The son of a wealthy merchant, Copernicus was born at Toruń and educated at Krakow University and at various Italian universities where he studied medicine and law.

He was the first in Renaissance Europe to advance the heliocentric theory, namely, that Earth and other planets revolve around the Sun (hence the saying that 'Copernicus stopped the Sun and moved the Earth'). Copernicus was an astronomer, mathematician, he studied and practiced canon law, medicine, economy, diplomacy/ politics, and more. Nicolaus Copernicus (in Polish: Mikołaj Kopernik) was born on this day in 1473 (550 years ago) in Toruń, now in Poland. The date has not been chosen arbitrarily - the 19th of February is also the birthday of Nicolaus Copernicus 💫Ģ023 has also been declared as the Year of Nicolaus Copernicus in Poland, to commemorate his 550th birthday 🎉

Today we celebrate the Polish Science Day 🇵🇱, in recognition of the achievements of Polish scientists. 'To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.' 💡
