Galileo ’ s discovery showed the importance of the telescope as a tool for astronomers by proving that there were objects in space that cannot be seen by the naked eye.

On January 7, 1610, Galileo wrote a letter containing the first mention of Jupiter ’ s moons.

Galileo, seeking patronage from his now-wealthy former student and his powerful family, used the discovery of Jupiter ’ s moons to gain it.

On February 13, 1610, Galileo wrote to the Grand Duke ’ s secretary:

On March 12, 1610, Galileo wrote his dedicatory letter to the Duke of Tuscany, and the next day sent a copy to the Grand Duke, hoping to obtain the Grand Duke ’ s support as quickly as possible.

When Galileo was viewed as a private-sector development with public-sector financial participation, European Commission program managers sought Chinese participation in pursuit of Chinese cash in the short term and privileged access to China ’ s market for positioning and timing applications in the longer term.

However, due to security and technology-independence policy from European Commission, China was, in effect, dis-invited from Galileo and without a return of its monetary investment, a decision that was reinforced by China ’ s move to build its own global system, called Beidou / Compass.

At the Munich Satellite Navigation Summit on March 10, a Chinese government official asked the European Commission why it no longer wanted to work with China, and when China ’ s cash investment in Galileo would be returned.

* Tommaso Campanella ’ s book In Defence of Galileo is written.

He was able to use his new analytical method to replace that of Aristotle, and he was able to use his method to tweak and update Galileo ’ s experimental method.

The re-creation of Galileo ’ s method has never been significantly changed and in its substance, scientists use it today.

Theoretical reduction is the process by which one theory is absorbed into another ; for example, both Kepler's laws of the motion of the planets and Galileo ’ s theories of motion worked out for terrestrial objects are reducible to Newtonian theories of mechanics, because all the explanatory power of the former are contained within the latter.

Gersonides was also the earliest known mathematician to have used the technique of mathematical induction in a systematic and self-conscious fashion and anticipated Galileo ’ s error theory.

On October 21, 2011 two Galileo IOV-1 & IOV-2 satellites were launched using a Soyuz-ST rocket, in the " first Russian Soyuz vehicle ever launched from Europe ’ s Spaceport in French Guiana.

Galileo ’ s best telescope magnified objects about 30 times.

Galileo Galilei ’ s rejection of Aristotle ’ s law of gravity was based on a case study selected by information-oriented sampling and not random sampling.

Galileo ’ s experimentalism did not involve a large random sample of trials of objects falling from a wide range of randomly selected heights under varying wind conditions, and so on.

Galileo ’ s view continued to be subjected to doubt, however, and the Aristotelian view was not finally rejected until half a century later, with the invention of the air pump.

One might call it a critical case, for if Galileo ’ s thesis held for these materials, it could be expected to be valid for all or a large range of materials.

His work, and the work of many others, however, may still have been influenced by the Holy Office ’ s treatment of his contemporary Galileo Galilei.

For Galileo ’ s son of the same name, see Vincenzo Gamba.

This jump in observational power — comparable to the step in sensitivity from the unaided eye to Galileo ’ s first telescope — will reveal vast numbers of new objects and allow the creation of far more complete inventories of rare and exotic objects in the southern sky.

At the time, Travelport included the Orbitz travel reservation website used by consumers, the Galileo computer reservations system used by airlines and thousands of travel agents, Gulliver ’ s Travels and Associates wholesale travel business, and numerous other travel related software brands and solutions.

Instruments on Galileo detected a fireball which reached a peak temperature of about 24, 000 K, compared to the typical Jovian cloudtop temperature of about 130 K, before expanding and cooling rapidly to about 1500 K after 40 s. The plume from the fireball quickly reached a height of over 3, 000 km.

Galileo < nowiki >'</ nowiki > s prime mission was a two-year study of the Jovian system.

Once Galileo < nowiki >'</ nowiki > s prime mission was concluded, an extended mission followed, starting on December 7, 1997 ; the spacecraft made a number of daring close flybys of Jupiter's moons Europa and Io.

Galileo announced his discovery that Venus had phases like the Moon in the form " Haec immatura a me iam frustra leguntur-oy " ( Latin: These immature ones have already been read in vain by me-oy ), that is, when rearranged, " Cynthiae figuras aemulatur Mater Amorum " ( Latin: The Mother of Loves Venus imitates the figures of Cynthia the moon ).

Galileo initially named his discovery the Cosmica Sidera (" Cosimo's stars "), but names that eventually prevailed were chosen by Simon Marius.

Galileo initially called his discovery the Cosmica Sidera (" Cosimo's stars "), in honour of Cosimo II de ' Medici ( 1590 – 1621 ).

From its discovery around 1602 by Galileo Galilei the regular motion of pendulums was used for timekeeping, and was the world's most accurate timekeeping technology until the 1930s.

It was the last planetary satellite to be discovered by direct visual observation ( as opposed to photographically ) and was the first new satellite of Jupiter since Galileo Galilei's discovery of the Galilean satellites in 1610.

This was a method sometimes used by scientists, such as Hooke, Huygens, Galileo, and others, to establish priority for a discovery without revealing details.

* Galileo – 18 October 1989 – Venus flyby, first Asteroid flyby, first Asteroid moon discovery, first Jupiter orbiter / atmospheric probe

In the last portion of Sidereus Nuncius, Galileo reported his discovery of four objects that appeared to form a straight line of stars near Jupiter.

The discovery of the rotating magnetic field is generally attributed to two inventors, the Italian physicist and electrical engineer Galileo Ferraris, and the Austrian / Serbian inventor and electrical engineer Nikola Tesla.

Galileo Galilei has been called the " father of modern observational astronomy ", because of his discovery of telescope and heliocentrism, and even " the Father of Modern Science ".

The Roman numbering system arose with the very first discovery of natural satellites other than Earth's Moon: Galileo referred to the Galilean moons as I through IV ( counting from Jupiter outward ), in part to spite his rival Simon Marius, who had proposed the names now adopted, after his own proposal to name the bodies after members of the Medici family failed to win currency.

Other famous scientists that have been depicted include Alessandro Volta ( the battery ) and Galileo ( the telescope and his discovery of Jupiter's largest moons ).

Given that Galileo published his work before Marius, Galileo is credited with the discovery.

In a debate about Galileo ’ s discovery of the Rings of Saturn these members developed an experiment which would demonstrate that Galileo ’ s discovery was validated by Christiaan Huygens theory.

Galileo Ferraris ( 31 October 1847 – 7 February 1897 ) was an Italian physicist and electrical engineer, noted mostly for the studies and independent discovery of the rotating magnetic field, a basic working principle of the induction motor.

The historian Xi Zezong has claimed that this was a naked-eye observation of Ganymede in the summer of 365 BC, long before Galileo Galilei's celebrated discovery of the same in 1610 ( all four of the brightest moons are technically visible to the unaided eye, but in practice are normally hidden by the glare of Jupiter ).

And I guess one of the reasons we got here today was because of a gentleman named Galileo, a long time ago, who made a rather significant discovery about falling objects in gravity fields.
