Or, equivalently, in terms of the wave's angular frequency ω, which specifies the number of oscillations per unit of time, and wavenumber k, which specifies the number of oscillations per unit of space, by

Or two charged particles, each with a well-defined angular momentum, may interact by Coulomb forces, in which case coupling of the two one-particle angular momenta to a total angular momentum is a useful step in the solution of the two-particle Schrödinger equation.

Or, more rhythmically, ' The swarthy witches are laughing '??

`` Or do you want to see if I can stand fever, too ''??

Or singlehandedly decided to reverse national policy and hit the Soviets without provocation??

Or is this subject a matter of self-determination, a matter of states rights or county rights??

Why should I join the straying mass who want to make everything angular?

This condition is reproduced in modern quantum mechanics, but in the era of the old quantum theory it led to a paradox: how can the orientation of the angular momentum relative to the arbitrarily chosen z-axis be quantized?

Born in the Australian Outback, she is angular and tall, with elongated spikes emerging from her head which not even other Muses can quite idenitify: " was it hair?
