At Jagiellonian University, a room I really liked was Copernicus's room. I found the globe that he made very interesting. Copernicus used his astrology background to map out where he thought all the continents will be in the future. The idea that he could map out the countries using geometry and a compass seems so crazy to me. He had no clue what the future would look like, but by using science he was able to predict a somewhat accurate world.
