You know what it's like to get an X-ray done: you go to the doctor, get in a large machine, she puts on a lead vest, and X-rays shoot through your body, forming a picture of your skeletal structure. ...

Very interesting. Thanks Fraser. I follow the progress of the construction and testing of IceCube closely. I even read the weekly On Ice reports (http://www.icecube.wisc.edu/) during the Austral Summer. Of course, I'm really looking forward to the TeV and PeV neutrino astronomy, but this "tomography" project is a good one also.

Fraser. Interesting read. Of course the gradual improvement in neutrino detection always interests the military, as nuclear subs emit them, too. :hand:The question of neutrino masslessness is still up in the air, as ETA C always says...he is a PhD particle physicist. So far experiments only delimit the upper bounds on possible neutrino masses, and no experiment has yet been run in absentia of a matter path, where MSW oscillations are possible due to neutrino/matter interactions. pete
