In fact, the battle of Hastings was between the Normans (from Normandy in France, though of Norse - 'viking' - ancestry), and the English Anglo-Saxons.
The Anglo-Saxons were Germanic peoples who colonised England after the departure of the Roman legions (though they had been raiding previously). It appears the celtic britons integrated with them (as slaves/lower-caste), and some norse got mixed in as well (the Danes ruled much of England not long before, and there'd been several danish Kings of England 50-odd years previously).
The name 'England' comes from one of the main Germanic peoples who colonised England during the 'dark ages' after Rome, the Angles - the other main ones being the Saxons and the Jutes.
All in all, Western European history of the times got kindof complicated - which as very little to do with sunspots of course...
Japan is hardly in the running for a low-wage callcentre or similar; it's one of the most expensive countries in the world, with higher wages than most of Western Europe! They are more likely to be the customers of such services, and the owners of the multinationals doing the farming out.
I believe the point the orinial poster was making is that infrared-frequency EM radiation often isn't very useful; if this was shifted to visible frequencies, the amount of useful energy would increase (though the total energy remains constant).
However, infrared photovoltaic cells are already availible, so that doesn't actually help this application particularly.
Actually, I can see a perfectly valid basis for Spatial mapping being partially evolutionary.
I don't know the science, not being a neurologist, but it's clear from comparing humans to other mammals that brain functions do have a genetic foundation - the sizes of the different brain areas, and maybe other factors relating to their performance. No matter how well you teach it, a chimp can't think on the same level as a human.
If there's an area of the brain that handles spatial mapping, the size/effectiveness of this area could be affected by mutations in the same way as areas that handle speech etc. Men with a small beneficial mutation in this area will perform better when out hunting etc, and be more successful. Women wouldn't gain as great an evolutionary advantage from this, so these mutations wouldn't affect them as much, while social-skills ones would.
This is not about 2D desktop navigation, but about orientation in a 3D environemnt such as a computer game or a 3d design program. It appears be that the restricted field of vision with a small screen makes it hard for women to build a mental map of the enviroment and locate themselves within it.
The arcticle speculates that this may be due to evolutionary reasons; men are on average better at spatial-awareness for navigation when hunting, while women wouldn't have needed such skills looking after the home camp.
My point was actually that in order for an infantry weapon to be used effectively, the user needs to be able to see the target; if he can, then clearly light, and hence the laser, can pass.
Admittedly, its power may well be reduced, and the beam not as focused as before - and there may be issues with the light reflected back off dust/sandstorms blinding the user.
They are relatively inexpensive, relatively easy to maintain, and extremely reliable. - which also describes longbows of course. It's hard to say what'll happen, and lasers do have some huge advantages, though I agree that the initial uses for battlefield lasers will not be infantry - I'd expect vehicle-mounted systems, for air/missile defence.
The Geneva conventions only outlaw lasers explicitly designed to damage sight or cause permanent blindness - not ones in which blinding is incidental. This weapon is meant to kill people dead, not blind them, so it's all hunky-dorey with the convention.
The recoil may be due to the movement of the CO2N2He gas during the lasing reaction - mean velocity of 1998 m/s. If this is moving backwards, ther will be a recoil forwards (by Newton's 3rd law).
Reflective clothing will not help significantly against lasers; the material wouldn't be able to reflect the majority of the energy. Mirrors are only about 90% reflective, and the remainder will blast through the material in no time.
Dust clouds would be a problem, but this is an infantry weapon; you have to be able to see your enemies anyway.
Gee, I don't know, mister; ever heard of a propeller? That's a set of wings that rotate under water. Get a clue.
Props are not generally wings in the Bernoulli sense as they are deflectors (they produce thrust through being set at an angle, rather than through their curvature). However, the bernoulli effect does still operate fine under water; try waving a spoon around when doing the washing up, it generates a surprising amount of lift due to its curvature.
"A single machine could have multiple languages co-existing for different tasks."
Just as quite a few computers 'round here have multiple OS's installed.
On this machine, I currently have 2 different installs of Linux, and one of Win2000. They are used for different things; one of the Linux instances is for my desktop machine - customisation, and my 'feel' is important. Another is for testing/playing with, while the windows install is for any apps I need which still aren't around on linux (practually none that I use these days actually). I'd suggest that this kind of arrangement is analogous to having differnt languages for different purposes, and is quite common amongst computer hobbyists.
I'd also hope that performance, stablity/security and compatibility are important criteria when selecting programming languages as well as OS's!
As I understand it (not particularly well:-) ), it would indeed - but the Earth wouldn't know the sun'd disappeared, as light, and any other information, is limited to, well, the speed of light..
Thus from the earth's point of view, you could say it goes 'whizzing off' (a slightly dodgey concept in itself...) the moment it knows the sun's disappeared, and instantly from our perspective.
If the people are giving away the software, it's hardly unreasonable for them to requre payment for help setting it up. Consider if it was just a random guy developed a small tool which he thinks should work on Linux, and GPLed it; is he then obliged to provide instructions for doing so without charge, on his own time? What possible justification is there for this? Is donating the source free not good enough for you?
If, however, the guy was charging for the tool, which he claimed worked under linux, then it would be another matter entirely.
In my view, asking for payment for providing the information is quite reasonable, considering, to use your analogy, he's giving you the car free.
The problem is that, once you know, you cannot tell anyone else: 'You shall not to share [sic] the information contained herein with any other party.' You can't tell your neighbour how to open the boot, or your SO come to that. Which is a bit silly really.
It's extremely difficult to compare this with any closed-source application, as a lot of these 'bugs' were in pre-1.0 versions - which never see the light of day in commercial software. Windows 2000 was however rumoured to have shipped with roughly 65000 unresolved bugs.
(and don't bother with the trolls; the population there want to remain british by almost a 100% majority. Mind you, that doesn't seem to be helping in Gibraltar...)
So you make your mirror subsystem disposable, and eject the spent mirrors like shells.
I think the guy's point was that the mirror isn't good for one shot; it'll pretty much vanish, and the laser'll keep going. A laser isn't like a projectile; a projectile is expended when it hits something. With a laser, only the time spent cutting through the shield is 'wasted'; the remaining milliseconds (or even seconds, possibly) of the pulse after it's done with the shield will slice into your fuel/warhead/guidence/crew. Bang.
In point of fact, Concorde is Anglo-french, a joint venture. Though it was indeed a french one that came down, as the British Airways ones had all been modified for that kind of problem to a degree previously.
..For a minute I thought I'd somehow got transfered to my spam mailbox or something.

Yeah yeah, mod me down, I'm not being suitably impressed:-)
Maybe mobiles aren't as coomon in the USA as in the UK, but here roughly 75% of the population have one, and if you're between 15 and 25 quite a few people look at you strangely if you don't (around Cambridge anyhow). They've become expected.
For example, I was meeting my mates in London for my birthday 2 weeks ago; we were all coming in from different areas of the south of England. The day before we arranged a place and time - Victoria at 11:00. Come the next morning, everyone arrives in London, different arrival points, different times - out comes the mobiles> All 8 of us found each other within 20 mins of arriving, despite the 'group' having moved several times between the first and last person - some of whom didn't hear about the meet til that morning.
Trying to do the same on such short notice without mobiles just wouldn't be possible. Mobiles have removed the need to plan - you can just do it all on the fly.
