Indeed, indeed,....but why they mix like that.
It's even not to imply confusions.
NUCLEAR CRYOGENICS???? magnetic polarizations..........YANG !!!
beta particles ...electrons....see the cobalt for example!!!The apparatus of Ambler,Hudson,Wu ...mesures that whith He and N2.
I don't see concrete mixing of our equations,physical.How is it possible to derivate or intergrate correctly if the real physicality isn't inserted with the biggest rationality.

Hi Lawrence,
WOW! A little bit of light reading for the next time I have trouble sleeping...
I like these qubits - they are simultaineously discrete kissing-sphere particle-like and continuous string wave-like.
Ceratinly, Philip's 4 qubit is an important sub-symmetry. My models require this for icosian symmetries.
Regarding your 3 qubit idea, Could we have a 5 qubit (the NS5-brane) decomposing into a (3+2) qubit?
Have Fun!
The 4 quantum bits with an SO(8) realization have an 24-cell realization. The 24-cell is represented by the B_4 ~ SO(9), D_4 ~ SO(8) and F_4. With a part of what I am doing in this paper, in particular within the attachment, is to work out a G_2 holonomy for these quantum bits. The G_2 is the automorphism of E_8 and F_4 the centralizer. I think by this means we can push this up to the 8-qubit entanglement problem. A part of what I have laid out is what I think are some step in this direction.
The 5-qubit problem I think is outstanding, though one can derive a combination of 4-quibits into a 5. Also within an E_8 system there are two dualities that exist with respect to the Steiner system (or Hamming distance). The standard one is [3, 5, 8] and the self-dual system is [4, 4, 8] that has a Hilbert space correspondence. The Steiner system has a dual between 3 and 5, so within the E_8 system the 3-quibit subsystem is equivalent to the 5-qubit subsystem. By this is would mean that the 3-qubit system would have 5 separable states plus 3-qubits in a W or GHZ state.

Dear Lawrence,
If I recall correctly you promised to include pictures in your essay that will show how to imagine something like spacetime foam. Did I got you wrong, or did you decide to hide your colorful results?
Eckard
I guess I am not seeing on this page here where I made such a promise. I might have said something about including a picture of a tessellated AdS spacetime. This is one of MC Escher's prints, where this illustrates the lattice system on the AdS_2.

spacetime is an empty term.
time is a numerical order of change in a 4D space

The discrete nature of time might be compared to a numerical ordering. I carry this further to consider a discrete structure in general.

"AdS circlelimit.JPG" is also a nice but naked figure without an explaining legend. I have humbly to admit to be a layman who not even heard of tessellated AdS. Let me try a wild guess: In't there a Tom Essel, and could dS stand for de Sitter? A? Hm, maybe Arahonov? Anyway, a certain part of your readers would certainly appreciate at least a list of abbreviations.
Eckard
The discussion was on fractal structure. I have a bit of a crazy idea on convolving Sloan Digital Sky Survey (SDSS) data with CMB data. After Planck has done its survey I might do this. It will be interesting to see if the Hausdorff dimensions of the two structures are equal or related in some way.
The discrete group structure and cosets defines a Schottky set. The partitions of the manifold, or regions partitioned by Jordan curves, have a self similar structure, or a Moebius group realization, which makes it a Cantor type of set. The Cantor set, or "comb partition" of the interval, is an elementary form of a fractal geometry. Mandelbrot in fact found a self similar form of noise in transmission lines which had a Cantor set structure within any time interval.
If this structure is present in quantum gravity and the quantum wave function of a cosmology, then it should persist through the inflationary epoch and have signatures on the large scale. This discrete fractal structure might be the source for non-Gaussian structures in the CMB.
Cheers LC
Dear Eckard,
AdS stands for anti de Sitter space, and it is very important for the AdS/CFT correspondence. See:
http://en.wikipedia.org/wiki/Anti_de_Sitter_space
So you were close when you said "and could dS stand for de Sitter?".
Have Fun!

Dear Ray,
It happens that even the wildest guess comes close. So I will try and add one more horrible speculation: Abelian and non-abelian? I read that Abel died in a duel when he was a young man, and Christian Felix Klein was at best a baby at that time. Perhaps, Abel's symmetry was a simple one. Non-abelian sounds to a layman like me a bit like non-Euclidean, non-Newtonian, transfinite, ueberabzaehlbar, hyperreal, superluminal, postmodern, and other once excitingly modern notions.
Lawrence Crowell wrote: "Of course supersymmetry remains a hypothetical, though some signatures of it have been detected. We will have to wait for the LHC to yield such results before anything is conclusive." Here I guess: I am too old for that.
Right now my essay has been posted. I found three plausible deviations from very basic current tenets, and I tried my best to explain them as simple as possible. Nonetheless I hope for having selected the most compelling arguments.
Regards,
Eckard
After the LHC starts up at full steam in 2012 data on SUSY should start coming in. I think it likely SUSY will be found by 2015. The Higgs particle is more difficult to separate from the noise and it might take a bit longer. I think that by the end of this decade we will have MSSM data and will be working on more sublte issues of AdS~CFT and so called soft black holes with heavy ion data.
Cheers LC
Eckard,
Tesselation is a term from geometry. It approximately means the close packing of infnitely repeated shapes that completely fill the plane. Tesselation is also called tiling of the plane. Anti deSitter space is a space of constant negative curvature, i.e., hyperbolic. So when Lawrence tiles the plane in AdS, with the Escher print, one sees the Escher shapes grow infinitely small at the rim of the disc, but never disappear. It's what hyperbolic space does.

Dear Eckard,

Consider the Standard Model: SU(3)xU(1)xSU(2). SU(2) and SU(3) are considered non-Abelian because their mediating bosons can interact with one another. For instance, couplings between the W and Z exist. We even speculate on the possibility of glue-balls because three gluons could theoretically couple to one another in such a manner as to yield a net color of white. On the other hand, the U(1) of Weak hypercharge represents Electromagnetism, which is Abelian and its mediating boson, the photon, does not interact with itself at tree level (although we do have radiative corrections of order the fine-structure constant squared and smaller caused by ghost loop electrons).
Gravity is a paradox. On one hand, gravity is an inverse-radius-squared force with "infinite" range - as is Electromagnetism, and so we might expect gravity to have an Abelian nature. On the other hand, the theoretical graviton quanta interacts with mass, mass interacts with curvature, and curvature interacts with gravity, which seems non-Abelian. Perhaps the characteristics that we call "Gravity" are two different forces. I think that Edwin Klingman would be pleased with that idea...
I travelled this week and got behind on this blog site. Hopefully, I can read your essay next week.
Have Fun!
Dr. Cosmic Ray
It was Galois who died in a duel.
With quantum gravity in a QFT setting has a quadratic momentum dependence on the graviton vertex V[k] ~ k^2. This is due to the form the action takes in an expansion of the metric density {\tilde g}_{μν} = g^{1/2}g_{μν } with
{\tilde g}_{μν} = η_{μν } + κ^2{φ^α}_μ φ_{αν}.
The action L ~ κ^{-2}φi^{α μ;α}{φ_{αμ}}^{;α} gives a three point vertex function which is quadratic in the momentum.
A general Feynman diagram will also have internal lines I[k] ~ 1/k^2 and loops with L[k] ~ ∫^kd^4 p. So the internal portion of a Feynman diagram will have internal lines, vertices and loops. The Euler characteristic for a graph 1 = V[k] - I[k] + L[k] is used in conjunction with the degree of divergence of these parts of the graph D_V = 2 D_I = -2 D_L = 4 with a total divergence D = 4L[k] - 2I[k] + 2V[k], so that D = 2(L[k] + 1). Consequently the divergence has an unbounded growth with the order of each Feynman diagram.
As pointed out above the gravitational constant has units of [G] = Area, which differs from the fine structure constant α = e^2/ħc and other gauge couplings which are unitless. The dimensional content of the gravitational constant is related to the problem of quadratic vertices. The interest in holography and AdS/CFT correspondence is with how gravity in an AdS space with negative Gaussian curvature may be replaced by quantum field on the boundary. So the divergence in a naïve QFT theory of gravity may be substituted with a stringy theory on the boundary of a space where these divergences do not exist.
Cheers LC
Lawrence,
That's a lot of math to reach the strong conclusion that "there is only one electron, one proton (well really one up quark and one down quark), one photon and so forth in the entire universe, and what we see as multiple copies of them are a sort of illusion induced by a large scale decoherence and the subjective appearance of decoherent classes of histories."
Why hold back? Why not say something radical?
Have you figured out where consciousness [with or without free will] comes from in this scenario?
Also, I missed how W's and Z's fit into this scheme and the three generations. Are these included in the "and so forth"?
Edwin Eugene Klingman
The conjecture that there only exist one type of quark, or electron and the like is not substantiated as yet. The world may only have 496 bits, or eigenstates, which of course radically simplifies everything. These eigenstates are fundamental from a group theoretic perspective. The particles in these states form superpositions through a set of other states induced by spacetime. For instance a state for a quark |u> may exist in a huge number of momentum states, so |u> - -> |u>|k> = |u(k)>, such that the momentum states are a property of the emergent spacetime. So for a large number of momentum states the up quark becomes
sum_k c(k) |u(k)>
The occurrence of a vast number of particles is then due to this superposition. The path integral for these field is in line with Feynman's original idea of the path integral, where a particle traverses a path throughout the world, both forwards and backwards in time.
I am not concerned about consciousness. It is not that I regard consciousness as unimportant, but at this time I question whether we can adequately address the problem. I question the extent to which fundamental physics is able to address the question as well. So for the time I regard consciousness as an unknown which at this time I don't try to answer.
Cheers LC
Lawrence,
I really try to understand you, but I continually fail. I can't even understand your summation in your essay, as to whether you come down on the side of a discrete or continuous universe. I point out in my essay that since digital and analog filtering are equivalent, the answer cannot be mathematical, but must be answered physically.
I think that when God made your and my mind, he decided to see what orthogonal minds would look like. I think he succeeded. They both work, and they both work well, and they probably even share the same universe, but there's no overlap.
You seem to come down on both sides of the fence, and state that it will simply give philosophers a lot to do. In my essay I propose several experiments that I believe can distinguish between continuous fields and real particles. Is this just an exercise for you, or am I missing something important?
Edwin Eugene Klingman
