If mathematics is a language, then how does it seem to describe all the observed things in the universe from helical DNA structures to black holes. Mathematicians and scientists have talked about the unreasonable effectiveness of mathematics. So is mathematics inherent in the universe or is it part of the way the human brain is wired? This question is being studied and some recent research can be accessed here.
