  • Makes sense though.

    The complex Riemann-Zeta function (Zeta(x) = sum from 1 to infinity of 1/n^x) only converges for Re(x) > 1, else it is infinite. We can use analytic continuation - which I understand as extending the function such that it remains holomorphic (basically continuous but in the complex numbers and for some reason well-defined) and find the value of Zeta(-1) that way.

    The value of Zeta(-1) when viewed this way is -1/12.

    It’s not really saying the sum of all natural numbers is equal to -1/12. It’s really just a mathematical trick, just like: lim (x -> 0) x/x = 1 but this doesn’t mean 0/0 = 1.






  • I consider Wikipedia more reliable than vast portions of primary sources. I have seen the awful quality of many papers - “publish or perish” is a thing in science.

    And yes, obviously the label “narcissist” is an insult. Just like calling someone “stupid”. When using it as an insult however, it is clearly meant to say this person displays high amounts of narcissism and behaves like a self-centered asshole.

    This is different to insults such as “autistic” because that is not a personality style but rather a clinical diagnosis. It would be akin to using the term “disabled” as an insult.

    Narcissism is a negative trait if you have too much. That is why it’s an insult. If I say someone is “smelly” I am also insulting their body odor. Doesn’t mean people who struggle with body hygiene for whatever reason should also feel insulted by that.
