- The science and engineering of the atomic weapons is interesting. In this video, I tried to explain working of the 'FAT MAN', The second atomic weapon exploded over NAGASAKI, JAPAN. First we will go through the basic science of nuclear fission and then we will explore all other important components of the bomb. finally, some visuals of the day of bombing. I hope you will find it interesting and informative. if so, please do subscribe and like the video, also, don't forget to mention your views in the comment section.
The animation is made in Blender 3.1 (EEVEE)

This is the "engineering of Atomic Bomb explained"...for the rest of us.
I never thought such a complex engineering mechanism can be explained so simply any eloquently.
Well done!
I am a nuclear physicist and this is a very well done BASIC explanation. It is very accurate, but understand the complexity is significantly greater than this video. If you get anything from this, i hope everyone now understands that a nuclear detonation from a dropped bomb or air crash is impossible because of the incredible precision of the explosives to compress the sphere.

@@aduboi1534agreed. It’s just most of these videos assume the viewers are stupid and leave out stuff like the explosive lens. If you have advice for a more detailed look, I’d love to take a look.
Just starting American Prometheus now.
@@aduboi1534also, THANK YOU I always wondered why that live nuke the American govt accidentally dropped on American soil didn’t explode. I was on tour with a punk band and our host brought us to this little tiny sign that commemorates the event. I couldn’t conceive why this wasn’t more commonly held knowledge.
sir pakistan is building also
Amazing. I NEVER understood until now that the symbol for radioactivity is actually a depiction of the explosive lense charges with the supercritical mass at the center. Mind blown.
It is not, it represents activity radiating from an atom.
Quote: _The three-bladed radiation warning symbol, as we currently know it, was "doodled" out at the University of California Radiation Laboratory in Berkeley sometime in 1946 by a small group of people. This event was described in a letter written in 1952 by Nels Garden, head of the Health Chemistry Group at the Radiation Laboratory: "A number of people in the group took an interest in suggesting different motifs, and the one arousing the most interest was a design which was supposed to represent activity radiating from an atom."_
I cannot imagine the USA, in 1946 on an ultra top secret project, designing a warning symbol which gives the architecture on how to do an atomic bomb, it would be like:
_"Hey every one on Earth, this is how we made it"_ ;)
@@patlab555 that’s interesting. truth is always stranger than fiction, here it is because somehow the doodle still ended up looking exactly like an explosive lense and a supercritical core. Crazy.

Give this man a medal, i havent seen a nuclear bomb presentation so detailed and well made. The animations were awesome and you explained every step with detail and you also started the video with the basic idea. You should be more popular 👍👍
You too
Fr. I’m tired of seeing all these lazy slideshows with AI voices.
This was how I learnt it perfectly in chemistry and physics till some TH-cam guys tryna confuse me into doubling mass that becomes unstable and I wonder how that represents the well understood physics and chemistry that I was a distinction student in.
The only thing is I wasn't told back in school that you have to let the distance between atoms in the plutonium be very short to increase contact possibilities.
I taught there will be continuous contact however.
I agreed 100%
I think the lack of content is the defining factor here... he's only made 13 videos.
Whats also insane is how the animation is pieced up together to form a well made video! This channel deserves more subs!
If he makes more videos (he's only made 13), I've no doubt he'll increase his subs.
True
Best explanation,Oppenheimer is proud of you bro
I read somewhere that Oppenheimer had to go to Jon von Neumann for the explosive lenses solution 😊
If anyone is starting this and wondering if it’s accurate and worth the time, yes. It is. Best description that for a layperson, lays out the basic details most of these kind of videos leave out. The explosive lens is such a beautiful, complex engineering idea. Thank you for making this.
Worse than the carnage and devastation caused by the bomb it also makes Zirconia atoms which are used for fake diamonds

Congratulations, man! You did a great job in the rendering!
@@Droolbaby agreed....it sounds like a indian try to speak english....good video tho!
@@Droolbaby 😡🤬
The video animation was done well. Facts were lacking. The weapon killed between 60 and 80,000 people. Not including the late effect radiation

Microsoft call centre, what can i help you ?
This is the very best explanation that ive seen on this subject. I feel like i have a thorough understanding of how it works, and an immense appreciation for the engineering involved
It was wonderful documentary. With all the superb explaining and detailed illustration, my mind still can't fully wrap around how something so small can become so big and powerful in the blink of an eye. It's like trying to understand gravity, invisible forces. Bugs me a little bit.
Ive never seen an explanation video at this much clear and precised. Thankyou
This is the best explanation EVER of how the bomb actually works
Best explanation of the actual engineering I've seen on TH-cam, and the way he says "Thirty-two detonators" fills me with an inexplicable joy.
This is absolutely the best explanation of the workings of the bomb that I've ever seen. It's difficult (at best) to give simple explanations and still capture this much detail.
Very well done!
Will you make one ?
@@pauldjdundas No. Neither bomb nor animated video are within my means or skillset.
LOL
Such an incredible achievement… but also horrible and terrifying. With great power comes great responsibility
Great power with great responsibilities.
Human against the other remaining nature. Human himself destroying own home
Definitely radioactivity is inside the earth since beginning. Most dangerous type of energy. Number of incident occurred Chernobyl, Fukushima known to us, we unable control it. We have numerous atomic arsenals if not destroyed properly may destroy mother earth absolutely
Not if that great power was handed to a woman.
Ppl don’t care about the well being of themselves and others….why would anyone be stupid enough to make those?

@@montedyoung3247 Mutually assured destruction in order to incentivize peace between big world powers.
This is so well explained. I'm just from watching an Oppenheimer video by Veritasium, then I read about the Japanese vs US war so I got curious about the bomb. I may have to watch it again and read further to cement my understanding but you've made it an approachable subject without prior knowledge, thank you.
Same
This is the best video I've ever seen on an Atom Bomb... please make another on Hydrogen/Tsar Bomb.
My uncle was in the Marines and went to Nagasaki weeks or months after the bomb. He’s been in many war zones, conflicts, Korea, Vietnam, etc. but said he had never seen such destruction before and that he felt bad for the people of Japan. Even though they started the war. His sympathy was great for them.
There in lies the moral dilemma. Was the use of this horrific weapon on an unsuspected civilian population justified ? Your uncle witnessed the aftermath, did it change his opinion om nuclear weapons?
Do not get me wrong I am not particularly a pacifist, but I do consider nuclear weapons an immoral obscenity and would have been better never to have been created at all!
Both Nagasaki and Hiroshima were mainly buildings made of wood they were literally firebombed into submission similar to Dresden not one person that I know in military has ever witnessed a so called nuke being exploded they use it as a scare tactic
@@khankrum1 The problem lies in the Primary Mover. Japan tried to take an inch when they bombed Pearl Harbor and killed innocents along with military, America came back and took a mile for what they did to us.
Imperial Japan slapped a lion in the face and thought the entire pride was asleep. They got what they deserved.
Let's face it. Imperial Japan slapped a colonial cockroach in the face and the cockroach did what cockroaches do.
Instead of manning up to the situation, they dragged it down to a pathetic tit for tat like 5 year old moronic pre school sandbox children.
@@khankrum1 You hit the nail on the head. This obscene weapon was used on a civilian population, NOT a military target. By any objective reasoning this is a crime of the highest order. The USA to its disgrace is the only country to have used a nuclear weapon. I have also heard that Japan was on the verge of surrender at the time and that the nuclear bombs were unnecessary making their use even more obscene. Chalk up another mega war crime to the USA.
Never quite understood the mechanics of the explosives' action that was created to make the sphere reach super critical mass to create the fission reaction itself, which is measured in picoseconds. An incredible feat of science and engineering.
We do know

Pls make another animation for Fusion bomb. 👍🏻
Would you please tell me how you do the videos? They’re so realistic and and clear. I intend to make a similar channel but for anesthesiologis, graduated ones. Id appreciate the sharing…
Lets talk in detail. Mail me on the mentioned I'd in the description! themindnetwork2020@gmail.com
@@Curism 🙏
Very very well done Sir! Incredible to see a simplified explanation of the most complex and destructive device ever build. Please continue your great work! 👌
This video is awesome. Good job man, thanks for all the detailed explanation and animation.
After seeing this video, I now finally understand the reason why the hazard symbol for radiation looks the way it looks.
Excellent, clear explanation of a complex subject. Thanks for the effort taken to keep the graphics and detail accurate and understandable while not ignoring the moral dimensions.
One of the best animations I’ve seen on this. They even got the witting initiator design and explosive lensing detonation waves correct - which people usually gloss over. Excellent!
The enormity of the engineering required to make the first atomic bomb is mind boggling! Thanks for making this video to help explain how it was done.
Thanks a lot. It's the best explanation for a frenchie: Slow and clear diction. Very serious and motivative.

Cool video!! I have published extensively on the physics and history of the Manhattan project, and I would show this to my students. A few very minor quibbles: It is more properly called an "implosion" lens (for obvious reasons), the Po and Be have to be separated initially (I think they used gold foil to stop the alphas until the two were mixed by the implosion), the Pu core was in two hemispheres (they had to put the initiator inside!), and the bomb was raised into the plane form a loading pit in the ground. But these really are quibbles. Love the 3D deconstruction of the bomb.
Right, having gold between the beryllium and polonium would explain why the neutron burst from the initiator comes after the implosion. Until now I assumed the initiator was always emitting neutrons but that they didn't have an effect until the plutonium was supercritical.
This has to be the best explanation for a layman I've ever seen and I've studied this at length. Brilliant video. Beyond the horror that is the bomb, the engineering is stunningly complex. To think that the Manhattan project had to think this all through in theory before testing is a testament to the genius of the scientists.
I have sen many videos explaining the atomic bomb but must say this one is by far the best one and explaining/showing it in a really "easy" way that not to complicating to understand! Awesome done by the creator!
Man this was a tremendously excellent visual representation. Bravo. Thank you
I’m 5 minutes in and the fact that someone was able to figure this all out is absolutely mind blowing 🤯
Literally
Outstanding rendering of the composition of Fatman! Well done! I had tried to piece together in my mind the structure of the bomb from written descriptions and drawings, but this really helped clear things up.
Some commenters are grousing about the (Indian?) accent, but I find it very melodious and easy on the ear. I occasionally have to listen twice to a word because of emphasis on different syllables than I am used to, but that’s not really a problem. I have conversed with English speakers from a number of countries and regions, and to my American mid-western ear the Indian accent is one of the most pleasant. More so than some of my countrymen!
A small nit: the depiction of the B-29 Bockscar, that carried Fatman, is a bit off. The atomic bomb-carrying B-29s were modified and built to a different configuration under the codename Silverplate than the standard conventional bomb-carrying B-29 depicted in the video. The most obvious differences with respect to the video are that Silverplate bombers had no gun turrets to save weight for payload, and the engines and props were different (although very similar). Not obvious were that armor was also removed, and fuel tanks installed in the fuselage. And the bombays were reconfigured to carry either Fatman or Little Boy.
Also, the Fatman was too big to simply roll (especially by a single man!) under the aircraft as depicted in the video, the scale of bomb to plane is not quite correct. The bomb on its cradle was lowered into a pit, the B-29 was positioned over the pit, and the bomb was hoisted into the bombay.
But that is not central to the focus of the video, so no worries.
Again, well done!
Thank you!!
Fantastic video with the best animation and graphics I have ever seen on the subject. I am obsessed with nuclear physics so have seen hundreds of videos and lectures. Your teaching skills are excellent. It takes a lot of work to simplify this subject. Congratulations to all of you who worked on this.
Great! Me 2, I'm already doing my masters in nuclear engineering
Let's become friends, we can share some information, what are you studying? :)
@@Pau182pau I'm not studying. I work in logistics. I just love the subject since the age of 12. Nuclear weapons are my primary obsession. Radiotherapy and the biological effects of ionizing radiation is my second favourite area. I dont think I could tell you anything you don’t already know ..!
Further to my last reply, I am only self taught in this subject so can offer little but I think you could help me understand some things if you don't mind discussing.. Here is my first rather basic question -
If you had 2 atoms of freshly made Plutonium 239 in a box, that after 24,000 years one of those would have decayed and the other would have not ? How long after the first would the second atom decay ?
And what controls this ? Is it due to subatomic or weird quantum processes ?
Also on the topic of fusion ..As you know Hydrogen bombs use a fission assembly to initiate fusion, but now that we can trigger fusion in the lab setting without detonating a Plutonium weapon first, do you think it is possible that we will see pure fusion weapons in the near future? And do you think Californium weapons will ever become viable ? It would be a nightmare if battlefield artillery weapons started using Californium in my honest opinion.
Look up nuke lies.
.. everyone who contributes to making nuclear weapons is a murderer. They are not good people.
wow this is an incredibly detailed and insightful video. the graphical renderings were top notch and professional. thank you. great work
Outstanding video. Clear, accurate, no frills and no cheap moral last words.
The best explanation of atomic bomb I have seen so far...
Amazing. What I want to know is how in the hell did people figure out these invisible and complex elements and how to manipulate them to yield such a catastrophic result. It blows my mind how people figured this stuff out.
Quantum physics
Agree . All those great minds but somewhere along the line they seem to forget that they are building something to kill their fellow man . Seems strange to think about .
Big respect putting this video together. Intricate and complex concepts made crystal clear and fascinating. So insightful, thank you
Till this point, this video has been the most coherent representation of the implosion-based atomic weapon, regarding every single aspect. Excellent digital rendering and usage of allegories (such as comparing the instability to jenga) makes the representation even better. Jolly good!
Quick fact, a name 'Jenga' comes from a Swahili word meaning 'Build'... It's a wonderful thing to have this significance in the world...
@@nazirkatabaro6347 I wasn't aware of that fact. Glad to know, thank you for this interesting piece of information.
Mind blowing video..🙏 I think the best video on Fatman in the world..
I watched many videos but couldn't able to understand but this video is very clear and simple, a common man can easily understand the concept... thanks a lot...
I used to work on A-4 Skyhawks which at one time had been nuclear capable. As an electronics technician I wondered at some of the remaining electronics and came away with the thought that a nuclear bomb must need a lot of electrical current to detonate. Now I know that to be true and why it is needed. Great video.
yes but 5kv really wasnt that much. 7mm high tension wire would suffice from say spark plug leads. Heck, automotive points-type ignitions provided that at the time. CD ignitions produce about 40kv at high speed!
What is your evidence that nukes exist?
The best explanation I have seen on the subject. Thanks for a great job! I can recommend the book "The Making of the Atomic Bomb", by Richard Rhodes.
Yes. Thats great book. And the author wrote another book on Hydrogen bomb also.
And read this if you want to not sleep well for a few days. Confessions of a Nuclear War planner by Daniel Ellsberg.
A very good read.
An amazing book written when many of the scientists and engineers and military personel who worked on it were still available to be interviewed which Rhodes did. One notable interviewee was Bethe. Another was Teller. A book where one should read the notes at the end and the bibliography.
@@animalntelligence3170 I am not assuming anything here, but if by chance you aren't aware of a fascinating bit of history, Google "The Atomic Bomb and Kodak." Essentially, Kodak was developing standard run-of-the-mill course photographs when they discovered the finals were spotted, which they could only conclude was due to stray atomic particles/radiation. This was well over 1000- miles away from Los Alamos.
Kodak basically discovered that experiments with radiation were going on at a grand scale, in an era where secrecy was at it's highest.
Seriously, Google it. In the mean time, best regards and have a great weekend.
I've seen a few videos on this subject, and I have to be honest, this was by far the best most detailed explanation and presentation that I've come across thus far. Excellent video my friend 👍🏼
Thank you for the extremely interest video. The content and graphics are awesome.
I’m blown away.. this is THE BEST VIDEO explanation of how it worked with great animation..I’ve been looking for a video like this for years.. and finally it’s here..THANK YOU THANK YOU THANK YOU..now I finally have a clue as to how it worked..
An incredibly well made video. Very well put together, one of the best explanations I've seen.The 3D work is damn good.
wow, even as a 14 year old I understood everything in this video, completely clear, fantastic! the visuals were very helpful, too. I saw other videos on bombs and this one is easily the best. great job! 🎉
Great job explaining the details. My initial question is, how did they experiment with all this material without killing themselves? Did they do all this via calculations and then hoped that it would work in the first desert test? Did they do very small tests to determine the types, ratio and shape of the explosive material needed to trigger the compression? I find the process of how all these details became known to the scientists to be fascinating.
Many scientists and researchers died from radiation exposure. Look up Marie Curie and also look up the Demon Core accidents.
I have the same question, along with who initially started pursuing this with what goal in mind? I’m hoping the new movie “Oppenheimer” answers all of these questions.
I have seen maybe a hundred different videos or documentaries throughout my life that gives you pieces of this, but nobody has ever explained it and put it all together. Congratulations on this video!
Fantastic video. Very clearly explained with every detail. Amzaing at the same time most scariest engineering inventions of all time.
Keep making more videos.
This video Came into my feed right before watching Oppenheimer 🎉
I just watched this for the third time. I'm so impressed with the way that you presented this and the information and the graphics are simple but represent quite clearly what is going on inside
I am a student of the nuclear weapons game, and this video is the most accurate I have seen. It's excellent in all respects.
The absolute best explanation and animation of the Fat Man "Gadget" !!!! Great Job!!!!!
Simple, clear, concise. Well done.
Lets hope there's no end game to this example?
What an amazing explanation of the atomic bomb, even someone like me, with no scientific awareness could understand this ,
Brilliant presentation.

As an engineer ..this was the best explanation i had in my chemistry lectures.
just in awe at the almost unbelievably massive engineering challenges to get this contraption to actually work in the 1940's. truly an incredible story.
Unlimited budget and no enemy bombing of the facilities during testing and manufacturing helped the US come up with just enough enriched material for 3 weapons.
it didn't work so they firebombed instead.
@@DrCorvid what didn't work?
@@ct1762 they don't have nukes; the nuclear experiment didn't work so Nagasakli and Hiroshima were firebombedi, with intact wooden buildings and other combustibles remaining at ground zero. Marshall Islands were dynamited, both sides, and the posters all doctored but you know that one... Depleted Uranium burns fast and leaves traces but it's not what they were trying for.
@@DrCorvid what you're saying couldn't possibly be true. The Earth would have to be round for that to be possible.
I've never seen it explained in this detail, excellent job.
Considerably more complicated than simply a plutonium ball surrounded by TNT. Those dead guys were really smart---without computers to do their thinking.
I just heard the narrator, and I am overjoyed. His voice is unique and completely different from every other narrator from this platform.
This is the most explanatory video on atomic bomb with such a good animation and exact facts and the specific science behind each step. Most of the videos I have seen miss to explain 2 points, the detonation wave and the fact the whole detonation process finishes within millionth of a second. Unimaginable speed. Nuclear physics is beyond the realm of our day to day physics. And these are the same electrons, protons and neutrons behaving so differently in different atmospheric conditions and atomic arrangements.
wow, this is pure excellence. clear, precise but most importantly understandable. thank-you.
Who is here after watching Oppenheimer 💥💣
Making the bomb 💣 isn't that hard but making weapons grade plutonium or uranium is extremely hard.
Not only making the material but infact getting enuf material is most hard thing itself.
Who's watching this after Oppenheimer
YOU have done a REALLY GOOD JOB of explaining the ENTIRE event! Especially the TECH side!
This is by far the best and most detailed video that I have seen on this topic and easy to understand too. Thank you so much

The best description and video of the plutonium bomb process that I have ever seen! It was very easy to understand, even for a lowly non-physicist like myself.
I have a question about thar plastic shell, how it absorbs the slow moving neutrons and avoids pre detonation. The part that create the neurons is at the center of polonium so before the shell can absorbs that slow neutrons they create a chain reaction.
Do neutrinos have to have a certain speed for a chain reaction to take place? And if they are slow, they can pass through the polonium cavity and chain reaction will not occur.
What software did you use for the animations and models
Beautifully explained through visuals!
Very thoughtful interpretation of science, especially in its narration too.
That was incredibly presented, the concept simplified, yet it retained the necessary details! kudos!
Superb. Many thanks.
nearly correct :)
it is uranium that explodes first (after the normal explosive) and that explosion then compresses the plutonium and creates no. 2 explosion.
without the uranium bomb it doesn't work, as it is the one that creates the pressure needed to make the plutonium explode
Best video I've seen on the workings of the device. The exploded (pun yeah) views of the lens layers is awesome too.
How on earth could anyone possibly conceive of something so abstract and impossibly complex, let alone actually engineer and construct it? If I didn’t know this all to be true, I would have never believed any of would be possible.
I was just thinking the same. But I suppose back in the 30s and 40s people had a far far greater knowledge and expertise in a subject. Less distractions, better sleep, more time etc. Today we are bombarded by distractions. Same applies to huge human achievements like Notra Dame, the Pyramids etc.
@@GudieveNing Maybe we’re just getting dumber overall? I wouldn’t be surprised. Cheers.
By far the best explanation of the inner workings of a nuke I have ever watched (and I used to be an AF tech. on ICBM's).

Thank you sir for the education. Very clearly explained and illustrated. Just a clarification, is it critical mass or critical density? Seems like the mass is not changed by the compression, correct?
