Dr. Mitchell Feigenbaum, theoretical physicist.
When Feigenbaum began his career in the early 1970s, the term “chaos theory” did not exist. Generations of scientists dating back to Isaac Newton had worked on problems related to the predictability of complex systems, such as the orbits of the planets in the solar system. By the middle of the 20th century, physicists and mathematicians—inspired by the pioneering work of the French physicist and mathematician Henri Poincaré—had succeeded in characterizing chaotic states, often enabled by computers, by framing such questions as geometric problems. But the boundary between regular and chaotic behavior remained fuzzy, particularly as it applied to real physical systems.
Feigenbaum stepped into this foggy arena, developing methods capable of computationally modelling the period-doubling transition to chaos, which proceeds in a series of geometrically focused steps that remain similar when scaled across orders of magnitude, an example of so-called fractal geometry. He first studied a simple iterated algebraic equation known as the logistic map, and was later able to demonstrate that these steps are “universal:” all physical systems that become chaotic via this period-doubling route to chaos exhibit the same behavior. Feigenbaum also found that this behavior is determined by two universal constants, now known as the Feigenbaum constants.
Gene Pingatore, Illinois high school basketball coach. He holds the state record for most wins, but is perhaps more famous as the coach in “Hoop Dreams”.
Mickey Kapp. No, I hadn’t heard of him before, either, but the story is interesting: he was the provider of mixtapes to the astronauts through the Gemini and Apollo programs.
And it all started with José Jiménez.
At Mr. Kapp’s urging, Mr. Dana booked an appearance at the Kings Inn in Cocoa Beach, Fla., near where the astronauts trained. He usually did the astronaut bit with a straight man acting as interviewer, but for Cocoa Beach he was working alone.
“A few minutes into the routine, a guy in the front row began yelling out the straight man’s lines,” Mr. Thompson wrote. It was Mr. Shepard, who joined Mr. Dana onstage but was laughing so hard that another Mercury astronaut, Wally Schirra, who was there, took over, followed by another, Deke Slayton.
Paul Benjamin, actor. He knocked around quite a bit from the 1970s through to 2016: never did a “Mannix”, but he was in various other 70s cop shows, “Escape From Alcatraz” and was one of the guys on the corner in “Do the Right Thing”.
