Naively the public assumes the products of engineers arise from the scientific method, as reflected in an old joke among engineers about the relationship of science and engineering: âif itâs a success, then itâs a scientific miracle, if a disaster, then an engineering failure.â This joke highlights that successful technologies are invisible: The hallmark of good engineering is invisibility â we rarely think of our furnace, or a jetâs engine, or the purity of a pharmaceutical because the methods to manufacture all these have been honed to perfection. This, though, also hides the creative work of engineers because the public assumes the secret of engineering lies in the mastery of arcane realms of knowledge â sophisticated calculus and powerful computing science implemented by a dispassionate, almost mechanical person â yet the power of engineers to change the world lies in their method, a method used long before sophisticated mathematics and computers. This talk lifts the veil to show, in all its glory, the engineering method, which, once understood, highlights the creativity of engineers, demonstrates their work is the pinnacle of human reasoning, and lays a foundation about how to think about technology â how to decide its proper use and aid it in fulfilling its promise. Using rich examples, this talk strips bare the tools often confused for the engineering method â scientific knowledge, mathematical manipulation â to expose what lies at the heart of the method: a surprisingly simple notion called a ârule of thumb.â
