Today in 1473 Nicolaus Copernicus was born in the Kingdom of Poland. A mathematician, astronomer, and priest - he profoundly changed the way we think of reality, by formulating a model of the universe that placed the Sun rather than Earth at the centre of the universe. This was a major event in the history of science, triggering the Copernican Revolution. It challenged the authority of a literal interpretation of the Bible, but eventually was accepted. His heliocentrism was radical but his legacy is much wider that this. A polyglot and polymath, he obtained a doctorate in canon law and was a mathematician, astronomer, physician, classics scholar, translator, governor, diplomat, and economist. How has h is legacy been recognised in modern economics, and the periodic table?
