Fragment of a discussion from Talk:Applications/Science

Of course, science uses math to describe their theory. But math itself is an abstract theory and has nothing to do with describing or understanding real nature. So it doesn't fit into the science category, imho. E.g. I think I would not expect a CAS like Maxima in the science category. Adding "Math & " or " & Math" and then we could add Kig, too, couldn't we?
