| Description | Commencing: 'You find a force repelling a body which absorbs light, thus setting up a difference of phase between the electric & magnetic oscillations...'. He posits a source and screen at each end of a tin tube, like pistons; they will be driven apart and the third law of motion is satisfied. Lodge then asks Larmor to consider when the light is on its way to the screen but has not got there - he asks where the reaction is, perhaps on the aether, like a rocket. He continues to pose resulting questions, concluding with the example of the screen was moving away at nearly the speed of light, and noting issues of absoption and emission. He asks if Larmor has some way out of this, perhaps in published papers. |
