• ... that the Nth Country Experiment was an experiment conducted from 1964 to 1967 by three young physicists with no prior weapons experience to develop a working nuclear weapon design using only unclassified information with basic computational and technical support; and that, according to a heavily redacted declassified version of the summary, it was apparently judged by lab weapons experts that the team had come up with a credible design for the technically more challenging implosion style nuclear weapon; and that it is likely that the team would have been able to design a simpler gun combination weapon even more quickly, though in such a case the limiting factor in developing such a weapon is not usually design difficulty but rather the procurement of enriched uranium?

• ... that historian of mathematics Moritz Cantor (23 August 1829 – 10 April 1920) brought critical methods from other fields of history into the history of mathematics?

• ... that mathematician Oscar Chisini (14 March 1889 – 10 April 1967) posed the Chisini conjecture, a uniqueness question for morphisms of generic smooth projective surfaces, branched on a cuspidal curve; and that a special case of the conjecture is the question of the uniqueness of the covering of the projective plane, branched over a generic curve of degree at least five?

• ... that physicist and academic Giovanni Aldini (10 April 1762 – 17 January 1834) contributed to galvanism, anatomy and its medical applications, the construction and illumination of lighthouses, and the mitigation of the destructive effects of fire?
