Famous Richard Hamming Quotes

“Education is what, when, and why to do things. Training is how to do it. Either one without the other is not of much use.”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)
Context: I am concerned with educating and not training you.... Education is what, when, and why to do things. Training is how to do it. Either one without the other is not of much use. You might think education should precede training, but the kind of educating I am trying to do must be based on your past experiences and technical knowledge.<!-- Preface

“Either you will be a leader, or a follower, and my goal is for you to be a leader.”

Richard Hamming

Preface
The Art of Doing Science and Engineering: Learning to Learn (1991)

“When you are famous it is hard to work on small problems. […] 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. […] The Institute for Advanced Study in Princeton, in my opinion, has ruined more good scientists than any institution has created, judged by what they did before they came and judged by what they did after.”

Richard Hamming

You and Your Research (1986)

“The feeling of having free will is deep in us and we are reluctant to give it up for ourselves—but we are often willing to deny it to others!”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)

“The past is… much more uncertain—or even falsely reported—than is usually recognized.”

Richard Hamming

Preface
The Art of Doing Science and Engineering: Learning to Learn (1991)

“In the long run, the methods are the important part of the course. It is not enough to know the theory; you should be able to apply it.”

Richard Hamming Quotes about mathematics

“There is no agreed upon definition of mathematics, but there is widespread agreement that the essence of mathematics is extension, generalization, and abstraction… [which] often bring increased confidence in the results of a specific application, as well as new viewpoints.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)

“The calculus is probably the most useful single branch of mathematics. …I have found the ability to do simple calculus, easily and reliably, was the most valuable part of mathematics I ever learned.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)

“Understanding the methods of calculus is vital to the creative use of mathematics… Without this mastery the average scientist or engineer, or any other user of mathematics, will be perpetually stunted in development, and will at best be able to follow only what the textbooks say; with mastery, new things can be done, even in old, well-established fields.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)

“Probability is the mathematics of uncertainty. …many modern theories have uncertainty built into their foundations. Thus learning to think in terms of probability is essential.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)

“The only generally agreed upon definition of mathematics is "Mathematics is what mathematicians do." […]
In the face of this difficulty [of defining "computer science"] many people, including myself at times, feel that we should ignore the discussion and get on with doing it. But as George Forsythe points out so well in a recent article*, it does matter what people in Washington D. C. think computer science is. According to him, they tend to feel that it is a part of applied mathematics and therefore turn to the mathematicians for advice in the granting of funds. And it is not greatly different elsewhere; in both industry and the universities you can often still see traces of where computing first started, whether in electrical engineering, physics, mathematics, or even business. Evidently the picture which people have of a subject can significantly affect its subsequent development. Therefore, although we cannot hope to settle the question definitively, we need frequently to examine and to air our views on what our subject is and should become.”

Richard Hamming

Hamming cites Forsythe, G.E., "What to do until the computer scientist comes", Am. Math. Monthly 75 (5), May 1968, p. 454-461.
One Man's View of Computer Science (1969)

“If you expect to continue learning all your life, you will be teaching yourself much of the time. You must learn to learn, especially the difficult topic of mathematics.”

Richard Hamming

Richard Hamming Quotes about science

“All of engineering involves some creativity to cover the parts not known, and almost all of science includes some practical engineering to translate the abstractions into practice.”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)

“Without real experience in using the computer to get useful results the computer science major is apt to know all about the marvelous tool except how to use it. Such a person is a mere technician, skilled in manipulating the tool but with little sense of how and when to use it for its basic purposes.”

Richard Hamming

One Man's View of Computer Science (1969)

“In forming your plan for your future you need to distinguish three different questions: What is possible? What is likely to happen? What is desirable to have happen? In a sense the first is Science… The second is Engineering.. The third is ethics, morals, or… value judgements. …you will probably have an idea of how to alter things to make the more desirable future occur …having a vision is what tends to separate the leaders from the followers.”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)

“Science and mathematics… have added little to our understanding of such things as Truth, Beauty, and Justice. There may be definite limits to the applicability of the scientific method.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)

“Much of present science rests on engineering tools, and as time goes on, engineering seems to involve more and more of the science part. …the two fields are growing together! …and now there is not enough time to allow us the leisure which comes from separating the two fields.”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)

“Science is supposed to be cumulative, not almost endless duplication of the same kind of things.”

Richard Hamming

One Man's View of Computer Science (1969)
Context: Indeed, one of my major complaints about the computer field is that whereas Newton could say, "If I have seen a little farther than others, it is because I have stood on the shoulders of giants," I am forced to say, "Today we stand on each other's feet." Perhaps the central problem we face in all of computer science is how we are to get to the situation where we build on top of the work of others rather than redoing so much of it in a trivially different way. Science is supposed to be cumulative, not almost endless duplication of the same kind of things.

“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.”

“Rigor is not a yes-no property of a proof… it is a vague standard of careful treatment that is currently acceptable to a particular group.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: When you yourself are responsible for some new application in mathematics... then your reputation... and possibly even human lives, may depend on the results you predict. It is then the need for mathematical rigor will become painfully obvious to you.... Mathematical rigor is the clarification of the reasoning used in mathematics.... a closer examination of the numerous "hidden assumptions" is made.... Over the years there has been a gradually rising standard of rigor; proofs that satisfied the best mathematicians of one generation have been found inadequate by the next generation. Rigor is not a yes-no property of a proof... it is a vague standard of careful treatment that is currently acceptable to a particular group.

“The purpose of computing is insight, not numbers.”

Richard Hamming Quotes

“Without continuous mathematics, the study of discrete mathematics soon becomes trivial and very limited. …The two topics”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: Increasingly... the application of mathematics to the real world involves discrete mathematics... the nature of the discrete is often most clearly revealed through the continuous models of both calculus and probability. Without continuous mathematics, the study of discrete mathematics soon becomes trivial and very limited.... The two topics, discrete and continuous mathematics, are both ill served by being rigidly separated.

“There is no unique, correct answer in most cases. It is a matter of taste”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: There is no unique, correct answer in most cases. It is a matter of taste, depending on the circumstances... and the particular age you live in.... Gradually, you will develop your own taste, and along the way you may occasionally recognize that your taste may be the best one! It is the same as an art course.

“Great scientists tolerate ambiguity very well.”

Richard Hamming

You and Your Research (1986)
Context: Most people like to believe something is or is not true. Great scientists tolerate ambiguity very well. They believe the theory enough to go ahead; they doubt it enough to notice the errors and faults so they can step forward and create the new replacement theory. If you believe too much you'll never notice the flaws; if you doubt too much you won't get started. It requires a lovely balance.

“There is simply too much known to continue the older approach of giving detailed results.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: We intend to teach the doing of mathematics. The applications of these methods produce the results of mathematics (which usually is only what is taught)... There is also a deliberate policy to force you to think abstractly... it is only through abstraction that any reasonable amount of useful mathematics can be covered. There is simply too much known to continue the older approach of giving detailed results.

“No vision, not much of a future.”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)
Context: In a lifetime of many, many independent choices, small and large, a career with a vision will get you a distance proportional to n, while no vision will get you only the distance √n.... the accuracy of the vision matters less than you suppose, getting anywhere is better than drifting, there are potentially many paths to greatness for you... No vision, not much of a future.

Future

“It is easy to measure your mastery of the results via a conventional examination; it is less easy to measure your mastery of doing mathematics”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: It is easy to measure your mastery of the results via a conventional examination; it is less easy to measure your mastery of doing mathematics, of creating new (to you) results, and of your ability to surmount the almost infinite details to see the general situation.

“Until we understand languages of communication involving humans as they are then it is unlikely many of our software problems will vanish.”

Richard Hamming

“The newer aspects of many fields start with the admission of uncertainty.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: Probability plays a central role in many fields, from quantum mechanics to information theory, and even older fields use probability now that the presence of "noise" is officially admitted. The newer aspects of many fields start with the admission of uncertainty.

“Euclid's postulates came from the Pythagorean theorem, not the other way around.”

Richard Hamming

The Unreasonable Effectiveness of Mathematics (1980)
Context: The idea that theorems follow from the postulates does not correspond to simple observation. If the Pythagorean theorem were found to not follow from the postulates, we would again search for a way to alter the postulates until it was true. Euclid's postulates came from the Pythagorean theorem, not the other way around.

“In the face of almost infinite useful knowledge, we have adopted the strategy of "information regeneration rather than information retrieval." …most importantly, you should be able to generate the result you need even if no one has ever done it before you”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: In the face of almost infinite useful knowledge, we have adopted the strategy of "information regeneration rather than information retrieval."... most importantly, you should be able to generate the result you need even if no one has ever done it before you—you will not be dependent on the past to have done everything you will ever need in mathematics.

Knowledge

“He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important.”

Richard Hamming

You and Your Research (1986)
Context: I noticed the following facts about people who work with the door open or the door closed. I notice that if you have the door to your office closed, you get more work done today and tomorrow, and you are more productive than most. But 10 years later somehow you don't quite know what problems are worth working on; all the hard work you do is sort of tangential in importance. He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important.

“The assumptions and definitions of mathematics and science come from our intuition”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: The assumptions and definitions of mathematics and science come from our intuition, which is based ultimately on experience. They then get shaped by further experience in using them and are occasionally revised. They are not fixed for all eternity.

“Are you sure you are not merely "programmed" in life by what by chance events happens to you?”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)
Context: When you take a course in Euclidean geometry is not the teacher putting a... learning program into you?... You enter the course and cannot do problems; the teacher puts into you a program and at the end of the course you can solve such problems.... Are you sure you are not merely "programmed" in life by what by chance events happens to you?

“Only when field maintenance is part of the original design can it be safely controlled”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)
Context: The more complex the designed system the more field maintenance must be central to the final design. Only when field maintenance is part of the original design can it be safely controlled... This applies to both mechanical things and to human organizations.

“The people at the bottom do not have the larger, global view, but at the top they do not have the local view of all the details”

Richard Hamming

The Art of Doing Science and Engineering: Learning to Learn (1991)
Context: The people at the bottom do not have the larger, global view, but at the top they do not have the local view of all the details, many of which can often be very important, so either extreme gets poor results.

“This text is organized in the "spiral" for learning. A topic… is returned to again and again”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: This text is organized in the "spiral" for learning. A topic... is returned to again and again, each time higher up in the spiral. The first time around you may not be completely sure of what is going on, but on the repeated returns to the topic it should gradually become clear. This is necessary when the ideas are not simple but require a depth of understanding...

Learning

“They are learned by the constant use of the language and cannot be taught in any other fashion.”

Richard Hamming

Methods of Mathematics Applied to Calculus, Probability, and Statistics (1985)
Context: Mathematics, being very different from the natural languages, has its corresponding patterns of thought. Learning these patterns is much more important than any particular result... They are learned by the constant use of the language and cannot be taught in any other fashion.

“Somewhere in the mid-to-late 1950s in an address to the President and V. Ps of Bell Laboratories I said, "At present we are doing 1 out of 10 experiments on the computers and 9 in the labs, but before I leave it will be 9 out of 10 on the machines". They did not believe me… by now we do somewhere between 90% to 99% on the machines… And this trend will go on!”

“If the prior distribution, at which I am frankly guessing, has little or no effect on the result, then why bother; and if it has a large effect, then since I do not know what I am doing how would I dare act on the conclusions drawn?”

Richard Hamming

“Probability is too important to be left to the experts. […] The experts, by their very expert training and practice, often miss the obvious and distort reality seriously. […] The desire of the experts to publish and gain credit in the eyes of their peers has distorted the development of probability theory from the needs of the average user. The comparatively late rise of the theory of probability shows how hard it is to grasp, and the many paradoxes show clearly that we, as humans, lack a well grounded intuition in the matter. Neither the intuition of the man in the street, nor the sophisticated results of the experts provides a safe basis for important actions in the world we live in.”

“Besides the theory there are a lot of small technical details that must be learned so well that you can recall them almost instantaneously, such as the trigonometric identities… put one part of the identity on one side of a 3 x 5 card and the other part on the other side. Using these flash cards you can, in the odd moments of your daily life, learn the mechanical parts of the course. …for this kind of low-level material many short learning sessions are much more efficient than a few long, intense ones; but this is not necessarily true for larger ideas. …most students will not use such trivial devices as flash cards; it seems to be beneath their dignity. They suffer accordingly.”
