... somewhat simpler than the LSZ discussion. But it relies on the identification of the initial and final states with their leading order expansions. We can refine this by thinking about the structure of the perturbation expansion. The LSZ formula systematizes this. LSZ has other virtues. Most importan ...

... • In quantum mechanics, measurements can only be expressed in terms of average behaviors since precision measurement of each event is impossible (what principle is this?) • The expectation value is the expected result of the average of many measurements of a given quantity. The expectation value of ...

At this scale, we find that interactions between objects a ...

As will be shown this leads naturally to quantization of electron momentum and kinetic energy, and consequently a manifold of allowed energy states for the electron relative to the nucleus. The de Broglie-Bohr model of the hydrogen ...

P2a Forces and Their Effects
... Car safety: The force on a passenger will be large if there is a large change in momentum in a short time. The key to safety is to extend the time of impact to reduce the force. This is done by: seat belts stretch a little, crumple zones at the front and rear, air bags to cushion the impact. ...
