• ... that theoretical physicist Max Planck (1858–1947), whose discovery of energy quanta won him the Nobel Prize in Physics in 1918, took singing lessons and played piano, organ and cello, and composed songs and operas, but chose to study physics rather than music?

• ... that inventor Edward Hebern (1869–1952) was an early designer and manufacturer of rotor encryption machines; that his implementation of his idea was less secure than he believed, because William F. Friedman found at least one method of attack when it was offered to the US Government; and that Hebern's company did not prosper, his promotional efforts for it were questioned, and he was tried and convicted for fraud?

• ... that mathematician and physicist Thomas Fincke (1561–1656) introduced the modern names of the trigonometric functions tangent and secant in his book Geometria rotundi (1583)?

• ... that computer scientist, mathematician, and rocket scientist Annie Easley (1933–2011) had a 34-year career with NASA (and its precessor) working on critical technical problems, yet despite her long career and numerous contributions to research, she was cut out of NASA's promotional photos?
