On This Day, 2-19-08: Copernicus

1473: Copernicus born

On 19th February 1473, Nicolaus Copernicus was born in Torun, Poland. The father of modern astronomy, he was the first to propose that the Earth and other planets revolve around the sun. Prior to the publication of his Concerning the Revolutions of the Heavenly Orbs in 1543, European astronomers argued that the Earth lay at the centre of the universe, the view held by most ancient philosophers and biblical writers.

Copernicus also argued that the Earth turned daily on its axis, and that gradual shifts of this axis accounted for the changing seasons. He died the year his major work was published, saving him from the outrage of some religious leaders who condemned his science as heresy.

I CAN easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected.
Nicolaus Copernicus

Accordingly, since nothing prevents the earth from moving, I suggest that we should now consider also whether several motions suit it, so that it can be regarded as one of the planets. For, it is not the center of all the revolutions.
Nicolaus Copernicus

Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.
Nicolaus Copernicus
