logical
 adj.

   [from the technical term logical device, wherein a physical device is
   referred to by an arbitrary `logical' name] Having the role of. If a
   person (say, Les Earnest at SAIL) who had long held a certain post
   left and were replaced, the replacement would for a while be known as
   the logical Les Earnest. (This does not imply any judgment on the
   replacement.) Compare {virtual}.

   At Stanford, `logical' compass directions denote a coordinate system
   relative to El Camino Real, in which `logical north' is always toward
   San Francisco and `logical south' is always toward San Jose--in spite
   of the fact that El Camino Real runs physical north/south near San
   Francisco, physical east/west near San Jose, and along a curve
   everywhere in between. (The best rule of thumb here is that, by
   definition, El Camino Real always runs logical north-south.)

   In giving directions, one might say: "To get to Rincon Tarasco
   restaurant, get onto {El Camino Bignum} going logical north." Using
   the word `logical' helps to prevent the recipient from worrying about
   that the fact that the sun is setting almost directly in front of him.
   The concept is reinforced by North American highways which are almost,
   but not quite, consistently labeled with logical rather than physical
   directions. A similar situation exists at MIT: Route 128 (famous for
   the electronics industry that grew up along it) wraps roughly 3
   quarters around Boston at a radius of 10 miles, terminating near the
   coastline at each end. It would be most precise to describe the two
   directions along this highway as `clockwise' and `counterclockwise',
   but the road signs all say "north" and "south", respectively. A hacker
   might describe these directions as logical north and logical south, to
   indicate that they are conventional directions not corresponding to
   the usual denotation for those words.

   the role of.  If a person (say, Les Earnest at SAIL) who had

   Compare {virtual}.

   At Stanford, "logical" compass directions denote a coordinate
   system in which "logical north" is toward San Francisco,
   "logical west" is toward the ocean, etc., even though logical
   north varies between physical (true) north near San Francisco
   and physical west near San Jose.  (The best rule of thumb here
   is that, by definition, El Camino Real always runs logical
   north-and-south.)  In giving directions, one might say: "To
   get to Rincon Tarasco restaurant, get onto {El Camino Bignum}
   going logical north."  Using the word "logical" helps to

   A similar situation exists at MIT: Route 128 (famous for the
   electronics industry that has grown up along it) is a
   3-quarters circle surrounding Boston at a radius of 10 miles,
   terminating near the coastline at each end.  It would be most
   precise to describe the two directions along this highway as
   "clockwise" and "counterclockwise", but the road signs all say
   "north" and "south", respectively.  A hacker might describe
   these directions as "logical north" and "logical south", to
   indicate that they are conventional directions not
   corresponding to the usual denotation for those words.  (If
   you went logical south along the entire length of route 128,
   you would start out going northwest, curve around to the
   south, and finish headed due east, passing along one infamous
   stretch of pavement that is simultaneously route 128 south and
   Interstate 93 north, and is signed as such!)
