Neutrino masses are extremely difficult to measure. While we know precisely how much an electron weighs, we have little information on the mass of its neutral partner, the electron neutrino. The same is true of the muon neutrino and tau neutrino.
In May 1983, physicists on the UA1 detector for the Super Proton Synchrotron accelerator at CERN made the first definitive observations of the Z boson.
Some days Jerry Zimmerman calmly follows his typical morning routine and joins countless other suburbanites on the road to work. Then there are the other days. Those days Zimmerman takes on an alter-persona.
Donald Glaser of the University of California, Berkeley, won a Nobel Prize for inventing the bubble chamber in 1952 as a way of detecting subatomic particles. Now a University of Chicago professor, Juan Collar, is leading the charge to make the bubble chamber cool and cutting-edge again.
A Faraday Cup is (pick one) 1) a gadget named after the great experimentalist Michael Faraday, used to measure the current of a charged-particle beam, or 2) an award that recognizes the inventors of innovative instruments for particle accelerators.
When you hear the descending flurry of 16th notes in the trumpets, you know the gamma rays are coming. They speed toward the detector in the Gamma-ray Large Area Space Telescope in chromatically harmonized notes.
