Published papers may omit important steps and the memory of men of science, even the greatest, is sadly fallible.

The beauty of life is, therefore, geometrical beauty of a type that Plato would have much appreciated.

The question of the origin of life is essentially speculative. We have to construct, by straightforward thinking on the basis of very few factual observations, a plausible and self-consistent picture of a process which must have occurred before any of the forms which are known to us in the fossil record could have existed.

Scientific corporations might well become almost independent states and be enabled to undertake their largest experiments without consulting the outside world - a world which would be less and less able to judge what the experiments were about.

All that glitters may not be gold, but at least it contains free electrons.

So many of the chemical reactions occurring in living systems have been shown to be catalytic processes occurring isothermally on the surface of specific proteins, referred to as enzymes, that it seems fairly safe to assume that all are of this nature and that the proteins are the necessary basis for carrying out the processes that we call life.

The greater the man, the more he is soaked in the atmosphere of his time; only thus can he get a wide enough grasp of it to be able to change substantially the pattern of knowledge and action.
