Baltimore lectures on molecular dynamics and the wave theory of light
Lord Kelvin's Baltimore lectures on molecular dynamics and the wave theory of light, delivered at Johns Hopkins and published in London and Baltimore in 1904 for physicists and mathematics students. Line diagrams dominate: lattices of dots on intersecting circles, scalloped wave curves with arrowed rays, labelled circle constructions, plus a halftone of a wire dodecahedron model on a stand.
