There is only one nature - the division into science and engineering is a human imposition, not a natural one. Indeed, the division is a human failure it reflects our limited capacity to comprehend the whole.
Bill Wulf
Engineering is not merely knowing and being knowledgeable, like a walking encyclopedia engineering is not merely analysis engineering is not merely the possession of the capacity to get elegant solutions to non-existent engineering problems engineering is practicing the art of the organized forcing of technological change... Engineers operate at the interface between science and society...
Dean Gordon Brown
Engineering is the art of organizing and directing men and controlling the forces and materials of nature for the benefit of the human race.
Henry G. Stott
Engineering 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 realisation in stone or metal or energy. Then it brings homes to men or women. Then it elevates the standard of living and adds to the comforts of life. This is the engineer's high privilege.
Herbert Hoover
The cloning of humans is on most of the lists of things to worry about from Science, along with behaviour control, genetic engineering, transplanted heads, computer poetry and the unrestrained growth of plastic flowers.
Lewis Thomas
The ideal engineer is a composite ... He is not a scientist, he is not a mathematician, he is not a sociologist or a writer but he may use the knowledge and techniques of any or all of these disciplines in solving engineering problems.
N. W. Dougherty
Engineering is an activity other than purely manual and physical work which brings about the utilization of the materials and laws of nature for the good of humanity.
R. E. Hellmund
Engineering is the professional art of applying science to the optimum conversion of natural resources to the benefit of man.
Ralph J. Smith
Engineering is the practice of safe and economic application of the scientific laws governing the forces and materials of nature by means of organization, design and construction, for the general benefit of mankind.
S. E. Lindsay
Engineering is the art or science of making practical.
