Physicists Uncover Strange Numbers in Particle Collisions

Hadron Collider in Geneva, physicists shoot protons around a 17-mile track and smash them together at nearly the speed of light. It’s one of the most finely tuned scientific experiments in the world, but when trying to make sense of the quantum debris, physicists begin with a strikingly simple tool called a Feynman diagram that’s not that different from how a child would depict the situation.

OK, from our point of view, one iteration of the Feynman summation is one queue rotation on the graph between bid,ask and pit boss.   The trading pit is a self organizing Monte Carlo integration, just like Feynman.

The second limitation is of a more fundamental nature. Feynman diagrams are based on the assumption that the more potential collisions and sub-collisions physicists account for, the more accurate their numerical predictions will be. This process of calculation, known as perturbative expansion, works very well for particle collisions of electrons, where the weak and electromagnetic forces dominate. It works less well for high-energy collisions, like collisions between protons, where the strong nuclear force prevails. In these cases, accounting for a wider range of collisions—by drawing ever more elaborate Feynman diagrams—can actually lead physicists astray.
 Monte Carlo relies on a good measure of dF and F as that gets the 'spacing' or step size that minimizes round off error.  But let's cut to the chase.  This whole area is exciting because we see the convergence of Ito theory, number theory, conbinatorics, and Newton's gramar.

The trading pit is exciting becaue he pit boss rules are observable, and can be modifies by consent.  But, even more importantly, the natural process and the mathematical modelers are one in the samr.  Simply from the pointy of view of entertainment, they are stuck in the maximum entropy channel, they have no choice, invent a theory of operation.
