My 15 year old brother's mathematical journey so far. Looking for opinions as I am concerned for his future. I believe that he can be an good mathematician in future
I'm his older brother, currently in college majoring in chem engineering. My younger brother is 15 and spends most of his free time doing mathematics. He also keeps a diary where he writes down his mathematical ideas, observations, achievements, and anything interesting he comes across.
This is some of the things he has independently worked on:
Rediscovered the basic trigonometric ratios before learning them in school.
Explored prime-generating polynomials. Explored ideas related to the nth prime.( He was 13 yr old innocent guy then )
Arrived at symmetric variation of the Goldbach conjecture.
-Investigated prime around expressions of the form 2^n + 6 ( if n is even then primes are -3 and + 1 from it and if odd then -1 , +3 from it , works for n as 1,2,3,4,5,6,16,18 etc.
Developed an infinite-triangle method for approximating polygon and segment areas.
Created generators for Pythagorean triples.
Arrived at the positive-index binomial theorem formula by observing patterns in expansions and translating those observations into a general formula.
Etc etc much more a lot of work and ideas he has he is kinda obsessed
I'm not claiming that any of these are new discoveries or that he has solved any famous open problems. I know it's possible that many of these ideas already exist and that he may have rediscovered known mathematics independently.
I'm just curious how unusual this kind of mathematical journey is for someone his age, and what you think would be the best direction for him going forward.
