Wired you need to do a deep dive specifically on radiation. The four types, their particle physics identity, the shielding requirements, effects on a person, more information on how it’s spread (or not really spread), isotopes, decay and half-life, and finally dosage rates for background, common everyday sources (granite, bananas, and airplane flights) and nuclear dosage regulations and how strict the controls are.
There is much to much fear and misinformation around these that our normal education systems are not covering.

It wasn’t just the smoke and clouds that caused the switch to Nagasaki as they spent almost an hour above Kokura trying to sight the target (they had orders to only drop with visual targeting). They switched because anti-aircraft fire was getting close to hitting them and they had intercepted communications that fighters were inbound.

Mr. Wellerstein, I was with you until you described the protrusions on the side of the mock-up of an atomic bomb as ‘fuses’. I would appreciate an actual explanation – they don’t seem like pitot tubes like with a standard aircraft. How are they relevant to the determination of altitude?

I visited Hiroshima earlier this year, and I was surprised to learn that part of the motivation of using the A-bomb was to demonstrate nuclear capability to the USSR. Then post-war, the US didn’t want Japan to run into the arms of Communism, so they had the occupation and poured money in. But to prevent an uprising against US forces, they made it illegal to spread or even possess photographs of the destruction and injury at Hiroshima and Nagasaki. We only have about 100 photographs because some very brave people risked their lives to preserve them. It wasn’t until the occupation ended that the rest of Jaan saw the results of the nuclear weapons.

With that said I’m kinda curious now about what Germany’s take on the Hiroshima bombing was like. Yes they’d already surrendered by then and most of the higher ups were dead, but still! I’m sure some of them were still alive and were painfully aware of what had just happened, and who had accomplished it.

Project Sundial was not an attack weapon; Teller conceived it as a doomsday weapon. It would sit somewhere safe and out of sight, that would only be detonated if the US was attacked, with no hope of surviving.
Teller theorized that the Sundial device would effectively end all life on Earth, essentially being a preventive defensive weapon — if we die, we all die.

Minor nitpick, because I know it annoys basically everyone who lives to the East of where the Titanic sank – it’s ‘Ih-rahn’ not ‘eye-rann’ <3
Also, in the 'Lost nukes' section - kinda surprised he didn't mention how the US accidentally dropping unarmed nuclear bombs on Spain in 1966 nearly resulted in the Franco (fascist) regime reverse-engineering nuclear weapons.
And right at the end there - the Japanese surprisingly un-famously were actually a lot closer to 'atomic bomb' capability than the Germans - perhaps even as little as a year behind the US by some estimates.

I want to add to that first question: South Africa briefly had a nuclear arsenal but became the first country to denuclearize, beating the former Soviet republics to denuclearization by 1-2 years. They retain the capacity to develop nukes if necessary, as do Brazil, Canada, Germany, Iran*, Japan, South Korea, Taiwan, and The Netherlands (alphabetical order).
*Iran is a weird case because they might or might not be trying to make nukes. They have the capacity and the materials, but they haven’t put them together yet and say they have no intention of putting them together at this time.
ALSO, the reason food in fallout shelters is made to last forever is because it’s easier to stock the fallout shelter once and not worry about it than it is to constantly worry about “Is this food expired? Is this food safe to eat? Is it safe to eat after it’s expired?” Sort of a set-it-and-forget-it measure just in case you ever need it.

Hiroshima housed the Japanese 2nd Army’s headquarters and assembly area.

Nagasaki was likewise a major naval base as well as the Mitsubishi shipyard and arms works. They were not merely ‘civilian targets’.

Graphics for the ionizing radiation was very questionable. Fission is not ionization. Dissolving salt in water is ionization (and you actually need these electrolytes to live). Electrons constantly join and leave atoms, that’s just chemistry. The “bad” ionization, which typically takes the form of reactive oxygen species, can react with things like proteins and DNA, hurting structures. Great video overall though! Sincerely, a chemist

Its nonsense to say that Iran wasn’t building a bomb yet say they were taking the steps necessary to quickly build a bomb. Those are the same thing. Not building a bomb is not taking steps. Your explanation of duck and cover, explaining its marginal usefulness, was excellent. In the midwest, we do the same for tornadoes, which is similarly only marginally helpful. A point you made but could have made stronger is to describe how long and how much the US bombed Japan demanding their surrender in early 1945. They wouldn’t surrender even tho the US firebombed major cities and killed hundreds of thousands. It was staggering how stubborn they were in not surrendering. In fact, after Hiroshima, they STILL didn’t surrender… it took Nagasaki three days later to seal the deal and end the war. Let’s hope the world never comes to that type of war again.

It’s extremely weird, because the thing that Israel was accusing Iran of doing was enriching uranium to 60%, which is, as he himself says in 13:25, way, way, way, higher than the 3% necessary for civilian usage.
So, in fact, they spent hundreds of millions of dollars if not billions of dollars enriching it towards weapons-grade uranium.

Military target or civilian target strikes me as a false conundrum between two absolute schools of thought. There were certainly military targets very near large population centers where the military installation could have been eliminated while simultaneously putting the maximum number of eyes on the event for maximum psychological effect. Dropping it dead in the middle of a city for maximum deaths may in some ways minimize the psychological effect as I’ve found the dead are categorically difficult to impress.

Sundial was simply a thought experiment with a bet behind it. Some scientists thought Gadget might set the atmosphere on fire. So they did the calculations to see how large a nuke would need to be to do that (fission, not fusion. Also fission would be impossible since it actually does have an upper limit of 800 KT iirc) The bomb would be the size of a large skyscraper. For fusion bombs there’s an upper limit but its not humanly possible. At least not with current tech and resources. You’re working on stellar scales at that point.

AFAIK, Einstein didn’t write the letter. It was written by Leo Szilard, who convinced Einstein to sign it and to send it under his name.

While the US military recovered the remains, today, 60 years later, the US goverment has not yet properly decontaminated the area, which still remains fenced due to the risks.

I’m guessing many here are too young to relate to the “trauma” caused by growing up during the cold war. Especially here in Europe with the proximity of physical conflict. So many scary moments in the 70s and early 80s, both in media and fiction. I can’t even imagine the generational trauma Japanese people has had to struggle with. Then Chernobyl happened and it was scary all over again, with cesium-137 landing on Scandinavian soil and seeping into flora and fauna. The fear of immediate annihilation surely affected “our” psychology, for better or worse. I think that in many cases, it made us more likely to function in a crisis as well as giving us very a pretty dark sense of humor. 😀

I thought he misspoke when he said Sundial was 10,000 MT but no, Teller really wanted a 10 gigaton bomb. Such a device wouldn’t be feasible to transport anywhere due to its size so it would probably be used as an exterminatus type last resort.
It makes me wonder what will happen when antimatter production becomes efficient enough to make antimatter bombs. Just 1kg would be enough to make a blast similar to the Tsar Bomba, 200kg and you’ve got Sundial.

Physics can show you how to build a bomb big enough to destroy the planet. Philosophy will teach you why this may be a bad idea.
