<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Now we are talking.<br>
<br>
I suggest we convene a sub-group of computer and simulation savvy folk. That should be you, me, Stephen Leary, Nick Green, Tim Drysdale (an expert in Maxwell solutions), my friend Nick Bailey and maybe Joakim, my brothers Pete and David and any others who express
an interest.<br>
<br>
I have written (big!) computer simulation software programmes in the past, but that was to do quantum electrodynamics and quantum chromodynamics and was written in FORTRAN! Not good enough for the task in hand!<br>
<br>
Firstly need to implement a system with primitive operations which parallel the workings of the space-time algebra. Multiplications, divisions and differentiations in particular. It would be nice if such a framework existed already, but I do not think so.
Stephen has written a suite in PYTHON to deal with the multiplications, which may be a start. Not sure what is best here: C++?, Python?, Something else?<br>
<br>
Next need to devise a basis. Obvious thing is space and time and things derived from space and time. This could be the 16 Linearly independent elements or something cleverer derived from the 4-basis of space and time. I do not know how smart we can get here.
I have no expertise in object-oriented code - but these methods may be useful in describing the levels of complexity required.<br>
<br>
Following need to choose a finite element or finite difference technique, which may be tested on the subset of the Maxwell equations alone, for which there exists an extensive literature.<br>
<br>
That is only the start!<br>
<br>

as to use the Maxwell 20. Williamson does not use the imaginary quantities Barrett uses directly. Only U(1) X SU(2) symmetries are under discussion at present. No, SO(2) nor SU(3).</span><span style="color:black"></span></p>

<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">The collective body of EM only work so far is good enough and represented in good part by Maxwell's equations. (See Hurray 2010). One might say a good working
approximation. </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black"> </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">However, if one confines their work to the photon and electron, even then there are unexplained EM interactions not covered by Maxwell's equations. Aharonov-Bohm
for example. </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black"> </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">Furthermore, there is a dichotomy in approaches. The physicist tries to get at the essence of EM or E&M, usually the simplest set as presented by nature. In
order to produce predictable and repeatable results, the EM engineer needs to condition the EM in part because nature does conditioning of EM as well. </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black"> </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">I'm aware there is a correlation between the Williamson equations and Barrett's EM. The loose fit does not mean causation and is certainly not a perfect fit.
Some thought has been given to including Jefimenko's equations, but apparently, Barrett's and Williamson's equations will suffice for now.</span><span style="color:black"></span></p>

<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">The general strawdog thought of the two sets was more one of compatibility than one of rigor in that the equations were an rigorous EM-only attempt, but not
comprehensive covering every force and instead, just confined to EM, perhaps electroweak. However, what is observed in nature is not completely covered by the Maxwell set without further clarification and extensions. </span><span style="color:black"></span></p>

and the 20 equations there. Some folks are still not satisfied and back away from the vector calculus and use quaternions. </span><span style="color:black"></span></p>

<br>
</span><span style="font-family:"Helvetica Neue"; color:blue">Yes of course. The electron solution is a soliton - look at it! Yes - Aharonov Bohm is in there and much much more. All the Aharonov Bohm stuff does is insert an eA phase change - I have a set of
four coupled differential equations expressing the proper interaction of the vector potential with the spin. The full implications of all the products of the static and the dynamic are contained in Martin and my previous work on forces. Barret is not fundamental.
It is a mere detail - added in the absence of any clue of what else to do. Good man - one has to try to do something.</span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black"> </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">I'm thinking that Barrett's is currently U(1) EM X SU(2) phase. FWIW Barrett's goal is EM conditioning. So, polarization and spin need to be added. I've heard
he is working on polarization at SU(3). Nothing published so far.<br>
<br>
</span><span style="font-family:"Helvetica Neue"; color:blue">Look, Barrett has attempted, as have others (e.g. Anderson and Arthurs), to put "spin" in as an E.A and E cross A coupling. This is just one term of a full set of field-vector products. If one takes
the full set of such products in my new formalism it gives eight coupled non-linear differential equations with about a thousand terms - including all the EA terms, but lots others too. Without a proper base theory (which I hope mine is) people are stabbing
in the dark..</span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black"> </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">My conclusion there is an incompatibility between the Williamson and Barrett equations. But we don't seem far off.<br>
<br>
</span><span style="font-family:"Helvetica Neue"; color:blue">Damn right there is a difference! Barrett has (manfully) attempted to insert an extra term into another equation to see where it gets him. I have derived the whole set of new equations from first
principles and from a deeper paradigm - by putting nothing in except space, time and energy. To be clear: No U(1) (though it comes out). No SU(2) (though it comes out). No SU(3) (though that comes out too. What I have put in is an STA for space-time. That
is the Clifford-Dirac algebra Cl(1,3) (and not Cl(3,1, which is different).</span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black"> </span><span style="color:black"></span></p>
<p class="MsoNormal" style="background:white"><span style="font-family:"Helvetica Neue"; color:black">So it's back to basics and hard work on reconciling the two approaches.<br>
<br>
</span><span style="font-family:"Helvetica Neue"; color:blue">No need to reconcile anything. Barrett is attempting to put in a little something to throw light on a deep mystery (the nature of spin). Good for him. I have no need to do this because the spin term,
for me, is just a basic and necessary part of the theory of space, time and matter. I get the spin at the basic linear level - not as a non-linear product term conditioned by an extra copy of U(1). He has put in a couple of non-linear terms E.A and E x A into
a linear equation (Maxwell). Martin and I have looked at non-linear equations too (see earlier work), but these are just not the set I have proposed here, which are linear. One can make them non-linear by doing the full product GdG for example. These include
all of the EA terms Barrett used – but also far more. That that is far more complicated and an enormous distraction from the main thrust of what needs to be done! A thousand-plus terms in eight coupled non-linear equations. To keep track of these I think a
proper computer model will be required.</span><span style="color:black"></span></p>

<br>
Mu. "Putting things in" in a symptom of the current disease in physics. The first question is anyway:which SU(2)? The standard model plonks in lots of them .. spin. isospin, lepton number ... loads more. It also sticks in a U(1) and a couple of SU(3)'s (that
of "colour" and "flavour"). it is often stated that the standard model is U(1) CROSS SU(2) CROSS SU(3). Not so, It is more like U(1) EM CROSS U(1) weak CROSS SU(2) spin CROSS SU(2) ln CROSS SU(2) CROSS SU(3) flavour CROSS SU(3) colour cross ... Each time
you plonk in another a-priori "group" you add levels of complexity to the starting point, such that the standard model as it stands has about 50 of them. Also, putting in any group a-priori then removes the possibility of explaining where the group has come
from. Any time any experimentalist finds a new symmettry - whammo - some daft theorist whacks it in as a starting point. One does not want to stick them in - one wants to derive them. I get SU(2) spin out, already. Why would I ever, then, want to put it in?<br>
<br>

<br>
Had a look at the equations but I think there is a problem as you are kind of putting things in twice. The vector potential appears in my equations as a vector - you are also putting it in as a complex number - which both expands the algebra and confuses the
situation as you are using two different dimensions for the same quantity. I think the same problem exist (by the look of it) for the Barret formulation itself. There is a similar problem in Dirac QM which, famously, led Dirac into the mists of confusion as
well.<br>
<br>
Also, I see the U(1) part of what you are doing - but where is the SU(2) part?<br>
<br>
Regards, John.</span></p>
