How it Works Fat Man Oppenheimer Trinity Atomic Bomb
Вставка
- Опубліковано 19 вер 2024
- 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.

Can you show us a step by step tutorial how to build one please .
😂😂😂 lol
😅
Please make video on this
Iran wants to know your location
😂😂
Clean visuals + very simplified commentary makes a big difference in understanding for us non-academic folks.
🙏 Your Awesome we tried our best.
To think that this was 80 years ago, and we still have people that think the world is flat to this day. Great explanation, thank you!
Your Awesome too 👍 thanks 🙏
Its not hard
@@vishveshtadsare3160 ah yeah I'm sure you and your grandmother can build one out of the scrap in your backyard yah
... and this now a very crude design. We marvel over miniaturization in our electronics, but nukes did it first!
@@vishveshtadsare3160 The engineering is hard. Getting the focused explosives into the right shape, the thicknesses of the layers around the core, and the fuse timing takes a bit of calculation.
This was done very well from a scientific perspective! As a retired member of the USAF with hundreds of hours of aircrew time I love it.
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.
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!
Happy to watch your videos 👍 thanks for your information
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. 🤷
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.
Unbelievable what these men accomplished . No computers to calculate what then took months to do today those calculations would be done in hours. Total respect.
"hours"? Do you have a steam-powered computer?
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?
They did have computers. But your point is not without merit.
@@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...)?

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.
Incredible video. The amount of effort you put into this is amazing
One of the most detailed video about nuxlear weapon!🙏🙏
Thanks 👍
These animations (Blender's not that easy to master), and the work you guys put in, AND of course the concise explanations as to what and how it happened is otherworldly! Love your channel and these videos; keep them coming! 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.
It’s amazing they had the technology to make the three different radioactive parts of the device in perfect nested spheres
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.
@@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.
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.
Dear Mr. AiTelly
You gave a very nice explanation with 3D visuals…
It is mind-boggling to see the depiction of this type of weapons operating on the earth's surface in a habitable place.... It is the desire of the people of the world to use this science only for creation...
My thanks to you for making it clear to those who don't know
its crazy how Oppenheimer gets all the credit
Nah the movie describes what he did very well.
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.
@@krymsun3134Nope. Oppenheimer's most important contribution was reorganizing the project, and the movie didn't say one damned thing about it.
@@perniciouspete4986 what are you talking about he spent an hour organizing it lmao
I always like your vids mate... the 2 people behind the animations are top-notch. Always recommend this channel to a fellow UA-cam watcher out there. Great stuff.
Your awesome mate 👍
Thanks 👍
J'adore regarder plusieurs de vos vidéos d'une traite, même si après je fini par avoir de maux de tête car je dois les voir en sous-titré. Vous faites un travail magnifique.
This is an outstanding explanation of this subject. You guys are incredibly good.
Great as always. Nicely done.
So freaking awesome (the animation that is)!
Very good presentation; easy to follow and understand. Keep em coming!! o7
Wit Do
Amazing video thanks. The thing I would have liked to have seen explained is why the design of the plutonium bomb changed so radically from that of the uranium bomb, but I understand the constraints you face in making this kind of video. More please!
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.
What a beautiful animation. Well done.
this is so massive i had to watch it like 5x to understand it for some reason.
It is valuable to note that this plutonium bomb was totally unneeded in order to drop Abombs on Hiroshima and Nagaski; U235 gun bombs had already been made and needed no testing. The use of the Plutonium bomb was to confirm plutonium rather than U235 could work; it likely would have worked in a gun type bomb but the U239 was contaminated with U240. The value of the use of Plutonium was that as it was a different element from U238 it could be extracted more easily than U235. All later Abomb development was around U239 not U235 because of the relative ease of extraction; never the less a country must have U235 first in order to make a reactor.
Outstanding work as always keep it up 👍🏻
Incredibel animation and easy to understand explanation. Love it!
It is interesting to read about the people involved. All were fascinating people, who were human with the usual human foibles. The story of General Groves who was essential in trying to coordinate everything and tame the personalities of the scientists and technicians that built these bombs. An excellent video that explained the construction of the bombs and how they worked…which is not found in other descriptions of these weapons. Well done.
Considering this was made in the analog era, all these (failsafe) sensors working together is the hallmark of UNFATHOMABLE COMPLEX engineering. I am IMPRESSED!
Yes agreed 👍
Really nice video guys...
An idea for next one: The tsar bomb?
Love the video! Gotta do the H-bomb next
Great channel for my little brother who always ask questions on how things work. He love your channel AiTelly ❤️❤️ keep it up.
Glad your Brother liked it 😁
Your Awesome
Outstanding work as always keep it up . Incredible video. The amount of effort you put into this is amazing.
Amazing and incredible work.
I appreciate your videos immensely. Amazing quality, content is always interesting, just beautifully delivered information It's always a nice surprise to be notified of a new video.
Thanks Nicola Pare we love you guys 🙏
Imagine dropping the bomb but you forgot to pull off the 3 arming plugs 💀
The plugs were automatically pulled out when the bomb dropped. They were connected to the plane inside the bomb bay by wires. As the bomb dropped out of the plane when the plugs reached the end of the wires connecting them to the plane, they were pulled out fully arming the bomb. The green plugs separated the arming circuits from the explosives. When the red plugs were put in that gave continuity to the explosives and tests could be run to verify circuit operation. When the red plugs were pulled out, the arming circuits were fully armed in the bomb.
The details presented in this video will remain incomprehensible to anyone who does not already understand the physics involved.
One without knowledge in physics clearly doesn’t need to know how to build an atomic bomb, if they cared enough they’d acquire at least a bachelor in physics
I met Commander Frederick Ashworth at a presentation in Los Alamos in 2005.
Had an interesting conversation with him after the presentation. He was 93 years old and passed away a few months later.
He armed the Nagasaki bomb( Fat Man).
Very nicely done! I wonder if there is an overview somewhere of all the work - metallurgy, chemists, physicists, others, who contributed to the creation of the device?
keep doing great work guys 👍
Thanks You👍
Your Awesome
So, the bomb is a football ball 🤣🤣
Had the worst dream last night, North America was thrashed by plutonium and uranium spheres like this with nickel spheres closed around them, one detonated right above me and my brother and the only thing between us and the blast was a couple feet of water. The blue flash was wild, I never wanna see that again.
Awesome animation explaining the complex concepts. Great work!
the plug was switched, not removed
Implosion is the most elegant solution IMO, I loved the Manhattan Project show that explores the development of the method. 🙂
1:24 why are 5 arming plugs there? I heard that initially all green plugs were inserted which isolated the batteries, then an operator switched all greens to reds connecting the batteries to the circuit. Good stuff guys. Sorry for being a pain in the ass, but after all I'm a research and development engineering manager. Keep up the good work!
Yes, a research and development engineering manager, so you can't help being a pain in the ass. You're forgiven.
excellent animation. one tip. slow down. take your time between steps, constructs. let the view had time to adjust and understand. ie make the video 10 minutes long
Ok understood 🙏👍
Editor deserves a salute
Cool, thanks sir Oppenheimer.
God bless.
Just watched Oppenheimer, great film. I do wish they had explained the science of the bomb a little more and the politics a little less :)
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.
Very good as usual
WOW ! WOW ! WOW !
SHOW ! SHOW ! SHOW !
That's what we have to call a fancy grade A+ 3D video !
Fantastic !
It's been years I have been waiting for a precise, concise and clear explanation of the nuclear bombs !
You guys are simply the best !
Keep up the excellent work and may God bless you always !
Thanks !
Thank You So much. We love you guys
Damn 24 volts and destruction beyond imagination … kinda silly when you think about like that… another great animation and video; I always wanted a play by play synopsis of what’s happening during this destructive process… question were there any cameras that actually were fast enough to catch each phase of the detonation ?
amazing sir
Great presentation!
Thanks 👍 Your Great Too
I thought they removed green plugs and placed in red ones? Or did they just pull three two red on green as shown?
10/10 step by step tutorial
Do one on the castle bravo fusion weapon, and the subsequent salted bomb variants
great how to! mine's almost complete
Please make an video about explaining radars
• how it works
•why old radars are curved and why new radars are flat
•how do they find a target how it will know it's range ,the direction it's moving
•what are the difference between x-band radars, L-band radars and vhf-band radars and how vhf-band radars can deduct stealth fighters and why x-band radars can't
Literally how it's works please🙏🙏🙏 make it happen please🙏🙏
The problem is UA-cam algorithm
We do not get Views when we make Videos that are not Trending 😔
@@Aitelly oh! Thanks or reading my comment I hope you will one day
Not an expert on radar, but I think the old curved radar has a centralized antenna, so it need a curved dish to reflect the signal to the target direction. The flat panel are phased arry radar, they have many small T/R units that can control its signal direction to a certain degree without physically rotating. Those units can either spread out the signal to cover a large area for search, or combine its power and focusing on a single target to get precise tracking for weapon guidance. The mechanical radar can also perform the same tasks by constantly rotating for search mode, or gimbal lock at the direction of the target for tracking. The biggest advantage for the phased arry radar is, they can switch between the those two modes at very rapid speed, because they dont need to physically rotates. This allows them to have much higher performance in a mode called Track while scan(TWS), which means the radar tracks mutiple known targets, while maintain the ability to detect new targets, which is great for situational awareness on the battlefield.
Unfortunately you have to find somebody else that likes making videos out of love and passion not just quantity of videos for profit
@@thecloneguyz no ai telly is a great you tube channel i love this channel because it's the only channel that reads my comment and replies to it
Unfortunately we need money to make these type of content
I think that was missing a step in the fast-slow explosives to create a "symmetrical" shockwave.
Ahhhh.. the magic of Blender 3D. Cool!
Great video really detailed.
Thanks 👍
Common knowledge to us now, but imagine sending this video back in time to 1941.
My cousin, Dr Donald MacRae, worked at Oak Ridge, Tennessee. He was a Canadian astrophysicist and worked with a small team of physicists on the purification of Uranium 238 for the Trinity bomb. There were a few Canadians involved throughout the Manhattan Project, he was one of them.
Thank you for this on how it all comes together!
Nice break down and explanation
Excellent video
Great work 👍
Excellent video. Thank You ! 🌞
Thank you so much for this animation!
Thank you for saying “NUMBER” before each number, I would have been confused otherwise thinking they were letters.
Oppenheimer was awarded the men's butts discount when he traveled to England.
Well done!
I wish they explained more of how the bomb was built in the movie.
Mind boggling how this was developed!! Harnessing the power of stars in the universe - wow!
Fusion is the power of stars, not fission. Think H-bomb versus A-bomb.
Ok thanks I'll try this out in my shed. You'll hear about it if it works
You show uranium undergoing fission in your final animation sequence but this is a plutonium bomb.
It's sorta crazy how simple the construction seems of so much death.
Yes
Only thing missing was the bgm
NOW I HAVE BECOME DEATH THE DESTROYER OF WORLDS
GREAT! work dudes
Keep rocking 🤘
Last two videos is very Nice
Thanks 👍
You n yr team creativity and dedication to producing high-quality content are truly commendable. It's evident that you put your heart and soul into each video, and that passion shines through in every frame.
Your videos have not only entertained me but have also broadened my perspective on different subjects. Your thoughtful approach to complex issues has encouraged me to think critically and explore new ideas. God bless
God bless you too my friend 🙏
We love you Guys.
Material the size of your morning grapefruit demolishes a city.
Good job i know how hard thisust be to animate this stuff i live your stuff
Amazing video. I wish they had taken some time to explain the inner workings of the bomb in the film. It would've been helpful to better understand it.
They would have lost 90% of the audience, which has the attention span of butterflies.
Fantastic video. Pronounciation: John Von Neumann (Noy-Mahn). Not "pallet." It should be "pellet."
There’s a few things wrong with this video. For example, Seth came up with the idea. The British dude was the one who came up with the shape charge idea to improve upon the initial concept as up to that point they couldn’t get it to work.
A video on how large aircraft carriers float and work please 🥺
Thank you, I walked away feeling I almost understood this.
It is fookin awesome..
Great one mate 👍
My friend: ‘it’s just a prank’! The prank:
And to think almost none of this was covered in Oppenheimer, which was 3 hours long by the way.
Good Job.
great video
Another great animation from AiTelly! However, your introductory credits on the development of implosion technology neglect the man most credited with bringing this new science to fruition: George Kistiakowski. He was the man in charge of "X Division" at Los Alamos which was responsible for development of the explosive lens. He apparently was a very hands-on physicist/chemist who was known to work on blocks of RDX explosives in he held in his lap. Not sure how you missed him, but look up his name in Wikipedia and you'll see how important he was to the success of Trinity and Fat Man.
So was James Tuck who suggested the two-part shaped charges (explosive lenses) with fast and slow explosives that Kistiakowski then worked on. The entire project was a collaboration among a lot of very smart people and not singular events by one person alone. Robert Serber proposed implosion in the "Los Alamos Primer" which everyone coming to work at Los Alamos had to review. Serber's first lecture was in March 1943, long before Kistiakowski worked on the Project.
The early days at Los Alamos would have been an amazing time to be part of for any scientist or engineer. So many bright minds working collaboratively on one goal and having an almost unlimited budget at their disposal. It all happened a few years before I was born, but I love reading about all the different people and the many ideas they each brought to the table. Thankfully this era of Los Alamos is well documented and makes for much good reading today. I got to visit Los Alamos in 1982 and give a talk about interactive computer graphics. I still vividly remember flying into an airstrip on the top of a nearby plateau in a de Havilland Twin Otter and then getting escorted around like I was royalty. Sadly no pictures of the trip though (cameras not allowed).
Cool Animation
thanks for this video and explanation!
~300k Subscribers only, WOW.
Yes
Concise and informative!
Thanks 👍
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.
Why were Little Boy and Fat Man so different? Were they designed and built by separate teams who did not know what the other group was doing? If there had been a third bomb, what form would it have had?
I read somewhere that for Fat Boy They Modified a Plane because it was too heavy ? It was strapped on the outside of the Plane
