that as much as she shakes her left hand, she also moves to the right. He recorded the time of going in both directions and gave the pendulum theory. A hundred years later, Holland‘s scientific hygen invented the pendulum clock. While studying in the university, Galileo decided that he would study only mathematics and physics. He was denied studies for not being able to pay university fees.

Returning to Florence, he recalled the handi incident and connected it to the watch. If something is hung in the clock, it will move with the tick of the clock. If the speed of the pendulum is slow, then understand that it is about to stop. Stopping will mean filling the key in the clock. Mixing the speed of the pulse of the body with the speed of the clock, see that if the speed is more or less than the tick of the clock, then the speed of our body is not normal. The person is unhealthy. The fast and slow pulse of the pulse is a symptom of the disease in terms of healing. This discovery of Galileo for healing of the human body was very useful. The instrument he made to examine it was called pulsimeter.

Galileo Galilei, in one of his important discoveries, misunderstood Aristotle’s theory that if low-weight and over-weight objects are dropped from above on Earth, the over-weighted object will fall quickly. After breaking the tower of Pisa, he dropped more and less weight goals simultaneously. Religious leaders, scientists, teachers and intellectuals gathered to see this historical experiment. People clearly saw that both the spheres came down together.

In this way, people proved Aristotle‘s theory to be wrong, instead of praising him, he condemned them. He described them as arrogant, condemning the elderly. Unhappy Galileo did not leave the path of invention and discovery. Galileo, describing the miraculous events in the sky with his telescope, also presented important theories in the field of astronomy, which included rational ideas on sound, light, color and texture of the world. In 1611, Galileo was honored for inventing the telescope. Went Galileo prepared a hydrostatic balance in 1585–86. It became easy to guess the properties of different liquids. After three years, he gave the rules of motion of solid materials. Because of his inventions, he came to be called the modern Archimedes.

In 1632, when Galileo Galilei, in his research book, described the sun as the center of the universe, not the earth, and the earth as unstable and the sun stable, he was attacked by fundamentalists as anti-religion. He was kept out of sight for eight years. During this, he continued the creation sequence. In 1637, he had become completely blind. On 8 January 1642, he was gripped by fever. In this way a great scientist died. Newton put forward the rules that Galileo Galilei proposed about his speed and gravity. The last moments of life were painful for him.
