Convince me why i should take math seriously

you have no idea what you are talking about

Ok I see how you got it but that's just mathturbation right? 1+2+3+4+... Doesn't actually equal -1/12 in the real world so there has to be a flaw in the formulation or a law of math. Or is this just something wrist deal with cautiously.

gee I wonder why people didn't think of assigning to zeta(1) a value of y-intercept of
1/1+ 1/2 +1/3 + ....

This meme needs to die. A mathematician applies analytic extension to fill in gaps for a specific function. A contradictory result pops out.

"Wow, I am not going to question the validity of my method and explore why it failed. I'll just assert that my method must be valid and so now 1+2+...=-1/12."

No real mathematician accepts this reasoning or result. It's meme trolls that perpetuate it.

Before Ramanujan, it was well understood that switching the order of terms in an infinite series changes the nature and properties of that series including potentially the convergence and limit of convergence. Consider:

1+1-1+1+1-1+... = diverges to infinity; let's just do a little creative term rearranging. Since I have and infinite number of 1's and -1's, let's write as follows 1-1+1-1+... now it oscillates between 1 and 0. So this series is bounded. Since they have different properties they clearly can't be equivalent or our definition of equality is blown up.

This is precisely why the concepts of sequences, infinite series, sequence of partial sums and limit of sequence of partial sums were developed and formalized.

>Ramanujan summation

Ignores all past formalization. It can generate reasonable results, but this is more an accident based on specific examples.

Bottom line, if the result looks too good to be true, it probably is false and you should explore why the failure occurred. If math is not consistent and reliable, it loses it's usefulness in real life.

but the -1/12 result is used in string theory

>but the -1/12 result is used in string theory

That is an argument against it, not for it.

I hope this is b8/pasta

Wait I thought the whole -1/12 thing was a meme
