"Mathematics is written for mathematicians." — Nicolaus Copernicus

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.

For it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study.

For I am not so enamoured of my own opinions that I disregard what others may think of them.

In so many and such important ways, then, do the planets bear witness to the earth's mobility.

The earth also is spherical, since it presses upon its center from every direction.

Mathematics is written for mathematicians.

So, influenced by these advisors and this hope, I have at length allowed my friends to publish the work, as they had long besought me to do.

The massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.
