Memory function illustrative example

In Table II we report the same illustrative example following the Gordon procedure. The convenience of the memory function method is apparent. Furthermore, the Gordon method fails unless 0, a restriction which is overcome in the memory function method. Another quite interesting P-algorithm has been provided by H ggi et al., and we refer to the original papers for illustration and discussion of stability aspects. 

A simple example will illustrate the memory function techniques of obtaining the Green s function of a non-Hermitian q[ rator. 

The similarity exhibited here between the multi-variable and the memory hierarchy formulations of the orientational problem is obviously not a general result in fact, it derives from the choice of a variable and its time derivative in the multi-variable theory. Other variations on these themes can readily be devised for example, one could couple Q, and 4 (orthogonal ized to Qj, however) (8) or one could combine higher-order memory functions with a multi-variable theory or one could couple translational and rotational variables (9), The enormous flexibility of the G,L,E, means that the intuition of the user will play a particularly significant role in determining the success of the outcome. To illustrate this point, we now briefly recapitulate how the 6,L,E, applies to a quite different orientational problem namely, anisotropic rotational diffusion (10). 

The functioning of the brain is dependent on its composition and structure that is, on the molecular environment of the mind. The presence in the brain of molecules of N,N-diethyl-D-lysergamide, mescaline, or some other schizophrenogenic substance is associated with profound psychic effects (see, for example, Woolley, 1962). Cher-kin has recently pointed out (1967) that in 1799 Humphry Davy described similar subjective reactions to the inhalation of nitrous oxide. The phenomenon of general anesthesia also illustrates the dependence of the mind (consciousness, ephemeral memory) on its molecular environment (Pauling, 1961 Miller, 1961).
