Nuclear scientist here. Bravo on the explainer. I’m consistently impressed by the writing from you guys.
any relation to Bob Redwine?
@@DrDeuteron not that I know of. I’m 41 years old and never in my life have I met a person named “Redwine” who wasn’t a second cousin or closer relative. There aren’t many of us.
Hello, aeronautical engineer and armature nuclear scientist (meaning I just study the discipline as a hobby), I have to agree. I am impressed with the accuracy and effort put into the research and writing, despite being an abridged history of nuclear weapons. This very subject can easily be a longer multi part video. I am a little sad there wasn't a mention of Wernher von Braun being the engineer of our rocket program and his reluctance of rockets being used for missiles.
The symbol for radiation is a film projector reel. Radiation aside I'm calling splitting the atom movie magic considering all the old footage of bomb testing was movie studio produced

I truly love the long form simon whistler no matter the channel, I work nights so this is perfect
I hear that, some people's content is good enough that the Vids ain't long enough, Kinda like the Triumph song Lay It on the line, great song, one of my top 5's, and no where near long enough lol.
I drive long routes all day so this I perfect for me too
Yes, I work nights in manufacturing and these long form videos are great for that.
I’m grounds maintenance and the whistlerverse is my day. I’m all in on 3 hr content, shame RUclips would make it to hard to be worth the effort to get paid
As long as Simon's ok, we're all happy with the content.
Simon, blink twice if you're not ok.
Simon saying to stick around for a couple hours made me check the video to make sure he wasn’t toying with my emotions!
he sugarcoats what the Germans and Japanese were doing to receive a reaction from the US in order to create and use the bomb in the first place
it wasn't just "you do it first so they can't"
it was "they are genociding the planet, starting with Poland, Europe, and next you"
I don't know about everyone else but I love these long form videos. I'm a truck driver, and these are my background noise for the day. This one was especially interesting. It's crazy to me that there are those world leaders out there that have all this information and more, and yet they're still seemingly chomping at the bit to use them. If humans ever go extinct, I'm betting it will be our own fault, or rather their's
I used to listen to long stuff as a box truck driver, and traveling piano teacher
I consumed twenty six beers, a multipack of Wheat Crunchies, a large mixing bowl of popcorn, two small children and a pack of sausages watching this. That was a good watch to take up half of my night!
Ah yes, consumable children! 😂

I remember reading Tom Clancy's "The Sum of all Fears" in highschool, and that kind of roughly explained how nuclear bombs work, I'd recommend it, and a lot of other Tom Clancy books, they are great reads.
Agreed, Clancy goes into great detail of the events that occur between a timer saying "Let's explode!", to the bomb actually exploding, to what happens afterward, both compelling and scary reading.
For some comparisons to put things into context:
Little Boy's yield of 15kt is equivalent to a pile of TNT that's just a smidge under the weight of the German WW2 era Admiral Hipper class cruiser (most famously including Prinz Eugen, which ironically was used as a nuclear guinea pig at Bikini Atoll)
The first fusion weapon Ivy Mike's yield would need a pile of TNT 4 times heavier than the Great Pyramid of Giza
ANYTHING but the metric system
and add radiation
Nuclear weapons are also just over engineered fire bombs. If you're close enough for the shockwave to get you the intense heat would have already done its thing.
@@toastercatx 15kt is a touch north of 30,000,000lbs
@@toastercatx I'm British. We use both imperial and metric in a weird eldritch combination of sorts. The numbers were more to put the kiloton and megaton numbers into a better context

Simon's AI writing crew is compensating for inferior hardware.
Simon, my father worked on Project Hurricane, he told me that the reason why the UK went down the path of an independent nuclear deterrent was because we had the US with nuclear technology demonstrated, we knew that the soviets were working towards it. But we found ourselves in the middle. After the US slammed the door on us in 1946 by the US, after we had given them every thing we knew, we were piggy in the middle, we had no choice. This caused a massive reallocation of funds and we could not afford the old colonial system, not that I defending it. The simple fact is that in the late 40's and 50's London was the financial capital of the world and the worry was that if the Soviets sailed a boat with a nuclear device on board into the port of London they could have wiped out the world's banking industry and turned the clock back to the middle ages. Let us also consider the massive economic advantage of nuke missiles, you don't have to pay an air crew to over fly enemy territory to drop their cargo, or have to avoid flak from pissed off natives as you fly back after dropping it. Your videos are awesome but we do need to consider all the points of view
Excellent point, well made 😅 The Americans were not our friends during those years.
The American government isn't anyones friend, not even it's own people@@markkettlewell7441
This might be the single dumbest most misinformed point of view of all time. The us got all of their nuclear knowledge from the nazis whether it was from stolen intel, or scientists that either defected or they saved from Nuremberg. Britain hasn’t been anything since the 1800’s. Hence why their little brother had to save them in 2 separate world wars. 🤣🤣🤣🤣🤡🤡🤡🤡
Yes we were! We were just a little paranoid over all the little Oxbridge Communists handing over our nuclear secrets because of their "principles". We still loved you enough to bail you out financially.@@markkettlewell7441
Always the Yankees fault.
Technical aside from a guy who knows a thing or two about this…Uranium 236 is also incredibly stable…just look up its half-life. But the process of U-235 capturing a neutron results in U-236 with an unstable nucleus, because not all the protons/neutrons are in their ground energy state. This is called an excited atom, denoted like this: U-236*
And U-236* is incredibly unstable, unlike U-236, so it will almost immediately fission.
A small section of inter fission/fusion bombs are often overlooked, with two notable shots.
The first of the two "Item" shot was a boosted fission bomb where a small amount of tritium was burned in the plutonium core. This fusion itself provides a negligible amount of power, but the fast neutrons it releases allows a close to doubling of the plutonium that is fissioned before the core blows itself apart.
Item yielded 45 killotonnes.
The second was "George" shot which was a semi staged hydro test. This was a further refinement of boosting in which a significant portion of the power delivered was from fusion itself. Its practical scale however was limited by the incorporation of fusion fuel into the fission device itself. You could argue the soviet RDS6 is a version or variant of this design.
George had a yield of 225 killotonnes.
One thing I like about your many channels is that you give the informations you have found, usually very good information, but you also warn us not to be surprised if we find different information on a specific point . And it is very pleasant, respectful and informative towards your audience in order to preserve our critical spirit with regard to your comments. And that’s something that’s increasingly rare in today’s media. This is one of the things that makes me prefer your very informative videos to those of other channels. Continue to educate us intelligently 👍
Anyone who is interested in the Manhattan Project or the development of atomic weapons, I recommend "The Making of the Atomic Bomb" by Richard Rhodes. Just finished it and while it goes into depth (for a non-theoretical physicist) about nuclear physics, it seems to be the best single piece of first hand accounts of the birth of atomic physics ever written.
It’s available on audiobook. Especially great for LONG road trips as it’s about 30 hours long and goes into excruciating but very interesting detail.
Veritasium has a great video to explain that when nuclear energy was discovered, it was a purely atomic scale phenomenon that scientists had no reason to think could ever be harnessed for power generation let alone for a bomb. That changed when Leo Szilard envisioned a chain reaction.
I was just running out of nuclear documentaries. Thanks for filling my void.
The fact he dipped out of physics is the most tragic thing. He could of added as much as fermi or durack etc. Sad. The fact he felt guilt after being left in a zero choice scenario is depressing. He was a scientist, not the best, but damn he was the right man to corral that bunch of off the wall physicists. He should have been proud. The bomb was inevitable. Mr Anderson.
At least teller was vilified for the rest of his life for what he did
@@Shinzon23You mean getting Oppie’s security clearance pulled because Teller was jealous of Oppenheimer’s ability to manage the Manhattan Project?
@@o2benazTeller was skipped-over for running the Super project and Livermore Radiation Lab, which he was not happy about.
Atomic Weapons don't exist.It has been over 70 years now.70 years are a long time for a mortal.Given Human Nature if Atomic Weapons really existed;Someone would have used them to take over The World by now.Just stop and think for a moment.You have a Invention - The Atomic Bomb,which is capable of demolishing Entire Cities,which can crush The Human Spirit and which has "The Power" to literally enslave/conquer The Whole World and No One All Of This Time has tried to take over The World???It doesn't make any sense.Some people might say this is because of "Mutually Assured Destruction",but my devastating point is this:The Americans were "seemingly" the first to develop Atomic Weapons years before Anyone else,so if The Americans were the first to develop Atomic Weapons and had Atomic Weapons,then why didn't they use them to take over The World.They could have bombed every other Country in The World and then enslaved the survivors.No Army in The World could have stopped them at the time.People will say what about Hiroshima and Nagasaki?What about All the pictures,photos,videos,destroyed buildings and dead bodies?When I look at those pictures and videos of destroyed buildings;they look "burned","scorched" and "incinerated" to Me;not by "One Giant Brutal Super-Bomb",but by Thousands,Tens Of Thousands maybe even Hundreds Of Thousands of "Mini-Firebombs".To Me those devastated buildings don't appear to have been "Crushed" by "One-Single Mega-Brutal Crushing Super-Force",but by "Innumerable Smaller Burning-Forces".Hiroshima and Nagasaki look like burned Towns/Cities instead of Towns/Cities that were completely wiped out by "One Enormous Force".Now this is only Theoretical.I could be very-wrong,but if Atomic Weapons truly existed - by My estimates a Atomic Bomb would have not only "Completely Flattened" a Entire City to a pancake,but it would have also left "A Giant Crater" in the ground.The sheer "Monstrous Crushing Force" of a falling Atomic Bomb would have not only flattened The Entire City to ground-level it would have also "Torn-Apart The Very Ground From The Ground Itself".The Entire City would have been "Grinded Into Dust"- there would be Absolutely Nothing and Nobody left except "A Enormous Crater".There would be no clue that a City even existed.Example:If You build a Sandcastle on The Beach ( The Sandcastle is The City and You are The Atomic Bomb ) and then jump and stomp on it or punch it with All of Your might;it will Completely Flatten and You may even carve a Deep Hole in the ground.The Demons and The Fallen Angels who rule over this World need "Human Life Blood".Hiroshima and Nagasaki were "Satanic Human-Sacrifice Rituals".All of those Hundreds Of Thousands of people were being sacrificed to Demons and Fallen Angels for their blood.Many Ancient Civilizations from The Past were also sacrificing people for their blood,because The Demons and The Fallen Angels told them so.The Wars in The World are Human Sacrifice Rituals.Nothing has changed.Atomic Weapons are a monstrous deception designed to frighten The Public out of their Minds in order to create a Future situation where A False Saviour or False Saviours can rescue them.If Atomic Weapons truly existed;Someone would have used them to take over The World by now,but Nobody has and maybe this is because Atomic Weapons don't exist!
The reason Teller was the way he was, he experienced first hand what the Soviets did to Eastern Europe after the First World War. He experienced just how depraved they could be. That deeply affected him on a personal level. Because of that, he never trusted the Soviets to do the right thing. He was a much more deeply complex man than you give him credit for.
I was at the Trinity Site on it's 50th anniversary. I met a former Army MP that had been there on the day of the first atomic explosion. Truly, a "Bucket List" item for me.
*P.S. (1) If one Russian Officer had done the job, years ago, as he described he was trained for, We'd all be dead. He didn't trust the information that he was receiving from their missile detection system. Just because the Russian "Early Warning System" was unreliable and declared a false incoming missile attack of hundreds from the U.S. (2) A very high altitude EMP overhead attack using one nuclear weapon, would shut the U.S. almost completely down. Not a single mushroom cloud would be involved. These two statements are based on information that I have read and heard on documentaries.

The "silver plate" paint job wasn't rattle can or even paint at all. It was called silver plate because they didn't paint it to save weight. The silver was the color of the metal it was made of.
Interesting. I thought maybe the color was chosen to reflect thermal radiation from nearby nuclear fireballs.
By the time your brain registers the flash the reaction is already over.
Kind of like being in a failing submarine near the titanic.
I think the reaction is over before the flash, because the 1st ultra short flash is the completed explosion heating the bomb case, which becomes a millions of degrees light bulb filament for a brief period, then for a few milliseconds your seeing the heated air, and then finally it's expanding slow enough a shock wave can overtake it, and then you're looking at the compressed/heat air in the shock, which is much colder than the fireball behind, but still a few hundred thousand degrees (F, C, K, R, idc).
The closest we can imagine is a thousand lighting bolts, all stuck in the ON position.
@@DrDeuteron of course, when talking nuclear we would be remiss not to mention that simultaneity doesn’t really exist anyway. 😂

The first measurement in weight of plutonium was done at the University of Chicago Jones laboratory. The small room is on the national register of historic places, and labeled as such on the door to the room. And of course, the first self-sustaining nuclear pile was done at Amos Alonzo Stagg football field on the campus of the University of Chicago, in a squash court underneath the seating area.
Crickey, a 2 hour video, I've saved this for my Friday night favorite.
33:30 The biggest issue making a bomb is enritching enough U235, it took YEARS for the USA to get enough together for a couple of bombs, and it's the biggest stumbling block for all the countries who have tried, so the idea that a little shed in Wales was churning 51KG a day (enough for about 10 bombs) in 1943 is laughable.. Love the rest of the video though, only a couple of little mistakes.. Good watch..
Awesome content once again. I don’t want to be one of those jerkoffs in the comment section, but I don’t think that the crew on the Enola Gay looked down and thought “innocent civilians to be slaughtered”. They had to live with that the rest of their lives. The crew of the B-29 had never seen nor could they comprehend the power of the weapon that they were about to employ.
I have come soon enough. So soon that no one has watched the entirety of this video, 54 minutes after uploading.
I couldn't come soon enough.
I'm always coming...Squish
I believe the fissile material isn’t the only radioactive particles to spread… the closer to the ground the explosion is, the more dust and non-fissile material can be spread around, making ground bursts much more dangerous than air bursts in terms of residual radioactive materials.
What a great explanation of how nukes work in the first 11 minutes I've got some TNT and yellow cake in the kitchen also an Arduino for timing I think I might have a good old DIY try at a nuke this weekend 😜
Good video.
One thing I do want to note, is that in the “Nuclear Club” section (1h in), you forgot Israel, which gained nuclear weapons somewhere between France and China, alongside South Africa. Israel’s programme IS surrounded by secrecy, but they definitely have at least 40, if not more.
Fusion weapons is when fission weapons go Kaio-ken.
Kaio-what?
@@SuperVALERockKen...

This is why I love this channel. I learned to only use my nukes as a last resort. It also helps that H-bombs release much less radiation.
Huge confusion between irradiation and contamination (and further heavy metal poisoning)
Two hours on nuclear weapons and not one mention of Leo Szilard. Hmm. He pretty much started the Manhattan Project and all.
Man him going into the deep explanation of the effects of the nuclear bomb on Japan are chilling. It's hard to not see that as pure evil.
No,what japan was doing to others was inhuman...
@@jeffdroogExactly. The two A-bombs dropped on them were nothing compared to the decades long suffering, devastation, and death they brought to all of the countries they invaded and occupied up and down the pacific.
Japan in many innovative and disgustingly barbaric ways butchered (yes, like animals) an estimated 23 MILLION civillians and POWs. That does NOT include Allied military dead.
In turn, Japan suffered an estimated 3.5 million dead including military casualties.
They got off easy.
At the peak of the wider Manhattan project it was as a whole across its dispersed sites, estimated to be consuming 10% of the total electrical power generated in the USA as a nation. One can see that this scale effort was well beyond the reach of the UK alone.
It’s interesting to hear that the UK had already achieved such success in enriching Uranium. This is significant part of the problem and so a gun type bomb would have been a realistic proposition in short(ish) order.
1:31:01: The Soviets went as far as to copy the Boeing logo on the Tu-4's rudder pedals.
I have visited Hiroshima earlier this year. The peace memorial museum is beyond impressive. I have no words to describe the horrors on display there.

- [ ] Thank you Simon for your thorough and engagingly presented history of nuclear weapon development. I would like to offer a tiny, almost massless correction. At about 43:30 you mention that at the point of maximum pit compression, the initiator releases a burst of neutrinos to trigger the chain reaction. While the complex cascade of reactions that occurs during a nuclear explosion does release neutrinos, the chain reaction is initiated by the release (or injection) of neutrons. Neutrinos are useful for detecting nuclear testing, even for sub-kiloton devices, because neutrinos only extremely rarely interact with ordinary matter. This means that a test deep under a mountain can be detected on the other side of the globe almost as easily as if the test were performed a few miles away. This minor issue should not in any way detract from your superb production.
Unintentionally including my Costco list is the Universe’s way of rebuking me for making such a petty comment.
Thank you for mentioning the South African program. Its amazing how rare its even given a single tiny footnote and how people know about it or the voluntary ending
Or the even rarer known about Swedish bomb project.
Simon...love ur vids....but Einstein except a letter to Roosevelt had nothing to do with the gadget...it was Fermi and Salard....
Tsar Bomba was only one quarter the blast of Krakatoa, capable of going up to half of that volcano. the mind boggles to the point of apathy 😳😐
The tone at the end reminded me of a quote "Cave-men of the world, unite!" from Mordecai Roshwald's 'Level 7' circa. 1959, a story written as the journal of a "button pusher" in the lowest level of an unspecified super power's deepest nuclear bunker.
The most bleak and depressing story I've come across, do NOT recommend, but the quote is amusing. It is a portion of a "slogan" that the last 2 surviving bunkers exchanged as a game. Since nobody left alive even knew why they were fighting they had signed a peace treaty, and were referred to as "the ex-enemy".
Epic efforts 🤯Thx
I deeply resent the description of how US war planners viewed Hiroshima without at least balancing it against the MASSIVE amount of horror and suffering the Japanese had unleashed on the world, or the other driving factors for use of the bomb… namely an exhaustion for throwing away the lives of tens of thousands US soldiers fighting a defeated enemy who’s last objective was to take as many Americans with them as possible. Yes, civilians paid the price for the choices of their leaders but we can never know how much further horror was avoided by bringing Japan to surrender and avoiding a mainland invasion of Japan which still would have killed hundreds of thousands of civilians. Not excusing the use of the bomb, but that was a wildly one-sided take on the choice to deploy it.
Not using the bomb:
1) a million Allied deaths and ten million Japanese deaths in Operation Downfall.
2) a hundred thousand deaths per Month in Japanese occupied areas (mostly China)
The U.S. should have used More than 2. Only the Nazi's and the Jews get all the Press. Japan and their heinous crimes are virtually left out of History. My father fought in Europe & Afrika, U.S. Army, my father-in-law fought in the Pacific Theater, U.S. Army and An Uncle was U.S. Navy Pacific Theater. Japan was EQUALLY Evil As the Nazi's, in Every Way. Japan Brought This On Themselves!
Japan didn't have The Vatican to help them escape to South America at the end of WWII, like the Nazi's did.
There are good books on this subject that would dispute your comment.
Hiroshima was the choice target for a number of reasons, namely the geography meant that the explosion and fireball would be better reflected and do greater damage.
It had also been spared conventional bombing, and this made it easy to do though assessment of the damage that a nuclear blast had achieved.
The invasion of the Japanese mainland had already been cancelled, and not simply because the bombs were ready.
There was also a number of options considered for the use of the nuclear bombs on Japan that were considered and and dismissed. This included dropping a bomb on an unpopulated area as a demonstration of the power.
They also considered warning the city that was to be attacked to allow a large amount of people to evacuate. This was also dismissed. An attack on an unsuspecting, untouched population was the choice.
@@jimmyfreemantle879 Any book that disputes his comments can hardly be called "good".
Hiroshima was a target because of it's military use, its factories, and because it makes no sense to bomb a city that's already been bombed out.
The invasion of the mainland, Operation Downfall, was Not cancelled. The planning was just about done in the first week of August, with a November start date.
Dropping one of the few bombs in existence on an unpopulated area was deemed to be throwing away our only chance to shock the Japanese into surrendering. There is a ridiculous amount of evidence behind this.
Same reasoning for your "warning to evacuate". It robs you of the only chance to shock your enemy.
You need to change the fairy tale books your reading.

As a long time viewer, I appreciate the longforms. Much love!
Best summary of nuclear weapons ever. Thank you so much to all the team putting this episode together.
I recently watched a documentary on Netflix, Hitler and the Nazis, it mentions Pearl Harbour but doesn’t say a word about Hiroshima and Nagasaki. Well done Simon for putting such emphasis on the subject as am sure there are younger viewers who were probably uninformed about it.
Well that would make sense, you were watching a documentary on Hitler and the Nazis, not Tojo and Japan, or World War 2 as a whole, so it wouldn’t make any sense to mention the bombing of Hiroshima and Nagasaki.
“Everything you need to know about nuclear weapons…but were afraid to ask.”
Question. Let's say ww3 starts and nuclear missiles start flying all over the globe. Is it possible for bombs to crash into each other?
I was born in 1970 and grew up with the constant knowledge of the 4 minutes warning. I remember being 10 years old and schoolyard conversation being "what would we do if we got the warning there and then. Let me repeat We were Ten Year Olds
Helluva breakdown
I love these videos all the different channels I listen to them at work.
The reason why the Neutron Flux Indicator wasn't called a detonator is because technically not a detonator. It wasntwo specific elements one in the beginning of periodic table and the second I. The middle. Also there are more than U and Pu elements which are a blessing to sustain and multi generation create sustained fission reaction.
At 55:00, when the video says "[The gun type] Mark 1 was obsolete the moment the Trinity test was conducted", that's an over-simplification, given that the US continued gun-type warhead development into the mid to late 1950's, in parallel with the development of megaton scale thermonuclear warheads, and we didn't retire the last gun-type warheads until 1992.
It's true that gun-type warheads are fundamentally less efficient than implosion warheads, but gun-type warheads have (or had) the advantage of being physically rugged enough to be used in ground-penetrating applications where the warhead needs to survive 300,000 G's of impact force (this was the uprated requirement created in 1950 for forward-looking gun-type warhead development). In particular, the Navy funded the immediate post-war development on gun-type warheads in order to have earth-penetrating bombs for attacking submarine pens, warheads that could survive being shot out of a battleship gun, and warheads that could survive high-velocity water-impact to create a subsurface blast.
Mark 8 was a gun-type gravity bomb. In 1956, it was replaced by the Mark 11 gun-type gravity bomb, which was in service until 1960.
The W9 was an 11 inch artillery shell with a gun-type warhead (literally, a gun being fired out of another gun!), replaced in 1955 by the W19, which was in service until 1963. The battleship variant of the W19 was designated W23, and was in service from 1956 to 1962.
The longest serving gun-type warhead was the W33, an 8-inch artillery shell that was a "double gun type", meaning that both halves were fired and met in the middle, reducing the required barrel weight. In service from 1955 all the way through 1992.
The gun-type artillery shells had much higher 5 to 15 kT yields compared to the equivalent diameter implosion-based W79 artillery shell's 1.1 kT, or there was a smaller 155mm W48 shell with 0.1 kT of yield. Implosion-based artillery shells required the development of two-point linear implosion, which wasn't available when the earlier gun-type shells were developed.
Something worth correcting about nuclear artillery: Both the US and the USSR maintained nuclear artillery stockpiles all the way up to the end of the cold war. They were just able to downsize their nuclear shells to be fired out of standard field artillery guns, so they didn't need dedicated nuclear cannons. See, for example, the W48 155mm nuclear artillery shell, which could be fired from any standard US 155mm gun. It remained in service until 1992. The Soviets (and later Russia) also had nuclear artillery shells that could be fired from any of their field artillery guns into the 1990s. Nuclear artillery definitely didn't go out of style in the early 1970s.
Brilliant stuff as always, Thanks team MegaProjects.
