Yes.  The world is a continuum.  We can name some discrete points, but
we can't describe a continuum with any set of discrete identifiers.
Some insights can be described in words, but there are too many
subtle variations -- uncountably many.    (04)

There is no proof, but there is a simple explanation.  In every field,
the practitioners name the things and methods they use and produce.
The novices learn and use the same words and syntax.    (07)

Symbols like '+' are abbreviations for the words or phrases.  Some 
diagrams are designed to be translated to and from discrete symbols.
But no words can describe a complex image -- such as a human face.    (09)

There's a big difference between "conjuring up" and specifying.    (011)

Just consider any profession from cooking to music to nuclear physics.
Two cooks can follow the same recipe and get wildly different results.
Jascha Heifetz and the kid next door can play the same notes, but
there's a world of difference in the results.    (012)

In physics, experimenters have to deal with the full continuum of
pesky details that theoreticians ignore.  George Gamow told the
following anecdote about Wolfgang Pauli:    (013)
