ASTROPHYSICAL
SYMMETRIES - Virginia Trimble (1996)---
Astrophysical objects, ranging from meteorites to the entire universe,
can be classified into about a dozen characteristic
morphologies, at least as seen by a blurry eye. Some patterns exist over
an enormously wide range of distance scales,
apparently as a result of similar underlying physics. Bipolar ejection
from protostars, binary systems, and active galaxies is
perhaps the clearest example. The oral presentation included about 130
astronomical images which cannot be reproduced here.
