Dear Dr. Jayakar
I read with great interest your essay and looked at your research website. Your work reveals an original and well developed way of thinking about the fundamentals of physics. You propose tetrahedral units of electromagnetic energy and the way they interact is by the rotation of these units. As such I agree with you because my own Beautiful Universe Theory also found here posits that everything is made up of dielectric lattice of nodes transmitting rotational energy, that is, angular momentum. These nodes are arranged in a Face-Centered Cubic arrangement like a crystal so that tetrahedral arrangements are embedded naturally within the system. fqxi contributors and others also proposed tetrahedral building blocks, but not in the way you have done.
You are more knowledgeable than me about particle physics, Feynman diagrams, etc. and I have no doubt that within the logic of your theory you are right. What I find a bit confusing is that you express your original ideas with the vocabulary of the 'other' physics - strings, probability, etc. This gives them some credibility but does not add to their understanding. I wish I able to comment on the many technical points your theory raises, but your ideas are certainly an original way to answer the It Bit question. I wish you the best of luck.
