James H. Wilkinson cytaty

James Hardy Wilkinson – angielski matematyk, specjalista w dziedzinie analizy numerycznej, który wniósł istotny wkład do nauk komputerowych.

Od wczesnego dzieciństwa wykazywał uzdolnienia matematyczne. W wieku 17 lat rozpoczął studia w Trinity College na Uniwersytecie Cambridge. W 1940 r. rozpoczął pracę w dziedzinie balistyki, w 1946 r. przeniósł się do National Physical Laboratory, gdzie współpracował z Alanem Turingiem nad projektem komputerowym Pilot ACE.

Potem zainteresowania Wilkinsona skupiły się na polu analizy numerycznej, gdzie wynalazł szereg ważnych algorytmów.

W 1970 r. Wilkinson otrzymał Nagrodę Turinga za badania w dziedzinie analizy numerycznej, które ułatwiły wykorzystanie komputerów, oraz badania na polu algebry liniowej i wstecznej analizy błędów. Wikipedia

Oral history interview http://history.siam.org/wilkinson.htm by John C. Nash, SIAM History of Numerical Analysis and Scientific Computing Project http://history.siam.org/,13 July 1984
Kontekst: Very belatedly in 1947, Darwin [Sir Charles Darwin, great-grandson of the famous Charles Darwin] agreed to set up a very small electronics group [... ] It was not easy to have the imagination to foresee that computers were to become one of the most important developments of the century.

“Of course everything in computerology is new; that is at once its attraction, and its weakness.”

Some Comments from a Numerical Analyst (1971)
Kontekst: Of course everything in computerology is new; that is at once its attraction, and its weakness. Only recently I learned that computers are revolutionizing astrology. Horoscopes by computer!

“Turing had a strong predeliction for working things out from first principles, usually in the first instance without consulting any previous work on the subject, and no doubt it was this habit which gave his work that characteristically original flavor.”

Some Comments from a Numerical Analyst (1971)
Kontekst: Turing had a strong predeliction for working things out from first principles, usually in the first instance without consulting any previous work on the subject, and no doubt it was this habit which gave his work that characteristically original flavor. I was reminded of a remark which Beethoven is reputed to have made when he was asked if he had heard a certain work of Mozart which was attracting much attention. He replied that he had not, and added "neither shall I do so, lest I forfeit some of my own originality."

“Numerical analysis has begun to look a little square in the computer science setting, and numerical analysts are beginning to show signs of losing faith in themselves.”

Some Comments from a Numerical Analyst (1971)
Kontekst: Numerical analysis has begun to look a little square in the computer science setting, and numerical analysts are beginning to show signs of losing faith in themselves. Their sense of isolation is accentuated by the present trend towards abstraction in mathematics departments which makes for an uneasy relationship. How different things might have been if the computer revolution had taken place in the 19th century! [... ] In any case "numerical analysts" may be likened to "The Establishment" in computer science and in all spheres it is fashionable to diagnose "rigor morris" in the Establishment.

“In the early days of the computer revolution computer designers and numerical analysts worked closely together and indeed were often the same people. Now there is a regrettable tendency for numerical analysts to opt out of any responsibility for the design of the arithmetic facilities and a failure to influence the more basic features of software. It is often said that the use of computers for scientific work represents a small part of the market and numerical analysts have resigned themselves to accepting facilities "designed" for other purposes and making the best of them. […] One of the main virtues of an electronic computer from the point of view of the numerical analyst is its ability to "do arithmetic fast."”

Need the arithmetic be so bad!
Some Comments from a Numerical Analyst (1971)

“He [Turing] was particularly fond of little programming tricks (some people would say that he was too fond of them to be a "good" programmer) and would chuckle with boyish good humor at any little tricks I may have used.”
