#### BELIEVE ME NOT! **-** **-** A SKEPTIC's GUIDE

** Next:** Arithmetic

Soon we will tackle the problem of *measurement*,
with all its pitfalls and practical tricks. You may then
sympathize with Newton, who took such delight in retreating
into the Platonic ideal world of pure mathematics, where
relationships between "variables" are not fraught with
messy errors, but defined by simple and elegant prescriptions.
No matter that we are unable to measure these perfect
relationships directly; this is merely an unfortunate consequence
of our imperfect instruments. (Hmmm . . . . )
But first we need to describe the notational conventions
to be used in this book for the language of Mathematics,
without which Physics would have remained mired in the
rich but confusing ambiguities of natural language.
Here is where we assemble the *symbols* into *structures*
that express (in some conventional idiom)
the *relationships* between the "things"
the symbols represent.

Please do not feel insulted if the following review
seems too elementary for someone at your level.
I have always found it soothing to review material
that I already know well, and am usually surprised
to discover how much I forgot in such a short while.
Also, I think you'll find it picks up a bit later on.
