I prefer to believe that Wan Hu existed, and that pieces of his body and/or chair made it to space, because the alternative is that the drat Nazis were the first to send an object across the Kármán Line.

LOL, wrong manhole cover. It's ok, had a good laugh. It possible the nuke cover made it out, since it is moving so fast it doesn't spend much time in the atmosphere since it when straight up with so much speed so it might not heat up enough to destroy it. At 30Km per second it would have left the lower limit of our atmosphere in 3 seconds. It would leave the thickest part in 2/3 of a second. I say it got out.

http://io9.gizmodo.com/no-a-nuclear-explosion-did-not-launch-a-manhole-cover-1715340946 apparently the guy doing the math that came up with "6 times escape velocity" didn't account for air or gravity because he wasn't actually interested in what the cover would do, just what the blast would do. also this was a 900 kg metal cap welded to the shaft, that's a hell of a manhole cover!

At 3~6 times escape velocity gravity doesn't have a chance to react, so it is safe to leave that out. We don't know how air reacts at that speed, it could have very well formed a bubble of air formed by air that literally had no chance to get out of the way like a conventional sonic boom protecting it. If there was a force that would destroy it, it would have been the spinning causing it to fly apart. It most certainly would have spun.

It’s phrased poorly, but the point is sound. An object going straight up loses 9.8 m/s of velocity every second, at altitude zero. If you go up 130 km in just two seconds, you lose less than 0.015% of your speed. That rounds to nothing.

It is still only decelerating due to gravity at 10m/s at ground level vs 30~60Km/s. It is why rockets don't just slowly push their way up. You go as fast as possible to you spend less time fighting gravity. You still need to satisfy Ep=MGH, but if you have escape velocity that energy has already been covered.

Surprise Giraffe posted:What the gently caress is happening there? As I understand it: With the manhole sealed, the gas/oxygen balance in the pipe is poor, so the gas can only burn slowly. The combustion produces enough pressure to lift the manhole a few feet into the air. Once the hole is uncapped, air floods the pipe until the balance rises to the point where a much more rapid reaction becomes possible, and since there's already a fire going that happens instantly.

nomad2020 posted:Dear forum users, About 30 years ago the Victorian (Australian) state parliament house had to install new handrails on the main marble stairs because political reporters, during late sessions, had taken to getting drunk and "ottering" headfirst down the foot-wide railing and several had come off the end at very hight speeds and hosed up very expensive works of art. And pot plants. And the walls. And themselves. Things came to a head when certain career politicians were alleged to have started doing it as well during breaks from their late night sittings. I'm guessing the politicians and reporters took turns flying down the railings in a "I'll keep silent if you keep silent" gentlemen's agreement which ended up with several people hospitalised with everything from concussions to broken legs and arms.

^ ^ ^ No hardhat! Violation! ^ ^ ^ ChickenHeart posted:That said, a decent chunk of safety procedures followed today have their origins in stupid, avoidable accidents from yesteryear: MedicalDeviceSafety.txt Seriously, pretty much every safety feature, alarm, interlock, lockout, etc... on any medical device is there because at some point in the device's history, some nurse/doctor/patient/patient's family member/janitor/random looky-loo hit a button they weren't supposed to, or turned something off that should be on, or on that should be off, etc... One of my specialties was anesthesia machines, and basically every generation in the past few decades has had a new safety feature that at some point engineers and doctors said wasn't needed because "That's not necessary! The anesthesiologist knows what he's doing! Things like... The knob to control Oxygen flow has to be both larger and have different knurling than the knobs for nitrous oxide and air. This is because on at least one occasion, a doctor was looking at something else, either the patient, or a life signs monitor (or a magazine), and just started turning the knob up to increase O2. But it was nitrous, and the patient was injured or died. Speaking of, the flow of nitrous oxide now has to have a physical connection in some way to the flow of O2. The ratio can never more more than 3 to 1 O2 to N20. This is because once (possibly multiple times) doctors increased the nitrous flow too much and the patients didn't get enough O2 and were injured or died.

Can you provide some insight/comment as to what was probably happening here? An oxygen output was attached to a patient's catheter causing their bladder to burst There have been a bunch of government enquiries which have shown student nurses working unsupervised and shift nurses working double and triple shifts but no real explanation as to what happened. Working in hospitals, I can't imagine the cascade of events that would need to occur for this sort of mix-up to be a risk. I wonder how much different sized knobs or safety features would have made a difference...
