Less‐elusive neutrinos to look for oil and gas deposits

Four well‐known particle physicists recently went public with a far‐out scheme using high‐energy neutrinos to explore far into the depths of the Earth. The group—Alvaro De Rujula (CERN), Sheldon Glashow (Harvard), Robert R. Wilson (Columbia) and Georges Charpak (CERN)—suggested a number of such geological studies: exploration for oil, natural gas and high‐Z ores, and determination of the vertical density profile of the Earth.
