As a formal concept, the method has variously been ascribed to Alhazen, René Descartes ( Discourse on the Method ) and Galileo Galilei.

Mainly Galileo Galilei ( 1564 – 1642 ) but also Marin Mersenne ( 1588 – 1648 ), independently, discovered the complete laws of vibrating strings ( completing what Pythagoras and Pythagoreans had started 2000 years earlier ).

* 1609 – Galileo Galilei demonstrates his first telescope to Venetian lawmakers.

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.

Later he claimed to be the discoverer of the moons, which led to a dispute with the true discoverer, Galileo Galilei.

* 1612 – Galileo Galilei becomes the first astronomer to observe the planet Neptune, although he mistakenly catalogued it as a fixed star.

Music and Science in the Age of Galileo Galilei ), arguably one of the most influential empiricists in history.

* 1564 – Galileo Galilei, Italian astronomer and physicist ( d. 1642 )

* 1633 – Galileo Galilei arrives in Rome for his trial before the Inquisition.

The Galilean moons are the four moons of Jupiter discovered by Galileo Galilei in January 1610.

Galileo Galilei, the discoverer of the four Galilean moons

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.

Actual proof of the Milky Way consisting of many stars came in 1610 when the Italian astronomer Galileo Galilei used a telescope to study the Milky Way and discovered that it is composed of a huge number of faint stars.

The € 20 billion project is named after the Italian astronomer Galileo Galilei.

Named after the Renaissance astronomer Galileo Galilei, it was launched on October 18, 1989, by the Space Shuttle Atlantis on the STS-34 mission.

* 1610: Galileo Galilei discovers the moons of Jupiter.

These works also influenced contemporary Italian scientist Galileo Galilei and provided one of the foundations for Englishman Isaac Newton's theory of universal gravitation.

It remained the mainstream scientific paradigm in Europe until the time of Galileo Galilei and Isaac Newton.

Galileo Galilei ( 1564 – 1642 )

The Italian mathematician, astronomer, and physicist Galileo Galilei ( 1564 – 1642 ) was the central figure in the Scientific Revolution and famous for his support for Copernianism, his astronomical discoveries, and his improvement of the telescope.

Additionally, he did fundamental work in the field of optics, invented an improved version of the refracting telescope ( the Keplerian Telescope ), and mentioned the telescopic discoveries of his contemporary Galileo Galilei.

* 1633 – The Holy Office in Rome forces Galileo Galilei to recant his view that the Sun, not the Earth, is the center of the Universe.

* 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.

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.

Two central figures in the early modern age are Galileo Galilei and Isaac Newton.

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.

Following Galileo and Torricelli, in 1646 he refuted Aristotle's followers who insisted that nature abhors a vacuum.

The names that eventually prevailed were chosen by Simon Marius, who discovered the moons independently at the same time as Galileo: he named them at the suggestion of Johannes Kepler after lovers of the god Zeus ( the Greek equivalent of Jupiter ): Io, Europa, Ganymede and Callisto, in his Mundus Jovialis, published in 1614.

The first satellites bear the names of eleven-year-old Thijs from Belgium and nine-year-old Natalia from Bulgaria who are the first winners of the European Commission's Galileo children's drawing competition.

While Leonardo's experimentation followed clear scientific methods, a recent and exhaustive analysis of Leonardo as scientist by Frtijof Capra argues that Leonardo was a fundamentally different kind of scientist from Galileo, Newton and other scientists who followed him in that, as a Renaissance Man, his theorising and hypothesising integrated the arts and particularly painting.

The parabolic trajectory of projectiles was discovered experimentally by Galileo in the early 17th century, who performed experiments with balls rolling on inclined planes.

The concept emerged from the numerous great thinkers of that era who excelled in multiple fields of the arts and science, including Leonardo da Vinci, Michelangelo, Galileo Galilei, Nicolaus Copernicus, and Francis Bacon.

The Academy has its origins in the Accademia dei Lincei (" Academy of Lynxes ") established in Rome in 1603, under Pope Clement VIII by the learned Roman prince, Federico Cesi ( 1585 – 1630 ), who was a young botanist and naturalist, and which claimed Galileo Galilei as its president.

In the Galileo affair, the acceptance, from 1616 to 1757, of the Greek geocentric model ( Ptolemaic system ) by the Roman Catholic Church, and its consequent opposition to heliocentrism, was first called into question by the Catholic cleric Copernicus, and subsequently disproved conclusively by Galileo, who was persecuted for his minority view.

Many well-known historical figures who influenced Western science considered themselves Christian such as Copernicus, Galileo, Kepler, and Boyle.

In a letter to Galileo in 1610, he wrote, " Provide ships or sails adapted to the heavenly breezes, and there will be some who will brave even that void.

Galileo advertised the puzzle to other scientists, including Gaspar Berti who replicated it by building the first water barometer in Rome in 1639.

Rocket Ship Galileo is a science fiction novel by Robert A. Heinlein, published in 1947, about three teenagers who participate in a pioneering flight to the Moon.

They visited Italy in 1641 and remained in Florence during the winter of that year studying the " paradoxes of the great star-gazer " Galileo Galilei, who was elderly but still living in 1641.

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 ).

– Instead of using an eyepiece, as did Galileo who had to tilt the mirror to have easy access to the image, Mersenne introduced the revolutionary idea of a second mirror that would reflect the light coming from the first mirror.

At the time, such speculation was of a rather rarefied sort, and was limited to astronomers like Christiaan Huygens who wrote a book, Cosmotheoros ( 1698 ) considering the possibility of life on other planets ; or to philosophers like Campanella, who wrote in defense of Galileo.

In the early 16th century, the debate on the Earth's motion was continued by Al-Birjandi ( d. 1528 ), who in his analysis of what might occur if the Earth were rotating, develops a hypothesis similar to Galileo Galilei's notion of " circular inertia ", which he described in the following observational test:

It was not until Galileo Galilei observed the moons of Jupiter on January 7, 1610, and the phases of Venus in September, 1610 that the heliocentric model began to receive broad support among astronomers, who also came to accept the notion that the planets are individual worlds orbiting the Sun ( that is, that Earth is a planet and is one among several.

Losey had co-directed the original U. S. production of Galileo with the author himself as the other co-director ( and Charles Laughton, who had worked on the translation / adaptation, had had the lead role, taken in the film by Topol ).

By the end of the 1970s the gaps between issues were lengthening, and the title was finally sold to Galileo publisher Vincent McCaffrey, who brought out only a single issue in 1980.

They also demonstrated this theorem — the foundation of " The Law of Falling Bodies " — long before Galileo, who is generally credited with it.

While not attributing magnetism to attraction among the stars, Gilbert pointed out the motion of the skies was due to earth's rotation, and not the rotation of the spheres, 20 years before Galileo ( but 57 years after Copernicus who stated it openly in his work " De revolutionibus orbium coelestium " published in 1543 ) ( see external reference below ).
