      I would say Maxwell’s Demon:

      Maxwell’s demon is a thought experiment that would hypothetically violate the second law of thermodynamics. It was proposed by the physicist James Clerk Maxwell in 1867. In his first letter, Maxwell referred to the entity as a “finite being” or a “being who can play a game of skill with the molecules”. Lord Kelvin would later call it a “demon”.

      In the thought experiment, a demon controls a small massless door between two chambers of gas. As individual gas molecules (or atoms) approach the door, the demon quickly opens and closes the door to allow only fast-moving molecules to pass through in one direction, and only slow-moving molecules to pass through in the other. Because the kinetic temperature of a gas depends on the velocities of its constituent molecules, the demon’s actions cause one chamber to warm up and the other to cool down. This would decrease the total entropy of the system, without applying any work, thereby violating the second law of thermodynamics.

        That’s interesting to think of the warning with knowing that. Thanks for explaining.

    The perpetual motion one makes sense I think since I’d something can run forever could you even stop it? Or maybe it holds a certain torque until acted upon by a greater force

    “The lumber mill had to be shut down because someone overloaded the perpetual motion machine providing power to it and now the bosses are trying to figure out if they can get it fixed or if it’s cheaper to buy a new one, they just don’t make things like they used to”

    Absolutely love the idea!

    Unfortunately I find execution lacking. There is too little visual consistency. Different signs don’t look like a pictographic system, but instead as icons from different styles and systems pasted onto a common template.

    I love these!

    I guess I will have to upload my scifi NATO-symbols at some point, here’s an example (it’s a bipedal non-atmospheric reconnaissance mech):
