Mathematics itself is relatively easy, it is just a product of the human mind.
However science is not just the human mind, but empirical results refering to external reality. So one has to be able to adapt math. to something empirical.
It has been done in certain fields with varying success. Quite a lot in physics, but less in biology or psychlogy. Language is still more versatile and general as a tool.
First you need a good description. Then , if you can and its worth it , think of math.
Wise words. The history of human thought leads us to that conclusion. In some occasions the need takes us towards mathematics, for example the need to describe the movement and the differential calculus (Newton - Leibnitz), and in other occasions what is researched in Mathematics collaborates, for example, in statistics
