Jerome A. Hines (November 8, 1921 – February 4, 2003) was an American operatic bass who performed at the Metropolitan Opera from 1946 to 1987. Standing 6'6", his stage presence and stentorian voice made him ideal for such roles as Sarastro in The Magic Flute, Mephistopheles in Faust, Ramfis in Aida, the Grand Inquisitor in Don Carlos, the title role of Boris Godunov and King Mark in Tristan und Isolde.

Tullio Levi-Civita, (English: , Italian: [ˈtulljo ˈlɛːvi ˈtʃiːvita]; 29 March 1873 – 29 December 1941) was an Italian mathematician, most famous for his work on absolute differential calculus (tensor calculus) and its applications to the theory of relativity, but who also made significant contributions in other areas. He was a pupil of Gregorio Ricci-Curbastro, the inventor of tensor calculus. His work included foundational papers in both pure and applied mathematics, celestial mechanics (notably on the three-body problem), analytic mechanics (the Levi-Civita separability conditions in the Hamilton–Jacobi equation) and hydrodynamics.

Marcel Jouhandeau (July 26, 1888 Guéret – April 7, 1979) was a French writer.

Marie Ennemond Camille Jordan (French: [ʒɔʁdɑ̃]; 5 January 1838 – 22 January 1922) was a French mathematician, known both for his foundational work in group theory and for his influential Cours d'analyse.

Andrew Russell Forsyth, FRS, FRSE (18 June 1858, Glasgow – 2 June 1942, South Kensington) was a British mathematician.

The Mars effect is a purported statistical correlation between athletic eminence and the position of the planet Mars relative to the horizon at time and place of birth. This controversial finding was first reported by the French psychologist and "neo-astrologer" Michel Gauquelin. In his book L'influence des astres ("The Influence of the Stars", 1955), Gauquelin suggested that a statistically significant number of sports champions were born just after the planet Mars rises or culminates. He also divided the plane of the ecliptic into twelve sectors, identifying two "key" sectors of statistical significance.
Gauquelin's work was accepted by the psychologist Hans Eysenck among others but later attempts to validate the data and replicate the effect have produced uneven results, chiefly owing to disagreements over the selection and analysis of the data set. Since the phenomenon in question depends upon the daily rotation of the Earth, the availability and accuracy of time and place of birth data is crucial to such studies, as is the criterion of "eminence". Later research claims to explain the Mars effect by selection bias, favouring champions who were born in a key sector of Mars and rejecting those who were not from the sample.
