Science And Engineering Quotes (11 quotes)


A scientist can discover a new star but he cannot make one. He would have to ask an engineer to do it for him.
The Design of Design (1969), 1
Science quotes on:  |  Engineering (115)  |  Science (1699)

Engineering is quite different from science. Scientists try to understand nature. Engineers try to make things that do not exist in nature. Engineers stress invention. To embody an invention the engineer must put his idea in concrete terms, and design something that people can use. That something can be a device, a gadget, a material, a method, a computing program, an innovative experiment, a new solution to a problem, or an improvement on what is existing. Since a design has to be concrete, it must have its geometry, dimensions, and characteristic numbers. Almost all engineers working on new designs find that they do not have all the needed information. Most often, they are limited by insufficient scientific knowledge. Thus they study mathematics, physics, chemistry, biology and mechanics. Often they have to add to the sciences relevant to their profession. Thus engineering sciences are born.
Y.C. Fung and P. Tong, Classical and Computational Solid Mechanics (2001), 1.
Science quotes on:  |  Design (92)  |  Engineering (115)  |  Invention (283)  |  Science (1699)

Engineering or Technology is the making of things that did not previously exist, whereas science is the discovering of things that have long existed.
The Tower and the Bridge: The New Art of Structural Engineering (1983), 9.
Science quotes on:  |  Discovery (591)  |  Engineering (115)  |  Science (1699)  |  Technology (199)

Engineers use knowledge primarily to design, produce, and operate artifacts. … Scientists, by contrast, use knowledge primarily to generate more knowledge.
What Engineers Know and How They Know It (1990), 226. In Camilla Stivers, Democracy, Bureaucracy, and the Study of Administration (2001), 144.
Science quotes on:  |  Engineering (115)  |  Knowledge (1128)  |  Science (1699)

Put glibly:
In science if you know what you are doing you should not be doing it.
In engineering if you do not know what you are doing you should not be doing it.
Of course, you seldom, if ever, see either pure state.
In The Art of Doing Science and Engineering: Learning to Learn (1975, 2005), 5.

Science is concerned with what is possible while engineering is concerned with choosing, from among the many possible ways, one that meets a number of often poorly stated economic and practical objectives.
From Turing Award lecture (1968), 'One Man's View of Computer Science', collected in ACM Turing Award Lectures: The First Twenty Years, 1966 to 1985 (1987), 209. ACM is the Association for Computing Machinery. Also in Journal of the ACM (Jan 1969), 16, No. 1, 5.

Scientists do the work of God, engineers do the work of man.
Anonymous
In Lee Dye, 'On Science: Who Leads the Parade of Invention, Scientist or Engineer?', Los Angeles Times (3 Sep 1990) it is stated (without any quotation marks) that: A number of years ago, when Caltech planetary scientist Bruce Murray was the director of the Jet Propulsion Laboratory, he is said to have told his colleague, engineer John Casani, that scientists do the work of God; engineers do the work of man.

The engineer is concerned to travel from the abstract to the concrete. He begins with an idea and ends with an object. He journeys from theory to practice. The scientist’s job is the precise opposite. He explores nature with his telescopes or microscopes, or much more sophisticated techniques, and feeds into a computer what he finds or sees in an attempt to define mathematically its significance and relationships. He travels from the real to the symbolic, from the concrete to the abstract. The scientist and the engineer are the mirror image of each other.
In The Development of Design (1981), 19-20.

The scientist describes what is; the engineer creates what never was.
Biographical Memoirs of Fellows of the Royal Society (1980), 26, 110. As cited in Alan L. Mackay, A Dictionary of Scientific Quotations (1994), 138. (Also seen as “Scientists study/discover the world as it is, engineers create the world that never has been.”)
Science quotes on:  |  Engineering (115)  |  Science (1699)

The scientist discovers a new type of material or energy and the engineer discovers a new use for it.
The Development of Design (1981), 19.
Science quotes on:  |  Energy (185)  |  Engineering (115)  |  Science (1699)  |  Usefulness (70)

[An engineer's] invention causes things to come into existence from ideas, makes world conform to thought; whereas science, by deriving ideas from observation, makes thought conform to existence.
Types of Technology', Research in Philosophy & Technology (1978), Vol. 1, 244.
Science quotes on:  |  Engineering (115)  |  Observation (418)  |  Science (1699)  |  Thought (374)


Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
