Atom - fine structure

electon's spin follows the direction of the external (i.e. orbital) magnetic field


spin2
mag1

unless it gets opposite ...

Atomic structure - Lamb's correction

Electrons in hydrogen atom are attracted by the nucleus but less than they should be .
It seems that  "empty" vacuum
is filled with something.
The plastic stick when electrically charged,
attracts pieces of paper; it also attracks blade, unless the blade is not in vacuum.

Particular relativity - time dilatation
1. at rest the path is 2L, and time t=2L/v, where  v is the velocity of the ball  shot1

2. in movement, the path is longer, but also the velocity is higher (unless in relativity conditions)  shot2

See the same from other direction: at rest, in movement



General relativity - Mercury's orbit

Only 1/r2 field assures closed orbits of planet.
Presence of Sun deforms space geometry - the field is not
1/r2 like: Mercurys' orbit is open
Try the following gravitational and non-gravitational funnels

Bose - Einstein condensation

In Bose-Einstein condensation, atoms (rotating tops) are trapped in a shallow magnetic well.

How does the laser work?


Laser requires at least one excited energy level which is enough long-lived (metastable).
Like these tippe-tops.

Greenhouse effect


CO2 molecule absorb heat because it is polyatomic molecule.
Ir means that it can vibrate in different modes and absorb different energy quanta.
Look how this bug effectively absorbs (and sends it back to the main spring).

This thanks to its six legs
