…l of time. However, it is easily shown that there is also a second solution: x(t) = 0 for t ≤ 0 = t3 for t ≥ 0 So, determinism fails for this spring system: there is more than one Cauchy evolution for the initial conditions x = 0, t ≤ 0. It might be that the ball just sits there; or, it might be that the ball starts bouncing for times t > 0. What’s the pathology? (Left as a puzzle…) Soul Physics is authored by Bryan W. Roberts.

…dable proof in the Haag framework. Ok, that’s the background for today. Now: Question: as we move forward, and begin to adopt theories that go beyond the standard model of particle physics, will we continue to have a CPT theorem or something like it? It is widely believe that the CPT may fail in generic extensions of quantum theory. In particular, the requirement of a unitary representation of the Poincaré group is pretty strong, and may not hold…
