Part I:
John Merryman observed that "math is inherently dynamics." This reflects the essential nature of the physical world and is why physicists place such value upon finding invariances. After all, in an ever-changing universe electron and protons (left undisturbed) seem to last forever.
John asks whether there are feedback loops that are unperceived. My model of elementary particles (electron, quarks, and families) is based on such a feedback loop and I've succeeded in proving that the third order induced effect is identical to the first order inducing effect and therefore all such contributions will produce identical effects to any order. This is how stable structures can evolve and get 'locked in'.
Touching on other matters mentioned in this thread, my model predicted chiral superfluidity in RHIC collisions while Phys Rev Letters papers were predicting a 'quark gas' (2006). The flow is perfect; no cowlicks.
Lisi's E8 approach is to find a math structure and fit all known particles into it, then postulate new particles for unfilled slots. In 1979, in "The Automatic Theory of Physics" I derived a 'theory of theories' showing how a robot (programmed with the goal of acquiring data then inventing theories to describe the data) can use pattern recognition over measurement space to partition data into 'object classes' and then derive dynamical equations relating these objects. In 2009 several researchers demonstrated exactly this.
Rob Spekkens, in his winning essay, points out the essential artificial aspect of the kinematics vs dynamics "division". This is consistent with my [robot's] approach. The point is that once objects exist, observers can classify and group the objects and their translation and transformations into each other to find groups and algebras. If there is any conservation present, this is inevitable. If there is no conservation, then all is chaos. By default, we find ourself in a universe that supports such group and algebraic representations. Rick Lockyer shows how R, C, H, and O algebras can represent all of the work, energy , and other conservation laws or relations. I do not find it surprising that there are a limited number of such physical conservation laws, nor that the appropriate mathematical representations reflect these limits. Any other result *would* be surprising.
Rick states a key fact: "the 8D stuff cleanly partitions into the sum of what looks like 2 4D similar structures." In my model these are electromagnetism and gravitomagnetism (linearized Einstein equations). That's all we need! Michael argues with SU(3) color symmetry (vs Spin(3)) but accepts the 'reality' of color. My model replaces color with gravitomagnetism (retaining SU(3) symmetry) -- significantly reducing the dimensionality of it all. (Sorry, no 11D). The model supports SU(3)xSU(2)xU(1). And QCD has been moving in my direction over the last decade, not vice versa. (See 'Chromodynamics War') [Caveat: the Higg's, if really spin zero, is still a burr under my saddle.]
Joy has staked a lot on his exploding balls and Michael on Spin(3) vs SU(3). I believe both are wrong and it is good that they recognize the existence of tests of these issues. I agree with Michael that it's mistaken to perceive a "switch in description from discrete particles to continuous particle fields - in order to describe the wave particle duality." This is a problem with representation, not with reality. He is "primarily concerned with the difference between the description of reality and reality itself." In three essays I've tried to summarize a theory based on the evolution of one thing, the primordial gravitational field continuum, with it's implied quantum constraint on action, and to show how stable particles evolve with accompanying induced 'wave' and the inherent relation of this to probability. It's *not* 'wave' versus 'particle'. And it doesn't require color, but does include SU(3), SU(2), and U(1).
It's not enough to put things in 'slots'; one should show in detail the dynamical evolution of the predecessor 'thing' into the 'slot-filling' thing --show how the field evolves in continuous fashion into a particle and how particles can evolve into other particles, under appropriate circumstances. I say *the* field versus the QFT practice of inventing a new field for every new particle. QFT's use of fermion fields and 'creation and annihilation operators' is simply a sophisticated version of 'abra-cadabra' and 'presto-chango'. It's also necessary to explain why three families exist, and no more. And how and where the fine structure constant comes into play. And, given electron mass, how other masses can be calculated.
And "reading off the SM chiral particles existing in spacetime with spin 1/2 against the structure..." of the appropriate mathematical structure, is 'slot-filling', not physics. It's inconceivable to me that physically real structures and relations would exist as 'territory' without a corresponding mathematical 'map'. The map does not 'cause' the territory, it simply describes it. It is a shadow, showing only the outline of reality -- no mass, spin, charge, force or energy -- just description.
I see the goal as the derivation of a physical evolution of the world, and the creation of maps that represent the relevant symmetry/conservation relations as opposed to mathematically finding lots of slots and fitting 'things' [fully formed, not evolved!] into them.
In Part II I discuss the related issue of nonlocality.
