Okay, let's insert a "permanent settlement of" before "populations".
If the Chinese actually did land in pre-British Australia (which is not as yet particularly close to certain), the stories say they didn't stay long or do much.
Of course, that's what this is all about. Just because it's not known doesn't mean there isn't evidence hiding away out there. So I'll be watching for geometric shapes in my google earth explorations. Maybe I'll find the foundations of a 17th century (or ever 1st century as some (probable nuts) claim) Chinese city.
I'm in Australias capital city - up in the mountains a hundred or so kilometers from the the nearest natural body of water of any noteworthy size - the Pacific Ocean. Not too many middens this far inland - what we've got to watch for is cave paintings.
Anyway, an aboriginal would have trouble claiming the land I live on - it's an exclusive residential crown lease (as all residential properties in the ACT (Australian Capital Territory) are.
Not much to be found here. The Romans didn't find their way here, nor the Greeks, nor the Vikings. No populations with higher technology than the boomerang, spear and woomera (that's the spear throwing tool, rather than the rocket range) here until the 18th century, and those pre-european people weren't much into building buildings of the sort that leave a trace. Even our own civilisation's ruins top out at 200 odd years old, and around where I live only to about 80 years old.
Shoulder launch missiles are generally either unguided or heat seeking. A missile hitting the gas bag would hole it - probably minimal damage, they leak slowly; a missile hitting the hottest part of the ship - one of its lift/propulsion motors - would sort out the motor and probably put a fair few shrapnel holes in the gas bag - neither will quickly down the aircraft.
Also, this aircraft will be (according to TFA) transporting troops and equipment to areas that are relatively safe - those are the sort of areas where heavy lift aeroplanes work now. Heavy lift aeroplanes are far more vulnerable to shoulder launched missiles.
It's been said before and will be said again - this is not a disneyland airship: it will not fly around like a toy balloon when a small hole is put in it; it will not pop if poked with a pin; it will not even sink quickly if half its engines are knocked out and it has been perforated by ten thousand bullets, even if they're 40mm cannon rounds; it will not catch fire like the Hindenberg when flying in thunderstorms (even the Hindenberg's predecessors didn't do that!); it will not even catch fire when hit in the gas bag by those ten thousand bullets - even if they're incendiary.
Did you actually read the post you're replying to?
This post's grandparent never mentioned ballistic missile defence. Not once. He talked only of defence of the airship itself apparently in reference to air to air and surface to air missiles.
The point he was making was that it should be as easy to defend a large airship as it is for an aegis ship to defend itself.
In air navigation distances are measured in nautical miles. In metric countries we just call them "miles" because we don't use any other sort of miles.
I singled out American humans because it is America (both the USA and Canada) which right now is failing to test enough cattle to protect the local people from vCJD (forgot to spell out th acronym before, its variant Creutzfeldt-Jakob Disease). The main reasons for the lack of testing seem to be the cost of the current test and the desire of cattle owners to not have BSE (the "B" in that is, of course, for "Bovine" rather than Bovive as I typoed earlier) identified in their stock.
Not according to either Wikipedia or google.
You're making the mistake of thinking that standard atmospheric pressure is 1 bar, it's actually 1.01325 bar (or 1013.25 millibar)
(and yes, I missed a zero)
Yes, you (Fanblade) and Troon are right, I missed a zero. Goes to show I should have written it with thousands separators: 1 000 000 000. Harder to mess up.
Right you are, I was mindlessly misquoting TFA. As you say, carbon-60 is bucky-balls (which are made of 60 carbon atoms)... nanotubes too? They specified that it was made by compressing carbon-60 - that's where I pulled that from.
Carbon^60 as an isotope would be quite unstable indeed!
Nope, no good for ringworld either, you need things strong in compression and tension for that.
Hard is good for scratching, cutting, abrading, resisting scratching, resisting cutting.
It's no good for avoiding chipping breaking or crushing - although I suspect there is a correlation between compression strength and hardness.
What I'm hoping for is a material such as this with excellent hardness, but also good optical properties and easy manufacture into large pieces of arbitrary shape. That would be good for lenses for telescopes, mirrors (telescopes again), spectacles (glasses), car windscreens, spacecraft windows... Imagine it - glasses that never scratch!
No, it's not. It's made of the same stuff as diamond - carbon-60 - but it's a different crystalline structure, just as graphite is a different crystaline structure to diamond.
Not stupid at all. Many people were infected by eating british beef infected with BSE (Bovine Spongiform Encephalopathy(mad cow disease)). No one has been infected by eating Australian beef, there have been no reported cases yet in North America (although infected animals have been found there).
Quarantine seems to be working well for BSE, so infection rates are significantly different between different western nations.
According to New Scientist magazine there's been a blood test for BSE (Bovive Spongiform Encephalopathy(Mad Cow Disease)) since 2003. The more tests out there the better, of course. Better tests mean quicker testing, means more US cattle tested, means fewer cases hiding, means fewer cases of vCJD in american humans.

Such "intelligent" volume controls exist. I had a Holden (Opel) Astra with automatic volume change based on speed.
I was planning on my next car being a VW - with a bit of luck there'll be a few good VW USB hacks.

I guess you can at least pick up fuel on the way home.
An important fact that many hard drive sledgehammerers miss is that the drive should be placed on its side - so the platters are vertical.

Yeah - been spending my time catching up on a few years of userfriendly.org.

Yep. But somehow I still got +5 informative ;).

Probably not. Hardness does not equate to tensile strength. Tensile strength is what you need for a space elevator.
You'd probably still use carbon, but nanotubes rather than nanorods.
100000000 Pascals. It's a unit of pressure. It's equal to 1000 bar or 29,529.99 inches of mercury
