Scientists investigate that which already is; Engineers create that which has never been.
A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.
Scientists study the world as it is, engineers create the world that never has been.
Scientists dream about doing great things. Engineers do them.
Science without religion is lame, religion without science is blind.
You cannot teach a man anything, you can only help him find it within himself.
If we knew what it was we were doing, it would not be called research, would it?
It is through science that we prove, but through intuition that we discover.
A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.
A person with a new idea is a crank until the idea succeeds.
It is really quite amazing by what margins competent but conservative scientists and engineers can miss the mark, when they start with the preconceived idea that what they are investigating is impossible.
With a new national commitment, our scientists and engineers will overcome obstacles to taking these [hydrogen fuel cell] cars from laboratory to showroom, so that the first car driven by a child born today could be powered by hydrogen, and pollution-free.
Such a system would be very, very expensive and laborious to have, given the kinds of border we have. Scientists and engineers aren't even sure they have the technology to make it work
Our journeys to the stars will be made on spaceships created by determined, hardworking scientists and engineers applying the principles of science, not aboard flying saucers piloted by little gray aliens from some other dimension.
One hears a lot of talk about the hostility between scientists and engineers. I don't believe in any such thing. In fact I am quite certain it is untrue... There cannot possibly be anything in it because neither side has anything to do with the other.
Scientists and engineers ought to stand side by side with athletes and entertainers as role models.
Great numbers of children will be born who understand electronics and atomic power as well as other forms of energy. They will grow into scientists and engineers of a new age which has the power to destroy civilization unless we learn to live by spiritual laws.
The NSF study projected a shortfall of 675,000 scientists and engineers without considering the future demand for such individuals in the marketplace. It simply observed a decline in the number of 22-year-olds and projected that this demographic trend would result in a huge shortfall. This could be termed the supply-side theory of labor market analysis. But making labor market projections without considering the demand side of the equation doesn't pass the laugh test with experts in the field.
I want to create the airplane that flies in the rarified atmosphere of Mars. This is what galvanizes a generation to want to become scientists and engineers in the first place, not we need a scientist to develop a plane that's 20 percent more fuel-efficient than the one your parents flew.
I want to emphasize in the great concentration which we now place upon scientists and engineers how much we still need the men and women educated in the liberal tradition, willing to take the long look, undisturbed by prejudices and slogans of the moment, who attempt to make an honest judgment on difficult events.
or simply:
