Well, if he is a magnet guy, Florsheim still makes magnetized shoes.  You just have to special order them.  Remember these?  The ones that are supposed to break up those clumps of iron in your blood...

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.

 

Sigh

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

"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

If you wish to see an idealized version (without the
influence of the solar wind), you can use Celestia with the magnetic field
add-on.  The basic program can be found at http://www.shatters.net/celestia and the addon at http://www.celestiamotherlode.com.  There are a couple of
tweaks to the add-on that allow you to show (or not) various field lines and
particle pathways.
