We know many laws of nature and we hope and expect to discover more. Nobody
can foresee the next such law that will be discovered. Nevertheless, there
is a structure in the laws of nature which we call the laws of invariance.
This structure is so far-reaching in some cases that laws of nature were
guessed on the basis of the postulate that they fit into the invariance
structure.
A good many times I have been present at gatherings of people ... who
have ... been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and asked [if they] could describe the Second Law of Thermodynamics. The response was cold ... also negative.
Yet I was asking something which is the scientific equivalent of: Have you
read a work of Shakespeare's?
