What is Computer Science?
Computer Science is the study of computers (??)
This leaves aside the theoretical work in CS, which does not make use of real computers, but of formal models of computers
A lot of work in CS is done with pen and paper!
Actually, the early work in CS took place before the development of the first computer
Computer Science is no more about computers than astronomy is about telescopes, biology is about microscopes, or chemistry is about test tubes. Science is not about tools. It is about how we use them, and what we find out we can do.
