Episode notes
Host's Personal Break Explained
- James Fodor apologizes for the long gap between episodes and cites personal depression affecting output.
- He notes recovery and hopes to increase episode frequency going forward.
Fields Sustain Light
- Maxwell's equations predict self-sustaining electromagnetic waves that propagate even in a vacuum.
- Those waves arise because changing electric fields produce magnetic fields and vice versa, sustaining propagation.
Speed Of Light From Vacuum Constants
- The vacuum permittivity and permeability set the waves' speed as 1/√(ε0μ0), equal to light's speed c.
- This links classical electromagnetism directly to the nature of light.
