Interested readers should read Jagdish Mehrah s superb recent scientific biography of Richard Feynman [mehra94]. Chapter 24 of Mehra s book discusses Feynman s ideas about the fundamental limits of computation. 

While it cannot be said that Feynman was an advocate of CA-like field theories - Mehra reports, in fact, that Feynman was often at odds with Fredkin in their discussions about Fredkin s Digital Mechanics [mehra94] - just the fact that someone of Feynman s stature would take an active interest in such problems and be willing to stress tlie fundamental inadequacies of existing approaches to fundamental physics, was enough to emphasize that this is an interesting subject. ... 

The quote is attributed to Rolf Landauer by Mehra ([mehra94], page 540) as part of a remark Landauer made about Feynman s participation at the 1981 MIT Conference. Landauer was referring to Feynman s interest in ferreting out the connections between quantum mechanics and computation, but his sentiment could equally well be extended to encompass Feynman s deep interest in fundamental physics. 

There are however some stringent restrictions on the applicability of the adiabatic principle (Mehra and Rechenberg [1982]). Ehrenfest himself [1917] showed that it was applicable to simply periodic systems. These are systems having two or more frequencies which are rational fractions of each other. In such systems the motion will necessarily repeat itself after a fixed interval of time. Burgers [1917], a student of Ehrenfest, showed that it was also applicable...
