    [–] Help my friend and I settle a bet.. HarryPotter5777 2 points ago in math

    If you believe the odds are significantly better than 1:16 for Panama, you need to explain why no one else has capitalized on this opportunity for positive expected monetary gain. Most English fans might be patriotic and dumb - indeed, 99% of them might be. But if there is a single (rich) person in the world with some background in economics and enough money to safely take high-variance positive-EV gambles, they’ll be buying Panama bets until doing so shifts the odds down to whatever probability they do assign Panama of winning at. This seems like a situation (short-term liquid markets with publicly available information and betting) in which one would expect the efficient market hypothesis to hold; to state that you have a strategy which can predictably make money in such a situation is to refute the EMH, and it doesn’t seem to me that there’s a great reason to believe that it fails here.

    [–] A quick guide to find square root of y. HarryPotter5777 7 points ago in math

    Why make this an image when it would be infinitely more convenient as text?

    [–] Comic 3766: Build A Time Machine HarryPotter5777 4 points ago in questionablecontent

    Yeah, I know we've had a few background characters, but the implied Dina influence on a named character is new I think.

    [–] Comic 3766: Build A Time Machine HarryPotter5777 70 points ago in questionablecontent

    Is this the first time we've had such a direct cameo of a character from another comic in a canon strip? I feel like there's got to be other instances, but my usually-oracular memory of QC is failing to turn anything up.

    (For those not aware: the head in the bottom panel is Dina from the webcomic Dumbing of Age.)

    [–] Mathematics symbol dictionary? HarryPotter5777 20 points ago in math

    Lots of symbols are context-dependent; there's not going to be a perfect solution to this question. A decent first approximation would be to use Detexify to find out what some symbol is called (at least in LaTeX) and then googling that.

    [–] Can someone with an IQ of 110-115 excel at Math? HarryPotter5777 19 points ago in math

    Intelligence correlates with many measures of success across a population; for individual cases, it's not that useful of a predictor. Your conscientiousness, organizational skills, academic resources, and personal interest in the subject are significantly more important in determining whether you could pursue that degree than your IQ, and most of the relevant ways it does affect your prospects are better measured through more direct means.

    [–] Comic 3754: Maybe A Bounce House HarryPotter5777 6 points ago in questionablecontent

    Is the way I phrased it not the usual way of stating bets? I made an agreement that I'd pay my friend $10 if they didn't become a couple, and he'd pay me $1 if they did. (I guess really that's 10:1, oops.)

    [–] Comic 3754: Maybe A Bounce House HarryPotter5777 15 points ago in questionablecontent

    Wooo, won $1 off of a friend betting at 9:1 odds this would happen.

    [–] Relationships in QC HarryPotter5777 1 points ago in questionablecontent

    Straight guy here, no problem with dating a trans girl. In my experience, this tends to be pretty common among heterosexual people within trans-positive spaces; Marten’s not very unusual in this regard.

    Faye’s case doesn’t line up with her past sexual and romantic history, but nor is it uncommon in the real world; people not realizing their bisexuality until later in life or upon meeting the right guy/gal (especially if raised in Georgia like Faye) isn’t unheard of by a long shot.

    [–] How many ways can an n × m grid be tiled by 1 × k tiles in c colors such that no two tiles of the same color touch? HarryPotter5777 2 points ago in mathriddles

    The question isn’t about how many colors you need for a fixed tiling, it’s about how many ways you can assign tilings and colors under the given restrictions.
