This (arguably unhelpful) phrase seems to be taught across schools all over the world. What are some other phrases like this that are common ?

    Didn’t that originate in a Sabrina The Teenage Witch episode? Or did I just imagine that?

    I don’t remember hearing that specific phrase in school. I remember hearing a teacher tell us to take deep breaths to fire up the mitochondria but not that it was “the powerhouse of the cell.” This was a meme that became common after my education was done. Because it became a popular meme it’s possible more teachers said it specifically along with whatever other fun phrases they had.

      I think a big part of why it took off and lives on as a meme in the internet forums sense of the word, was the familiarity of the bizarre and unnatural phrase to the young adults using those forums who remembered it from biology class.

      Certainly that’s how it was for me because before Digg, or Reddit, even before Facebook (though I guess not that long before), I had had that phrase uttered sincerely as part of my education and it was so uncanny and funny to see that this highly specific and distinctive phrase was used rote, word for word, at schools all over the world and was as memorably unhelpful to others as it had been to me. Perhaps the positive feedback loop from this phrase’s new life on the web really has fed in to education in a life imitating art kind of way like you describe, but I can assure you it definitely predated it’s status as a joke, and that’s where that joke came from.

        I’m not doubting it was used before the meme, I’m just doubting the ubiquity of it prior to the meme. I believe it is a bit of a Mandela effect type of thing. People remember the general purpose of mitochondria and remember their science teachers saying things similar to the effect of “powerhouse of the cell” even if they didn’t actually say that. Sort of like how “beam me up, Scotty” was specifically never used in Star Trek but just about every other variant of the phrase was.

          I’m not gonna go looking for scans or anything, but KnowYourMeme lists the popularity of this one as starting between 2013 and 2015, and I definitely remember seeing this phrase in a textbook around 2010 or 2011. So honestly, I might blame Pearson or McGraw Hill.

    While not unhelpful, stop-drop-and-roll and quicksand don’t come up as often as we thought back then

      I was always worried about proper handling of nitroglycerin. Talking to my friends it seems that wasn’t as common as quicksand or even thinking you’d need to tell gold apart from fool’s gold (pyrite). Games like Crash Bandicoot, shows like Dexter’s Lab, and a general interest in science may have meant I heard more about it as a kid.

    To the tune of “Pop Goes The Weasel”:

    x equals negative b /
    plus or minus the square root /
    of b squared minus 4 ac /
    all over 2a!

    I cannot believe that stupid fucking song is still in my head, but good God damn it worked. It’s there for all 0 times I’ll need the quadratic equation in my daily life.

      It was to to the tune of Frère Jacques when I learned it. https://en.wikipedia.org/wiki/Frère_Jacques

      Negative b, negative b
      Plus or minus square root, plus or minus square root
      B squared minus 4 AC, b squared minus 4 AC
      Over 2A, over 2A

      Finding the name of the original song was a pain. I’d never seen it written as an adult and thought it said “do re mi” so every search result kept telling me it was from the sound of music.

      If you already know that much algebra you can use ax2 + bx + c = 0 and solve for x to get the formula if you forget it.

        Hurr durr what if I just multiply the whole thing by 4a for some reason? Oh and then after that I’ll add b² to both sides, just for shits and giggles. And for good measure, I’ll move a few numbers from one side to the other, and that leaves me with 4a²x² + 4abx + b² = b² - 4ac.

        And then golly gee! Wouldn’t you know it? That just happens to let the left side factor neatly into (2ax + b)²! So I’ll just take the square root of both sides…

        No!

        No!

        Bad!

        This is fucking voodoo. I hate this shit. It’s like trigonometric substitution.

        Math is procedural. Math is algorithmic. Math is repeatable.

        “If these numbers looked a little different than they do, I could solve this. Oh, wow! If I just sprinkle these magic values into my problem, everything works out great!”

        Oh yes, I can see how if you just plug in this shit you pulled out of your ass, everything works out great! But when you aren’t around for a fecal transfer, I have no idea how to come up with that.

        I was top of my class in math. But that voodoo shit never made any sense to me.

        And there is absolute value of zero chance I could figure all that out in the heat of the moment if I forgot the quadratic formula. I had to work backwards from the formula to even get all that in the first place.

          • ax^2 + bx + c = 0
          • ax^2 + bx = -c move the c over
          • x^2 + (b/a)x = -c/a divide by a
          • x^2 + (b/a)x +(b/2a)^2 = -c/a + (b/2a)^2 complete the square
          • (x + b/2a)^2 = -c/a + (b/2a)^2 factor the left hand side
          • x + b/2a = sqrt(-c/a + (b/2a)^2) now we just tidy it up
          • x = -b/2a + sqrt(-c/a + b2/4a2)
          • x = -b/2a + (2a/2a) sqrt(-c/a + b2/4a2)
          • x = (-b + (2a)sqrt(-c/a + b2/4a2))/2a
          • x = (-b + sqrt(-4ac + b^2))/2a move 2a into the square root and multiply it with what’s inside

          The derivation of the quadratic formula is nice because it doesn’t rely on anything fancy and it’s all tricks the teacher is likely to teach around the same time you’re learning it. It’s not voodoo shit, it’s just the ax^2 + bx + c = 0 and you solve for x.

    I haven’t heard about mitochondria in so many years (obviously. why would I?) and I can’t explain why it feels so good reading this now.
