I thought that plutonium was so loving toxic, that if you were to touch some you'd be dead before you could lift your finger off it. A guy in a Grateful Dead t shirt told me this so it must be true.

If you're being economical with your Plutonium, you can get by with about 5kg, but then you need a heavy tamper (likely U238) and a levitated core, so that the core has more inertia holding it together during the actual fissioning.

If I surround it with an infinite reflector I can get to 3.975 cm radius, which is 5.213 kg. These values are probably not 100% correct for reasons, but I'm not going to correct them. You should not try to eat a 10 cm diameter sphere of plutonium. Olothreutes fucked around with this message at 23:36 on Jan 1, 2017 |

wolrah posted:What would give you this idea? Parking brakes work equally well in both directions. In most vehicles they're just a cable-actuated drum brake (generally inside the rear discs) which works exactly the same as the rear brakes still to this day found on cheap cars. On a few higher-end vehicles where the rear disc doesn't have the space for this it's an additional cable-actuated caliper. Technically true, but with every rear-drum brake truck I've owned I can easily drive in reverse with the brake engaged but it there's enough stopping power to stall the motor going forward.

That's because the reverse gear typically has lower gearing (so the motor provides more torque) than even the first forwards gear.

I can't remember, is the skyway bridge the lift bridge going into Hamilton or is it that newer 6 lane one or whatever? the lift bridge was my favourite place to hang out as a kid until I got yelled at by the operator for trying to ride it up when a boat was coming. edit: looking closer at the picture I can see it's the latter bridge

chitoryu12 posted:From what I remember, Tex Grebner (the guy who shot himself) explained that he did it because he was using a different holster than he normally did. The SERPA he was using requires you to push the button and then pull up on the gun; if you pull up and then push the button, the gun stays locked. Tex was used to a holster with a different mechanism so he pulled, pushed, realized it wasn't coming out and tried to curl his index finger to get more leverage, and so as the gun came out his finger slipped and pulled the trigger.

That's not entirely accurate. You can pay Microsoft arbitrarily lots of money to support a special snowflake version of an old OS. Its an option militaries and digital controls companies often take because of well developed risk analyses and justified because "well its an internal operating system, we don't need to worry about network vulnerabilities." Its like the same reason electronics used in state of the art military or control equipment have raw specs comparable to consumer PCs from 15-30 years ago.

It's almost certainly Windows Embedded, and there's a zero percent chance the sub is publically visible on the internet. Nobody is installing internet explorer toolbars on a nuclear sub. It's also not at all shocking that specialized military equipment is running an older version of Windows than a modern home computer.

Running Windows in an industrial control environment is fine. Any suggestion that it is inadequate is just someone speaking from a lack of any real, practical experience. While I cannot say I like that the military is still running XP for things like their submarines, they likely have done a risk assessment and it is far from unlikely that this is an unsupported environment. These systems are unlikely to ever touch the Internet especially when they're below water.

the russians will just drop some USB sticks in the car park by the docks when the submarines are in dock. someone will plug it into the sub.
