and Microsoft's latest: blame Oprah Winfrey A new book seeks to demolish the concept that computer science is rooted in mathematics and, in particular that the notion of the algorithm is fundamental to computer science. He claims that "What is essentially a discipline of pure mathematics has come to be called "the theory of computer science," and "the notion of the algorithm has been decreed to be a fundamental paradigm of computer science" However, he says this mathematical perspective "is the wrong point of view" and is asking the wrong questions. "Mathematicians and computer scientists are pursuing fundamentally different aims, and the mathematician's tools are not as appropriate as was once supposed to the questions of the computer scientist. The primary questions of computer science are not of computational possibilities but of expressional possibilities. Computer science does not need a theory of computation; it needs a comprehensive theory of process expression." This concept of 'process expression' is, he says, a common thread running through the various disciplines of computer science. "A logic circuit is an expression of a logical process; an architecture is an expression of a continuously acting process to interpret symbolically expressed processes; a program is a symbolic expression of a process; a programming language is an environment within which to create symbolic process expression; a compiler is an expression of a process that translates between symbolic process expressions in different languages; an operating system is an expression of a process that manages the interpretation of other process expressions; any application is an expression of the application process." And, he argues, important process expressions do not qualify as algorithms. "A logic circuit is not a sequence of operations. An operating system is not supposed to terminate, nor does it yield a singular solution. An operating system cannot be deterministic because it must relate to uncoordinated inputs from the outside world. Any program utilising random input to carry out its process, such...is not an algorithm." "The notion of the algorithm," he concludes "simply does not provide conceptual enlightenment for the questions that most computer scientists are concerned with."

"Computer Science Reconsidered: The Invocation Model of Process Expression" is published by John Wiley. {moscomment} Don't miss Roll your own Linux distro and
