The Renaissance mathematician and astronomer
Nicolaus Copernicus was born 540 years ago.
He formulated a comprehensive heliocentric model
which placed the Sun, rather than the Earth,
at the center of the universe.
This heliocentric theory contributed importantly
to the rise of the ensuing Scientific Revolution.
In 1514 Copernicus wrote a forty-page manuscript
describing his ideas about the heliocentric hypothesis
seven basic assumptions for some friends and arround
1532 Copernicus had basically completed his work on the
manuscript of "De revolutionibus orbium coelestium".
But he rejected a fast publication of his theses,
perhaps from fear of criticism for around 7 years,
while he worked out more facts for his tehories.
Copernicus died in Frombork on 24 May 1543. Legend has
it that the first printed copy of "De revolutionibus"
was placed in his hands on the very day that he died,
allowing him to take farewell of his life's work.
