Abstract :
Lately one hears a great amount of criticism of the technical community because it so seldom expresses an opinion unequivocally. What the lawmakers need, we are told, is a clear cut yes or no from the experts on questions involving permitting the Concorde into the U.S., or proceeding at full speed in constructing nuclear power plants. Engineers (or scientists) must ¿speak with one voice,¿ we are told.
