How useless is the word asynchronous?
Karl M. Fant, Computer Science Reconsidered: The Invocation Model of Process Expression, (Hoboken, New Jersey, Wiley Interscience, 2007).
The take away:
Mathematics is concerned with the nature of specific computations independent of how they might be expressed.
Computer Science is concerned with the nature of expression independent of what specific computations might be expressed.
The notions of mathematics are not as fundamental to computer science as is commonly supposed.
So, what are notions fundamental to computer science; a question more easily asked than answered because of the artifact quandary?
But venturing an answer anyway, we suggest that the notion of oscillations linked with completeness demanding combinational logic into a network through which wavefronts of data spontaneously flow and transform can express any desired computation natural or artificial. This website elaborates this model.
