Findings [web]
A secondary, sympathetic encyclopaedia page from a dissident-science society (an interested community, not neutral). Points it makes: - Su "died in about 2007", sourced to James Marsen; the NTHU website was taken down but survives in the Internet Archive. It says no birth date or education details are available publicly (the project folder's autobio page does give them: born 1955, NTU Ph.D. 1985 [read: Ching-Chuan Su.html]). - Lists further Su papers not in the folder: "An Ignored Mechanism for the Longitudinal Recoil Force in Railguns and Revitalization of the Riemann Force Law" (2005); "Mechanisms for the Longitudinal Recoil Force in Railguns Based on the Lorentz Force Law", IEEE Trans. Magn. 42, 2193 (2006); "Explicit Definitions of Electric and Magnetic Fields in Potentials and Derivation of Maxwell's Equations", Eur. J. Phys. 22, L5-L8 (2001); "On the Sagnac Effect in Wave Propagation", JEWA 15(7), 945-955 (2001); "Generalisation of Radar Doppler Shift ...", Electron. Lett. 36, 1812 (2000); "On the Singularity of the Static Green's Function ...", JEWA 14, 1251 (2000); APS March/April meeting talks 2000-2002. - Book: 2008, National Tsing Hua University Press, ISBN 9789574110971. - Related work: Petr Beckmann (Einstein Plus Two, 1987; journal Galilean Electrodynamics) proposed light propagating relative to the dominant local gravitational field in 1986; the wiki says Su arrived at the same postulate "apparently working independently". Whether Su knew Beckmann's work is unknown: Su's EPJC paper in the folder does not mention Beckmann (grep of the extracted text found no "Beckmann"). - Marsen presented Su's model to the CNPS on 12 June 2021 ("The Local-Ether Model - A viable alternative to Einstein's Relativity"; YouTube https://www.youtube.com/watch?v=6tbT8Wh6R24). - Wiki states Marsen suggests the Brillet-Hall 1979 residual "may already be the predicted local-ether signal".
Bearing
Claims 1, 4, 5 and the historical record. Single secondary source for the death date (via Marsen); no primary record yet.
