seals between the initial modules. These are necessary to keep the station airtight, and replacing them would mean disassembling half the station.
isn't that what duct tape is for?
Weren't they going to crash the ISS into the atmosphere to dispose of it at one point? That would have been incredibly stupid.
Nope, eventually that will be it's fate.... I believe that the current project only goes out to 2025 which puts the re-entry in 10 years or so unless it's been extended.
If we're serious about missions to Mars (and potentially elsewhere) then I think that we need to keep ISS running. Not to do so kind of sends out the wrong message....here's something that's within a few dozen hours of travel time of Earth but we can't maintain it. We're sending you an order of magnitude further away...cross your fingers that you won't need any help.
DC is just safer to work with
That depends...if you touch a live DC wire with your palm, your hand will naturally contract and grip the wire. Same thing with an AC wire, and your hand will be repelled. With enough power, both can still hurt like hell, but the latter is the better option.
The second rule is "treat every circuit as live, even if you know it is not" So yes the electrician was not taking the proper precautions if he was not treating the circuit as live.
Coincidentally, last night I was talking to my father who worked as an electrician/electrical engineer for over 30 years. He said that back in the day, it was quite common for sparkies to work on live kit....they knew the cables were live and knew how to respect them and what precautions to take. This wasn't just restricted to the standard 240V supply (c.f. the 110V used on the other side of the Pond) but also to distribution kit, running well into the kilovolt range. For example, bare end of armoured cable going into a substation being wiped and jointed by hand.....carefully, very carefully
Ok, why do they even need to know if the car is in MOTION at all just to play music??
My car audio system certainly hooks into vehicle telemetry - it automatically adjusts volume according to speed, to compensate for road/wind noise. Works very well.
Facebook Engineers Have Solved One of Education's Biggest Problem

That's my plans for the weekend shot to s**t then....
He should be executed for treason.
Snowden needs a very slow and very painful death.
Whilst I don't agree that it necessarily needs to be slow and painful, I agree with your sentiment.
The trouble with a lot of self-made men is that they worship their creator.
