      But I know what you mean. Often times, all the work that went into something like these big events is more interesting. I have watched so many videos about Apollo preparations, how the astronauts were trained, the construction of the equipment for that reason.
      But for years I always wondered about this before learning of the sounding rockets. In pre-internet days, searching for answers was either difficult or very time consuming.

      Honesty is the best policy !!!! BTW smoke rockets are used only in test detonations. In actual war they would not use them. Obviously . . . the rockets are useful only when high speed cameras are set up to record the event. Clearly that means they know ahead of time exactly WHEN the explosion will happen. In war that would be impossible.

      The lowest part of the rebounded wave nearly doubles the energy of the expanding ground wave…the rebounded energy combines with the original expanding wave at ground level. This is called a Mach wave and one of the reasons that airbursts have more lethal shock waves at ground level. Ground bursts provide more of a radioactive cloud, but less of a expanding shock wave. 😮

      In the case of North Korea, when the Soviet Union collapsed, there were a lot of scientists in Ukraine where a lot of the research was done, were suddenly without work. So, they went to work for North Korea. Taking decades of nuclear science with them.
      In the case of the USSR, they were working on their ownbprogram, but they got a huge headstart from information stolen from the US by spies. People like the Rosenburgs helped the program come along a great way like that.
      Those are the only two countries I can say with any assuredness how they developed nuclear weapons. But judging from the pattern, I think it's safe to say other nuclear powers that shouldn't have them like Israel and South Africa probably developed their weapons using stolen information.
      I'm pretty sure that the UK worked with the US to develop their weapons. And I have no clue how France got the bomb. They seem the least likely developed country to have nukes.
      Of course, there's a lot more to building nukes than just knowing how. One of the hardest parts is purifying uranium ore into weapons grade uranium-235. Which requires massive, extremely fast, extremely precisely built centrifuges made out of special, high strength metal alloys since they spin so fast that normal materials would just tear themselves apart. You need a lot of information and special materials just to process the uranium. Then making it into a bomb from there is actually fairly straight forward by comparison. But the materials and methods for making these centrifuges alone are not easy to get. Then you need people who know what they're doing.
      Just read about the accidents at los alamos while the US was developing their bombs. There was one incident in which a researcher had a vial of plutonium in liquid form explode in his face. Covering his face and inside of his mouth with what at the time was most of the plutonium that existed on the planet. Only a few ml. But you bet the government wanted their plutonium back. After all was said and done, dude had to process the plutonium out of his contaminated clothes, things in the room that were contaminated and bodily fluids, vomit and uring I believe. He never got any radiation siclness or poisoning from the plutonium. But he had a hefty enough dose that plutonium was detectable in his urine until he died.
      Oh yeah and there are the demon core incidents. Those are a classic.

  • @SirFloofy001
    @SirFloofy001 Год назад +930

    Whenever you see the shockwave hit houses it always looks like a huge blast of wind, but watching those smoke trails you understand it not wind its more like every particle of air suddenly wanted to exist 10 feet to the left and they're taking everything with them.
    Edit. Okay so explosions are chemical reactions, two or more ingredients react with each other which creates heat which continues the reaction. But chemical reactions do not remove matter, they simply convert it to a different form, so if you have a fist sized ball of explosives and it all explodes then you are left with a ball of super dense super heated gasses that is equal to the mass of the ball but wants to take up much more space, so those gasses expand outwards but they cant break the speed of sound so it becomes a pressure wave expanding outwards in all directions. But as soon as the pressure wave passes over you the air stops, there is no energy imparted into the air it is simply trying to make room for the sudden expansion of hot gasses.
    Nukes work the same way except instead of a chemical reaction turning solids to gasses its atoms splitting into two with some extra bits flying off, plus breaking the nuclear bond releases much more energy so everything gets much hotter and more heat equals more expansion equals more pressure and bigger boom.
    The wind caused by nukes is not from the explosion but from the air expanding to far and springing back combined with a massive updraft from the fireball rising into the upper atmosphere.
    Fun fact, any atomic bomb footage you have seen where the fireball seemed to have fiery legs its because the nuke was on top of a tower which was supported by cables and the heat has vaporized the cables so fast they basically explode.

      @That-Google-Guy Год назад +8

      @@sidv4615 of course! If you watch some high speed camera videos, especially ones where they want to show movement per frame (like a bullet), they may have a wall in the background with either a ruler or a set of black and white lines that are ruled equally (ie all of them are 1 inch long) so you can see how many inches it moves in a specific amount of time.
      So if the bullet has moved 3 inches in 5 seconds with a frame rate of 10,000 frames per second, you can use some algebraic equations to find out exactly how fast that bullet is moving. I’m not smart enough to do that math but that’s the long-and-short of how they can derive those numbers.
      SO with the nuclear bomb, if shockwave passes three of those smoke lines in 5 seconds at 10,000 frames per second, and those smoke lines are 100 feet apart, they can calculate the speed of the shockwave, or whatever else they want to measure.
      I hope that makes sense, please ask more questions if you need more info :)

    That was something that I often wondered as the vertical orientation and consistency from ground to maximum elevation made no sense if it were related to the explosion. Of course with high speed cameras you don't see much prior to the detonation so I always assumed that there was some phenomenon that I just wasn't aware of. I never actually realized that these were only visible with test runs.

    Thanks for that. Often seen the lines but didn't know if they were somehow an artifact of the explosion itself or something else. Good explanation of the "double flash" as well. A former boss I had many years ago helped design protective "flash glasses" that would protect an observer from the second flash (which does most of the damage). The protective "glasses" or actually goggles, would have to sense the first flash, then fire an extremely quick acting "squib charge" which would then drive a "shutter" closed to protect the wearers eyes.

Or, to put it in real world context, you could think of my initial notion as the windsock at an airport.

    there is a more important question: in various TV-films or series, there are terrorist organisations that claim to have a nuclear bomb. and when they fire one, there are those lines.
    the simple question: why so some terrorists need those smoke rockets? do they really care that much? "we will explode a city, but for scientific purposes, we have set rockets up that allow you to learn from it"

    That one drove me crazy for years...
    I knew it couldn't be part of the bomb itself but I couldn't figure out what caused it or if it had a purpose.
    The regular distances between each 'marker' suggested it was some measurement tool...but for a 'nuke' that where they measuring I knew it wasn't "power".
    In the end, I could only manage "size"

      I love the way Feynman described it.
      Gravity is the weakest of the fundamental forces, it takes a whole planet to weigh you down. The forces we see in our everyday lives can shape the world in dramatic ways, but there is much more hidden beneath the surface. When you feel static electricity, that is the effect of an extremely minuscule amount of charge, accumulated by the triboelectric effect. When generating electricity, we humans concentrate a very small amount of electrons to do our bidding, the weight of the entire internet is akin to a strawberry. On very small scales, we can still see this power, when you touch something you are coming so close to it that its electric charge pushes back on you. However, the strong nuclear force is even stronger, but once again, its constituents are in numerical balance, hiding away the fact that extreme energy exists in all things. To unleash this power from only a dollar bill’s weight of fissile material created the mushroom cloud over Nagasaki. But everything everywhere stores this energy.

    MY FATHER who was in the Navy in the late 1950's. Saw 12 atomic bombs tests up close (a human Guinea pig). They called it Operation Hardtack in the Pacific. My father said they gave him special dark Goggles (That I still have) and was also told to turn away from the blast and put his arm in from of his eyes. My father said he was a 2 man navy boat in the ocean. When the blast went off. There was so much radiation that included x-rays. He could see through the goggles, his arm, the boat and see the skeleton of the fish in the water. My dad had both eardrums blown out and eventually died of cancer 20 years ago after being almost totally deaf for 40 years. Waiting for his VA benefits hearing to increase his disability from only 15% to 100%. He never lived long enough for the hearing. The U.S. Government had stalled him for years. That was there plan. To wait for him to die 1st. My mom is still alive and could use the 40 years of back pay they owed him.

    • @Guido_XL
      @Guido_XL Год назад +1

      @@n1ckster055 I am not so sure. Gamma-rays can induce X-rays of lower energy, when they hit material. That is why we had lead-layers inside a cassette of X-ray sensitive film to photograph objects as part of an X-ray inspection. The lead would absorb the higher energy rays from outside and turn them into lower energies, as well as free electrons that would amplify the projected image on the film.
      In theory, a human eye is indeed insensitive to small wavelengths above the blue bandwidth into the ultraviolet, so that X-rays are certainly not triggering the retina as visible light does. But, gamma- and X-ray radiation may cause secondary radiation. I don't know as how this might have worked during a nuclear explosion though, I never thought of the ways that unintended projections of images may occur under those conditions.

    • @Guido_XL
      @Guido_XL Год назад +1

      @@n1ckster055 The trick we applied was this: we attached a stack of several cassettes onto an object that we were supposed to inspect. We set up a Co60 source or a linear accelerator opposite to the stack of cassettes, with the object in between. Inside each cassette was a different combination of either a single film of a certain speed, or the same film, but sandwiched between lead-layers (or even stainless steel in some cases). The cassette could therefore contain only one film, or multiple films of different speeds, either combined with amplifying layers, or without any amplifiers. The idea was to cover a multitude of different thicknesses that we had to inspect in a single exposure. That saved a lot of time and effort.
      Obviously, we only had to go through that kind of tedious effort in case of really thick steel objects. Smaller objects could be more conveniently inspected with a single paper-wrapped film, which was of a certain speed and was sandwiched between layers of 0.027 mm lead, deposited on paper. We used portable X-ray sources for that, or Ir192 radioactive sources, which were very mobile to deploy in the field.

    This is one of the few things I sort of “common sense’d” my way into figuring out when I got older. When I was a kid, those columns confused me and I always thought it was some crazy phenomenon occasioned by a nuclear detonation. Only later did I think “oh wait, they’re clearly launching rockets”. I had no idea about the specifics…I figured they were trying to gather data at certain altitudes or something along those lines. Sometimes reality is a lot more interesting. This is definitely one of those times…

      What you are referring to is a ‘ground burst’. Air bursts are more efficient because you get increased blast radius with less lingering radiation.
