" The Four Books on Measurement " were published at Nuremberg in 1525 and was the first book for adults on mathematics in German, as well as being cited later by Galileo and Kepler.

Although observations of some aerodynamic effects such as wind resistance ( e. g. drag ) were recorded by Aristotle, Leonardo da Vinci and Galileo Galilei, very little effort was made to develop a rigorous quantitative theory of air flow prior to the 17th century.

< cite id = disputedinjunction > The Vatican archives contain an unsigned copy of a more strongly worded formal injunction purporting to have been served on Galileo shortly after Bellarmine's admonition, ordering him " not to hold, teach, or defend " the condemned doctrine " in any way whatever, either orally or in writing ", and threatening him with imprisonment if he refused to obey .</ cite > However, whether this injunction was ever properly served on Galileo is a subject of much scholarly disagreement.

While the impacts took place on the side of Jupiter hidden from Earth, Galileo, then at a distance of 1. 6 AU from the planet, was able to see the impacts as they occurred.

A few minutes after the impact fireball was detected, Galileo measured renewed heating, probably due to ejected material falling back onto the planet.

It is often said that Galileo thought the curve of a hanging chain was parabolic.

* 1995 – The Galileo spacecraft arrives at Jupiter, a little more than six years after it was launched by Space Shuttle Atlantis during Mission STS-34.

The work of Copernicus, Kepler, and Galileo set aside the old notion that the earth was the center of the universe.

Through such people as Nikola Tesla, Galileo Ferraris, Oliver Heaviside, Thomas Edison, Ottó Bláthy, Ányos Jedlik, Sir Charles Parsons, Joseph Swan, George Westinghouse, Ernst Werner von Siemens, Alexander Graham Bell and Lord Kelvin, electricity was turned from a scientific curiosity into an essential tool for modern life, becoming a driving force for the Second Industrial Revolution.

It is known that he was the essential pedagogical influence upon the young Galileo, his eldest son ( cf.

As a result of improvements Galileo Galilei made to the telescope, with a magnifying capability of 20 ×, he was able to see celestial bodies more distinctly than was ever possible before.

As a result of these discoveries, Galileo was able to develop a method of determining longitude based on the timing of the orbits of the Galilean moons.

The first stage of the Galileo programme was agreed upon officially on 26 May 2003 by the European Union and the European Space Agency.

Although a decision was yet to be reached, on 13 July 2007 EU countries discussed cutting € 548m ($ 755m, £ 370m ) from the union's competitiveness budget for the following year and shifting some of that cash to other parts of the financing pot, a move that could meet part of the cost of the union's Galileo satellite navigation system.

In November 2009, a ground station for Galileo was inaugurated near Kourou ( French Guiana ).

As of March 2010 it was verified that the budget for Galileo would only be available to provide the 4 IOV and 14 FOC satellites by 2014, with no funds currently committed to bring the constellation above this 60 % capacity.

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.

This greatly improves the viability of the Galileo project: " The EU's executive had previously said that if agreement was not reached by January 2008, the long-troubled project would essentially be dead.

A primary motivation for the Galileo project was European concern that the US could deny others access to GPS during political disagreements.

Since Galileo was designed to provide the highest possible precision ( possibly even greater than GPS ) to anyone, the US was concerned that an enemy could use Galileo signals in military strikes against the US and its allies ( some weapons like missiles use GNSS systems for guidance ).

The Copernican theory of the solar system – that the Earth revolved annually about the Sun – had received confirmation by the observations of Galileo and Tycho Brahe ( who, however, never accepted heliocentrism ), and the mathematical investigations of Kepler and Newton.

Galileo used this system in his notebooks but never actually published it.

In 1612, Galileo Galilei proposed that with sufficiently accurate knowledge of the orbits of the moons of Jupiter one could use their positions as a universal clock and this would make possible the determination of longitude, but the practical problems of the method he devised were severe and it was never used at sea.

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

Galileo never took Tycho's system seriously, as can be seen in his correspondence, regarding it as an inadequate and physically unsatisfactory compromise.

After the Galileo affair, which transpired early in the 17th century, Copernicanism was never officially forbidden to astronomers in the Roman Catholic Church but the Tychonic system was an acceptable alternative that matched available observations, the Copernican system having more epicycles even than the Ptolemaic.

" In response to an enquiry about the same sermon from the botanist Henry Nicholas Ridley, Darwin stated that " Dr Pusey was mistaken in imagining that I wrote the Origin with any relation whatever to Theology ", and added that " many years ago when I was collecting facts for the Origin, my belief in what is called a personal God was as firm as that of Dr Pusey himself, & as to the eternity of matter I have never troubled myself about such insoluble questions .— Dr Pusey's attack will be as powerless to retard by a day the belief in evolution as were the virulent attacks made by divines fifty years ago against Geology, & the still older ones of the Catholic church against Galileo ".

Galileo says that he true and real motion of the stone is never accelerated at all, but is always equable and uniform ....

Anyway a really exceptional event happened during the winter of 1608: a snowfall that lasted for 40 consecutive days, from late January to early March, with the snow depth at ground reaching at least 6-7ft ( about 2m ) as witnessed by Galileo ; a similar event never repeated.

In his 1619 request for this, Galileo declared that at the time of his cohabitation with Marina, she " had never been married " and was " already dead " at the drawing up of the act.

Saturn Rings: Focus of the Cimento, but never publishedGiorgio Strano argues that the members of the Cimento, especially Galileo ’ s students, continued to use a deductive approach using ancient texts to drive their selection of experiments and how the experiments were conducted.

The Italian Catholic Galileo Galilei ( 1564 – 1642 ), one of the foremost promoters of the new philosophy, insisted that nature " never violates the terms of the laws imposed upon her.

Using a telescope, Galileo was able to observe Venus going through a full set of phases, something prohibited by the Ptolemaic system ( which would never allow Venus to be fully lit from the perspective of the Earth or more than semi-circular ).

NASA engineers were able to recover the damaged tape recorder electronics, and Galileo continued to return scientific data until it was deorbited in 2003, performing one last scientific experiment — a measurement of the moon Amalthea's mass as the spacecraft swung by it.

* 1610 – Galileo Galilei makes his first observation of the four Galilean moons: Ganymede, Callisto, Io and Europa, although he is not able distinguish the last two until the following day.

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.

For example, Galileo Galilei was able to accurately measure time and experiment to make accurate measurements and conclusions about the speed of a falling body. Antoine Lavoisier was a French chemist in the late 1700s who used experiment to describe new areas such as combustion and biochemistry and to develop the theory of conservation of mass ( matter ).

Nevertheless, by anticipating the existence of the vacuum, later to be demonstrated on Earth by his collaborator Evangelista Torricelli, Galileo was able to initiate the future science of mechanics.

In the 17th century AD Galileo Galilei opposed the Roman Catholic Church by his strong support for heliocentrismGalileo was able to look at the night sky with the newly invented telescope.

Galileo worked on an additional section on the force of percussion, but was not able to complete it to his own satisfaction.

Galileo Galilei first described this principle in 1632 in his Dialogue Concerning the Two Chief World Systems using the example of a ship travelling at constant velocity, without rocking, on a smooth sea ; any observer doing experiments below the deck would not be able to tell whether the ship was moving or stationary.

Galileo was the first to observe the Beehive in a telescope, in 1609, and was able to resolve it into 40 stars.

As a result of his study of Aristotle, and in particular Question 4 regarding the propulsion of ships by oar, Galileo was able to produce a response to this question and ended up becoming a major source of information for the shipbuilders of the Arsenal concerning matters of rowing, instruments, and ballistics.

The receivers will be able to combine the signals from both Galileo and GPS satellites to greatly increase the accuracy.

The European scientists Cornelius Drebbel, Robert Fludd, Galileo Galilei and Santorio Santorio in the 16th and 17th centuries were able to gauge the relative " coldness " or " hotness " of air, using a rudimentary air thermometer ( or thermoscope ).
