Galileo Galilei’s Biography
      Galileo Galilei was born on February 15th, 1564 in Pisa, Italy. He was the eldest child of Vincenzo Galilei and Gulia Ammannati. For the first years of his life, he lived in Pisa, but the family later moved to Florence.   During his teen years, Galileo attended a Jesuit monastery school, and then in 1581 furthered his learning by attending the University of Pisa (where he studied medicine).   After discovering his love for mathematics and philosophy, he changed his major.   Later, he left university, without a degree, and began teaching mathematics in Florence and Siena. During this time her wrote his first book The Little Balance. He then started his studies on motion, which continued for the next two decades.
      In 1609, after he heard about the telescope, he started to work on the optical theory of

Its operation. He went on experiment with accelerated motion. His book Two New Sciences, illustrated that there were two concepts in the science of motion. The first became the base of physics, while the science of materials and construction contributed to engineering.

Though the novel illustrated on accelerated motions, Galileo went on to analyze the speed of a fall.   Galileo established that a falling object persist to speed up (accelerate) while it falls. Based on a excerpt from Two New Sciences, he concluded that a falling object accelerates at a constant rate, and that it picks up equal amounts of speed in equal time intervals. Thus, if it falls at a initial velocity of 0 (or rest), it is moving twice as fast after two seconds as a second earlier. He tried to prove this hypothesis, by doing various experiments.

      After years of experimentation, Galileo wrote the Dialogue Concerning the Two Chief World Systems, where he compared various theories. He later ventured to Rome (to be judged on purposely disobeying the church’s teachings, which he was late found guilty of and was sentenced to life in prison). He was...
