My answer to these questions issimple --- it is the art of programming acomputer. It is the art of designing efficientand elegant methods of getting a computer tosolve problems, theoretical or practical, smallor large, simple or complex. C.A.R.

Computer science is no more about computers thanastronomy is about telescopes.Edsger Dijkstra Computer science is not as old as physics; it lags by a coupleof hundred years. However, this does not mean that there issignificantly less on the computer scientist's plate than on thephysicist's: younger it may be, but it has had a far moreintense upbringing!Richard FeynmanCompSci 6 : Fall 2005August 29/30, 2005Computer Science is a young discipline First computer science department formed in 1962CompSci 6 : Fall 2005August 29/30, 2005Young People Can Have a Big Impact Who is Shawn Fanning and what did he do (19 years old)?

Theprogrammer, like the poet, works only slightly removed from pure thought-stuff.Fred
