We are getting somewhere. So you believe that science without maths > is nonsense ? I am merely countering your nonsense that math without science is nonsense. According to history, and what can be deduced of prehistory, there was a good deal of math, at least arithmetic, around long before there was any science at all.

They are a part of the applications of mathematics to things other than mathematics, so they are marginal.

I am quite wiling to accept that there are sciences to which the need for mathematics is largely, if not completely, incidental. |
