Context: Algorithms existed for at least five thousand years, but people did not know that they were algorithmizing. Then came Turing (and Post and Church and Markov and others) and formalized the notion.

Context: We say that the string is 'random' if there is no other representation of the string which is shorter than itself. But we will say that it is 'non-random' if there does exist such an abbreviated representation.... In general, the shorter the possible representation... the less random... On this view we recognize science to be the search for algorithmic compressions.<!--Ch. 1, p. 11
