Q: Is it of any coincidence that mathematics is able to describe physical reality – given that both are inventions of the human mind?
Physicist: There’s a lot of math that doesn’t describe physical reality at all, and even some (few) mathematicians who feel that“applicability” is just another word for “impurity”. The ability of math to describe reality is just a consequence of the fact that reality is nice and consistent. The fact that the math we use (addition, subtraction, geometry, calculus, whathaveyou) works is no coincidence at all. It doesn’t describe reality (in this case the reality that the ratio of the circumference to the diameter of a circle is ), so it goes the way of the Woolly Mammoth. I assume that this question is about perceived reality (colors only exist in the brain, whereas in reality there is no “blueness” or “redness”), and not physical reality.
