Quotes About Galileo

Y sin embargo, se mueve! (Eppur si muove)

One of the things that always fascinated me about the Renaissance was that it was a time both of great scientific discovery and also of superstition and belief in magic. And so it was a period in which Galileo invented the telescope, but also a time when hundreds were burned at the stake because people thought they were witches.

Galileo was no idiot. Only an idiot could believe that science requires martyrdom - that may be necessary in religion, but in time a scientific result will establish itself.

Galileo died in 1642. He was buried in Florence in the Church of Santa Croce, directly opposite the tomb of Michelangelo. This is only right, since together they had remade the Renaissance world in a distinctly Platonist frame.

Isaac Newton was hardly the person people would pick to be the cultural guru of his age. Everyone recognized that this son of a clergyman from northwestern England (born the same year Galileo died, in 1642) was an incredible math prodigy.

privately Galileo thought the condemnation of Copernicus was wrong. "The Bible tells us how to go to Heaven," he once quipped, "not how the heavens go.

There is no event in Nature," Galileo wrote, "such that it will be completely understood by theorists."36 God's perfection was to be found in the numbers, not in the shapes or objects. Yet without real objects, the math can become an exercise in pure speculation or even hallucination, as Giordano Bruno's life revealed.

Galileo's science managed to fuse the Platonist's faith in mathematics with the Aristotelian faith in experience as the basis of discovery. All his work on mechanics, optics, and astronomy was deeply rooted in experiment and empirical research. When experience proved ambiguous or unreliable, however, Galileo realized then that mathematics must take over.

The universe, Galileo wrote, "is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures, without which it is humanly impossible to understand a single world of it." Without mathematics, he concluded, "one wanders about in a dark labyrinth"—or what Plato might have called a cave.

a lively Platonic-style dialogue in everyday Italian, called Dialogue Concerning the Two Chief World Systems. It would finally prove to every reader why the Copernican heliocentric view was right and the old Aristotelian view wrong: all with—he hoped—the approval of the pope himself. In the spring of 1632, the work was finally finished. Galileo was approaching seventy.

More than any previous work, Galileo's Dialogue showed that if Copernicus wasn't right on every detail of the working of the solar system, Aristotle and Ptolemy were both very clearly wrong. The first printing sold out almost at once.

finishing his final work on mechanics and physics, Dialogues Concerning Two New Sciences in 1638, four years before his death. Down to the end, Galileo protested that he was a better Aristotelian than his opponents because he believed in avoiding fallacies in reasoning, and because he believed "it is not possible that sensible experience is contrary to truth.

This was perhaps the final irony. Galileo the obedient Roman Catholic became an overnight Protestant hero. He would be remembered as a champion not only of science, but of the principle of free inquiry versus papist tyranny, in Milton's words "a prisoner to the Inquisition for thinking in astronomy otherwise than the Franciscans and Dominicans licensed.

Galileo soon saw it was easier to explain phenomena like tides if you assumed the earth was not stationary, as Aristotle and Ptolemy had taught, but actually in motion.

The seventeenth century would be the great "century of genius" in science. It was the age of Galileo, Harvey, Boyle, and of course Newton. The political and social systems of Europe, however, seemed to have stalled out. Through his dark reading of Aristotle, Machiavelli had left behind a dilemma and a paradox.

At the time of Galileo the Church remained much more reasonable than Galileo himself. The process against Galileo was reasonable and just.

Mind-boggling, isn't it? Centuries before the question of why mathematics was so effective in explaining nature was even asked, Galileo thought he already knew the answer! To him, mathematics was simply the language of the universe. To understand the universe, he argued, one must speak this language. God is indeed a mathematician.

Moreover, Galileo argued that by pursuing science using the language of mechanical equilibrium and mathematics, humans could understand the divine mind.

Galileo was right, and the Church in this case abused its disciplinary power. As Pope John Paul II admitted in 1992: "This led them [the theologians who condemned Galileo] unduly to transpose into the realm of the doctrine of the faith, a question which in fact pertained to scientific investigation." Such acknowledgments, however, didn't come for almost four centuries.

It is a good principle in science not to believe any 'fact'---however well attested---until it fits into some accepted frame of reference. Occasionally, of course, an observation can shatter the frame and force the construction of a new one, but that is extremely rare. Galileos and Einsteins seldom appear more than once per century, which is just as well for the equanimity of mankind.

we had need to borrow that fantastic glass,invented by Galileo the Florentine To view another spacious world in the moon and look to find a constant woman there

The Franklin known to the French, the Franklin who had briefly visited Paris in 1767 and 1769 was—in Voltaire's description—the discoverer of electricity, a man of genius, a first name in science, a successor to Newton and Galileo.

I had no desire to share the fate of Galileo, with whom I feel a strong sense of identity, partly because of the coincidence of having been born exactly 300 years after his death!

In 1992 the Roman Catholic Church finally acknowledged that it had been wrong to condemn Galileo.
