How it Works Fat Man Oppenheimer Trinity Atomic Bomb

Oppenheimer Trinity Test, marked the inception of the implosion-design plutonium, eventually leading to the detonation of the Fat Man atomic weapon, over Nagasaki.
The outer charge explodes inward, followed by the inner ring of explosives, creating a concave shockwave.
It moves to the Aluminum pusher, breaking the barren plastic sphere.
The shockwaves continue toward the uranium-two three eight, It travels further compressing the plutonium sphere and compressing it more.
Interestingly this was James Tuck idea.
A British physicist who suggested employing shaped charges as three-dimensional explosive lenses.
But it was further developed and perfected by Von Neumann, a Hungarian-American mathematician, physicist and computer scientist.

Subbed for your amazing work that you guys put in ♥ And yes, I will consult my friendly neighbourhood nuclear physicist too for more; he may or may not be building a bomb to show me how it happens in situ

Still curious if they use AI for the voice narration with some of the weird pronunciations.

[@HistoryfortheAges]

I am a history professor. Saw Oppenheimer and loved it! I am no expert on the science behind all this, so this was a cool video. Thank you! The History of the movie was pretty spot on, but if you wondered how much of the little stories within the movie were true I made a new video on my channel answering many of those questions. Happy to share. Every historical movie embellishes some things, but overall it was a very accurate movie and amazing to watch!

[@Aitelly]

Happy to watch your videos 👍 thanks for your information

[@ghost307]

One science item that I noticed was Oppenheimer giving General Groves his estimate of 3 kilotons for the Trinity test. Oppenheimer actually thought that it wouldn't work being their very first attempt.

Speaking of history, The fact that the "Christian" West would commit and practice a great many cardinal sins, many of them knowingly, such as centuries-long global; - 'Colonization', - 'Genocide', - 'Slavery', - 'Colonialism', - 'Global Warming', etc which benefits them enormously for centuries worldwide; then they would initiate and take a measure to ban those practices worldwide, and take credit for it. [Note: Today's global warming is caused in large part by nearly two centuries of excessive coal burning, mainly in the West.] Christian European Colonization of, - North America & South America, - Siberia & Far-East Asia, - Australia & New Zealand in Asia-Pacific. 😔 Europe for Native Europeans, Africa for Native Africans, America for Native Americans, Asia-Pacific for Native Asians-Pacific islanders. 🤷

[@buckhorncortez]

The explosive lenses had two different explosives. The outer explosive was Composition B (fast explosive) and then the inner explosive Baratol (slow explosive). Composition B is a mixture of RDX (cyclotiimethylenetrirutiamine) and TNT (trinitrotoluene). Composition B consists of RDX (59.5 %, by mass), TNT (39.5 %) and desensitizing wax (1%). This explosive has a density of 1.70 g/cm3, and a detonation velocity of 8480 m/s. Baratol is a mixture of barium nitrate and TNT. It is 76% barium nitrate and 24% TNT. It has a density of 2.64 grams/cm3 and a detonation velocity of 4900 m/s. The final inner layer of explosives next to the pusher was made of Composition B.

[@GeoffreyFeldmanMA]

Seconds, not hours. I wish people would not comment with their unique feelings and personal speculations. Nobody cares if such as you have "total respect". What does "total respect" mean anyway? So - why post?

[@dontgetmadgetwise4271]

They did have computers. But your point is not without merit.

[@luceatlux7087]

​@@GeoffreyFeldmanMA While I understand and identify with your feelings, your approach is probably one that would tend to spread a bit of a negative, overcritical regard for our fellow human beings. 23 people identified with and purportedly enjoyed the sentiment to which you refer. Thus the more appropriate question might be: Why let such a benign expression elicit such disrespect ('No one cares if such as you...)? ---------------------------------------------------------------------------------------------------- further reading if you're a reader. if it's some kind of buirden, forget it. "ain't know won gunna reed all that!" ------------------------------------------------------------------------------------------- Just fwiw, I've ultimately come to the conclusion that, with the goal of prioritizing disdain properly and homing in on/understanding those who are TRULY making life worse (and curbing their influence vs helping the better influences), it's best to forgive the smaller things that have basically kindly intentions behind them (eg, this op would likely mostly be an expression to simply connect with others about a harmless emotion of being in awe; a positive regard of another). There is SO much ego-driven, incredibly-ill-considered, narrow judgment out there that's PURPOSEFULLY DESIGNED to belittle and spread negativity. So I always try and just silently forgive and forget irritations when people are just being people (sometimes absent-minded, irritating etc). If I work through it and understand that the intentions are essentially benevolent, I kinda' see it as a case of not being one of the 'patient zeros' for transmitting the true irritants in life. Not to mention, when you have the idiots who love the emotional tone of the intelligent harsher-spirited criticisms, they try to emulate this kind of thing (in an effort to exalt their immature egos) and it comes out as invalid criticisms of everyone they disagree with because they aren't smart enough to deliver valid perspectives or content with their emotional expression... smearing vehement ignorance all over the place. I guess I try to identify the intention behind stuff and try to understand what kind of regard it spreads (how des it affect idiots... smart people? average people? youths/immature people? etc)... or not; whatever. I try to save my emotionally-based criticisms (as yours is) for the REAL F'Kers who make things suck in life. sht... loooong.... oh well. take it, leave it. just thought i'd share some ideas about the issue.

It’s amazing they had the technology to make the three different radioactive parts of the device in perfect nested spheres

[@jakistam1000]

The fact that they are radioactive didn't matter much; they were just metals. As long as you don't exceed the critical mass, you can melt it, hit it with hammers, cut it etc., and it isn't any more dangerous than just standing next to it.

[@piotrd.4850]

@@jakistam1000 well actually, both uranium and plutionium are heavy metals, thus are toxic - and plutoium is particularly vicious. It sheds, is easily to oxidize, is cancerogenic as faq, produces bubbles of hydrogen inside.

[@dontgetmadgetwise4271]

Plutonium 239 is much more responsive to stray neutrons. The gun approach would have failed to bring the two components together before the energy released busted the assembly apart. A fizzle.

At 2:14 'the main fusion material' should be 'the main fission material'. Like Uranium, plutonium was used for nuclear fission, not fusion. Fusion was only used in the later and more potent thermonuclear bombs.

Someone has to take credit when they're able to move from theory to practice, if the original theorist isn't able to do it.

[@perniciouspete4986]

​@@krymsun3134Nope. Oppenheimer's most important contribution was reorganizing the project, and the movie didn't say one damned thing about it.

[@krymsun3134]

@@perniciouspete4986 what are you talking about he spent an hour organizing it lmao

[@lorentzinvariant7348]

Thank you for properly demonstrating the way the neutron causes fission. So many descriptions out there imply the neutron blows apart the nucleus kinetically as it randomly spits and releases neutrons. This is not the case. The neutron gets close enough to be absorbed by the nuclear force that acts at very small distances only. Upon absorption the nucleus becomes unstable and blows apart into specific fragments predefined by the internal dynamics involved also releasing additional neutrons in the process. There is a finite time between neutron absorption and fission.

[@chadtopia]

Great video with a very accurate explanation. I'm not sure the high explosives were actually comprised of two layers, rather, the slow HX fitted inside the fast HX at the bottom of the lens, but that's a minor detail. Also, Jon Von Neumann is pronounced Noyman but again, a minor quibble in an otherwise excellent video.

The movie was based on the book, "American Prometheus." That book deals with Oppenheimer and his life and not the science of the Project. That's why the science was tangential to the story of Oppenheimer in the movie.
