Question 1. Meaning of symbols
I'd have liked a little bit more explanation on what the equation means, especially what the symbols describe. You tell us about the wave function symbol, but not what the other two on the left and the remaining one on the right mean. Carl.
It’s a great question because although the wavefunction is the strangest and most important part of the equation from the perspective of trying to understand the differences between quantum physics and classical physics, each piece of the equation is enigmatic in its own way and tells us something about characteristics of the microscopic world

Question 2. Dirac equation relationship
Is the Dirac equation allegedly the generalised version of the advertised Schrödinger equation? If so, why is the Schrödinger equation still used everywhere by nuclear physics instead of the Dirac equation? Neoh.
If you look at the Dirac equation as written for example on http://en.wikipedia.org/wiki/Dirac_equation it takes the same form as in the billboard. So the equation we have written captures both possibilities you mention if you specify the mathematical structure of Psi and H in the right way

Question 3. The bouncing neutron
I don't understand what's meant by a neutron bouncing on a table, could you explain this in more detail? Irene.
Neutrons that are moving slowly enough are reflected from most surfaces. This reflection is due to the strong nuclear force and the wave-like nature of the neutron, and is similar to the total internal reflection of light at the interface between glass and air.
