"[Computer science] is not really about computers -- and it's not about computers in the same sense that physics is not really about particle accelerators, and biology is not about microscopes and Petri dishes...and geometry isn't really about using surveying instruments. Now the reason that we think computer science is about computers is pretty much the same reason that the Egyptians thought geometry was about surveying instruments: when some field is just getting started and you don't really understand it very well, it's very easy to confuse the essence of what you're doing with the tools that you use."

Surveying the shifts of interest among computer scientists and the ever-expanding family of those who depend on computers for their work, one cannot help being struck by the power of the computer to bind together, in a genuine community of interest, people whose motivations differ widely.

 
Maurice Wilkes
 

Euclidean geometry can be easily visualized; this is the argument adduced for the unique position of Euclidean geometry in mathematics. It has been argued that mathematics is not only a science of implications but that it has to establish preference for one particular axiomatic system. Whereas physics bases this choice on observation and experimentation, i.e., on applicability to reality, mathematics bases it on visualization, the analogue to perception in a theoretical science. Accordingly, mathematicians may work with the non-Euclidean geometries, but in contrast to Euclidean geometry, which is said to be "intuitively understood," these systems consist of nothing but "logical relations" or "artificial manifolds". They belong to the field of analytic geometry, the study of manifolds and equations between variables, but not to geometry in the real sense which has a visual significance.

Computer Science is no more about computers than astronomy is about telescopes.

 
Edsger W. Dijkstra
 

"More than a decade will pass before personal computers emerge from the garages of Silicon Valley, and a full thirty years before the Internet explosion of the 1990s. The word computer still has an ominous tone, conjuring up the image of a huge, intimidating device hidden away in an overlit, air-conditioned basement, relentlessly processing punch cards for some large institution: them.
Yet, sitting in a non-descript office in McNamara's Pentagon, a quiet forty-seven-year-old civilian is already planning the revolution that will change forever the way computers are perceived. Somehow, the occupant of that office - a former MIT psychologist named J. C. R. Licklider - has seen a future in which computers will empower individuals, instead of forcing them into rigid conformity. He is almost alone in his conviction that computers can become not just superfast calculating machines, but joyful machines: tools that will serve as new media of expression, inspirations to creativity, and gateways to a vast world of online information. And now he is determined to use the Pentagon's money to make that vision a reality...."

Lick had this concept of the intergalactic network which he believed was everybody could use computers anywhere and get at data anywhere in the world. He didn't envision the number of computers we have today by any means, but he had the same concept-all of the stuff linked together throughout the world, that you can use a remote computer, get data from a remote computer, or use lots of computers in your job. The vision was really Lick's originally. None oof us can really claim to have seen that before him nor{can} anybody in the world. Lick saw this vision in the early sixties. He didn't have a clue how to build it. He didn't have any idea how to make this happen. But he knew it was important, so he sat down with me and really convinced me that it was important and convinced me into making it happen
