Its fixed. But I wonder, why english speaking countries rename something. I mean his name was Kopernikus with K and not with C. So can you explain to me, why such names are renamed?
Why is a good question. To make the pronunciation easier may be the reason sometimes but with Kopernikus or Copernicus that can't be it. It's no only the English speaking countries though. I'm always confused when Germans come up with different English titles for films with an English title.
Well, apparently, his name was neither Kopernikus nor Copernicus. His real name was Niklas Koppernigk. Thus Copernicus derives from its Latinized version. But as Germany and English tend to have a different methodology for transliterating Latin, German replaces c by k - English doesn't, his name differs.
