However this does not mean that there is significantly less on the computer scientist’s plate than on the physicist’s:scientist s plate than on the physicist s: younger it may be, but it has had a far more intense upbringing! - Richard FeynmanScientists and Engineers• Scientists build to learn, engineers learn to build. - Fred BrooksDk lDuke alum Chair of UNC’s Computer ScienceComputer Science Department Turing Award WinnergComputer Science and ProgrammingComputer Science and Programming• 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 programming is an art, to others a pg gscience, to others an engineering discipline.Computer Science is a young discipline• First computer science department formed in 1962in 1962What Is Computer Science?• What is it that distinguishes it from the separate subjects with which it is related?separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single pgdiscipline? My answer to these questions is simple --- it is the art of programming a computer. It is the art of designing efficient and elegant methods of getting a computer t l bl th ti l ti lto solve problems, theoretical or practical, small or large, simple or complex.C.A.R.
