The Virtual Scotsman well a quick google search tells me... nothing, but I think it’s something to do with Fat man and little boy (Hiroshima and Nagasaki)
If you go to Scott Manleys channel he has a playlist "going nuclear" that goes into great depth looking at the development of nuclear bombs. Might be something you'd be interested in.
Japan could have done that too but they decided to invade China. Seems less likely they'd have had the manpower or economy necessary to win that race. Don't forget that even in 1938-1944, the US had a massive GDP lead on everyone else. About 6 times the GDP of Japan at the time.
Yeah Japan was fighting against huge odds, they couldnt sustain a long war so they did a huge bet on pearl harbor. The idea was to cripple the US and then do a "blitzkrieg", their generals knew that if they failed there the war was more or less lost.
I love the fact that Frisch and Peierls were't trust worthy enough to work on something as mundane as Radar but had a free pass to help with the atomic project which potentially could of had much larger repercussions had they been spies.

Otto Frisch (see correction below), Richard Frisch not Otto Frisch was the nephew of his famous aunt who during a vacation together in the backwoods with snow falling created the equations necessary for fission. He and his famous aunt concluded that the way to split the nucleus was not to shoot a neutron into the nucleus at a high speed, but rather send the neutron in as slowly as possible so that the already heavy ladened nucleus was already "wobbling" with too many neutrons. By sending an extra neutron in very slowly it might be "grabbed" by the nuclear strong force and "added" to the already overstuffed nucleus. That one extra neutron was enough to make the already unstable overstuffed uranium atom able to burst like a wobbling water balloon and explode. This is what fission really was. It's not shooting a fast bullet like extra neutron at a hard to hit the target but rather sending in a very slow neutron into very heavy uranium atom already with "overstuffed" neutrons spraying out radiation so that one extra neutron would cause the "water balloon to burst. Thus the chain reaction would begin. Question: If a water pond has Lilly pads growing on it and every day the Lilly pads double in amount and on the 90th day the pond is full on what day is the pond 1/2 full? Answer: on the 89th day. That is how fission works. So who was Otto Frisch's (correction, Richard Frisch's) famous aunt who was the real genius? Answer: Lisa Meitner.
I must make a correction to the above and admit I was wrong with my history. Today I re-read (listened to my audiobook on E=MC2 by David Bodanis). The true nephew of Lisa Meitner was Richard Frisch, not Otto Frisch. I confused Meitner's nephew with Otto Hahn, Lisa Meitner's university collaborator. Additionally, I recalled after reading the book that it was not Lisa Meitner who first discovered that water could slow down the neutron before it would attach to the nucleus. That prize must go the Enrico Fermi, who discovered that water from his fishpond outside his underfunded first laboratory would slow down the neutron. But Fermi never understood the math behind the science. It was only after 3 or 4 years later, in the cold winter woods in Europe with her nephew, "Richard Frisch" would Lisa Meitner calculate the equations to establish why slowing down neutrons would allow neutrons to be "captured" by the tiny nucleus inside the Uranium atom.

Another fantastically researched and presented mini-documentary by the Curious Droid. Somewhat embarrassingly, I kept thinking about what if "nothing happened" (00:20). Never return to a lit firework.....
It has happened. In one of the U.S. tests on the Nevada test range, one test shot was set up and counted down to zero. Nothing happened.

The German flag was accurate. That was Germany's flag between WW1 and the WW2. In fact the Japanese flag is not accurate, that's the flag of the Japanese military, not of the country itself.

Another amazing episode! I had no idea that atomic weapons were being researched in so many States. This channel is one of my favorite and I am thrilled when I get a new notification. Brilliant. ✌🇺🇸🇬🇧
Something worth noting is some of the scientists were not sure that if a bomb was detonated that the nuclear reaction would simply continue until the entire planet was consumed.
@15:38 I have noticed trails of smoke present before some of the bomb tests. Did they launch rockets with smoke trails right before a test detonation to visualize the shock wave?
What's the background music at 8:30? I think it's provided by TH-cam but shazam just links to copyright stealer's songs (changing a free use song slightly and trying to monetise it).
Love this channel. Not enough posts, but considering the obvious amount of research and sheer bloody work you must put in, understandable. Keep 'em coming.
One point worth mentioning that wasn't touched on was the chemical advantages of Plutonium 239 over Uranium 235. Uranium 235 was very hard to extract from mass of 238 because they are chemically identical, so some subtle, long winded techniques had to be used. Plutonium on the other hand could be extracted by relatively simple chemical processes.
Sir Marcus Laurence Elwin "Mark" Oliphant AC KBE FRS FAA FTSE (8 October 1901 - 14 July 2000) was an Australian physicist and humanitarian who played an important role in the first experimental demonstration of nuclear fusion and in the development of nuclear weapons.
In 1941, science fiction writer Robert Heinlein published "Solution Unsatisfactory", a short story in which he predicted that nuclear weapons would lead to a world in which war would be "all offense and no defense".
They didn't do it fearing it could happen. They did the math very seriously and found the ignition point of our atmosphere. As such they knew that the test would be safe, but obviously take precautions because math and reality can misalign
Awesome video Paul! I would really love to see, and I believe your viewers might be interested in, you doing a video on the British nuclear program after the war, Operation Grapple, as well as the 24 British nuclear devices set off on U.S. soil at the Nevada Test Site up through the 1990’s!!!
@@halimceria The invention of Nuclear weapons has all but removed the possibility of a world war, if one were to occur there would be no-one left afterwards.
Most roots stemmed from the industrial revolution, however times of war calls for arms race which drastically increases research and productivity to one over the opposition.
This is a very complete, thorough and accurate history about the development of early atomic weapons. Very impressive, per the usual for Curious Droid.

You could do a follow up video on the contention between the US and UK regarding nuclear technology following the war. The US government decided not to share nuclear weapons info with the UK, even though many of the scientists on the Manhattan Project were Brits (and even though the USSR already knew everything). The UK's lax security checks had allowed several Soviet spies to slip through the cracks, which was part of the issue, bet there was a lot of geopolitics going on after the war. This led the UK to eventually develop its own nuclear weapons, and the rush to do so indirectly led to the Windscale nuclear accident.
A few corrections and omissions. H.G Wells came up with the Chain reaction, Szilard only did the math to prove it worked, after reading about in an H. G. Wells book. You failed to mention the letter from Einstein to Roosevelt.at Leo Szilard Behest that accelerated US Nuclear research. Hiroshima was the 2nd atomic Bomb, the first was the Gadget detonated in Los Alamos, The Hiroshima Bomb used both US and German Uranium. The German Uranium was Captured when the submarine carrying the Uranium to Japan decided to Surrender to the US when Germany Surrendered.

This is my favorite Curious Droid video so far. Thank you for your commitment in producing these videos. I always look forward to the next one!
these videos obviously take a lot of time and research to produce so I hope people watching appreciate the effort it takes to make them.
Something worth noting is some of the scientists were not sure that if a bomb was detonated that the nuclear reaction would simply continue until the entire planet was consumed.
Didnt they also think that it would ignite the atmosphere aswell ?
@@ProjectUnsoundDineen That was another consideration also.
Fantastic compilation of clips, videos, and information narrated brilliantly by Sir Paul Shillito 😉
@15:38 I have noticed trails of smoke present before some of the bomb tests. Did they launch rockets with smoke trails right before a test detonation to visualize the shock wave?
Brilliant well-researched interesting videos. Keep up the fab work!!👍🏻
What's the background music at 8:30? I think it's provided by TH-cam but shazam just links to copyright stealer's songs (changing a free use song slightly and trying to monetise it).
Been waiting so long for my CD fix! Thanks Paul!
Shirt looks amazing!!!
Love this channel. Not enough posts, but considering the obvious amount of research and sheer bloody work you must put in, understandable. Keep 'em coming.
Felt like ages since you uploaded.... welcome back :)
Leo Szilard. Also would recommend a book by Groves himself for those interested in the engineering production and delivery aspects.
I misread this as "How The Atomic Race War Was Won" and was very concerned

One point worth mentioning that wasn't touched on was the chemical advantages of Plutonium 239 over Uranium 235. Uranium 235 was very hard to extract from mass of 238 because they are chemically identical, so some subtle, long winded techniques had to be used. Plutonium on the other hand could be extracted by relatively simple chemical processes.
Leo Szilard is "sillard", not "slizzard". great video as always though.
Actually it's a hard Z at the front.
So, zeelard ;)
So amazing packed with so much information I had to watch it twice. Thank you Curious Droid.
Yay! Now that's the way to start off Memorial weekend!!! Good Timing CD!
What's the name of the background instrumental starting at 10:29 ?
I actually have a sample of heavy water from Norsk Hydro :)
What? Lol
What does it taste like ? Do you have enough to make some tea ?
Just found your channel and I'm finding your videos on the nuclear subject very informative and entertaining. Very easy guy to listen to
Man, glad to see the Lord of Light brought you back after Dany had you torched...
LOL I wondered where I saw him :)
Ha. I am glad as well. I wonder if the Lord of Light brought him back whole or missing a piece.
They used IBM tabulators and mechanical calculators on the Manhattan Project. And also some of the early computers.
Yes, Feynman writes about it I think
thank you sir and as always ...nice shirt
I’ve returned to all of your videos several times. Great work, keep them coming.
As always excellent quality of the video and research. Thank you!
Sir Marcus Laurence Elwin "Mark" Oliphant AC KBE FRS FAA FTSE (8 October 1901 - 14 July 2000) was an Australian physicist and humanitarian who played an important role in the first experimental demonstration of nuclear fusion and in the development of nuclear weapons.
(1:06) - Mancherter University?
I know it well.
Phahahagag
Man, what is the name of the song that starts playing at 10:30 in?
LX-24's Bullshit “from russia huma huma “
I loved you on Game of Thrones!
Too bad about the flaming ending.
Me too
In 1941, science fiction writer Robert Heinlein published "Solution Unsatisfactory", a short story in which he predicted that nuclear weapons would lead to a world in which war would be "all offense and no defense".
"So there's a chance that we'll destroy the atmosphere?
-Yeah.
I'm willing to take that chance."
I don't believe there was ever a chance, but fear brings worst case scenarios into people's minds.
"Many of you will probably die horribly. It is a sacrifice I am willing to make."
And as lucky as we were, we have fucked up the earths ecosystem with these tests
It doesnt matter what actually happened. It was what feared could happen. Yet they still did it
They didn't do it fearing it could happen. They did the math very seriously and found the ignition point of our atmosphere. As such they knew that the test would be safe, but obviously take precautions because math and reality can misalign
Awesome video Paul! I would really love to see, and I believe your viewers might be interested in, you doing a video on the British nuclear program after the war, Operation Grapple, as well as the 24 British nuclear devices set off on U.S. soil at the Nevada Test Site up through the 1990’s!!!
Ahhh. Gotta get my nuclear fix from Curious Droid. It's a good day~
Excellent work Paul...great research and my favourite subject....enjoyed event minute of your film.
God I love mid century technology. Almost all our tech today has it's roots in WWII or the post war prosperous 1950s.
This was a great video as usual.
true. we need another world war to push the technology to whole new level.
@@halimceria The invention of Nuclear weapons has all but removed the possibility of a world war, if one were to occur there would be no-one left afterwards.
Most roots stemmed from the industrial revolution, however times of war calls for arms race which drastically increases research and productivity to one over the opposition.
The biotech and telecommunications tools we use now are only vaguely related to 50’s technology.
Still flying pretty much the same airplanes, though.
At 15:50 did anyone else see two faces in that atomic mushroom cloud?
This is a very complete, thorough and accurate history about the development of early atomic weapons. Very impressive, per the usual for Curious Droid.
would you like to share a music title at around 7th minute of the movie?
You should set up a Patreon account. I would gladly support your channel every month!
He has one. If you pay me all of the donation money, I will be glad to pass it on to him. That applies to everyone else too. Please make checks payable to 'Mr C. Tapper' with a note, saying 'for the benefit of Curious Droid'.
He does excellent work, so make very generous donations please. He deserves thousands of bucks. Many, many, thousands. I would suggest at least $500,000 would be appropriate. Thank you. And hurry, my new Porsche needs paying for soon. I mean Paul's new one. Sorry.
can u please do a video about the sky bolt and blue steel missiles or the weapons on the v bombers or maybe even the different Vulcan variants?
Good stuff. But I feel you failed to mention how bad the US behaved towards the UK when it came to sharing knowledge.
As usual Paul, the attention to detail here is remarkable. Keep em coming mate 👍
This is the droid I was looking for.
You could do a follow up video on the contention between the US and UK regarding nuclear technology following the war. The US government decided not to share nuclear weapons info with the UK, even though many of the scientists on the Manhattan Project were Brits (and even though the USSR already knew everything). The UK's lax security checks had allowed several Soviet spies to slip through the cracks, which was part of the issue, bet there was a lot of geopolitics going on after the war. This led the UK to eventually develop its own nuclear weapons, and the rush to do so indirectly led to the Windscale nuclear accident.
Brilliant video as always
Also answers a question I began to think about the other day
Do you have a Pateron? by any chance i would love to support your channel in any ways i can. Seeing how you always bring QUALITY over Quantity
Curious Droid video day, it’s a good day 👍🏻
A few corrections and omissions.
H.G Wells came up with the Chain reaction, Szilard only did the math to prove it worked, after reading about in an H. G. Wells book. You failed to mention the letter from Einstein to Roosevelt.at Leo Szilard Behest that accelerated US Nuclear research.
Hiroshima was the 2nd atomic Bomb, the first was the Gadget detonated in Los Alamos,
The Hiroshima Bomb used both US and German Uranium. The German Uranium was Captured when the submarine carrying the Uranium to Japan decided to Surrender to the US when Germany Surrendered.
first report about necessary creation of atomic bomb L.P.Beria put on Stalins table at january 1940..
Small human glitches or not you’re productions are amazing given your practical limitations. I’ve enjoyed your channel over the last few years I hope there’s many more. One of the best on TH-cam by far sir.
