Astronomy affords the most extensive example of the connection of physical sciences. In it are combined the sciences of number and quantity, or rest and motion. In it we perceive the operation of a force which is mixed up with everything that exists in the heavens or on earth; which pervades every atom, rules the…
I, Galileo Galilei, son of the late Vicenzio Galilei of Florence, aged seventy years, being brought personally to judgment, and kneeling before you.

Before there was an accurate seafaring clock, the sailor seeking his bearings had to be a trained mathematician. The accepted way to find longitude at sea was by precise observations of the moon, which required refined instruments and subtle calculations. An error as small as 5' in observing the moon meant an error of…
IN 1583 Galileo Galilei (1564–1642), a youth of nineteen attending prayers in the baptistery of the Cathedral of Pisa, was, according to tradition, distracted by the swinging of the altar lamp. No matter how wide the swing of the lamp, it seemed that the time it took the lamp to move from one end to the other was the…
The march of the sciences is rapid and brilliant. The Algebraic language becomes generalized, simplified and perfected, or rather it is now only that it was truly formed. The first foundations of the general theory of equations are laid, the nature of the solutions which they give is ascertained, and those of the…
History of science is a relay race, my painter friend. Copernicus took over his flag from Aristarchus, from Cicero, from Plutarch; and Galileo took that flag over from Copernicus.

After a duration of a thousand years, the power of astrology broke down when, with Copernicus, Kepler, and Galileo, the progress of astronomy overthrew the false hypothesis upon which the entire structure rested, namely the geocentric system of the universe. The fact that the earth revolves in space intervened to…
[P]olitical and social and scientific values … should be correlated in some relation of movement that could be expressed in mathematics, nor did one care in the least that all the world said it could not be done, or that one knew not enough mathematics even to figure a formula beyond the schoolboy s=(1/2)gt2. If…
A great many leading lights of the scientific revolution and the Enlightenment-Nicolaus Copernicus, Francis Bacon, Rene Descartes, Johannes Kepler, Galileo Galilei, Isaac Newton, Robert Boyle—were distinctly religious and viewed science as a better means of understanding God's creation and the laws governing it.
One had to be a Newton to see that the Moon is falling, when everyone sees that it doesn't. - Paul Valery
