25. Favorite quotes • Sufficiently advanced technology is indistinguishable from magic • An engineer can always befuddle a financial person with technology, but a financial person can never over whelm an engineer with numbers mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

26. Favorite quotes • The more you know, the better engineer you will be! • I knew then as I can confirm now, nothing would ever be as hard to understand as transport phenomena and the Navier-Stokes equations. I was never again intimidated by quantitative problems and I appreciated the need to formulate simpler problems that gave useful results. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

27. Favorite quotes The history of modern science has shown repeatedly that a quantitative description of nature can often be achieved most successfully by first idealizing natural phenomena, i.e. by setting up a simplified model, either physical or mathematical, which crudely describes the essential behavior while neglecting details. (In fact, one of the outstanding characteristics of great contributors to modern science has been their ability to distinguish between what is essential from what is incidental) ........" mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

28. Who said them • A top design engineer from DuPont • A CEO of a steel company • One of the most influential chemical engineering professors of all time • A top research/technology engineer from Shell • An ND Cheg Alum who is a VP for General Mills mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

29. Conclusions • Fluid mechanics is fun! • The niche for chemical engineers is understanding the effects of small scale phenomena that cause large scale outcomes • This course possesses great depth and should be useful to your educational development even if you do not use it day to for a living mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept
