Akebono.

He was a native Hawaiian who moved to Japan and began training in sumo.

When he became Japan’s 64th yokozuna, or grand champion sumo wrestler, in 1993, he was the first foreign-born wrestler to achieve the sport’s highest title in its 300-year modern history. He went on to win a total of 11 grand championships, and his success set the stage for an era during which foreign-born wrestlers dominated the top levels of Japan’s national sport.

…

Akebono’s rivalry with the Japanese brothers Takanohana and Wakanohana, both grand champions, was a major driver of sumo’s renewed popularity in the 1990s. During the opening ceremony for the 1998 Winter Olympics in Nagano, Japan, Akebono demonstrated the sumo ring entrance ritual for an international audience, commanding the arena with his hulking physique and captivating stare.

…

He later said in interviews that he rarely considered his nationality in the ring, thinking of himself as a sumo wrestler first and foremost. He became a naturalized Japanese citizen in 1996, and changed his name to Taro Akebono. His chosen sumo name, “Akebono,” means dawn in Japanese.

I’m a little late on this one, but everyone was on it: Peter Higgs, of Higgs boson fame.

Lawrence sent over an obit for Bruce Kessler, TV director. Before that, he raced cars:

In 1958, Kessler suffered serious injuries in a fiery crash in the middle of the night in the rain while driving a Ferrari in the 24 Hours of Le Mans (his co-driver was fellow American Dan Gurney). A year later, he spent days in a coma after a race accident in Pomona, California, then retired from the sport after yet another serious crash in 1962 in Riverside, California.

His credits as a director include “The Hat Squad”, “Renegade”, “Enos”, “The Misadventures Of Sheriff Lobo”, “Hardcastle and McCormick”…

…and the episode “Chopper” of “Kolchak: The Night Stalker”, which is my own personal favorite episode. One of these days, I’m going to write that Top Five “Kolchak” episodes list. (“Chopper”, “Firefall”, “The Sentry”…)

Finally: O.J. Simpson. THR. LAT (archived). ESPN. (Edited to add: Lawrence.)

I don’t have a lot to say about this. Whatever he did or didn’t do, he’s facing judgement for it now, and I don’t feel like making jokes.

Like buttah.

Wednesday, September 6th, 2023

The American Dairy Association North East (ADANE) has announced that the 55th Annual Butter Sculpture at the New York State Fair will be converted into energy.

Let’s think about this for a few minutes.

The linked article says the butter sculpture weighs 800 pounds. That’s probably a approximate figure, and it may be somewhat lighter or heavier. But for our purposes, let’s use the 800 pound figure. As you’ll see shortly, we’re dealing with such large numbers, a few pounds either way won’t matter.

Now, as we all know, Bob, E=MC^2. Or, energy equals mass times the square of the speed of light. So how much energy is there in 800 pounds of butter?

Freeman J. Dyson, noted physicist.

As a young graduate student at Cornell in 1949, Dr. Dyson wrote a landmark paper — worthy, some colleagues thought, of a Nobel Prize — that deepened the understanding of how light interacts with matter to produce the palpable world. The theory the paper advanced, called quantum electrodynamics, or QED, ranks among the great achievements of modern science.
But it was as a writer and technological visionary that he gained public renown. He imagined exploring the solar system with spaceships propelled by nuclear explosions and establishing distant colonies nourished by genetically engineered plants.

…

Dr. Dyson called himself a scientific heretic and warned against the temptation of confusing mathematical abstractions with ultimate truth. Although his own early work on QED helped bring photons and electrons into a consistent framework, Dr. Dyson doubted that superstrings, or anything else, would lead to a Theory of Everything, unifying all of physics with a succinct formulation inscribable on a T-shirt. In a speech in 2000 when he accepted the Templeton Prize for Progress in Religion, Dr. Dyson quoted Francis Bacon: “God forbid that we should give out a dream of our own imagination for a pattern of the world.”
Relishing the role of iconoclast, he confounded the scientific establishment by dismissing the consensus about the perils of man-made climate change as “tribal group-thinking.” He doubted the veracity of the climate models, and he exasperated experts with sanguine predictions they found rooted less in science than in wishfulness: Excess carbon in the air is good for plants, and global warming might forestall another ice age.
In a profile of Dr. Dyson in 2009 in The New York Times Magazine, his colleague Steven Weinberg, a Nobel laureate, observed, “I have the sense that when consensus is forming like ice hardening on a lake, Dyson will do his best to chip at the ice.”

He was also skeptical of the “nuclear winter” theory.

He considered himself an environmentalist. “I am a tree-hugger, in love with frogs and forests,” he wrote in 2015 in The Boston Globe. “More urgent and more real problems, such as the overfishing of the oceans and the destruction of wildlife habitat on land, are neglected, while the environmental activists waste their time and energy ranting about climate change.” That was, to say the least, a minority position.
He was religious but in an unorthodox way, believing good works to be more important than theology. “Science is exciting because it is full of unsolved mysteries, and religion is exciting for the same reason,” he said in his Templeton Prize acceptance speech. “The greatest unsolved mysteries are the mysteries of our existence as conscious beings in a small corner of a vast universe.”

…

Any advanced civilization, he observed in a paper published in 1960, would ultimately expand to the point where it needed all the energy its solar system could provide. The ultimate solution would be to build a shell around the sun — a Dyson sphere — to capture its output. Earthlings, he speculated in a thought experiment, might conceivably do this by dismantling Jupiter and reassembling the pieces.

He was also one of the folks behind Project Orion.

In the late 1970s Dr. Dyson turned full force to writing. Anyone with an interest in science and an appreciation for good prose is likely to have some Dysons on the shelf: “Disturbing the Universe,” “Weapons and Hope,” “Infinite in All Directions,” “The Sun, the Genome and the Internet.”
He also entered literature in a different way. He appeared in John McPhee’s book “The Curve of Binding Energy” (1974), a portrait of Ted Taylor, the nuclear scientist who led the Orion effort, and in Kenneth Brower’s “The Starship and the Canoe” (1978). In a memorable scene, Mr. Brower wrote of Dr. Dyson’s reunion with his son, George, who had turned his back on high technology to live in a treehouse in British Columbia and build a seafaring canoe. George Dyson later returned to civilization and became a historian of technology and an author. Dr. Dyson’s daughter Esther Dyson is a well-known Silicon Valley consultant.

Statement from the Institute for Advanced Study. This is a great line:

In 1956, Dyson began a three-year association with General Atomic, where he worked to design a nuclear reactor that would be inherently safe, or, as colleague Edward Teller put it, “not only idiot-proof, but PhD proof.”

I’m going to have to start using “PhD proof” more often in conversation.

This is eloquently stated, and seems like a good note to end on:

“No life is more entangled with the Institute and impossible to capture—architect of modern particle physics, free-range mathematician, advocate of space travel, astrobiology and disarmament, futurist, eternal graduate student, rebel to many preconceived ideas including his own, thoughtful essayist, all the time a wise observer of the human scene,” stated Robbert Dijkgraaf, IAS Director and Leon Levy Professor. “His secret was simply saying “yes” to everything in life, till the very end. We are blessed and honored that Freeman, Imme, and their family made the Institute their home. It will be so forever.”

NYT obit for Dr. Mitchell Feigenbaum. (Previously.)

L. Bruce Laingen. He was the senior diplomat in Iran during the 1979 hostage crisis, and was taken hostage.

Mr. Laingen and two aides who had been with him at the ministry remained separated from the other hostages during the long ordeal, Mr. Laingen having the odd role of continuing to act as a diplomat while being a hostage. He was a point of contact to the outside world, sometimes meeting with diplomats from other countries and even occasionally being allowed a phone call with the West.
But if he had a somewhat easier time than the hostages at the embassy, he in no way soft-pedaled his experience. In 2001, when a conservative faction in Iran set up an anti-American exhibition on the grounds of the former embassy, Mr. Laingen, in a letter to the editor printed in The Times, suggested that the site needed a plaque. He proposed this wording:
“Here is the former American Embassy in Tehran, where occurred the most egregious violation in recorded history of all standards and precepts of diplomacy: the seizure of an embassy and its staff by student terrorists, an act endorsed by their government, the hostages used as pawns for 444 days to further the political purposes of the Islamic Republic.”

…

“We are there to find out how people are thinking and why they are thinking that way and behaving that way,” he said in the oral history. “And if we get too comfortable in believing something that sort of fits our purposes, well, we are in hellish trouble.”

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”.

Sid Ramin.

Mr. Ramin (pronounced RAY-min) was one of two orchestrators — three, if you count the contributions of the composer, Leonard Bernstein, a lifelong friend — on the original Broadway production of “West Side Story,” which opened in 1957. According to “The Sound of Broadway Music” (2009), by Steven Suskin, Mr. Ramin worked on the haunting ballad “Somewhere,” the evocative “Something’s Coming,” the sweetly comic “I Feel Pretty,” the bravado-of-youth anthem “Here Come the Jets” and the irreverent “Gee, Officer Krupke.”

…

Shows whose orchestrations he worked on, in addition to “West Side Story,” included “Gypsy” (1959), “I Can Get It for You Wholesale” (1962), “A Funny Thing Happened on the Way to the Forum” (1962), Bette Midler’s “Clams on the Half Shell Revue” (1975), “Jerome Robbins’ Broadway” (1989) and “Crazy for You” (1992).
