Science Process
What is Engineering?
 It is a great profession. There is the fascination of
watching a figment of the imagination emerge
through the aid of science to a plan on paper. Then it
moves to realization in stone or metal or energy.
Then it brings jobs and homes to men. Then it
elevates the standards of living and adds to the
comforts of life. That is the Engineer’s high
 The great liability of
the engineer
compared to men of
other professions is
that his works are out
in the open where all
can see them. His
acts, step by step, are
in hard substance.
 He cannot bury his
mistakes in the grave
like the doctors.
 He cannot argue them
into thin air or blame
the judges like the
 He cannot, like the
architects cover his
failures with trees and
 He cannot, like the
politicians, screen
his shortcomings by
blaming his
opponents and hope
the people will
 The engineer simply cannot deny he did it. If his
works do not work, he is dammed…
 On the other hand, unlike the doctor his is not a
life among the weak. Unlike the soldier,
destruction is not his purpose. Unlike the lawyer,
quarrels are not his daily bread. To the engineer
falls the job of clothing the bare bones of science
with life, comfort, and hope.
 No doubt as years go by the people forget which
engineer did it, even if they knew. Or some
politician puts his name on it. Or they credit it to
the promoter who used other people’s money…But
the engineer himself looks back at the unending
stream of goodness which flows from his successes
with satisfactions that few professions may know.
And the verdict of his fellow professionals is all the
accolade he wants.
