Dear all
You may have seen this before, but this link to a biblical timescale was posted on a recent discussion about catastrophic granite formation on the granite-research listserv:

Somehow I don't think so, but I haven't talked to him directly about it. All I have to go on is what my student brings back to me from her physics class... she is a double major in biology and geology, and still cannot get over the fact that this professor thinks evolution is based on "touchy-feely science and no hard facts." Right now I'm just concerned about keeping her from having a nervous breakdown or a hysterical attack of the giggles during her physics class.

I was following the informative discussion on the listserv today morning
when one of my undergraduate teaching assistants dropped by... someone in
her physics class asked the prof. a question about geomagnetic reversal,
and the professor responded that "there is no evidence of the earth's
magnetic field ever switching." My student did not know whether to laugh
or to cry... and at this point I don't know either. What makes matters
worse is that this physics professor is a "magnet guy" so his opinions will
be taken at face value in this particular respect.
This professor doesn't believe in evolution as well... somehow that doesn't
surprise me. I only hope all these visualization resources will help me
counter this misconception when these students enroll in my intro geology
course.

flaps the surrounding veils to and fro, and every so often gleams of light
escape and dazzle one's vision."

Thanks Cathy very informative and useful not just for Tom but for us as
well. Have a nice Day Tibi

"Today the human race is a single twig on the tree of life, a single
species on a single planet. Our condition can thus only be described as
extremely fragile, endangered by forces of nature currently beyond our
control, our own mistakes, and other branches of the wildly blossoming tree
itself. Looked at this way, we can then pose the question of the future of
humanity on Earth, in the solar system, and in the galaxy from the
standpoint of both evolutionary biology and human nature. The conclusion is
straightforward: Our choice is to grow, branch, spread and develop, or
stagnate and die."

Here are a variety of approaches to this:

If you wish to see an idealized version (without the influence of the solar

program can be found at http://www.shatters.net/celestia and the addon at

add-on that allow you to show (or not) various field lines and particle
pathways.
