Galileo is known as science's most dramatic character. He is known as a rebel philosopher who advocated free though in a country where individual opinion was detested. He confronted authority and tradition by putting his beliefs in his scientific work before those of religion. His concept of questioning and searching for the truth led to many discoveries such as the isochronism of the pendulum, disapproving the accepted Aristotelian concept of the fall of weights, construction of the telescope which was a far more powerful instrument that anyone had ever seen and through it he discovered satellites of Jupiter as well as many others.......
             Born of an in Pisa, Tuscan on February 15, 1564, Galileo was the oldest son of Vincenzio Galilei. (Book Galileo, page 59) When he was a young boy his family moved to Florence where he received his early education in a nearby monastery. Then in 1581 he was sent to the University of Pisa to study medicine. Galileo had little interest in medicine and found his classes boring. But his active and curious mind led him into the world of science. He was sitting in the cathedral at Pis while the lamps were being lighted. He noticed that the lamps were swinging and some had wider arcs then others. He expected that the lamps with the wider swings would require more time so he timed them by the beat of his pulse and found that all the swings took the same time. The lamp was acting like a pendulum and these observations showed that any pendulum must therefore be isochronous, performing all swings in equal times. He also implied his findings about pendulums to invent a timing advice. What was most important is that Galileo had set the pattern of his life. A simple observation led him to questions and experiments which led to new knowledge and applications.
             The first sign of him being a rebel was shown when he decided to leave medical school without a degree and return to Florence against his father&...
