Interpretation
This quote highlights the necessity of understanding in both science and engineering to ensure effective practice.
Richard Hamming articulates a crucial distinction between the fields of science and engineering, emphasizing the importance of knowledge in both areas. He suggests that true mastery involves a balance between knowing and applying knowledge, implying that both overconfidence in one's understanding and ignorance can lead to poor outcomes. The statement serves as a reminder that effective practice in these fields often requires a nuanced blend of certainty and uncertainty, pushing professionals to continuously seek deeper understanding.
In practice
This quote is perfect for a scientific seminar discussing the importance of expertise.
When you are famous it is hard to work on small problems. This is what did [Claude Elwood] Shannon in. After information theory, what do you do for an encore? The great scientists often make this error. They fail to continue to plant the little acorns from which the mighty oak trees grow. They try to get the big thing right off. And that isn't the way things go. So that is another reason why you find that when you get early recognition it seems to sterilize you.
Science is composed of laws which were originally based on a small, carefully selected set of observations, often not very accurately measured originally; but the laws have later been found to apply over much wider ranges of observations and much more accurately than the original data justified.
Does anyone believe that the difference between the Lebesgue and Riemann integrals can have physical significance, and that whether say, an airplane would or would not fly could depend on this difference? If such were claimed, I should not care to fly in that plane.
If you don't work on important problems, it's not likely that you'll do important work.
Beware of finding what you're looking for._x000D_ _x000D_ A favorite aphorism he often used.
One of the characteristics of successful scientists is having courage. Once you get your courage up and believe that you can do important problems, then you can. If you think you can't, almost surely you are not going to.
If you've been wondering where the next gold rush is going to take place, look up at the night sky to our closest celestial neighbor. The next economic boom might just be a mere 240,000 miles away on the bella luna.
Everything great in science and art is simple. What can be less complicated than the greatest discoveries of humanity - gravitation, the compass, the printing press, the steam engine, the electric telegraph?
I would never have been a good scientist - my attention span was too short for that.
Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.
Fantasy is the impossible made probable. Science Fiction is the improbable made possible.
We've learned that musical ability is actually not one ability but a set of abilities, a dozen or more. Through brain damage, you can lose one component and not necessarily lose the others. You can lose rhythm and retain pitch, for example, that kind of thing.
