Nicolaus Copernicus

Earth does not move except by a certain power.

The sun is the center of the planetary system.

Astronomy is the queen of sciences.

In my studies of astronomy and philosophy, I hold this opinion of the universe.

The planets wander among the fixed stars.

To assert that the earth revolves around the sun is to contradict common sense.

The apparent motion of the sun is due to the rotation of the earth.

I shall now call the world, or the universe, just as its parts were called in old times.

The sphere of the fixed stars is the outermost.

Philosophy is written in this grand book, the universe.

The earth is not the center of the universe.

Celestial bodies move in circles.

I am aware that a philosopher's ideas are not believed until they are confirmed by those of astronomers.

The moon revolves around the earth.

Truth in science can be pursued with diligence.

The heliocentric system simplifies the heavens.

Stars are fixed points of light.

My work may seem absurd at first, but time will prove it true.

The universe is governed by mathematical laws.

Planetary orbits are nearly circular.
