Said to have set the scientific revolution in motion. in 1593 he devised a simple thermometer. in 1602 he discovered the isochronism of the pendulum. 1604 he worked out law of falling bodies. 1609 he constructed improved refracting telescope; first to turn telescope to celestial bodies. 1611 he discovered the phases of saturn and sunspots. 1618 he was involved in controversy about comets. 1637 he discovered librations of the moon.Sentenced to life on house arrest. He also went blind in 1637. 1641 he worked on application of pendulum to regulation of clock mechanics. He died in 1642 in Arcetri, near florence.

Galileo was born in Pisa, Italy on February 15, 1564. His father, Vincenzo Galilei, was a musician. Galileo's mother was Giulia degli Ammannati. Galileo was the first of six (though some people believe seven) children. His family belonged to the nobility but was not rich. In the early 1570's, he and his family moved to Florence. While at the University of Pisa, Galileo began his study of the pendulum while, according to legend, he watched a suspended lamp swing back and forth in the cathedral of Pisa. He discovered that the period (the time in which a pendulum swings back and forth) does not depend on the arc of the swing (the isochronism).At the University of Pisa, Galileo learned the physics of the Ancient Greek scientist, Aristotle. However, Galileo questioned the Aristotelian approach to physics. Aristotelians believed that heavier objects fall faster through a medium than lighter ones. Galileo eventually disproved this idea by asserting that all objects, regardless of their density, fall at the same rate in a vacuum. To determine this, Galileo performed various experiments in which he dropped objects from a certain height. In one of his early experiments, he rolled balls down a gently sloping inclined plane and then determined their positions after equal time intervals. He wrote down his discoveries about motion in his book, De Motu, which means "On Motion." perhaps his most famous invention was the telescope. Galileo made his first telescope in 1609, modeled after telescopes produced in other parts of Europe that could magnify objects three times. He created a telescope later that same year that could magnify objects twenty times. With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. Van Helden, A (1995).

 * Galileo Galilei** was born on February 15, 1564 in Pisa, Italy. Galileo pioneered "experimental scientific method" and was the first to use a refracting telescope to make important astronomical discoveries.

Galileo's originality as a scientist lay in his method of inquiry. First he reduced problems to a simple set of terms on the basis of everyday experience and common-sense logic. Then he analyzed and resolved them according to simple mathematical descriptions. The success with which he applied this technique to the analysis of motion opened the way for modern mathematical and experimental physics. Isaac Newton used one of Galileo's mathematical descriptions, "The Law of Inertia," as the foundation for his "First Law of Motion."

Galileo became blind at the age of 72. His blindness has often been attributed to damage done to his eyes by telescopic observations he made of the Sun in 1613. The truth is he was blinded by a combination of cataracts and glaucoma. Galileo died at Arcetri in 1642—the year Isaac Newton was born. ( 2008). Galileo Galilei.

A mathmaticion, physisist, and astronomer, Galileo Galilei rejected the accepted truths of his time and substituted his own. He is said to have set the scientific revolution in motion. He made many discoveries and invented many usefull devices whos technology was much more advanced for his time.

This is a recreation of an interview that would have been held with Galileo himself:

Me: Hello, how are u doing today. GG: Im doing fine, thanks for asking. Me: Now we are at your house right now because your not allowed to leave it. Can you tell us a little more about that GG: Sure. I was sentenced to a life of house arrest by the Catholic Inquisition. Me: And what were the Charges? GG: I was tried as a heretic for my support of the Heliocentric theory of Copernicus. Me: could you explain that in simpilar terms? GG: Well it basically states that the Sun is the center of the universe rather than the Earth. The Church's doctrine states that the Sun rotates around the Earth. But I have good reason to believe that they are wrong. Me: And why do you think this theory is accurate? GG: I have witnessed it with my own eyes. Through my telescope. Me Yes your telescope. Can you tell us more about this invention of yours? GG: My telescope is now made with 30 times the magnification of the original Dutch telescope. But it took alot of time to perfect it. My first model only magnified 3x. Me: it seems like you worked hard on it. GG: Oh yes. But without it I couldn't have made the many discoveries that i have. Me: You certainly have made tremendous leaps in Astronomy. Could you tell us about some of your other discoveries? GG: In 1610 I discovered three moons orbiting the planet Jupiter. Then in the same year I observed the phases of Saturn. Me: Wow that is very impresive for one man to accomplish within a year. GG: I also became very interested in comets in 1619. But all of my work with astronomy just got me into trouble with the church. Me: It doesn't seem fair for you to be punished for making discoveries that advanced human thinking about the universe. GG: yes, I think its a little strange that the man that spends most of his time looking up at the heavens trying to learn about them is deemed unholy and evil. Me. Great point. You also have made many other contributions in the scientific community can you tell me about some of those? GG. My first scientific invention was a simple thermometer. Later on I woked with the Isosynchronism of the pendulum and eventually applied my findings to clock mechanics. In 1604 I preformed the famed experiment in which I dropped two balls of different masses out of my window to prove that all objects fall at the same rate in a vacuum. Me: You truely have the most impresive scientific resume of any person I know of. GG: Thank You Me: Now that we have heard about your scientific career, lets talk about you early life and your family. GG: OK Me: Where did You grow up? GG: I was born on Febuary 15, 1564 in the city of Pisa Italy. Me: Tell me about your parents. GG: My father was a musician named Vincenzo Galilei and my mother's name was Giulia Ammannati. Me: And your family was part of the nobility right? GG: Yes but we were not very wealthy. Me: Did you have any brothers or sisters? GG: Yes, Actually i was the first of 6 children Me: That sounds like a pretty hectic household. How did you end up here in Arcetri? GG: In 1570 my family moved to Florence then i studied at the University of Pisa. Shortly after my time at the University i moved here to Acetri, where i will be for the rest of my life. Me. Sir, I have truly enjoyed talking with you. Your lifes work is truely amazing. GG: Thank you for having me.

Galileo died in 1642- the same year Issac Newton was born
