- Gigachad 4y agoI have been frequently surprised at how many physics questions are just unsolved. We know exactly what happens, which seems to be enough to do practical work with without having to know why. One that fascinates me is that blocks of metal with extremely smooth sides will stick together if moved in specific motion.
