The Journey of a Scientist Who Changed the World
Presentation mode ideal for classroom projection
Galileo changed the way we understand the universe by developing the scientific method and challenging geocentric conceptions, paving the way for modern astronomy and physics.
Galileu Galilei was born on February 15, 1564, in Florence, Italy. His father, a merchant, encouraged him to study and use reason to understand the world. From an early age, Galileu was fascinated by the mechanics of machines and the secrets of the sky.
He studied at the University of Pisa, where he learned about mathematics and physics. Still, his heart was turned toward the stars, and he began building simple instruments to observe the night sky.
Galileu improved the telescope, making it more powerful than earlier models. With it, he observed the craters of the Moon and discovered four moons around Jupiter, called the Galilean moons.
These discoveries showed that not everything revolves around the Earth, which was a revolutionary idea for the time.
Galileu wrote letters explaining that the Sun was the center of the universe, and that the Earth orbited around it. This theory, called heliocentrism, contradicted the geocentric view accepted by the Church.
He continued to observe planets and record their movements, proving that Copernicus's theory was correct.
In 1633, Galileu was tried by the Inquisition for supporting heliocentrism. He was condemned to renounce his ideas and spent the rest of his life under house arrest.
Even so, he continued to write and teach, keeping the flame of science alive.
During his imprisonment, Galileu continued to study physics, discovering laws of motion and the fall of bodies. He also wrote about the nature of sound and light.
He died in 1642, but left a legacy that inspired generations of scientists.
Today, Galileu is remembered as the father of modern science. His scientific method, based on observation and experimentation, is the foundation of scientific research.
The planet named Galileu, the star 51 Pegasi b, and many other scientific names honor his work and his infinite curiosity.
