Re: streams and groups
Dear Al and List,
(I wrote this before I read your more recent post but I'm sending it
anyway. A little redundancy can't hurt.)
In the few times that I have given talks before an audience, a few
perplexed but polite people might applaud my presentation. Since there are
so few, I am able easily to identify the individual streams of hand claps
from the sources scattered among the audience.
As I understand the discussion here, each clap in a clapper's stream of
claps could be considered to be a group. Or is it that each clapper's
stream of claps is a group? In any case, further parsing of my applause
would reveal that every individual clap is itself composed of streams
and/or groups of smaller identifiable transient events.
But when you, Al, finish a presentation, the audience explodes with an
ovation that is a flow of hundreds of homogenized hand-clap sources. You
can no longer pick out the streams and groups. The applause you get is a
single amorphous spatially distributed stream of noise. What happened to
the groups? And is it important to know this?
