Category: 3.The Essentials of Quantum Mechanics

When you describe the state of a physical system, you collect all the pa- rameters required to fully specify it: for instance, the state of a ball may be specified by its position in space, its velocity, and maybe its rate of spin; the state of a volume of gas by its temperature and its…

How do we describe the state of a quantum mechanical physical system in a mathematically precise way? How do we ascribe physical properties to this system? How does the system evolve in time? How do its properties change when it interacts with another system or a force? How do we measure and determine its properties?…
