Nations are not ruined by one act of violence, but gradually and in an almost imperceptible manner by the depreciation of their circulating currency, through its excessive quantity.
Nicolaus CopernicusRead
Finally we shall place the Sun himself at the center of the Universe.
Interpretation
Copernicus emphasizes the heliocentric model of the solar system, where the Sun is at the center.
This quote by Nicolaus Copernicus reflects a revolutionary shift in understanding our place in the universe. By advocating for the Sun as the center of the cosmos, he challenged the long-standing geocentric model that placed the Earth at the center, paving the way for modern astronomy and a deeper comprehension of celestial mechanics and our role in the universe.
In practice
During a science presentation about the solar system, this quote can illustrate the historical significance of Copernicus' work.
Nations are not ruined by one act of violence, but gradually and in an almost imperceptible manner by the depreciation of their circulating currency, through its excessive quantity.
So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.
So if the worth of the arts were measured by the matter with which they deal, this art-which some call astronomy, others astrology, and many of the ancients the consummation of mathematics-would be by far the most outstanding. This art which is as it were the head of all the liberal arts and the one most worthy of a free man leans upon nearly all the other branches of mathe matics. Arithmetic, geometry, optics, geodesy, mechanics, and whatever others, all offer themselves in its service.
Those who know that the consensus of many centuries has sanctioned the conception that the earth remains at rest in the middle of the heavens as its center, would, I reflected, regard it as an insane pronouncement if I made the opposite assertion that the earth moves.
The strongest affection and utmost zeal should, I think, promote the studies concerned with the most beautiful objects, most deserving to be known.
The massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.
Not to leave planet Earth would be like castaways on a desert island not trying to escape...Sending humans to other planets ... will shape the future of the human race in ways we don't yet understand, and may determine whether we have any future at all.
In a spiral galaxy, the ratio of dark-to-light matter is about a factor of ten. That's probably a good number for the ratio of our ignorance-to-knowledge. We're out of kindergarten, but only in about third grade.
We need to get across the excitement and creativity of science. That it isn't just a list of facts that have already been discovered - but a process, a creative project, that you are generating ideas, testing them and looking for evidence.
From the beginning of the Radiation Laboratory, I have had the rare good fortune of being in the center of a group of men of high ability, enthusiastic and completely devoted to scientific pursuits.
Scientific and technological progress themselves are value-neutral. They are just very good at doing what they do. If you want to do selfish, greedy, intolerant and violent things, scientific technology will provide you with by far the most efficient way of doing so. But if you want to do good, to solve the world's problems, to progress in the best value-laden sense, once again, there is no better means to those ends than the scientific way.
I was the most emotional of the flight directors. Space really got me all honked up.
