Comment on I must con(FeS₂), this sparked a laugh

  I work in public education. That’s a pretty innocuous statement compared to some of the shit I’ve heard. Some teachers get so complacent in their lessons that they forget to apply it in their critical-thinking. Then, they have some crazy logical lapse, say something ridiculous out loud, and then some other kid from that class repeats that same shit to their own students when they grow up. These are mistakes that could easily be rectified with an apology or deliberate correction, but teachers are pushed so hard to prioritize being an authority figure that they sometimes forget to just be a teacher.

    I’m going to pull a no true Scotsman, no good teacher would say that.

    yhea, there are teachers that lose it a bit.

  no science teacher would ever say that.

  Careful with those absolute statements there buddy. I was told the same by a teacher, who challenged the class to come up with natural examples of either straight lines or perfect circles. He talked about how such things cannot exist because at high enough resolution/magnification there will always be interruptions.

  Your own example of light traveling in straight lines doesn’t account for the fact that photons are waves and absolutely do not travel in straight lines.

    It travels in a straight line, just not in every dimension. Look at a waveform from above, it’s a straight line.

    they do tavel in a perfectly straight line though.

    space time is curved, not the light path.

      False because they are affected by gravity, even if ever so slightly

      • Maldreamer@lemmy.world ⁨1⁩ ⁨day⁩ ago

        But isn’t the gravity bending the space, so the light itself is travelling straight but seems curved to the observer?

        gravity isn’t a force, it’s the curvature of space-time itself.

        light follows a perfectly straight line through vacuum. the space itself isn’t straight.

        like drawing a straight line on a flat paper, if you roll the paper, that line is still straight within it’s medium.

    But photons are also particles.

  We can say that spatially, the summation of the photons movement is linear, but everything in the universe is waves and curves and we all know that to be true

    if by straight you mean a perfect eucledian line, then there’s no such thing as a perfect line in nature or reality.

    as that might violate the Eisenberg Uncertainty principle. because if I know two points position or or if I know the direction and one point I’ll know the position and direction of every point.

    but then that’s too esoteric.

      You are clearly full of shit and have no idea what you’re talking about, and your flip-flopping between positions

        it’s a meme channel, it’s a stupid question, you get stupid answers.

        I’m not putting my name in a paper saying definitely of straight exist in nature.
