A GIFT FROM ONE NOBEL LA✨UREATE (FREDERICK REINES) TO ANOTHER (RICHARD FEYNMAN) IN THE YEAR FEYNMAN WON THE NOBEL PRIZE, 1965

Hans Bethe, the head of the Theoretical Division at Los Alamos, was so impressed with Richard Feynman and his abilities that he appoint𓆏ed him leader of the Technical Computations Group, despite him being only 25 years old ("Bethe has said that he would rather lose any two other men than Feynman from this present job [at Los Alamos]" — Robert Oppenheimer, November 4, 1943). Feynman's group was tasked with solving problems related to the calculation of critical mass for the atomic bomb.

Frederick Reines was one of the scient꧒ists who worked under Feynman in the Technical Computations Group. After the war, he would stay at Los Alamos for another 14 years𒐪. However, during a sabbatical year in 1951, he decided that he wanted to pursue more fundamental physics research, choosing to work on the direct detection of the neutrino. Up until that point, the neutrino had been a purely theoretical entity, one that had famously been postulated by Wolfgang Pauli in 1930.

Reines would go on to win the Nobel Prize in Physics in 1995 for his detection of the neutrino. 30 years earlier, however, he would present this gold-bearing rock from his neutrino lab in a gold mine in South Africa, "the deepest neutrino lab in the world," as a♒ gift to Richard Feynman in 1965, the year he won the Nobel Prize.
