Always heard of the guys who witnessed the Trinity test talking about the colours from the ionization but the first time I've seen it so clearly in any test.
The people who saw the original explosion at Chernobyl and its very early aftermath reported exceptionally intense and varied colours in the stream of fire directly above the shattered reactor. Some writers have tried to pooh-pooh these accounts and say it was just light from the roofing-tar fire reflecting off the smoke from burning graphite... However that is very much not what the eyewitnesses reported.
No, The people who made the Oppenheimer movie should just stop making movies altogether because that movie was a total pile of garbage. My 3 year old retarded cousin could make a better movie using Windows movie maker v1.0
@@atomcentral The glow and strange luminosity of the fireball is what makes a nuclear explosion look nuclear. The roiling black and brown clouds are from oxide formation?
All that jazz about Nolan using an actual bomb for the movie, only to be actually a giant fart. I feel like since T2 in 1991, Hbombs and nuclear devices in general have never achieved the intensity of that scene. It's kinda weird as technology progresses and we keep getting better footage (thanks to our lovely atomcentral), nuclear explosions keep getting worse (those clouds in the Fallout series are butt ugly). Nolan was probably the only one who could have made a cinematic nuke a reality, but he unfortunately didn't deliver on that one. The only recent one I think holds up really well is the Trinity explosion at the beginning of Twin Peaks S3
On the bottom right of the video screen is a gearwheel that says hd on it. Click on that and set the replay speed at .25. It is defintely worth it. Seeing the blue atomic light of death in a cloud the size of a city is truly astonishing to see in slow motion. Some of the deepest blue ever recorded.
It always puzzled me why folks associated nuclear weapons radioactivity with 'green glow', when it is blue. I guess we can thank radium painted clocks and Trinitite for that?
This is not Cherenkov light. Cherenkov light is blue, not violet, and a beta particle would need to be traveling more than 99.97% c in air in order to exceed the speed of light in air. Betas from radioisotope decay to not achieve this energy. The light is from direct airglow ionization caused by gamma and beta radiation ejecting electrons from air molecules and then the light is emitted on subsequent ion - electron recombination. The color is violet for the same reason glow discharges in partial vacuum are violet such as in Geissler tubes, the same energy levels are being excited.
Wow that's incredible! Was this footage shot using a special kind of film or something to more easily see the glow, or was this enhanced in after effects or something?
I think for reason that Eastman Color Negative seemed more sensitive to that effect. Also many of the black and white films shot of these tests used yellow filters to hide the glow.
The original film rotting away in some vault is public domain, the scans mr Kuran made are not. He spent countless hours doing the official way of requesting access, hauling digitizing equipment there and manually touching up the frames to get rid of the dirt specs and worn colors of the originals. He used to upload whole videos with just a tiny watermark in the corner but literally hours after uploading the same video just cropped to get the watermark out, plastered with their own watermark and with some stupid music behind it without any attribution would be uploaded on 3-4 other channels.
I apologize but it is an investment to me. I don't grab stuff off the internet, I research and scan or have the material scanned and do the best I can to fix it. I've had calls from places like CNN who say they should just be able to take it from me without going to the labor, time and expense of finding it and making it look good which is why they like it in the first place. I have to do that or I'm just working for free to companies that can afford to cover some expense.
@@atomcentral CNN of all companies should know about properly licensing content. I agree completely with what you've done because declassification and FOIA requests take time, on top of scanning and cleaning up the film on expensive equipment.
I don't remember what test this was, but the blue glow was very obvious in the original footage. One of my favorite tests. I don't. Really have a problem with upscaling film footage to show more vibrant colors. This is probably about what it looked like in person.
not AI, is actually a Plumbbob test from 1957. The glow is often not seen in black and white because they often put a yellow filter in front of the camera to hide the blue glow.
Well... it looks like the NTS to me with the mountains in the background. The explosion and cloud itself appear very like Trinity, therefore probably a low-yield fission test. Very early 1950's would be my guess, perhaps testing a primary for one of the early hydrogen devices. The haircuts also speak of that era. However we can see structures as well, which could be the remains from Apple-2, which would mark it as post-1955. Those are my guesses. As for 'AI'? I doubt it. Kuran has done most of his work optically and in analogue. Even when producing upscaled digital material he is extremely careful to remain true to the original negatives as far as he possibly can. I think this is just one of those sadly few moments where reality for _once_ is as wonderful as SF. It really _did_ glow like that due to the colossal release of radiation.
@@atomcentral Just imagine being so... passe, accustomed or even tired of this magic that you take steps to not have to see it any more... I know they were probably doing to improve the basic clarity of the image, but still that story makes me rather sad! What I would give to have been stood with those two chaps when it went off and to have seen it with my own eyes...!!!
type upshot knothole Annie in the search, you can clearly see the blue glow around the mushroom even in black and white. this is not AI, it’s nuclear physics.
