Appendix III. Engineering And Time-Binding

The Arts of Engineering, by their very nature, are derived from the work
of dead men and destined to serve not only the present but the future.
They are freer than any other human activity from the errors of
intermixing dimensions and from the fallacy of belief in individualistic
accomplishment and pride. The simple steel structure of a bridge, familiar
to us in every day life, is a clear reminder to us all of the arts of
Hephaestus and the bound-up knowledge of countless generations of smiths
and mechanics, metallurgists and chemists, mathematicians and builders,
teachers and engineers who toiled for many thousands of years to make
possible the riveted steel beams which are the elements of modern
structure. These structures do not collapse unless the natural laws for
their construction are transgressed; which seldom happens--for no one is
entrusted with the work unless he has bound up in his knowledge the
accumulated experience of the past; yet the transgressors of these natural
laws are punished with all the severity of the commo
