Astronomy Benalla  Meeting Presentations - 16th September 2010   Astronomer of the Month  -  Presenter: Ian Corry Ian provided a comprehensive direct YouTube  presentation on astronomer Nicolaus  Copernicus ( 1473- 1543). Copernicus lived in Poland and died age 70. He was also a  mathematician, astronomer, physician, classical scholar, translator, artist, Catholic cleric, jurist, governor, military leader, diplomat, economist and multilinguist. Incredibly, as telescopes hadn’t yet been invented, Copernicus did all his observations and interpretations with the naked eye. Copernicus was known for his progressive theories on helio-centricity. In an era when the  Roman Catholic Church firmly believed in an earth-centred solar system; his hypotheses set the Earth in motion and the immovable Sun at the centre of the Universe. He  wrote a number of books including  his  last, great work – De revolutionibus orbium coelestium (On the Revolution of the Heavenly Spheres) – in Latin, not  just because of concern about religious objections as some of his earlier works had been given church approval, but because  it  was the  language  that  academia  used  at  the time  and  all  his  letters  to  the  government, the  church  and  even  educated  patient's  were  in  Latin. It is said that he also avoided  expressing  his  theories  too  strongly because of concern about possible astronomical and philosophical objections. De revolutionibus
