    Why is the mercury arc rectifier getting a “what the fuck”? I don’t know much about them, are they more magic than glowing rocks, runes, levitation and demon cores?

      Just piggy backing this comment to save people a click. A mercury-arc valve is used to convert alternating current (AC) to direct current (DC). It probably got a WTF for how weird it looks and how it looks like a crystal ball when it’s working.

        Are you telling me that’s a full bridge rectifier made of glass, liquid metal and plasma?🧙‍♂️

    But you want to know what is magic about physics?

    Forces. Forces are definitely observable. But they are fictitious. A photon (force mediator of the electromagnetic force) is a packet of energy on the electromagnetic field that creates a curvature in the electromagnetic field such that two particles with opposing charges (intrinsic charge) has that field curved together, resulting in what an observer would see as a force.

    Gravity? The thing keeping everything on the ground? Not real. Just a result of the spacetime field being curved by the presence of energy in it. In order to escape the curve, you have to exchange energy, which is to be a force.

        The fact that you knew exactly what I was talking about enough to pull up the relevant XKCD is impressive good sir/ma’am/(actually I don’t know what the non binary term would be there. I know military it’s “Sir” regardless).

    Anyway it’s still not clearly solved, several hypotheses, the Mpemba effect, a almost daily phenomen in which hot water freeze faster than cold one. Excluded evaporation as cause, because the effect is also observed in a closed container.

      Faster moving molecules will randomly arrange themselves into a lattice quicker than slower moving ones?

        Maybe, but scientist are still divided about the phenomen.
