Galileo Powerpoint

  1. 1. GALILEO GALILEI AND HIS DISCOVERIES By Posy, Kathy, and Arlene
  2. 2. GALILEO’S BIRTH AND DEATH DATE  Galileo was born on the 15th of February 1564 in Pisa, Italy.  Galileo died on the 8th of January 1642 in Arcetri, Italy.
  3. 3. GALILEO’S TELESCOPE  Galileo made his first telescope in 1609. He didn’t really invent the telescope. It was actually created by a Dutch spectacle maker,(Hans Lipperhey,) but when Galileo found out he made his own. His magnified objects twenty times, where as the first one could only magnified objects three times. Over time Galileo slowly improved his telescope.
  4. 4. GALILEO AND THE SUN  For years people thought the sun orbited around the Earth. Nicoulas Copernicus made a scientific guess that the Earth revolved around the Sun. A few years after Nicoulas’s death, Galileo was born. In 1610 Galileo used his telescope to confirm Nicoulas’s hypothesis. The Earth actually revolved around the Sun instead of visa versa. He also discovered the moon has creators. This to he discovered with his telescope.
  6. 6. THE PENDULUM The pendulum was discovered by Galileo. The way he discovered the pendulum, is that one day Galileo was bored , he was sitting in a church, and he saw the candelabra swinging, that gave him the idea of the pendulum. With the pendulum he made the pendulum clock, to tell time more accuartly. The pendulum also came into play in many other inventions.
  7. 7. WHAT WOULD TODAY BE LIKE WITH OUT GALILEO’S DISCOVERIES  If Galileo hadn’t made his discoveries we wouldn’t know the Earth isn’t the center of the universe, we wouldn’t have a pendulum, or the pendulum clock, and finally we would know little about the solar system.
  8. 8. THANKS FOR WATCHING!  Posy, Kathy, and Arlene
