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
• Turbulence models are voodoo. We still don't know how to model turbulence
  --Anonymous fluid dynamicist, in 'Practical Ship Hydrodynamics', Bertram, 2000
• As the computing speed is growing rapidly we realize that there is no such other powerful engine as CFD could be for creating vast amount of useless data
  --Boyko Tchavdarov, CFD-Aided Designer
