I found this website and i really enjoyed reading it. It has a very nice in depth biogrophy on Nicolaus Copernicus, Which I found out in this article that it is not actually his name he was born under a different name, Mikolaj Kopernik. It goes on in great detail of the life of Copernicus, his education, and his studies.

This is stanfords academic library. It has loads of information everything from his life to his studies and accomplishments. I find the information on this website to be very helpful and clear. It is very clear and from my knowledge is very accurate.

This Website has really nice diagrams and drawings of Copernicus Helio-centric model

  • Nicolas Copernicus pub. De Revolutionibus Orbium Calestium in 1543
  • He was motivated by the fact that ptolemaic model was not pleasing, it broke its own rules about the earth being in the center of the universe
  • His writings explained two critical observations more simply than Ptolmey. Retrograde loops were caused by an illusion: as inner planets pass an outer the outer one appears to move backwards.
  • inferior planets are closer to the sun than the earth, som they can never go behind us.
