Square root mass is also in equation (2) of the excellent paper "River Model of Black Holes" Hamilton & Lisle Am.J.Phys.76:519-532,2008: https://arxiv.org/abs/gr-qc/0411060 The paper is about a model of black holes on flat space-time. It's what you conclude black hole must be if you follow the...

If you type "C. A. Brannen" into a search at Amazon books you'll find a series my family published on military history. My favorite is: "Gunning for the Red Baron, C. A. Brannen No. 7: https://www.amazon.com/dp/158544507X/?tag=pfamazon01-20 So I suppose I should contribute to this thread. Wars...

Mitchell, that paper Modified Newtonian Dynamics and Excited Hadrons was quite a read; a paper I will read again as I'm sure it has insights I've overlooked. Zenczykowski has quite a lot of fascinating papers. I like the concept of "linearization". The way I interpret this, Nature is naturally...

Michael; What I've been concentrating on is QFT in 0 dimensions, that is, on things that happen at a single point in space or equivalently, things that happen without any spatial dependence. Without spatial dependence you cannot define momentum and without time dependence you cannot define...

If we take Koide's observation that his equation is perfect only at low energy limit, it calls into question the usual scheme of trying to understand the Standard Model as the result of symmetry breaking from something that is simplest at the high temperature limit. Contrary to that symmetry...

Schwinger's "Measurement Algebra" is a formulation of QM that is more compatible with Rovelli's relational principle in that it talks about interactions instead of properties of quantum states. He's not avoiding an observer but is taking into account the interaction between the measuring...

<<Ie. it takes a third observer to describe the relation between two other observers. But Rovelli never analyses this to completion IMO. Instead he assumes this third observer describes the relation between the other two as per "described by quantum mechanics".>> I'm at least sympathetic to...

My intuition (guess) on the square root in the Koide equation is that it is in the nature of waves that their energies (and therefore their masses) are proportional to the squares of their amplitudes. Here "amplitude" is something about a wave that is convenient for mathematical physicists in...

I wouldn't call relational a circular argument. It's that to have any information about a quantum state, say a particle, you need something to measure it with and that will be another quantum state or at least a system. An example is the "candle dance" where the professor holds a candle (or...

By the way, where I end up using Berry phase the most is when a spin-1/2 ket is sent around a closed path on the Bloch sphere. For example, suppose it starts at +z, then +x, then to +y then back to +z. What is the Berry phase for this path? Well it is half the surface area of the sphere cut...

Any time you are computing a Berry phase you always have an unknown 2 pi just as when you measure an angle in the real world you cannot distinguish between, say -pi and +pi, or between -pi/2 and 3 pi/2. Let me put it this way. So if you had a computer computing angles in the real world you...

My May 28 paper at Foundations of Physics moved from "reviewers assigned" to "under review" on August 1. I'm delaying writing the blog post until I find out what FoP is going to do with it. And I'm think that a better argument for why the subject is interesting would go roughly as follows: (1)...

Hmmm. Isn't Berry phase a phase and so you can add multiples of 2 pi to it? So figure out what amount a Berry phase of 2 pi is, when converted to a dipole moment, and add or subtract that amount. This is the "polarization quantum" and I suppose it is related to the unit cell volume.

I'm feeling a little better about ADE, thanks.

Re: "The viral loads seem to be similar in both cases, but the vaccinated folks just aren’t getting as sick." I'd like to hear a medical explanation for how this could possibly happen. If anything, I would think that having a high viral load and not "getting sick" would be an extremely bad...
