Richard Wesley Hamming foi um matemático estadunidense.

Suas contribuições na ciência da computação incluem o Código de Hamming , a Janela Hamming , Números Hamming, Pacotes de esfera ou Desigualdade de Hamming e a Distância Hamming.

Formou-se pela Universidade de Chicago em 1937, com mestrado em 1939 pela Universidade de Nebrasca e finalmente Ph.D. pela Universidade de Illinois em Urbana-Champaign em 1942. Foi professor na Universidade de Louisville durante a Segunda Guerra Mundial, que deixou para trabalhar no Projeto Manhattan em 1945, programando um dos primeiros computadores eletrônicos digitais que calculava a solução de equações dos físicos do projeto. O objetivo do programa era descobrir se a detonação de uma bomba atômica poderia incendiar a atmosfera terreste. O programa mostrou que isto não ocorreria, possibilitando o seu uso.

De 1946 a 1976 trabalhou nos Laboratórios da Bell Telephone onde colaborou com Claude Shannon. Em 1976 muda-se para a Naval Postgraduate School, onde foi professor adjunto até 1997 quando se tornou professor emérito.

Foi um dos fundadores e presidente da Association for Computing Machinery. Wikipedia

Richard Hamming: Frases em inglês

“Perhaps thinking should be measured not by what you do but by how you do it.”

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

“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?”

“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.”

“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.”

“A central problem in teaching mathematics is to communicate a reasonable sense of taste—meaning often when to, or not to, generalize, abstract, or extend something you have just done.”

“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.”

“You ought to try to make significant contributions to humanity rather than just get along through life comfortably… the life of trying to achieve excellence in some area is in itself a worthy goal… A life without a struggle on your part to make yourself excellent is hardly a life worth living. …a life without such a goal… is merely existing…”

“The methods of mathematics are the main topic of the course, not a long list of finished mathematical results with such highly polished proofs that the poor student can only marvel at the results, with no hope of understanding how mathematics is actually created by practicing mathematicians.”

“The standard process of organizing knowledge into departments, and subderpartments, and further breaking it up into separate courses, tends to conceal the homogeneity of knowledge, and at the same time to omit much which falls between the courses.”

“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.”

“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.”

“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.”

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.”

“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.”
