WEBQuantum mechanics can be baffling, yes, surprising, definitely, and certainly counter-intuitive. That’s because quantum mechanics lives outside of our everyday lives and any attempt to explain quantum phenomena using classical physics fails. Quantum mechanics just is, and it’s awesome!
WEBQuantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to. The descriptor \quantum" arises because in contrast with classical mechanics, certain quantities take on only discrete values.
