Galileo Galilei Biography

Galileo Galilei Biography: Galileo Galilei was born on February 15, 1564, in Pisa (now in France), a famous Italian city. From childhood, Galileo was inclining towards medical science, but later his interest increase towards physics.

Galileo was also one of the greatest figures of those who laid down their lives in search of truth. Galileo was an Italian astronomer, physicist, and mathematician. He was the first person to use a telescope to make astronomical observations, discover craters and mountains on the Moon, and the four satellites of Jupiter. He observes the phases of Venus and also found the rotation speed of the Sun by studying the solar spots.

The doctrines propound by Galileo contradict religious beliefs, for which Galileo sentence to life imprisonment for tampering with divine beliefs.

The story of Galileo Galilei and the pendulum

When he was 17 years old and studying lore, one evening he went to the cathedral in his hometown of Pisa. Then a church doorman lit a lamp hanging from a chain. As soon as he removed his hand, the lamp started swinging with the chain left and right. Seeing the lamp swinging, Galileo realized that the time of the lamp to swing (oscillations) remains the same whether the distance of the vibration is large or small.

Being a student of medical science, he knew that each heartbeat of a human pulse takes the same amount of time. So to test his ideas, he decided to count the beats of his pulse to find the exact number of oscillations of the lamp. In this test, his assumption proved to be true. He found that oscillations, small or large, take the same amount of time for everyone. On the basis of this fact, the idea of making an instrument was born in his mind, which today calls a simple oscillator.

On the basis of this fact, he invented an instrument called ‘Pulse Meter’. Many years later, when Galileo was old and blind, his son Vincenzi made models of wall clocks on this basis. Even today, wall pendulum clocks make on the basis of this invention.

Galileo Galilei and his inventions

Galileo leaned Pisa to prove Aristotle’s statement – “If two objects of different weights are drop simultaneously from the same height, the object of greater weight will fall on the ground earlier than the object of lesser weight”. The 180 feet high tower chosen.

One day in 1590, he climbed up from the living and climbed on the balcony of the seventh floor of this tower. They also took with them two metal balls, one weighing a hundred pounds and the other only one pound. Galileo looked down from the balcony That there is a crowd of thousands of people standing to see this experiment of his. The crowd also included many professors, philosophers, and students from the University of Pisa.

Galileo carefully balances both the goals on the outer edge of the roof of the balcony. Then both the goals drop simultaneously. Most of the people believe that Galileo would prove to be a fool in front of everyone, but his surprise knew no bounds, as both the balls hit the ground simultaneously.

In this way, a belief that has been going on for years has been proving wrong on seeing it. People may have different views about how much truth is in this story, but it is true that Galileo had deliberate a lot about gravity so many years ago, and probably on this basis he would have taken this fact can prove it.

Galileo Galilei and Copernicus 

Galileo confirms the views of Copernicus. Copernicus said that the Sun is the center of the universe, not the Earth. Galileo replaces this theory by saying that the Earth is not the center of the universe, but the Earth and all the other planets revolve around the Sun. In 1616, when Galileo declare the stability of the Sun and the theory of the Earth’s rotation, he had to appear before church officials two days later. He officially warns to stop promoting the idea.

After this, he did his famous book ‘Dialogues Concerning the Two Principal Systems of the World’ in the religious court. In this book, he expresses his views openly. Base on this, he prosecutes and this 70-year-old scientist had to appear in court again.

Galileo was put under pressure to be forgiven if he believes his statements to be false. It is said that when Galileo stood up in court to deny his beliefs, his heart fills with remorse. then he looks to the ground And whispering he said, “The earth revolves around the sun. For this, the old scientist had to spend jail time.

last moments of Galileo Galilei’s 

In 1637, Galileo went blind, and in January, He die in prison in 1642. He was such a scientist who engages in the search for truth throughout his life. Even today his name is taken with great respect.
