1 It was possible to demonstrate by other methods refined structural differences among neuron types; however, proof was lacking that the quality of the impulse or its condition was influenced by these differences, which seemed instead to influence the developmental patterning of the neural circuits.
2 It may come as a shock to mathematicians to learn that the Schrodinger equation for the hydrogen atom is not a literally correct description of this atom, but only an approximation to a somewhat more correct equation taking account of spin, magnetic dipole, and relativistic effects.
3 The physicist rightly dreads precise argument, since an argument that is convincing only if it is precise loses all its force if the assumptions on which it is based are slightly changed. In contrast, an argument that is convincing though imprecise may well be stable under small perturbations of its underlying assumptions.
4 As my own studies have advanced, I have been increasingly impressed with the functional similarities between insect and vertebrate societies and less so with the structural differences that seem, at first glance, to constitute such an immense gulf between them.
5 Besides, the style of some Black novels, like Jean Toomer's Cane, verges on expressionism or surrealism, it does provide a counterpoint to the prevalent theme that portrays the fate against which Black heroes are pitted.
