Why was coperrocus so important
During the fifteenth and sixteenth centuries reen in europe began to look at ideas
that had been accepted since the time of the Greeks and to reexamine them. We call this gret and to reexamine then we call this great upsurge in thinking the renaissance. Nicolas coopernicus ws born in poland in 1473. He became a Romoan catholic cleric and was particularly interested in astronomy. After carefully observing the plants and calculating their movements the discovered newer and simpler ways of explaining their motions. He realised that the moon
travelled round the earth,but he came to believe that the earth and the rest of the planets,travelled round the sun. He still thought that all the heavenly bodies travelled round the sun in perfect to believe in a sphere of fixed stars. This idea of the cuniverse is called the heliocent ric or sun-central theory,with the sun at the centreof the universe. Because his ideas were so new,copernicus delayed publicatin of his book,De revolution bus orbium coelestium (on the revolutions of the hevenly spheres)until he was dying because he ws disturbed at what the reactins of the church
authorities might be. They held that the reactins of the church authorities might be. They held that the earth must stand still and it was to be a long time before they changed their minds. His book is os important because it formed the basis of all the new thinking about astronomy that was to takeplace in the next two hundred years.
