A Quote by Nicolaus Copernicus

For it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study. — © Nicolaus Copernicus
For it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study.
For it is the duty of an astronomer to compose the history of the celestial motions or hypotheses about them. Since he cannot in any certain way attain to the true causes, he will adopt whatever suppositions enable the motions to be computed correctly from the principles of geometry for the future as well as for the past.
Just as one can compose colors, or forms, so one can compose motions.
Attempting to write vocal oriented songs to me felt like going through the motions and if you are going to go through the motions you might as well just do any gig that caused you to do repetitive motions like banging a hammer or serving fries.
What you compose with is neither here nor there, you compose with words, or you compose with stone plants and trees, or you compose with events; the Sheriff's officer, or whatever.
The existence of dark matter and dark energy are inferred from observations! They are not theoretical constructs. Though invisible, both reveal their presence through the effects that they exert on motions of celestial bodies and in the case of dark matter - the bending of light as well.
To compose our character is our duty, not to compose books, and to win, not battles and provinces, but order and tranquillity in our conduct.
I have to study, study, and study because I have to learn everything. Everyone expects me to be an expert on everything.
I am much occupied with the investigation of the physical causes [of motions in the Solar System]. My aim in this is to show that the celestial machine is to be likened not to a divine organism but rather to a clockwork ... insofar as nearly all the manifold movements are carried out by means of a single, quite simple magnetic force. This physical conception is to be presented through calculation and geometry.
The motions of the comets are exceedingly regular, and they observe the same laws as the motions of the planets, but they differ from the motions of vortices in every particular and are often contrary to them.
I may remind you that history is not a branch of literature. The facts of history, like the facts of geology or astronomy, can supply material for literary art; for manifest reasons they lend themselves to artistic representation far more readily than those of the natural sciences; but to clothe the story of human society in a literary dress is no more the part of a historian as a historian, than it is the part of an astronomer as an astronomer to present in an artistic shape the story of the stars.
To compose our character is our duty, not to compose books, and to win, not battles and provinces, but order and tranquility in our conduct. Our great and glorious masterpiece is to live appropriately. All other things, ruling, hoarding, building, are only little appendages and props, at most.
I lead no party; I follow no leader. I have given the best part of my life to careful study of Islam, its law and polity, its culture, its history and its literature.
It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses. Yet the thing is not altogether desperate; for we have some arguments to guide us, partly from the apparent motions, which are the differences of the true motions; partly from the forces, which are the causes and effects of the true motions.
I knew there was a school where women could study astronomy. So... it never occurred to me that I couldn't be an astronomer.
I have to throw in on a personal note that I didn't like history when I was in high school. I didn't study history when I was in college, none at all, and only started to do graduate study when my children were going to graduate school. What first intrigued me was this desire to understand my family and put it in the context of American history. That makes history so appealing and so central to what I am trying to do.
Study history, study history. In history lies all the secrets of statecraft.
