Sigh I know that many times people have misconceptions about science and they pass this wrong information to their students, I call it "science illiteracy" and many times these students become science teachers and the domino effect continues. I teach science at the college level, to be more specific oceanography, geology and planetary science, in my classes I give a quiz about science and scientific understanding of terms and concepts and most of them still have the misconceptions about science passed from their teachers - science literacy is a must in our colleges and universities not to mention in education k-12 – Thanks for being an advocate to science literacy. Have a great day Tibi

Subject: Re: good visualizations of the Earth's magnetic field?


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.

It does not manage to lay bare the unknown, but it flaps the surrounding veils to and fro, and every so often gleams of light escape and dazzle one’s vision.”

Here are a variety of approaches to this:

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.
