[1] A former editor at Harper's, Larry
Burns, supplied the term hologramic in 1975 when I complained that
holographic disturbed me on two counts. First, a holograph is a
handwritten document, such as a will and the word evokes the wrong imagery for
a discussion of memory. Second, holographers use holographic in a
highly technical sense, and I believe they should be allowed to continue to do
so without becoming involved in whatever bitter controversy a serious theory of
neural storage may yet provoke. If I had created hologramic theory, I would
have opted for a quieter term, such as phaseogram. While I could not
keep on using holographic, I did not feel that my rhetorical license
allowed me to drop the Greek prefix holos.
[2] In most instances when I refer to someone by name, the
reader will find a reference to the person's work in the bibliography.
[3] Holos in hologram does not refer to this
distributive property-every point containing a coded version of the entire
message-but to the preservation of all the information necessary to reproduce
the precise form of the original waves. For those familiar with holography who
may wonder what happened to amplitude, see Alexander Metherell's discussion of
phase-only holograms (Metherell, 1969a). I will come back to amplitude in
Chapter 3.
