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.

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.

Nicolaus Copernicus ( 1473 – 1543 ), Kepler ( 1571 – 1630 ), Newton ( 1642 – 1727 ) and Galileo Galilei ( 1564 – 1642 ) all traced different ancient and medieval ancestries for the heliocentric system.

" And yet it moves " (; ) is a phrase said to have been uttered before the Inquisition by the Italian mathematician, physicist and philosopher Galileo Galilei ( 1564 – 1642 ) in 1633 after being forced to recant his belief that the earth moves around the sun.

The monument is a large outdoor concrete sculpture on the front lawn that pays homage to six of the greatest astronomers of all time: Hipparchus ( about 150 BC ); Nicholas Copernicus ( 1473 – 1543 ); Galileo Galilei ( 1564 – 1642 ); Johannes Kepler ( 1571 – 1630 ); Isaac Newton ( 1642 – 1727 ); and William Herschel ( 1738 – 1822 ).

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.

( Blackwell, 1991, p. 127 – 128 ) Galileo agreed.

1520 – 1591 ), father of Galileo and the inventor of monody, made use of the method in successfully solving musical problems, firstly, of tuning such as the relationship of pitch to string tension and mass in stringed instruments, and to volume of air in wind instruments ; and secondly to composition, by his various suggestions to composers in his Dialogo della musica antica e moderna ( Florence, 1581 ).
