        X^3 = x•x•x

        X^2 = x•x

        X^1 = x

        X^0 = 1

        X^-1 = 1/x

        X^-2 = 1/(x•x)

        X^-3 = 1/(x•x•x)

        When the exponent is between -1 and 1, it becomes a root function:

        X^(1/2) = sqrt(x)

        X^(1/3) = cubic root(x)

        X^-(1/2) = 1/(sqrt(x))

        X^-(1/3) = 1/(cubic root(x))

          Oh I misunderstood the original comment, the teacher said it wasn’t the same, but it is the same. My understanding is that sqrt(x) = x^1/2

    Shakespeare’s plays were never printed in his lifetime, they were compiled from people who saw the plays live, went home, and wrote down what they remembered.

    “You need to go to college to be successful or you’ll be flipping burgers!”

    So said teachers, parents, career counselors, etc. and here we are, I beat school, and no jobs. Should’ve become an electrician.

        They either had rich parents with rich connections, or had incredibly loyal, highly skilled friends, like Jobs had Wozniak.

          I wondered that too, but then you have people like Whoopi Goldberg and Chris Rock on that list. And it’s not like Will Smith was that rich friend.

            Your also looking at a very specific field. Some fields require a degree and others require talent and a nonstop work ethic to just get out there and do it day after day and push through those hardships.

          Employment doesnt necessarily mean “most successful” but education is obviously importer regardless if its self-directes or not.

          And i love me a distribution graph. Thank you.

    I had a teacher confidently tell the class that Mt. Everest didn’t border China (well Tibet really, but that’s a battle for another day). I will say she was able to concede she was mistaken. I had another teacher hit on me when I was in high school while I was alone with her in the copy room. I had always heard some salacious rumors about her, but I always assumed they were just idle gossip until that day. That was a different kind of wrong. And no, I didn’t take her up on the advance.

    I’m assuming English isn’t your first language, so just as an FYI, wrongest isn’t a word. “Most false” is probably the best fit in this instance. Just one of those weird quirks of this bastard language.

      You’re right, it’s my second language. My first/native language actually doesn’t have official spelling rules, so yeah, it’s a handful.

        Hey, OP, they’re wrong. Not the wrongest they could have been, but it is indeed a word. A quick check with any online dictionary will confirm that.

        It might be considered poor style to use it in educated language, where “most wrong”, “most incorrect” or “most false” might be better choices, which is probably the context they were thinking of, but it’s definitely a word and people do use it.

    I remember a bunch of things in science class in middle school, because I was really into science and it bothered me that they oversimplified everything to the point of being straight up false. Like a definition of “animals” being “something with eyes and a mouth”. I mentioned several examples of animals without eyes, like corals, but the teacher just exasperatedly said that they did have small mouths. Ok, but your definition said eyes and a mouth, not or.

    I also remember a question in a test about astronomy being “what is the biggest object”. I thought about it for a moment and then wrote “the universe”; which I’ll maintain to this day, was right. But it was marked wrong. The expected answer was the sun. I talked about it to the teacher, because it wasn’t like I pulled the existence of objects bigger than the sun from my personal knowledge only, we’d explicitly talked about bigger stars and galaxies. But the teacher said "It was implied ‘biggest object in the solar system’ ". Implied how? It definitely wasn’t written. I still want my point back.

          …wait, really? I know back then it was probably anyone’s guess, but that sounds like one of those oddly specific things that makes the moon being made of cheese sound like a down-to-earth conclusion.

            I checked, and it looks like I’m a bit off: Anaxagoras estimated that the moon was the size of the Peloponnesus and the sun was somewhat larger—but how much larger depended on how much further away it was, which he had no means of guessing.

            His estimate of the moon’s size was derived from observations of a solar eclipse, in which the path of totality was about the size of the Peloponnesus—but he probably missed a lot of places that experienced a partial eclipse and didn’t make note of it.

              I mean his train of thought deserves credit, just not for factoring in everything. A good Greek philosopher was like the Sherlock Holmes of their day; I recall reading Aristotle saw the Earth’s shadow on the moon and how it curved and he was like “ah, so the Earth isn’t flat, it’s a ball” (though then he’d go on to say stuff like “other cultures are less prone to revolution, so they must be natural slave cultures”, which would be more like Half-Life 3’s hypothetical version of Sherlock Holmes).

      The sun? The sun!? I guess your teacher didn’t know about Aldebaran, the size of galaxies… Supermassive black holes… Galactic filaments… And yes, the universe itself.

        Nah, she’d mentioned some of these things. The logic was just that since the other questions in that test had been about objects in the solar system, I should’ve known it was implied “biggest in the solar system” although it wasn’t written.

      Pores in latex lamb skin condoms bigger than the AIDS virus.

      That’s probably what they were going for, but you’d think a teacher in that position would check their data if challenged.

      We had that taight in our high school too!

      (And as a totally unrelated fact I’m sure, our biology teacher was a major figure in our local church and was pro abstinence. Completely unrelated, of course)
