"Computer science also differs from physics in that it is not actually a science. It does not study natural objects. Neither is it, as you might think, mathematics; although it does use mathematical reasoning pretty extensively. Rather, computer science is like engineering; it is all about getting something to do something, rather than just dealing with abstractions, as in the pre-Smith geology"
[Richard Feynman, Feynman Lectures on Computation, 1970]
"The most profound technologies are those that disappear: they weave themselves into fabric of everyday life until are indistinguishable from it"
[Mark Weiser, The Computer for the 21st Century, Scientific American , Sept. 1991]
