Next meeting: 6:30PM Friday, June 27, 2008 in ST256,
ST is the Charlene Nunley, Student Service Center, 7625 Fenton Street
Old humans, at the moment only old men, but we are not adverse to old
women joining us: Alan Bromborsky, Michael Brabanski, Jack Gaffey,
Walter Faust, and Harold Williams (host) and now joined by Wayne
Warren. The core group are all NCA, National Capital
Astronomers, members, but this is not about astronomy. The core
group could be described vocationally as engineers, mathematicians, and
physicist. They are all interested in the way the universe works
and how it might be modeled mathematically.
Younger humans, Montgomery College students who have attended some of
these meetings: Alpha Bada, Ian McIntire,
Lorena
Aries, Georgio Mori-Block, Ahadu Tilahun, Daman Camara, Leah Gold,
Tony Johnson, and Chris Leeney.
A group of files on Geometric
Algebra collected by Alan Bromborsky most written by others, but
some written by Alan is here. Our study guide for now is the
latest introGA11-30-2007.pdf file.
A new file in the GA-SIG directory is GAGC.pdf
and its title is "A Survey of Geometric Algebra and Geometric Calculus"
by Alan Macdonald of Luther College, Decorah, Iowa so you can see these
idea have even spread to Iowa. So it is time we caught up with
the dark side of the moon, if they know it in Iowa, where the corn
grows, then Arkansaw and Mississippi, where the cotton grows, can not
be far behind! What is it that we grow in Maryland besides
brilliant students? This document is only 26 pages long with
another 4 pages of web links and other references. It also says
on the first page:
“The principal argument for the
adoption of geometric algebra is that it provides
a single, simple mathematical framework which eliminates the plethora
of diverse
mathematical descriptions and techniques it would otherwise be
necessary to learn.”

Clifford Algebra,
Int. J. Numer. Meth. Eng. 45, 377–398.
Furthermore this is true.
Rules: Old humans pay for their meals that we order to be
delivered to the meeting room, younger humans (college students) eat
for free. Coffee and tea and sometimes cake or cookies, a
white board, computer with Internet link, and computer video
projector are in the room that we meet in.
We generally start by listen to a little music while
eating and then start studying and asking questions. Lately the
music has been by Utah
Phillips, a labor organizer, folk singer, storyteller, poet and
self-described "Golden Voice of the Great Southwest". We are
clearly corrupter's of the youth just as Socrates was. Anyone who
is free when we meet and is interested in our study of Geometric
Algebra is welcome. Many more people have been invited by a
factor of several than have ever showed up, mostly mathematics and
physics faculty from all of the campuses of Montgomery College and
students from the "Science Adventure Club" that Harold Williams is the
adviser. Currently we are learning to multiply Multivectors
(vectors) in a Linear Space (sometimes called a vector space)
over a scaler Fields
a Clifford Algebra. This has great application in engineering,
computer science (vision), and physics.
