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
The earth also is spherical, since it presses upon its center from every direction.
Interpretation
What this quote means
This quote emphasizes the spherical shape of the Earth due to gravitational forces acting towards its center.
Nicolaus Copernicus highlights the Earth's shape as spherical, a conclusion drawn from the observation that gravity pulls matter towards the center from all points on its surface. This insight was fundamental in advancing our understanding of the Earth's physical properties and its position in the cosmos, challenging earlier models that depicted the Earth as flat or different in shape.

All quotes βSo 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.
Nicolaus CopernicusRead
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.
Nicolaus CopernicusRead
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.

The scientific value of truth is not, however, ultimate or absolute. It rests partly on practical, partly on aesthetic interests. As our ideas are gradually brought into conformity with the facts by the painful process of selection,-for intuition runs equally into truth and into error, and can settle nothing if not controlled by experience,-we gain vastly in our command over our environment. This is the fundamental value of natural science

The work of science is to substitute facts for appearances, and demonstrations for impressions.

If you're going to go into space, you have to have an objective, a mission. Where do you want to go? Earth orbit? The moon? Mars? What's the technology to get there? You develop the technology for the mission.

But I hope that it will also be demonstrated soon that in my experiments in the West I was not merely beholding a vision, but had caught sight of a great and profound truth.

The only useful function of a statistician is to make predictions, and thus to provide a basis for action.

If there is any kind of animal which is female and has no male separate from it, it is possible that this may generate a young one from itself. No instance of this worthy of any credit has been observed up to the present at any rate, but one case in the class of fishes makes us hesitate. No male of the so-called erythrinus has ever yet been seen, but females, and specimens full of roe, have been seen. Of this, however, we have as yet no proof worthy of credit.
