The waves were battles and batles were waves. There was a lot of talk about waves in Marathon. Kelvin's vision was of waves too.
Lord Kelvin's vision was of aether.
Here is the the text from "Thinking Physics" by Lewis Epstien.
Lord Kelvin visualized all space filled with an incisible substance called aether and by means of this aether he accounted for the existence of both light and matter. At rest, aether was absoulely nothing but the empty vacuum of space. But set into vibration, the vibrations would spread through the aether like sound waves. The atoms of matter were nothing more than tiny vortices in the aether, like a smoke ring is a vortex in air. The aether was frictionless, so once set in rotation the vortices would spin and therefore hold together forever.
Yes, this is the same Kelvin for which the tempature system was named.
