>>14343165I am a mathematician, my science has a limited application. I can use the simplest things like the Euclidean algorithm in programming, the Pythagorean theorem to do some engineering things. but in general, simple things from mathematics are the most applicable, Dedekind rings and the base of topology are applicable to mathematical things and some things from advanced natural science, algebraic geometry cannot be applied in ordinary life, etc.
if you give a serious answer, then it seems to me that it is important to have a little superficial, but reliable knowledge about each science. it will be useful to understand what vessels, arteries, what white blood cells are. in physics it is useful to understand simple things.
sorry, I think I'm too simple and general things
in general, the idea is that simple things from physics, chemistry, biology, mathematics are of great use and will be extremely useful. if we talk about applied knowledge, then engineering will be very useful, not only simple engineering things, but also advanced engineering things can be useful
advanced things in physics or chemistry will have little use in life.
Mathematics will be the most fundamental, so formal sciences should be studied. if you have a need to learn the most fundamental and general things
if you just need to be efficient and have useful knowledge. then you should understand some superficial things from many sciences + some simple things from mathematics, and specialize yourself in applied and very profitable science: engineering, petroleum engineering, electrical engineering, nuclear engineering, etc.
