    Going through old forum posts is a great way to mine old turns of phrase you've forgotten, inbetween the wildly contradictory positions you've held in various discussions.

    Quick poll: if I ask what (-8)^(1/3) is, how would you answer?
  • DYREDYRE
    -2 and then I know there are two others but I can't remember how to find them. I'd then be annoyed I don't know how to find them and then go to Wolfram Alpha to learn that they're 1 +- 1.7321i.

    Cool, thanks, I'm not insane.

    Background: I was working through a math problem with a friend and I offhandedly said something like "(-8)^(1/3) is better known as -2". Which he insisted was wrong, somehow. Wolfram Alpha did not help since if you type that in it gives you one of the complex ones as the primary answer, though it does give -2 if you type "cube root of -8" instead. The context was actually expressing all the roots of x³ + 8 by taking one and multiplying it by roots of unity, so it made no difference which was picked as the "primary" root anyway...

    FYI, typing "-8^(1/3)" into a TI-89 gives the answer "-2" under both "REAL" and "RECTANGULAR" complex formats.

    That said, the TI-89 also has solve and cSolve functions.  "solve(x^3=8,x)" produces "x=-2", regardless of complex format, and "cSolve(x^3=-8,x)" produces "x=1-sqrt(3)*i or x=1+sqrt(3)*i or x=-2", again regardless of complex format.

    I think the issue is that fractional exponents are interpreted as root functions, and root functions are generally interpreted as producing the real (and positive, if possible) roots.  Whereas simply asking "what are the roots" will more validly be answered with complex answers.

    ^^ Why not just point out that (-2)(-2)(-2) = -8?

    I did. It still took me like ten minutes after that to convince him that that's the same thing.

    I've seem to have gone back to regularly working on my long overdue thesis.

    I'm also back to studying languages, specifically Japanese, after a two years pause. I'm pondering whether to go back to my old flashcard deck and its long overdue reviews, or make a new deck.

    Huh, so I just found out Fast Eddie is no longer TVT's admin. I think that's a good thing for both him and the site.

    Also, I don't like that HH doesn't like us.

    I'm surprised anyone can dislike us considering how completely mild-mannered this place is.

    Is he still the owner?

    Who?

    Pretty sure that the HH leadership is just fine with us.  They're actually assistant mods here and I'm an assistant mod there.

    There are a few (I can think of two; I won't name) specific people who left here and only hang out there, but that's not really the same as the entire site.
  • StormtroperStormtroper

    i dunno lol

    This is the (old) announcement thread, doesn't mention it but sounds like it has a new owner.

    Who?

    Heaper's Hangout

    ＾*shrug* it's the impression I get often when the topic's brought up. Not that I go there often enough to tell for sure.

    @Noimporta you may be entertained by my comment here: http://heapershangout.com/index.php?p=/profile/3/Imipolex G

    To be fair, I also have roughly zero idea who those two guys are. Also, that only works if one's stealing someone else's face.

    I think Imipolex was the southern US guy with fascinations with boobs, some philosophical inclinations and that used a Plague doctor avatar on TVTropes. The other is not known to me.
  • Naas_HumanNaas_Human
    I remember Imipolex being described as really tall or something.

    Panurge on HH was using that avatar earlier, but not green.

    Wasn't Zephid the one with the Plague doctor avatar?

    It wasn't Imipolex G, at least. The avatar I associate with him is Raphael the Raven.

    You are right, it was Zephid. Damn, foiled by my own memory
