Message-ID: <1447@hub.ucsb.edu> Date: 10 Apr 89 16:17:16 GMT Sender: news@hub.ucsb.edu Organization: UC, Santa Barbara. Physics Computer Services Lines: 9 Debates about "analog (continuous) underpinnings" versus "digital (discrete) underpinnings cause me to wonder(rhetorically) whether the implementation of "reference" (including all of its subjacent coffee grounds) is an "important" topic. Various kinds of analytical studies (foundations of mathematics etc.) have progressed without knowing whether the coffee-grounds are analog or digital. The nature and competence of "reference" may be supported by the coffee-grounds, but not fundamentally dependent upon them. for instance, one may imagine other dustmotes where what we call a "von-neumann-machine" is the local "natural product"!!!!
