Moments Memes

Physics students staring at this chart during an exam is the true definition of "moment of inertia." Your brain suddenly forgets which formula applies to which object, and you're left wondering if you're a solid sphere or just a hollow shell of your former self. The professor is like "Pick the right formula!" while your brain has decided to have zero rotational acceleration around the axis of knowledge. Trust me, I've been there—frantically trying to remember if I'm calculating for a rod about its end or just the end of my academic career.
