- It's deja-screw all over again
--Gary Montry - The world's an exciting place when you know CFD
--John Shadid - In theory, there is no difference between theory and practice. But in practice, there is
--Anonymous computer scientist - There are 3 rules to follow when parallelizing large codes. Unfortunately, no one knows what these rules are
--W. Somerset Maugham and Gary Montry - All models are wrong, but some models are useful
--George P. E. Box - Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful
--George P. E. Box - But as no two (theoreticians) agree on this (skin friction) or any other subject, some not agreeing today with what they wrote a year ago, I think we might put down all their results, add them together, and then divide by the number of mathematicians, and thus find the average coefficient of error.
--Hiram Maxim, early aeronautical designer, 1908. - As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.
-- Maurice Wilkes discovers debugging, 1949 - The purpose of computing is insight not numbers.
-- C. Hastings, 1955
