FUN FACT!

the first ever hydrogen bomb detonated (Operation Ivy: Shot Mike) completely vaporized the island it was detonated on, leaving a giant undersea crater in its place. there was an island there, and now it's just fucking gone.

The island was Elugelab in the Enewetak Atoll

Before the Ivy Mike test:

After the Ivy Mike test:

the thing about the Ivy Mike test, though, is that the bomb was too big, impractical, and heavy to carry in an airplane, afix to a rocket, or fire from a canon. still, the blast had a yield of 10.4 megatons, rivaled only by the infamous Castle Bravo test (US 15 megatons), the B-41/ Mk-41 Bomb ( US 25 megatons), and the Tsar Bomba test (USSR 50 megatons).

The rest of these bombs can be dropped from airplanes. The Tsar Bomba design was, however, never put into production as a practical weapon and was simply intended to be a one-off exercise with the goal of creating the largest yeild atomic weapon in history. (it succeeded)

The "Baker" explosion, part of Operation Crossroads, a nuclear weapon test by the United States military at Bikini Atoll, Micronesia, on 25 July 1946. The wider, exterior cloud is actually a condensation cloud caused by the Wilson chamber effect, and was very brief. The actual mushroom cloud is inside the condensation cloud. The water released by the explosion was highly radioactive and contaminated many of the ships that were set up near it. Some were otherwise undamaged and sent to Hunter's Point in San Francisco, California, United States for decontamination. Those which could not be decontaminated were sunk a number of miles off the coast of San Francisco.

Don’t forget the first victims when you go see Oppenheimer this opening weekend. Unforgivable not to include them in the narrative.

We love us some Nolan and Cillian but this is also a story that should never have taken place.

For further reading:

This is what happens when the US government goes nuclear-crazy during the Cold War and mines a shit ton of uranium. Lambs born with three legs and no eyes, and human stillbirths and agonizing deformities for those that survive. For decades it was referred to as a Navajo-specific hereditary illness. No one made the link to the mines and the drinking water.

There is a golden spike hiding in a rock face outside the village of Moffat in Scotland that marks the end of the Ordovician, denoted by the appearance of these graptolite survivors—Akidograptus ascensus and Parakidograptus acuminatus, to give them their scientific names. It's not a real golden spike but a line of darker shale and a marker of these graptolites' significance as what's called an index fossil: Wherever such a fossil is found a geologist can be sure those rocks are of a certain age.

We have found the perfect marker for the Anthropocene, or the new epoch of humans, so dubbed for Homo sapiens’s world-changing impacts. It's a rather precise start date, thanks to some unusual isotopes: July 16, 1945, at 5:29 in the predawn New Mexico desert. That's when U.S. scientists exploded the world's first atomic bomb and when the human-induced radioactive isotope clock started ticking.

The three isotopes in question are cesium 137 and plutonium 239 and 240, which will take millennia or more to decay. There are no known natural sources of cesium 137. As a result of the subsequent detonations of hundreds of such weapons around the globe, there will be plenty of these isotopes still around far into the future. Like the meteorite that helped end the Cretaceous period about 65 million years ago, and possibly the reign of the dinosaurs as well, the nuclear detonation may mark for future geologists a turning point in Earth's history.

“If it was done for science and the availability to the rest of the human race to know that, uh, that we don’t need it. It’s way too devastating. If you could just see the colours, if you could just hear it, hear it, not on the television or in the movie, but the actual thing, I think you would agree with me. Whoever is listening to this.”

Just saw someone on Twitter complain about the lack of Japanese people in Oppenheimer, and what did you expect??? Did you want the final act to be the bomb dropping and see people burning alive???

The reason why we don't see a Japanese perspective is because one, including a Japanese perspective, just to see how bad the suffering was would be exploitation. Two, to see an accurate and sensitive take on how the japanese felt about Oppenheimer, Christopher Nolan (as incredible as he is) isn't the right person to do this. And three, it's based on Oppenheimer's biography

Oppenheimer, the movie, literally shows you people (mostly the superiors, because by the middle/end of it you see Oppenheimer regretting his creation) doing something dubious and inhumane because they removed themselves away, both emotionally and physically, from the people they are hurting.

Nagasaki and Hiroshima only exist in those men's distant thoughts and imaginations. One guy literally asks to take a city off the bombing because that's where he had his honeymoon. It's disturbing and unsettling, as if those people were not real human beings. The lack of Japanese people drives the entire point home.

Also, Japanese cinema is right there. Barefoot Gen, Grave of the Fireflies, or Hiroshima (responsible for showing to many Americans the effects of the bombs for the first time) are just a few of the many, many decades of post-war Japanese movies we have

#important to say this just my opinion and im more than glad to talk and discuss about it #also i dont think a single person left this movie thinking Oppenheimer was the greatest person ever or left as a pro atomic bomb #you could literally feel the entire room's tension after the trinity test scene and what that meant when they succeeded #as the movie ended almost everyone was in silence i left that room in complete silent #its also important to say that although i do say the scientists didn't thought about the suffering japanese people would go through #this is more a dig forwards the superiors not the scientists because a lot of the scientists (Oppenheimer included) were jewish #so they were creating that people with the sole purpose of stoping the nazis and not hurt civilians #also to the people that keep saying 'oh what was japan doing/dont act like japaneses were innocent' dude i get what youre saying #but do you honestly believe all those civilians deserved that??? they were civilians not all of them agreed to what was happening #oppenheimer #oppenheimer 2023 #barbenheimer #christopher nolan #cilian murphy

Just saw Oppenheimer and I was a bit disappointed with how they portrayed Truman. He came across pretty poorly IMO. It was only one scene but I wondered what you thought.

I understand your disappointment and it certainly wasn't a very in-depth portrayal of Truman, but according to the book that the movie was largely based on -- American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin (BOOK | KINDLE | AUDIO) -- the meeting that Oppenheimer had with President Truman went down pretty much as depicted in the film.

As Bird and Sherwin write in American Prometheus:

(O)n October 25, 1945, Oppenheimer was ushered into the Oval Office. President Truman was naturally curious to meet the celebrated physicist, whom he knew by reputation to be an eloquent and charismatic figure. After being introduced by Secretary [of War Robert P.] Patterson, the only other individual in the room, the three men sat down. By one account, Truman opened the conversation by asking for Oppenheimer's help in getting Congress to pass the May-Johnson bill, giving the Army permanent control over atomic energy. "The first thing is to define the national problem," Truman said, "then the international." Oppenheimer let an uncomfortably long silence pass and then said, haltingly, "Perhaps it would be best first to define the international problem." He meant, of course, that the first imperative was to stop the spread of these weapons by placing international controls over all atomic technology. At one point in their conversation, Truman suddenly asked him to guess when the Russians would develop their own atomic bomb. When Oppie replied that he did not know, Truman confidently said he knew the answer: "Never." For Oppenheimer, such foolishness was proof of Truman's limitations. The "incomprehension it showed just knocked the heart out of him," recalled Willie Higinbotham. As for Truman, a man who compensated for his insecurities with calculated displays of decisiveness, Oppenheimer seemed maddeningly tentative, obscure -- and cheerless. Finally, sensing that the President was not comprehending the deadly urgency of his message, Oppenheimer nervously wrung his hands and uttered another of those regrettable remarks that he characteristically made under pressure. "Mr. President," he said quietly, "I feel I have blood on my hands." The comment angered Truman. He later informed David Lilienthal, "I told him the blood was on my hands -- to let me worry about that." But over the years, Truman embellished the story. By one account, he replied, "Never mind, it'll all come out in the wash." In yet another version, he pulled his handkerchief from his breast pocket and offered it to Oppenheimer, saying, "Well, here, would you like to wipe your hands?" An awkward silence followed this exchange, and then Truman stood up to signal that the meeting was over. The two men shook hands, and Truman reportedly said, "Don't worry, we're going to work something out, and you're going to help us." Afterwards, the President was heard to mutter, "Blood on his hands, dammit, he hasn't half as much blood on his hands as I have. You just don't go around bellyaching about it." He later told [Secretary of State] Dean Acheson, "I don't want to see that son-of-a-bitch in this office ever again." Even in May 1946, the encounter still vivid in his mind, he wrote Acheson and described Oppenheimer as a "cry-baby scientist" who had come to "my office some five or six months ago and spent most of his time wringing his hands and telling me they had blood on them because of the discovery of atomic energy."

Barbie: extremely driven narrative with clarity and focus and streamlined design that always pushes the message the director wanted to give, while making room for fun and for serious at the same time, full of diverse cast and characters

Oppenheimer: literally none of that

#one also passes the Bechdel test and one does not #three guesses which and the first two don’t count #barbie #oppenheimer #like if you’re going to make a movie about the man who made the atomic bomb #you’d think you’d at least go into it with an opinion on that man? or on the bomb?
