The audience files into the theatre taking their seats around — and in fact on — the circular stage. Electronic music, written by Tom Rowlands of Chemical Brothers fame, blares through the speakers as the actors dance around, pumping up the audience. A short puppet show sets the stage and we find Galileo in his house discussing with Andrea, his housekeeper’s son and trusted student, Copernicus’s heliocentric system. Soon thereafter Galileo builds his first telescope, following news of such a contraption being sold in the Netherlands, and it’s not much later that he points it to the sky. At that moment, the planetarium-like screen overhanging the stage lights up with a starry night sky and then the Moon with its many craters, valleys and mountains.

Galileo studied speed and velocity , gravity and free fall , the principle of relativity , inertia , projectile motion and also worked in applied science and technology, describing the properties of pendulums and ” hydrostatic balances”, inventing the thermoscope and various military compasses , and using the telescope for scientific observations of celestial objects. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus , the observation of the four largest satellites of Jupiter , the observation of Saturn’s rings , and the analysis of sunspots.

Galileo’s championing of heliocentrism and Copernicanism met with opposition from within the Catholic Church and from some astronomers.

British Broadcasting Corporation Home. Galileo Galilei was born on 15 February near Pisa, the son of a musician. He began to study medicine at the University of Pisa but changed to philosophy and mathematics. In , he became professor of mathematics at Pisa. In , he moved to become mathematics professor at the University of Padua, a position he held until During this time he worked on a variety of experiments, including the speed at which different objects fall, mechanics and pendulums.

In , 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 , 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.

The complete system consists of:. The first two IOV satellites were launched on Oct. It includes an initial operational capability phase of 18 operational satellites. The full system will consist of 30 satellites, control centers located in Europe and a network of sensor stations and uplink stations installed around the globe.

Political decisions made by the European Parliament and the Council in resulted in the allocation of a budget for the European satellite navigation programs EGNOS and Galileo and provided for an agreement on the governance structure of the programs. This framework provides for the deployment of the FOC Full Operational Capability of Galileo under a public procurement scheme, entirely financed out of the European Community budget.

The probe had to withstand extreme heat and pressure on its high-speed journey at , miles per hour. The deceleration module consisted.

Galileo Galilei

Between and , [1] the Italian scientist Galileo Galilei then professor of mathematics at the University of Pisa is said to have dropped two spheres of different masses from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass, according to a biography by Galileo’s pupil Vincenzo Viviani , composed in and published in According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle ‘s theory of gravity which states that objects fall at speed proportional to their mass.

Most historians consider it to have been a thought experiment rather than a physical test. At the time when Viviani asserts that the experiment took place, Galileo had not yet formulated the final version of his law of free fall. He had, however, formulated an earlier version which predicted that bodies of the same material falling through the same medium would fall at the same speed.
