16 Oct 2021: Rediscovering Electromagnetism. Rather than jumping straight into the reparameterisation invariant action (1.14), we instead start by modifying the action (1.20). ... This time we consider the generalisation of (1.20) given by the action.

18 Oct 2021: 1.20). This is intuitive: the light is stretched by the expansion of space as it travels through it so that the observed wavelength is longer than the emitted wavelength. ... If they are emitted with frequency. ν. 1. then, from (1.20), they arrive with
