[Update: unfortunately, the link below was taken down before the tour, with no explanation. If anyone knows why, please let me know. Apologies to anyone who got their hopes up. I’m sure there will be other tours in the future, and I’ll try to make sure I have more stable information next time.]

Would anyone like a tour of the ATLAS and CMS experiments, the general purpose particle detectors at the Large Hadron Collider that were used to discover the particle known as the Higgs boson? A live, virtual tour is being given today (Tuesday June 11) on YouTube, https://www.youtube.com/watch?v=askq7-9CzrU, at 1700 CERN time — that’s 1600 London time, 11:00 New York time, 8:00 San Francisco time. Find out how these enormous, complex, magnificent devices are constructed, and learn how their various parts work together, 25 million times every second, to allow scientists to track the tiniest objects in the universe. Includes a Q&A at the end for participants.

  1. Dr.Strassler:
    A question, if I may, a little off topic. However, it is geared towards energy conservation. If I had two magnets, North Pole facing a South Pole, so that there is an attractive force between them. I now pull them apart, doing work separating them. After I pull them apart, they are stationary, and I would say that the mass of the system has increased, in accordance with the work I did (energy conservation). I now heat one magnet until it loses its magnetization. What can I say happened to the energy?
    1) the energy is still there, in the form of mass, but there is no longer a potential
    Would that be correct?

    1. Update: or, does the collapse of the magnetic field, due to the heating, cause the energy to be fired off in an electromagnetic wave?
