Related to the ongoing thread about what is a professional...
One characteristic of many professions is the development of a
specialized language. This facilitates communication among members of
the profession and serves to exclude outsiders.
An example I just received:
"A directed graph (or equivalently its adjacency matrix A)
defines a symbolic dynamical system S_A, a shift of finite
type (SFT). In dynamics one naturally tries to categorize dynamical
invariants of SFTs (and related symbolic systems) in terms of
understandable matrix invariants of the nonnegative matrices
presenting them, and some theorem about which of those matrix
invariants can actually arise in the nonnegative case. Among some
successes,
there are difficult open problems."
[I am adjunct faculty at a regional university and thus am on their
mailing list for upcoming talks in the Distinguished Lecturer Series.
The above is the abstract of an upcoming talk.]
I would be interested in seeing your examples of an abstract for a
lecture by a professional photographer!
This thought was inspired by Bob W's recent post:
Annie Leibovitz is a really good photographer. Some of her stuff is
shit,
admittedly, but it's very accomplished shit and none of us are in
the same
league, shitwise, or even remotely close to being as good as she is
at her
best. When she keeps it simple she is superb.
