... If we make a substitution in favor of the fine structure constant, α = e2 /4πo hc, we could simplify things inside the brackets even further.i We can also note that l ± 12 is just the total angular momentum: l + 21 corresponds to the orbital angular momentum l being parallel to the electron’s spin ...

Etherism over Atomism: Space is a Substance.
... Copernicus, a monk, physician, and philosopher, did not believe that the God’s creation could be so unnatural and complicated. He revived Aristarchus’ idea that the Sun, not the Earth, was stationary and that Earth was just another one of the planets circling the Sun. His opponents raised arguments, ...

... As we have learned, mass is a form of potential energy. It can be converted into energy, or energy can be converted into mass. Because of this, mass does not have to be conserved in reactions. If you throw two balls at each other and they stick together (an inelastic collision), the resulting mass i ...

Ch. 27: Quantum Physics
... Recall from last lecture: The two postulates of special relativity: 1. The laws of physics are the same in all inertial (non-accelerating) reference systems. 2. The speed of light (in vacuum) is always measured to be c = 3.0×108 m/s irrespective of the motion of the observer or the source. ...

... The normal force exerted by a surface on a body acts at all the atoms and molecules of the common interface. Friction similarly acts at all points on the interface. To discuss the distribution of a force over a surface, one introduces the concept of force per unit area, which is called the stress. S ...

... Einstein argued that quantum mechanics is incomplete. Note that [x, ˆp] ≠ 0, but [x2–x1, pˆ 2+pˆ 1] = [x2, pˆ 2] – [x1, pˆ1] = 0. That means we can measure the distance between two particles and their total momentum, to arbitrary precision. So we can measure either x2 or p2 without affecting Particl ...
