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.
In August 2007, we asked readers to send photos of places their copies of symmetry have been. Here are three letters with photographic evidence of the magazine's travels.
I enjoyed seeing the confidential letter from CERN Director General Herwig Schopper to UK Prime Minister Margaret Thatcher in the Jan/Feb 08 issue of symmetry. It reminded me of a related letter.
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.
