The elusive particles called neutrinos interact so rarely with matter that enormous volumes of water and extremely sensitive instruments are required to detect them. The oscillation of neutrinos (and hence proof that they have mass) was demonstrated recently by physicists working at the Super-Kamiokande detector in Japan and is described by Kenji Kaneyuki and Kate Scholberg in "Neutrino Oscillations." Here workers are shown cleaning the detector's 11,146 interior photomultiplier tubes during its filling in 1996.
