Below is a list of some of the famous quotations on CFD

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
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
