Is this some kind of joke?

1 + 2 + 3 + 4 + 5 + ... = -1/12
No, it's improper/misleading notation and poorly explained methodology. Note how the professors are both physicists, not mathematicians. I really don't know why Brady didn't just get an analyst to talk about/explain the [math]\zeta[/math] function.
No. It is the ultimate math redpill. -1/12 is of greater significance than pi or even e, since the quantum infrastructure that the infrastructure in which those exist would not be possible without 1+2+3+4...being equal to -1/12.

Yes. This is easily their shittiest video.
Obviously the sum of all natural numbers for the simple meaning of sum will be infinite. However, let's say you're in a case where you have some mathematical description of a problem where one term is a finite number, and you apply some generic manipulations to the whole problem, and suddenly that finite number turned into a divergent series. With the regularized zeta function (or other methods of proving the same result) you can just replace that divergent sum with a finite number and it just werks.
Purest bullshit

I didn't find an error in his proof.
