Momentum in an Electric Circuit
I know what energy and power is in an electric circuit. It occurred to me I have not ever asked what momentum corresponds to.

Entangling 2 different color photons
What I think is interesting about this is that since they are 2 different frequencies it becomes much harder to blame the strange behavior of entanglement on phase coherency. Beware I could still be wrong about that.

PAM Dirac Lectures in New Zealand 1975
PAM is a legend
This guy was around for the Solvay conference in 1927. A good recounting of the history of quantum mechanics and the mathematics underlying.
Note: In this episode he explains the correspondence of the particle and the wave outlook in terms of the harmonic oscillator.
