Feb. 9, 1870: Feds Get on Top of the Weather

Busted more than once.
Skulls in the Stars: Mythbusters were scooped — by 130 years! (Archimedes death ray)
About the same time, however, and in an earlier volume of the Proceedings, I found an article with the title, “On the burning mirrors of Archimedes, and on the Concentration of light produced by reflectors,” by John Scott. [...]

Skulls in the Stars: Lord Kelvin vs. the Aether! (1901)
