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.

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.
Interpretation
This quote highlights the societal reluctance to accept revolutionary ideas that contradict long-held beliefs.
Nicolaus Copernicus reflects on the historical consensus regarding the position of the Earth in the universe, noting how deeply embedded beliefs can cause resistance to new ideas. He suggests that challenging the prevailing notion that the Earth is the center of the cosmos would be viewed as madness, illustrating the struggle between established doctrine and scientific discovery.
In practice
In a lecture on revolutionary scientific theories, one might use this quote to illustrate the challenge of introducing new ideas.
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.
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.

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?
The uncertainty relation does not refer to the past; if the velocity of the electron is at first known and the position then exactly measured, the position for times previous to the measurement may be calculated.
Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.
There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.
If the tribal peoples actually represented Western origins at a much earlier time, it was exceedingly valuable that they should be studied intensely for clues about the nature and origin of human society. Consequently it was an injury to science and human knowledge to allow the military to simply exterminate them.
The Soyuz craft weighs tons, and you're lying on the floor of it on your back. But the Russians do tell you, remember, before you land, stop talking so you don't bite your tongue off.
