    The name dropping in Oppenheimer is intense. I recognised a load of them from studying maths and the characters were deriding maths for not being physics. Crazy that they could have such contributions to a field they didn’t even respect

      I just saw the movie last night and felt the exact same way. I said the first 45 minutes were basically just eye candy for nerds lol. Going through all the famed scientists of that era whom we grew up revering.

      Maths isn’t science but just a tool used in proper science…

      A disputable opinion but one that was widespread back then (see: no Nobel Prize for mathematics for example…)

      Haven’t seen the film yet so maybe I’m misunderstanding what you’re saying comparing physics to math in that way is like comparing apples to the molecules that make up apples. Physics is applied mathematics used to attempt to explain the physical workings of the universe. You can’t have physics with no math.

      And this is coming from an engineer, who thinks we’re superior to both!

      That’s one of the risks of kicking off a war.

      Close to the end of the war, Japan – which had made pretty extensive use of biological weapons against China – was working on also hitting the US with biological weapons. We were far enough away that it would have been difficult, but where they had been able to employ biologicals, in Asia, they did.

      https://en.wikipedia.org/wiki/Operation_PX

      Operation PX, also known as Operation Cherry Blossoms at Night, was a planned Japanese military attack on civilians in the United States using biological weapons, devised during World War II. The proposal was for Imperial Japanese Navy submarines to launch seaplanes that would deliver weaponized bubonic plague, developed by Unit 731 of the Imperial Japanese Army, to the West Coast of the United States.

      That being said, Japan wasn’t even the expected target of the Manhattan Project. Germany would have been, but was defeated via conventional force prior to the project reaching completion.

        I wonder why they didn’t drop the bombs in more remote locations first to minimize victims and send a message… Estimates are that 130k to 225k people died, the vast majority were civilians that had no influence over their country being at war…

          Because it would have been less-effective, I expect. The targets were chosen because they had military industry and had not yet been destroyed via conventional firebombing, which had already been done at mass scale in other places.

          I think that it’s important to understand that the atomic bombs were simply seen as something of a significant multiplier in the existing bombing campaign. One bomber with an atomic bomb could maybe do what a thousand bombers with conventional weapons might…but there were, in fact, thousand-bomber raids happening. That is, cities were already being set afire. The Manhattan Project simply permitted doing so with a significantly-lower resource expenditure.

          EDIT: Also, to be clear, the US fully intended to ramp up to mass production and employment of atomic bombs, dozens a month, once production could be brought up, and would have done so had the surrender not occurred.

          Today, partly because of (significantly more powerful) thermonuclear weapons and because we know that the first two bombs did result in a surrender, the first two atomic bombs maybe look like something of a clear bookend to the war, but that’s for us in 2023; in 1946, they would have been another step – if a significant one – of World War II’s large-scale bombing campaigns, something that had been growing for years.

          The atomic bombings were war crimes, but so were the many previous fire-bombings of Japanese and German cities. The US was doing everything it could at that point to end the war.

            Honestly, I’m of the opinion that the atomic bombings were legitimate, but the firebombings in Japan were mostly terror bombing and war crimes. The atomic bombs were indiscriminate in their destruction, but pointed towards legitimate military/infrastructure targets.

              That’s an odd take, the atomic bombings were fire bombings intended to destroy cities, unless you think the US didn’t realize that would happen? The US was quite capable of destroying individual facilities. Is it legitimate to destroy a facility and everyone who works there? And their homes? And their families, and their kid’s schools and everyone who goes to those schools and their doctors, and the guy who sells them snacks on the way home and his family and all his in laws and their houses and their doctors.

              Seems a bit excessive.

                The atomic bombings were not fire bombings. Fire bombings, as the name suggests, use incendiaries.

                You know what the accuracy was for daytime bombing in WW2, even with fancy American bomb sights?

                A mile.

                A. Mile.

                In Europe, British and American approaches differed because British bomber command put a greater emphasis on terror bombing against the Germans, while the American bomber command in Europe put a greater emphasis on industrial targets. You know what both approaches shared? Absolutely blanketing wide swathes of an area with ordnance because there was no guarantee of hitting a target otherwise.

                Given that low level of accuracy available, I don’t find arguments regarding collateral damage to be particularly compelling. No, what made US firebombing in Japan horrid was that American bomber command in Asia oriented quite explicitly towards attacking civilian targets. Incendiary testing in US trials was done against mock-ups of Japanese civilian housing, not industrial targets, even.

                Nagasaki and Hiroshima were chosen as targets because of their military and industrial importance. However cruel and indiscriminate an atomic bombing may be, it was not simply pointed at civilians in the hopes of murdering as many as possible, unlike the fire bombings.

                  This is historically ignorant. The cities were chosen for their psychological effect.

                  Atomic bombs are incendiaries. Starting fire miles away is one of the key effects of the bomb. They can create firestorms.

          You have limited supply of bombs, you go after targets. You don’t waste them.

          Hiroshima and Nagasaki were legitimate military targets.

            Came close to not being enough, even then.

            https://en.wikipedia.org/wiki/Ky%C5%ABj%C5%8D_incident

            The Kyūjō incident (宮城事件, Kyūjō Jiken) was an attempted military coup d’état in the Empire of Japan at the end of the Second World War. It happened on the night of 14–15 August 1945, just before the announcement of Japan’s surrender to the Allies. The coup was attempted by the Staff Office of the Ministry of War of Japan and many from the Imperial Guard to stop the move to surrender.

            The officers murdered Lieutenant General Takeshi Mori of the First Imperial Guards Division and attempted to counterfeit an order to the effect of permitting their occupation of the Tokyo Imperial Palace (Kyūjō). They attempted to place Emperor Hirohito under house arrest, using the 2nd Brigade Imperial Guard Infantry. They failed to persuade the Eastern District Army and the high command of the Imperial Japanese Army to move forward with the action. Due to their failure to convince the remaining army to oust the Imperial House of Japan, they performed ritual suicide. As a result, the communiqué of the intent for a Japanese surrender continued as planned.

            They tried to seize the recording of Emperor Hirohito’s surrender speech before it could go out:

            The rebels, led by Hatanaka, spent the next several hours fruitlessly searching for Imperial Household Minister Sōtarō Ishiwata [ja], Lord of the Privy Seal Kōichi Kido, and the recordings of the surrender speech. The two men were hiding in the “bank vault”, a large chamber underneath the Imperial Palace.[15][16] The search was made more difficult by a blackout in response to Allied bombings, and by the archaic organization and layout of the Imperial House Ministry. Many of the names of the rooms were unrecognizable to the rebels. The rebels did find the chamberlain Yoshihiro Tokugawa. Although Hatanaka threatened to disembowel him with a samurai sword, Tokugawa lied and told them he did not know where the recordings or men were.[12][17] During their search, the rebels cut nearly all of the telephone wires, severing communications between their prisoners on the palace grounds and the outside world.

            The morning the bomb was dropped on Nagasaki, another thing happened: Russia declared war on Japan, invaded, and had made huge progress in the night. There’s some evidence the guys at the meeting who decided on surrender had not heard of the Nagasaki bomb yet, though the bombs are the official reason Japan gives for surrender.

      We firebombed the rest of japan for years doing far more damage and yet you numpties only parrot the same whiny talking points. Be more creative.
