Galileo's experiments into gravity refuted Aristotle Galileo was a hugely influential Italian astronomer, physicist and philosopher. Galileo Galilei was born on 15 February 1564 near Pisa, the son of a musician. He began to study medicine at the University of Pisa but changed to philosophy and mathematics. In 1589, he became professor of mathematics at Pisa. In 1592, he moved to become mathematics professor at the University of Padua, a position he held until 1610. During this time he worked on a variety of experiments, including the speed at which different objects fall, mechanics and pendulums. In 1609, Galileo heard about the invention of the telescope in Holland. Without having seen an example, he constructed a superior version and made many astronomical discoveries. These included mountains and valleys on the surface of the moon, sunspots, the four largest moons of the planet Jupiter and the phases of the planet Venus. His work on astronomy made him famous and he was appointed court mathematician in Florence. In 1614, Galileo was accused of heresy for his support of the Copernican theory that the sun was at the centre of the solar system. This was revolutionary at a time when most people believed the Earth was in this central position. In 1616, he was forbidden by the church from teaching or advocating these theories. In 1632, he was again condemned for heresy after his book 'Dialogue Concerning the Two Chief World Systems' was published. This set out the arguments fo...

(Franklin Institute) Galileo’s telescope anchors the exhibit “Galileo, the Medici and the Age of Astronomy,” which is at the Franklin Institute in Philadelphia until September 7, 2009. Though Galileo didn’t invent the telescope (Dutch opticians did), he improved upon it. The first telescope used a combination of two lenses within a tube, and it could magnify items by three times, but showed them upside down. But when Galileo constructed his own telescope in 1609, he added a third lens. His telescope magnified items by eight times and showed them right side up. Over the following years, Galileo built several telescopes, including one that would magnify items by a factor of 30. (Franklin Institute) At the center of this instrument sits a globe representing the earth. The bands around it pivot on a common center and illustrate the paths of the sun and moon, known planets and important stars. The device was invented sometime in the last few centuries before Christ, but the sphere became widely used in Europe by a thousand years ago. This armillary sphere dates to 1578. (Franklin Institute) This portable instrument had rings that could be lined up with the equator, the meridian (the plane that holds both the observer and the celestial poles, about which the earth appears to revolve) and various angles in relation to the celestial equator. With such information, the user could make astronomical measurements and tell time. (Franklin Institute) During the day, a person could tell ...

(1564-1642) Who Was Galileo? Galileo was an Italian astronomer, mathematician, physicist, philosopher and professor who made pioneering observations of nature with long-lasting implications for the study of physics. He also constructed a telescope and supported the Early Life Galileo Galilei was born in Pisa in the Duchy of Florence, Italy, on February 15, 1564. Galileo was the first of six children born to Vincenzo Galilei, a well-known musician and music theorist, and Giulia Ammannati. In 1574, the family moved to Florence, where Galileo started his formal education at the Camaldolese monastery in Vallombrosa. Education In 1583, Galileo entered the While at Pisa, Galileo was exposed to the At first, Galileo supported this view, like any other intellectual of his time, and was on track to be a university professor. However, due to financial difficulties, Galileo left the university in 1585 before earning his degree. Career as a Professor Galileo continued to study mathematics after leaving the university, supporting himself with minor teaching positions. During this time he began his two-decade study on objects in motion and published The Little Balance, describing the hydrostatic principles of weighing small quantities, which brought him some fame. This gained him a teaching post at the University of Pisa, in 1589. While there, Galileo conducted his fabled experiments with falling objects and produced his manuscript Du Motu (On Motion), a departure from Aristotelian view...

The thermoscope: One of Galileo Galilei’s most noteworthy inventions made around 1593, was the thermoscope, an earlier version of the thermometer. The thermoscope was a device built from a small vase filled with water, attached to a thin vertically rising pipe, with a large empty glass ball at the top. The telescope: Although the telescope was invented by German-Dutch spectacle-maker Hans Lippershey in 1608, Galileo made a version based on descriptions Lippershey’s invention the following year in 1609. Intially capable of about 3x magnification, Galileo later made improved versions with up to about 30x magnification. The phases of Venus: Galileo observed that Venus exhibited a full set of phases similar to that of the Moon in September 1610. Nicolaus Copernicus’ heliocentric model of the solar system predicted that all phases would be visible since the...

Galileo Galilei (1564-1642) is considered the father of modern science and made major contributions to the fields of physics, astronomy, cosmology, mathematics and philosophy. Galileo invented an improved telescope that let him observe and describe the moons of Jupiter, the rings of Saturn, the phases of Venus, sunspots and the rugged lunar surface. His flair for self-promotion earned him powerful friends among Italy’s ruling elite and enemies among the Catholic Church’s leaders. Galileo’s advocacy of a heliocentric universe brought him before religious authorities in 1616 and again in 1633, when he was forced to recant and placed under house arrest for the rest of his life. Galileo’s Early Life, Education and Experiments Galileo Galilei was born in Pisa in 1564, the first of six children of Vincenzo Galilei, a musician and scholar. In 1581 he entered the University of Pisa at age 16 to study medicine, but was soon sidetracked by mathematics. He left without finishing his degree. In 1583 he made his first important discovery, describing the rules that govern the motion of pendulums. Did you know? After being forced during his trial to admit that the Earth was the stationary center of the universe, Galileo allegedly muttered, "Eppur si muove!" ("Yet it moves!" ). The first direct attribution of the quote to Galileo dates to 125 years after the trial, though it appears on a wall behind him in a 1634 Spanish painting commissioned by one of Galileo's friends. From 1589 to 1610...

Inside a glass case was a plain-looking tube, worn and scuffed. Lying in the street, it would have looked like a length of old pipe. But as I approached it, Derrick Pitts—only half in jest—commanded: "Bow down!" The unremarkable-looking object is in fact one of the most important artifacts in the history of science: it's one of only two surviving telescopes known to have been made by Galileo Galilei, the man who helped revolutionize our conception of the universe. The telescope was the centerpiece of "Galileo, the Medici and the Age of Astronomy," an exhibition at the Franklin Institute in Philadelphia in 2009. Pitts, who runs the institute's planetarium and other astronomy programs, says that receiving the telescope from Florence's Galileo Museum—the first time the instrument ever left Florence—was "something of a religious experience." Understandably so: if Galileo is considered a patron saint of astronomy, then his telescope is one of its most holy relics. "Galileo's work with the telescope unleashed the notion that ours is a sun-centered solar system and not an Earth-centered solar system," says Pitts. In other words, from that ugly old cylinder came the profound idea that we are not the center of the universe. It was a dangerous idea, and one that cost Galileo his freedom. On a starry night in Padua 400 years ago, Galileo first turned a telescope toward the sky. It might seem the most natural of actions—after all,what else does one do with a telescope? But in 1609, th...

1. He was a college dropout. Galileo, whose father was a lute player and music theorist, was born in Pisa, Italy. Although his father was from a noble family, they weren’t wealthy. As a pre-teen, Galileo began studying at a monastery near Florence and considered becoming a monk; however, his father wasn’t in favor of his son pursuing a religious life and eventually removed him from school. When he was 16, Galileo enrolled at the University of Pisa to study medicine, at his father’s urging. Instead, though, he became interested in mathematics and shifted his focus to that subject. Galileo left the school in 1585 without earning a degree. He continued his mathematics studies on his own and earned money by giving private lessons before returning to the University of Pisa in 1589 to teach math. 2. He didn’t invent the telescope. Galileo didn’t invent the telescope—Dutch eyeglass maker Hans Lippershey is generally credited with its creation—but he was the first person to use the optical instrument to systematically study the heavens. Lippershey’s patent application for the device in 1608 is the earliest on record; however, because the Dutch government decided the telescope was too easy to copy and because another Dutch instrument maker had tried to patent the device a short time after Lippershey, no patent was granted. In 1609, Galileo learned about the device and developed one of his own, significantly improving its design. That fall, he pointed it at the moon and discovered i...

Galileo is considered one of the greatest astronomers of all time. His discovery of Jupiter’s major moons (Io, Europa, Ganymede and Callisto) revolutionized astronomy and helped speed the acceptance of the Copernican Model of the universe. However, Galileo is also known for the numerous scientific inventions he made during his lifetime. These included his famous telescope, but also a series of devices that would have a profound impact on surveying, the use of artillery, the development of clocks, and meteorology. Galileo created many of these in order to earn extra money to support his family. But ultimately, they would help cement his reputation as the man who challenged centuries worth of previously-held notions and revolutionized the sciences. Hydrostatic Balance: Inspired by the story of Archimedes’ and his “Eureka” moment, Galileo began looking into how jewelers weighed precious metals in air, and then by displacement, to determine their specific gravity. In 1586, at the age of 22, he theorized of a better method, which he described in a treatise entitled La Bilancetta (or “The Little Balance”).
