Today virtually every child grows up learning that the earth orbits the sun. But four centuries ago, the idea of a heliocentric solar system was so controversial that the Catholic Church classified it as a heresy, and warned the Italian astronomer Galileo Galilei to abandon it.
View Larger Image Italian astronomer Galileo Galilei provided a number of scientific insights that laid the foundation for future scientists. His investigation of the laws of motion and improvements on the telescope helped further the understanding of the world and universe around him.
Both led him to question the current belief of the time, that all things revolved around the Earth. Experimenting with balls of different sizes and weights, he rolled them down ramps with various inclinations. His experiments revealed that all of the balls boasted the same acceleration independent of their mass.
He also demonstrated that objects were thrown in the air travel along a parabola. At the same time, Galileo worked with pendulums. In his were thrown accurate timekeeping was virtually nonexistent.
Galileo observed, however, that the steady motion of a pendulum could improve this. Inhe determined that the time it takes a pendulum to swing back and forth does not depend on the arc of the swing. Near the end of his lifetime, Galileo designed the first pendulum clock.
Instead, he significantly improved upon them. Inhe first learned of the existence of the spyglass, which excited him. He began to experiment with telescope-making, going so far as to grind and polish his own lenses. His telescope allowed him to see with a magnification of eight or nine times.
In comparison, spyglasses of the day only provided a magnification of three. He was the first to see craters on the moon, discover sunspots, and track the phases of Venus. The rings of Saturn puzzled him, appearing as lobes and vanishing when they were edge-on — but he saw them, which was more than can be said of his contemporaries.
And recent research seems to imply he discovered Neptune two centuries before it was officially known. Of all of his telescope discoveries, he is perhaps most known for his discovery of the four most massive moons of Jupiter: Io, Ganymede, Europa, and Callisto, now called the Galilean moons.
Supported by the Catholic Church, teaching opposite of this system was declared heresy in Galileo, however, did not agree. Inhe was summoned to Rome and warned not to teach or write about this controversial theory. But inbelieving that he could write on the subject if he treated it as a mathematical proposition, he published work on the Copernican system.
He was found guilty of heresy and was placed under house arrest for the remaining nine years of his life.Galileo Galilei Galileo was born in Pisa (then part of the Duchy of Florence), Italy, the first of six children of Vincenzo Galilei, a famous lutenist, composer, and music theorist; and Giulia Ammannati.

Experience Historical journeys Galileo’s Italy I Galileo Galilei (–) was born in Pisa and taught mathematics at Padua. Galileo Galilei () was a Tuscan (Italian) astronomer, physicist, mathematician, inventor, and philosopher.
He was born in Pisa, and was the oldest of six children in his family. When he was a young man, his father sent him to study medicine at the University of .
Galileo Galilei (Italian: – 8 January ) was an Italian polymath. Known for his work as astronomer, physicist, engineer, philosopher, thanks to accurate translations by Tartaglia and others; but by the end of Galileo's life, it was being superseded by the algebraic methods of caninariojana.com for: Kinematics, Dynamics, Telescopic observational astronomy, Heliocentrism.
