>>14810509
t := a+b+c
a(a+c)(a+b)+b(b+c)(a+b)+c(b+c)(a+c)
= t[(t-b)(t-c)+(t-a)(t-c)+(t-a)(t-b)] -
[(t-a)(t-b)(t-c) + (t-b)(t-a)(t-c) + (t-c)(t-a)(t-b)]

4t^2 = (3t-a-b-c)^2 = (t-a)^2+(t-b)^2+(t-c)^2 + 2[(t-b)(t-c)+(t-a)(t-c)+(t-a)(t-b)]
(t-a)^2+(t-b)^2+(t-c)^2 = (b+c)^2+(a+c)^2+(a+b)^2 = 2(a^2+b^2+c^2) + 2(bc+ac+ab)
t^2 = (a+b+c)^2 = a^2+b^2+c^2 + 2(bc+ac+ab)
(t-a)^2+(t-b)^2+(t-c)^2 = t^2 + (a^2+b^2+c^2)
4t^2 = t^2 + (a^2+b^2+c^2) + 2[(t-b)(t-c)+(t-a)(t-c)+(t-a)(t-b)]
2[(t-b)(t-c)+(t-a)(t-c)+(t-a)(t-b)] = 3t^2 - (a^2+b^2+c^2)

2[a(a+c)(a+b)+b(b+c)(a+b)+c(b+c)(a+c)]
= t[3t^2 - (a^2+b^2+c^2)] - 6(t-a)(t-b)(t-c)

(t-a)(t-b)(t-c) = t^3 - t^2(a+b+c) + t(bc+ac+ab) - abc = t(t^2-(a^2+b^2+c^2))/2 - abc

2[a(a+c)(a+b)+b(b+c)(a+b)+c(b+c)(a+c)] - 3(a+b)(a+c)(b+c)
= t[3t^2 - (a^2+b^2+c^2)] - 9t[t^2-(a^2+b^2+c^2)] + 18abc = -6t^3 +8 t(a^2+b^2+c^2) + 18 abc

so all that's left to show is
-3(a+b+c)^3+8(a+b+c)(a^2+b^2+c^2) + 18abc ≥ 0
which is a trivial exercise left to the reader

And heroin is even more fun. Doing something because it is fun is not a good reason. It means you're an NPC doing it as a long convoluted chain of operant and classical conditioning for a bit of reward. The fact you never questioned why you should waste your time on this and your only answer to this question when someone asks it is "dude fun", shows how pathetic /sci/ bugmen really are.

You realize the same exact thing could be said about literature? You only chose to like literature because you weren't smart enough to get maths.

Math is for brainlets. Case in point: Goethe was so bad at math he remained convinced til the end of his life that he had BTFO'd Newton's color theory with his own, even though his was basically laughed at and Newton's theory clearly won the day.

The best mathematicians are basically illiterate in any other subject. Just look at their pathetic and abortive attempts to draw real world conclusions from their calculations. Too be good at math you have to be satisfied to use the tiniest part of your brain and forsake the rest. In academia mathematics is the equivalent of factory line work. Plato thought that mathematics was good mental exercise for children but clearly not a serious enterprise for a full-functioning adult.

It has even been noted that the more influential "mathematicians" were not very interested in math or very good at it--and even these were basically brainlets in every other subject (take Einstein, take Maxwell). This is because math is glorified sudoku. Math proofs are in the same tier as newspaper crossword puzzles. No one who actually wants to contribute to the inheritance of humanity would waste their time with it.

Difference is that you're trying to impose this challenge upon others, who are such responding with 'why'? The question is not why would I bother pursuing mathematics or any other activity (as you've interpreted it), but why should I carry out this particular task of which you've put forward for them. The superficially rather simple question is really asking you, the OP, why you've assumed that these people - or anyone for that matter - should care to attempt to 'win' your acclamation.

Also why would you assume a passion for literature and mathematics is mutually exclusive?

>You only chose to like literature because you weren't smart enough to get maths.

So you mould your 'likes' around what you deem would most prove your intelligence, either to yourself or others I presume. Then what is this intelligence to which you aspire to? Do you think that some are born 'more intelligent' (and able to 'get' maths) and others not? I disagree, other than marginal differences in brain structure and cognitive performance, I suspect that most can rise to the highest levels of mathematical proficiency if they truly chose, all levels of complexity in mathematics are made up of simple assumptions and steps at heart which anyone can accomplish
