[CategoryQuote] ----- Warren Buffett: "Well, it may be all right in practice, but it will never work in theory." -- Warren Buffett on how the academic community regards his investment approach TrygveReenskaug: "In theory, practice is simple" Alexandre Boily: "But, is it simple to practice theory?"'' Jan L.A. van de Snepscheut and/or Yogi Berra : "In theory, there is no difference between theory and practice. But, in practice, there is." FrankWestphal: "The DifferenceBetweenTheoryAndPractice is in theory somewhat smaller than in practice." * ''(...was my signature on the usenet for many years. I know I've heard it somewhere, but I can't tell where. Does anyone know?)'' JohnCash (Of IdSoftware fame, now working at BlizzardEntertainment): "I want to move to theory. Everything works in theory." Emily Dickinson: Experiment escorts us last - / His pungent company / Will not allow an Axiom / An Opportunity DonKnuth: "Beware of bugs in the above code; I have only proved it correct, not tried it." (From his FAQ page: http://www-cs-faculty.stanford.edu/~knuth/faq.html) In Theory everything is possible; however, I live in Practice and the road to Theory has been washed out. WilliamEdwardsDeming: "Rational prediction requires theory and builds knowledge through systematic revision and extension of theory based on comparison of prediction with observation. ... It is an extension of application that discloses inadequacy of a theory, and need for revision, or even new theory. Again, without theory, there is nothing to revise. Without theory, experience has no meaning. Without theory, one has no questions to ask. Hence without theory, there is no learning." ---- In theory, the difference between theory and practice is small. In practice, the difference between theory and practice is large. ---- EditHint: there are some more quotes an DifferenceBetweenTheoryAndPractice, merge or move here?
