... Galilei ( 1564–1642 ) Italian scientist . Although Galileo’s distinction belongs to the history of physics and astronomy rather than philosophy, his mature philosophy and methodology of science, particularly as derived from the Dialogue Concerning the Two Chief World Systems ( 1632 ) and the Dialogues Concerning Two New Sciences ( 1638 ), have been much debated. Galileo unquestionably holds that science based on observation is the true source of knowledge of the physical world, as opposed to traditional authority and philosophical speculation. He...

... Galilei ( 1564–1642 ) Italian mathematician , astronomer and physicist who established the method of studying dynamics by a combination of theory and experiment. He formulated and verified by experiment the law of uniform acceleration for falling bodies, and derived the parabolic path of a projectile. He developed the telescope and was the first to use it to make significant and outstanding astronomical observations. In later life, his support for the Copernican theory that the planets travel round the Sun resulted in conflict with the Church...

... Galilei ( 1564–1642 ) Italian astronomer , physicist , and mathematician . In 1609 he heard of the recent invention of the telescope, and began to make his own. He built several small refractors, up to 50 mm aperture, the highest magnification being about × 30. He published Sidereus nuncius (‘Starry Messenger’) in 1610 , in which he outlined his early telescopic discoveries, including mountains on the Moon, the four satellites of Jupiter (known as the Galilean satellites ), and the innumerable stars of the Milky Way. Also in 1610 he observed...

... Galilei ( 1564–1642 ) Italian astronomer and physicist , born in Pisa of a Florentine family. In 1604 he demonstrated that unequal weights drop with equal velocity, an observation apocryphally said to be based on the dropping of weights from the leaning Tower of Pisa. In 1609 he assembled a telescope on the basis of reports of such an instrument in the Netherlands, and so discovered the moons of Jupiter, the phases of Venus, the configuration of the moon, and the stars invisible to the naked eye, all of which were described in Sidereus Nuncius ...

... Galilei ( 1564–1642 ). Galileo was an astronomer and physicist whose influence on the development of scientific and philosophical thought can hardly be overstated. No retiring scholar but a controversialist at home in the leading universities and palaces of Renaissance Italy until condemned by the Roman Inquisition, Galileo opposed by both word and deed the imposition of authority on the study of natural phenomena, and supported freedom of inquiry and expression. In opposition to Aristotelianism , Galileo insisted that mathematics was at the heart of...

..., Galileo ( 1564–1642 ), mathematician and scientist , usually known as ‘Galileo’. As professor of mathematics at Pisa and then Padua, he developed ideas on a new science of motion that can be seen as leading to Newtonian physics. In 1609 he heard of a new instrument (later known as the telescope) and embarked on a systematic observation of the heavens; he used the results in works published in 1610 and 1613 to support a heliocentric Copernican cosmology. In 1610 he moved to Florence. Soon the theological significance of Copernicanism for...

..., Galileo ( 1564–1642 ), Usually known simply by his given name, Italian mathematician and natural philosopher and astronomer. He was born in Pisa into a family that had been established in Florence for several generations; this is the meaning of the phrase gentiluomo fiorentino which his father Vincenzo uses to describe himself. In 1581 Galileo entered the University of Pisa, but left in 1585 and continued study of mathematics and natural philosophy in private. It may have been at this time that he began to reflect on the possibility that all...

...Galileo Galilei ( 1564–1642 ) Italian astronomer and physicist . In 1583 he noticed that the time of swing of a pendulum is independent of its amplitude, and three years later invented a hydrostatic balance for measuring relative densities . He became a professor in Padua in 1592 and it was there (in 1609 ) that he made his first astronomical telescope. With it he discovered four satellites of Jupiter, mountains on the moon, and sunspots. Returning to Pisa, his birthplace, he studied motion, demonstrating that the speed of a falling body is independent...

...Galilei, Galileo ( 1564–1642 ) An Italian scientist noted for his experiments and studies on gases, dynamics, and temperature measurement. He studied medicine at the University of Pisa aged 17. At the cathedral in Pisa, he timed the swinging lamp with his pulse and found that the oscillations took equal times. This discovery led to the development of the pendulum clock. He became professor of mathematics at Padua and studied dynamics. It is said that he demonstrated from the Leaning Tower of Pisa that bodies of different weights fell with the same ...

...Galileo Galilei 1564 1642 Italian astronomer and physicist Eppur si muove [But it does move]. Muttered comment after his recantation of the theory that the earth moves around the sun, probably in 1633. First reported in Giuseppe Baretti, The Italian Library (1757), the remark seems most unlikely ever to have passed Galileo's lips. Baretti reports that ‘the celebrated Galileo , who was in the inquisition for six years, and put to the torture, for saying, the earth moved . The moment he was set at liberty, he looked up to the sky and down to the...

In Letter to the Grand Duchess Christina (mother of Cosimo II) Galileo stated that a figurative interpretation of the Scriptures was necessary because physical reality demonstrated that the sun was the center of the universe. Galileo was entering the theological domain at a time when the Counter-Reformation was at its height and the reigning pope, Paul V (papacy 1605–1621 ), was hostile to new ideas.
