61.   However, the results that are generated from these models help to clarify our interpretation of real world markets, and assist us in the evaluation of their efficiency.

62.   These are particularly important when considering the likely effects within the real world.

63.   Real world monopoly is a much less precise concept than that of theory.

64.   In the real world behaviour has more complex determinants.

65.   For in the real world there is a nasty side to religion, and religious people can become ogres.

66.   Objects in the real world do not behave in such a crazy way, so the brain can safely filter out the apparent echo as background noise.

68.   But those Ks are not found in the real world.

69.   Finally, the process of reading itself involves a basic mapping between text world and real world that can be characterised as isomorphic as well.

70.   This actualisation of text structure into a dynamically perceived world of discourse involves isomorphic procedures of matching the text world with schematic knowledge about the real world.
