| Description | The topics principally referred to are:
Blackett's hypothesis, as set out in his papers of 1947 and 1949 and in related talks, its reception and discussion.
Experiments arising from the hypothesis, especialy the new magnetometer and the 'White Dwarfs' experiment (C.42-C.44, see also C.13), and other possible experiments.
Later observations on geomagnetism. |
