Les Hydropathes, journal du 20 mars 1879, N°5. Caricature de Charles Cros par Georges Lorin dit Cabriol.

• ... that poet and inventor Charles Cros (1 October 1842 – 9 August 9 1888) was a member of Les Hydropathes, a Parisian literary club?

• ... that mathematician Chiungtze C. Tsen (2 April 2 1898 – 1 October 1 1940) contributed to quasi-algebraic closure, proving Tsen's theorem, which states that a function field K of an algebraic curve over an algebraically closed field is quasi-algebraically closed (i.e., C1); and that this implies that the Brauer group of any such field vanishes, and more generally that all the Galois cohomology groups H i(K, K*) vanish for i ≥ 1?

• ... that scholar, priest, and physician Marsilio Ficino (19 October 1433 – 1 October 1499) wrote: "This century, like a golden age, has restored to light the liberal arts, which were almost extinct: grammar, poetry, rhetoric, painting, sculpture, architecture, music ... this century appears to have perfected astrology."?
