Mathematics is a science Most people would disagree with that, though interestingly, that was not the case in the 19th century. http://en.wikipedia.org/wiki/Mathematics#Mathematics_as_science http://en.wikipedia.org/wiki/Mathematics#Mathematics_as_scie... It's all semantics, and not worth arguing much. But nevertheless, it's good to keep in mind that mathematics is about deduction. It starts from axioms and tries to find all of their consequences. Science is about inference, trying to figure out the axioms given the observable consequences. Maths is bottoms-up, science is top-down. [That's not the entire truth. Platonism in maths is a nice counterpoint to the above. http://en.wikipedia.org/wiki/Philosophy_of_mathematics#Platonism http://en.wikipedia.org/wiki/Philosophy_of_mathematics#Plato...] My vote goes to CS being a branch of maths.
