  • Oppenheimer's privileged life:-


    "Cry baby scientist": What Oppenheimer the film gets wrong about Oppenheimer the man
    The so-called "father of the bomb" helped bring us prematurely into the age of existential risk.
    www.vox.com



    One would be tempted to describe J. Robert Oppenheimer as a tragic figure — that’s certainly how Christopher Nolan portrays him in the biopic Oppenheimer. The father of the atomic bomb who spent the rest of his life agonizing over what he had helped birth; the ultimate insider who was humbled and brought low; the hopeful scientist who started the nuclear arms race. But then, tragic figures don’t generally spend their retirement yachting around the Caribbean. Or maybe he was a tragic figure in the mold of Lord Byron — interestingly dark and mystical, remarkably pretty, and rich as Midas.

    Oppenheimer grew up in privilege, and remained swaddled in it for his whole life. His father immigrated to New York with nothing, and rose up to become a wealthy textile company executive. His parents spoiled their little genius. When he started a childhood rock collection, it grew to cover every surface in their apartment, which itself covered an entire floor overlooking the Hudson River. The Oppenheimers had a chauffeur, a French governess, three live-in maids and three van Gogh paintings. He corresponded with the New York Mineralogical Club, but when they invited him to speak they were surprised and delighted when he turned out to be only 12. His 16th birthday present was a 28-foot yacht (to go with the family’s 40-foot Lorelei) which he called Trimethy, after a chemical compound. As Oppenheimer remarked when he bought his first holiday home in New Mexico, the state where he would later spearhead the development of the atomic bomb: “hot dog!” ...continues.

  • The test is simple, elegant and pretty obvious in retrospect

    Yes - which is why it would also work well as a gag. It would leave other scientists mystified - and tempt them into wasting lots of time trying to figure out how he performed the calculation.


    I've worked with blast over-pressure measurements, effects, and calculations - and they can be pretty weird. The theories were still quite ropey in the 1990s (when i was last using them). And as the paper by Katz (that Alan Smith posted ) shows, the relevant theories would have been severely lacking in 1945.


    I've always liked reading about Fermi - I think he had an approach to problems that was (and is) often lacking in science. And as Alan Fletcher pointed out - anyone who could work with incomplete data, and lend his name to a particular type of problem, could be an asset to any project. But it seems he did like to "wind people up", at times ;)

    "As time has passed, more evidence has come to light of the bias and unfairness of the process that Dr. Oppenheimer was subjected to while the evidence of his loyalty and love of country have only been further affirmed," Granholm said.

    The Dark History ‘Oppenheimer’ Didn't Show
    Coming from the Congo, I knew where an essential ingredient for atomic bombs was mined, even if everyone else seemed to ignore it.
    www.wired.com

    "The colonial system built workers—or borderline enslaved people—not scholars. An American officer who traveled to the Belgian Congo described a scene he saw on his first day:

    A Congolese man in ragged shorts knelt on the ground, a Belgian officer towering over him with a chicote, a leather whip tipped with metal ends. “The whip whistled …

    Every lash was followed by a scream of agony … The black’s skin from neck to waist was a mass of blood with ribs shining through.” This, the American reported, was punishment for stealing a pack of cigarettes from a Belgian. “Welcome to the Congo,” the American was told...
