In science, principles that are taken to be
universally applicable. Laws (for instance,
Boyle's law and Newton's laws of motion) form
the basic theoretical structure of the
physical sciences, so that the rejection of a
law by the scientific community is an almost
inconceivable event. On occasion a law may be
modified, as was the case when Einstein
showed that Newton's laws of motion do not
apply to objects travelling at speeds close
to that of light.
