Thanks to Arthur Anderson for a thoughtful note. However, I wonder if
there a ren't some semantic problems over this real museum/virtual
museum issue. He mentions using WWW to "exhibit" things that don't
involve "real" artifacts, such as the principle of "torque." It seems to
me that you "exhibit" some concepts on the printed page, in books and
magazines, with text, pictures, and diagrams, and that this is the sense
in which anything is "exhibited" on the Web: a musem "exhibit" on the
Web is more analogous to a catalog, or perhaps an illustrated exhibit
script, than it is to an actual exhibit of "real" artifacts.
