Description | The numerous requests to reproduce Blackett's photographs of particle disintegration and cosmic rays (B.145-147) amply testify to the truth of the statement by E.C. Bullard (quoted by Lovell, 'P.M.S. Blackett: A Biographical Memoir', Royal Society: 1976, p9) that these photographs 'have adorned almost every text book of nuclear physics for the past fifty years'. |
