Neil Humphrey Organizes Supernova Historical Marker Dedication
On August 27th, recent graduate Neil Humphrey took part in a historical marker dedication at Headlands Beach State Park. Neil currently works as a historical researcher for the Ohio Department of Natural Resources. He organized this dedication in conjunction with the American Physical Society. This historical marker commemorated events that occurred here on February 23, 1987. That day, light emitted some 170,000 years ago from an exploding supernova (dubbed 1987A) reached earth. The Irvine Michigan-Brookhaven Detector, located some 2,000 feet below the park in the Morton Salt Mine, detected a burst of neutrinos that was verified by another detector located inside a zinc mine in Kamioka, Japan. This was the first record of interstellar neutrinos and birthed the field of neutrino astronomy. In attendance were members of the Ohio General Assembly, the U.S. Congress, and leading physicists from numerous American universities. Neil capped the ceremony off with a speech highlighting this site's importance for the histories of Ohio, the United States, the field of physics, and the global scientific community.
