blurry depths
Mathematics clarifies but also trivialises whatever it touches. Its arrival often signifies that the problem at hand is solved.
That is why frontiers of all disciplines are non-mathematical.
Mathematics can not touch things that we only "half" understand, but it is always there when we fully understand.
Students are taught completely dead material in schools, not the frontier stuff. They are bombarded with solved problems in neat mathematical forms. Many smart and creative students get burned out in this process and leave academia for good.
I find this really troubling. Depths are non-mathematical and the problems there require collaborative efforts of all sorts of different minds.
Here is my career advice: Know your math but dive in blurry depths as soon as you can. (Warning: This may decrease your hireability!)
Stop analysing stock price movements, become an entrepreneur instead. Stop reading physics, engage in philosophy of physics instead. Stop doing conversion optimisations, become an user experience designer instead. You will feel more fulfilled. Trust me!
