"When you have only one way of expressing yourself, you have
limits that you don’t appreciate. When you get a new way to
express yourself, it teaches you that there could be a third or a
fourth way. It opens up your eyes to a much broader universe."
— David Donoho

The above quote appears as the epigraph to Chapter 4,
"Beyond Wavelets," in A Primer on Wavelets  by James S. Walker
(Chapman & Hall/CRC, 1999).  It originally appeared as the
conclusion (p. 234) of "The Mathematical Microscope: Waves,
Wavelets, and Beyond," by Barbara Burke, pp. 196-235 in
A Positron Named Priscilla , National Academy of Sciences, 1994.
