Description | Includes recollections of early work on cosmic rays with special reference to theories of energy loss: 'I made a definite mistake in interpreting the penetrating cosmic rays as owing to some change of state of the penetrative particles - it was, of course, Karl (sic) Anderson who got the right answer' (see B.136-138). Blackett also makes reference to Rochester's and Butler's discovery 'that three different unstable particles were all heavy particles' (see B.42-B.46). |
