| Description | Fitzgerald has spoken to [George Johnstone] Stoney and gives an account of his reserach on harmonics in double lines from recent papers, including in sodium. Fitzgerald notes what he attributed these to and his calculations, 'the whole thing is most interesting'. He discusses triple lines, with Stoney's ideas and Larmor's agreeing he thinks, on their being linearly related. Fitzgerald has done nothing on centrifugal force on a current during the summer, he is 'too lazy'. He originally thought this might be connected to the Hall effect, but now thinks otherwise, giving his arguments, and noting possible experimental approaches. He discusses Larmor's calculations for the effective radius of an ion, giving reasons for why he thinks it wrong. Fitzgerald notes writing to [Oliver] Heaviside about related issues and he suggested that 'all real currents are discrete' with spaces for magnetic force between lines of current, and some inertia. He continues with thoughts about infinite energy due to a steady state of an oscillatory system in a medium with a finite velocity of propagation, how this behaves, eventually believing that something might be made of his possible steady state as an explanation for gravity. |
