Magnetic Monopoles… Holy *&%$!!!

It’s something most of us1 have been taught from the very beginning and take for granite from day to day…  no magnetic monopoles!  Gauss’s law for magnetism \nabla \cdot \mathbf{B} = 0 seems iconic and elegant, like one who would hold out, even until the very end in denying to give us a monopole while  \nabla \cdot \mathbf{B} \propto \rho_B seems suspicious and awkward.  In reality though I find this all thoroughly exciting2 and am contemplating throwing a party in honor of the discovery.  I must say that this is a testament to science’s pursuit to ever expand and correct itself through the scientific method.  Take a look at the nature news article for more information and links to the papers.

  1. or maybe just physicists []
  2. even surprisingly exciting []

Can you find the Apollo 12 LM?

I was sent this by a member of the LROC team.  See if you have the skills to find the LM Intrepid from Apollo 12 as this video scans across the Moon’s surface.  The video is quite beautiful and I would recommend watching in HD!
