The one I always find funny is tech CEOs or ads out there that use the term “quantum leap” to describe an improvement. In reality, a quantum leap is just when an electron changes orbitals – one of the smallest movements a piece of matter can make. In my mind, a device being described as a “quantum leap” ahead of it’s predecessor sounds like it’s barely changed at all. Even better is the state is often temporary as electrons jump up an orbital when absorbing energy and then will jump back down when they release it. All in all, a terrible marketing term.
