October 17

Are You Sure ...

1927: Pioneering jazz drummer and theoretical physicist Albert Einstein premiers his famous "Banks of the Sane" riff at The Blue Code jazz club and software development cooperative in the Harlem district of New York City. A young Buddy Rich is in the audience. The next night, Rich will audition for the Albert Einstein Band, astounding everyone by playing "Banks of the Sane" with what Einstein will later call "note-for-note-accuracy," yet with "fresh feeling, a true spontaneous genius."

• ... that mathematician Jacques Hadamard (8 December 1865 – 17 October 1963) contributed to number theory, complex function theory, differential geometry and partial differential equations; and that Hadamard described the creative process as having four steps: Preparation, Incubation, Illumination, and Verification?

• ... that Arab members of OPEC cut production by 5% and instituted an oil embargo against Israel's allies: the United States, the Netherlands, Rhodesia, South Africa, and Portugal on October 17, 1973; and that Saudi Arabia only consented to the embargo after Nixon's promise of $2.2 billion in military aid to Israel?

• ... that astronomers Wilhelm Fabry, Michael Maestlin and Helisaeus Roeslin were able to make observations of the supernova now known as Kepler's Supernova on 9 October, but did not record the supernova; that the first recorded observation in Europe was by Lodovico delle Colombe in northern Italy on 9 October 1604; that Johannes Kepler was only able to begin his observations on 17 October while working at the imperial court in Prague for Emperor Rudolf II; and that the supernova was subsequently named after him, even though he was not its first observer, as his observations tracked the object for an entire year?
