Damn I wish I could read

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.
Physicists treating their field as license to hand-wave other fields? Yeah, totally unrealistic.
- What other fields?

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!

Sadly, they are Thanos for people in Hiroshima and Nagasaki

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/OperationPX
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...
Now imagine how the japanese are seen by the people of China, Korea, Burma, Thailand, Malaysia, Laos, Cambodia, Vietnam, Sumatra, Singapore, Indonesia and Papua who were still living under japanese occupation and terror in August 1945. Who died in droves far greater than the Hiroshima or Nagasaki victims, with up to 25 million casualities. Whose death rates increased towards the end of the war, and for whom a delay of the capitulation of the japanese by a few weeks or, god forbid, months would have meant millions of deaths.
Who, mind you, did not support the japanese government, did not support the japanese war, had no way of stopping it except for fighting for their lives, yet still had to suffer from it. Unlike the people of Hiroshima and Nagasaki, who could have prevented the japanese government from taking power, who could have striked and fought against their militaristic government, who could have sabotaged the war efforts of their government in a war that was lost anyways - yet they never did.
- "Unlike the people" and their school-aged kids, and their babies, and the old grandmas. Don't let them off they hook, they could have taken down a military dictatorship that dominated East Asia if they felt like it.
- Like, there are still people alive today who wouldn't have been without the atomic bombs. And I'm not even talking about american soldiers here, I'm talking about civilians. Not dropping those bombs would have meant their death. Go on, tell them they should've died because the japanese civilians in Hiroshima and Nagasaki were innocently living their life and it totally wasn't their government, their labor and their devotion to the emperor that kept the war going.
  After all, the real victims of the japanese imperial war were the japanese. Totally! You know, those who until today have not accepted their crimes and instead openly deny it.
- I'm just worried that instead of ending second waorld war, we started a new one.
  looks into the camera
  A cold war.
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.
- I mean, I just took it as a 'snapping out of existence' joke rather than a political statement.

Unironically yes
