Findings [web]

• "Electrodynamics of moving media. Report of the National Research Council Committee on Electrodynamics of Moving Media", by W. F. G. Swann, John T. Tate, H. Bateman, E. H. Kennard. Washington, D.C., National Research Council, 1922, 172 pp. Subjects: Relativity (Physics); Electrodynamics. Full view from Harvard (hvd.32044091959148), Michigan (mdp.39015069273814) and NYPL (nyp.33433084026420).

Bearing

Priority 1. This is Kennard's own later account (1922) of moving-media electrodynamics, written as a co-author with Swann and Tate. McDonald's bibliography calls Tate's 1922 chapter "a useful review" of the unipolar debates [web] files/McDonald-Faraday-disk-flux-rule.pdf. Next run: open the full view and search "unipolar", "aether"/"ether" and "Kennard".
