There's an assymetry to the form of the two Maxwell's equations shown in picture 1. While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero. This is typically explained in the following way. While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry magnetic 'charge', either don't exist, or, the energies required to create them are so high that they are exceedingly rare. That doesn't stop us from looking for them though! Keeping with the theme of Fairbank[1] and his academic progeny over the semester break, today's post is about the discovery of a magnetic monopole candidate event by one of the Fairbank's graduate students, Blas Cabrera[2]. Cabrera was utilizing a loop type of magnetic monopole detector. Its operation is in...
Those shots are great. Are larger versions available for wallpapers? I'm Commodus on Digg, so if you can shout out links to larger versions, it'd be appreciated.
ReplyDeleteSo beautiful! Awesome photos! Nothing like a mountain (or ocean) to put things into perspective. What a great place.
ReplyDeletewow! i'm blown away, I remembered my first snow experience, hehehe...
ReplyDeletevery captivating!
