Atomic physics has proved to become a spectacularly successful software of quantum mechanics, which is among the cornerstones of recent physics.
3 @AaryamanSagar: std::atomic is a sort that allows for atomic operations. It won't magically make your daily life far better, you still really have to know what you want to accomplish with it. It can be for a very certain use scenario, and takes advantage of of atomic functions (on the object) are normally incredibly delicate and must be considered from the non-local viewpoint.
