• ... that mathematician Reginald Robin Farquharson (3 October 1930 – 1 April 1973) worked on game theory because he was interested in both mathematics and politics; and that Farquharson's doctoral thesis, which analyzed voting systems, was influential when later published as Theory of Voting (Oxford: Blackwell, 1970)?

• ... that 2001: A Species Odyssey is a short documentary film about the ethical dilemma faced by two astronauts (Frank Bowman and David Poole) when they discover an alien-human hybrid child stowed away on their spaceship?

• ... that physicist and astrophysicist Robert F. Christy was distraught at the outcome of the 1954 Oppenheimer security hearing; and that when Christy encountered Edward Teller, who had testified against Oppenheimer, Christy publicly refused to shake Teller's hand?
