Quantum mechanics of a free particle from properties of the Dirac
... Our derivation of the Ehrenfest theorems is not generalizable to a non-free particle case because the standard derivation of the Ehrenfest relations requires knowledge of the Schrödinger equation. In summary, we have demonstrated that the eigenfunction of a free particle can be obtained from the as ...

... 8. Copy the figure below to your paper. This figure shows electric field lines. The electric field is constant and is equal to 1,000 N/C in the +Y direction. Draw four or five equipotential lines and label them with locations and values. (Hint: The V = 0 line is your choice, as are the scale and dis ...

Gravity, ruler of the Universe
... Albert Einstein completed his General Theory of Relativity. General Relativity is a “metric theory’’: gravity is a manifestation of the geometry, curvature, of space-time. Revolutionized our thinking about the nature of space & time: - no longer Newton’s static and rigid background, - a dynamic ...

Thus the total energy and relative phase of two interfering light beams may be measured with the precision allowed by classical wave physics, and any experiment which measures these variables, such as an interference or correlation experiment, will give the results predicted by classical theory.

Nature`s Book Keeping System
... In short, the difficulty seems to be that Einstein’s gravity equations include fields that describe the curvature of space and time. This adds a twist to our story: nature has to write its book keeping records on crumbled material: curved space-time. How do we make sense of that? A daring answer co ...

CHAPTER 11: Through the Looking Glass
... Maxwellian electromagnetics dealt with waves. But particles and waves are mutually exclusive. Whereas particles are localized in space, waves are distributed throughout space. Two particles cannot occupy the same space at the same time; two waves can. Waves may coincide constructively or destructive ...
