Discussion of 394(7)

This is a very good idea, and I will sketch out the calculation by hand and send over to you to use Maxima

Subj: Re: 394(7): Shivering of the Contact Term

PS: perhaps the delta r terms can give a different result for shivering.

Computer algebra gives that the contact term vanishes because of

nabla^2 (1/r) = 0.

As can be seen from the protocol, all terms cancel out.

The contact term in NMR is shown to have a similar structure to that of the magnetic dipole field. This is not apparent from its usual representation as a Dirac delta function, Eq. (2). The effect of the vacuum on the contact field is given by Eq. (17). This seems to be a new insight to the contact field. The vacuum will affect the hyperfine spin spin structure of NMR. There are many ways of representing the Dirac delta function in mathematics, and each method can be corrected for the vacuum shivering. That will lead to a lot of interesting graphics. Dirac’s original idea of a delta function was dismissed outright by mathematicians as complete nonsense, despite its success in physics. The mathematicians later developed theories for the Dirac delta function that showed its deeply insightful nature. As Horst and I have shown in various UFT papers on the Dirac equation, he was not bothered very much about the finer points of mathematics if the physics emerged in a way that made sense. This is OK as far as it goes, but as we have shown, Dirac missed a lot of physics and a lot of people went on missing it for almost a hundred years because they just followed Dirac.
