Scientists and Engineers • Scientists build to learn, engineers learn to • Computer science is no more about computers than astronomy is about build. - Fred Brooks telescopes. - Edsger Dijkstra
• Computer science is not as old as physics; it lags by a couple hundred years. However this does not mean that DkDuke a lum there is significantly less on the computer Chair of UNC’s scientist’s plate than on the physicist’s: Computer Science younger it may be, but it has had a far Department more intense upbringing! - Richard Turing Award Winner Feynman
Computer Science is a young discipline Computer Science and Programming • First computer science department formed in 1962 • Computer Science is more than programming – Called Informatics in many countries – Elements of both science and engineering – Elements of math, physics, cognitive science, music, art, and many other fields • To some ppgrogramming is an art, to others a science, to others an engineering discipline. What Is Computer Science? • What is it that distinguishes it from the C.A.R. (Tony) Hoare separate subjects with which it is related? What is the linking thread which gathers these disppgarate branches into a single discipline? My answer to these questions is • Turing Award Winner simple --- it is the art of programming a computer. It is the art of designing efficient • KihtdbQKnighted by Queen and elegant methods of getting a computer Elizabeth to sol ve probl ems, theoreti cal or practi cal , small or large, simple or complex.

Why is Programming Fun? What is Computer Science? • What delights may its practitioner expect as a • Devices reward – First is the sheer joy of making things. – Second is the pleasure of making things that are useful. – Third is the fascination of fashioning complex puzzle-like objects of interlocking moving parts. – Fourth is the joy of always learning. – Finally, there is the deli ght of workin g in such a tractable medium. The programmer, like the poet, works only slightly removed from pure thoughtstuff. Fred Brooks Who are these People?
