/sci/ - Science & Math

I have a degree in mathematics and I still think mathematics is boring and useless. There is math which is useful in physics, engineering, statistics, operations research, computing, etc. but that math is now mostly done outside math departments; math departments instead focus on abstract nonsense.

World's élite universities (e.g. MIT, Princeton) will tell you right away that as their CS student you are considered the best group they have and that math students go slower than you, and increase your load to crazy levels As a CS student, you are expected to master (continuous) calculus, discrete calculus (discrete math proofs, hypercubes for parallel algorithms), optimization (machine/deep learning, compilers), category theory (functional programming), logic (up to automated proofs, i.e. including set theory), differential equations, topology (computational geometry, distributed algorithms), probability and statistics (reinforcement learning, queueing), number theory (cryptography), graph theory (almost everywhere)... There is no functional analysis needed yet, but it's heavily used for PhD degrees anyway. You need to know all this down to the level of proving theorems if you want to achieve anything in CS.
