An Italian physicist and astronomer named Galileo Galilei founded modern science. He studied and researched many areas of what is now called physical science. Among other innovations, one of his more famous discoveries was changing the worldview of how the sun revolved around the earth. Galileo found through his research that the earth revolved around the sun, disputing the belief held by The Roman Catholic Church that the earth was the center of the universe. He refused to obey orders from Rome to terminate discussions of his theories and was sentenced to life imprisonment. Galileo's theories and inventions that were thought to be unconventional are now the baseline of modern science today.

The life of Galileo Galilei began in Pisa, Italy on February 15, 1564. His family was of lower nobility, which did not hinder the greatness he was to later achieve.

In 1574, he and his family moved to the town of Florence where he attended monastery school. Galileo was later withdrawn from monastery school by his father in 1579, presumably because of too much religious influence.

... current views. His research and interest to solve theoretical and scientific problems launched his success, making him one of the most renowned scientists of all time. His discoveries and theories, although at the time were thought of as unorthodox, proved to be most meaningful to modern science today. Galileo is not only dubbed as the "father of modern science", but truly was the founder of most theological and scientific methods used today.
