No there isn't much pressure to release spectrum. This scheme was dreamt up when telecom companies were on the up. Since then, we've had the telecoms slump. Spectrum auctions all round the world are failing, and those who paid big money for 3G spectrum are struggling to stay alive.
The UK is a very good example of what will probably happen. The 405 line standard was introduced in 1936, and replaced in 1964 broadcasting on the 625 line standard was introduced. BBC2 was only ever broadcast on 625 lines, and colour was added in 1967. So we have better image quality, and new channels, and from 1967 colour, which is an obvious improvement for even the least technical person. Yet the last 405 line transmitter was turned off in 1985! Now we have a much higher number of working analog TV's, much longer life for an individual TV, and no easily grasped advantage for digital over analog (and some advantages for analog over digital, such as faster channel change times). It would be unwise to assume analog can be replaced with digital any faster than 625/PAL replaced 405 line.
There is no single specification for movie screens.
First, all ratios can be simplified so that the right side is 1, this makes it easier to compare. 4:3 is 1.33:1 and 16:9 is 1.77:1.
Originally, after a period of experimentation, most films were filmed in Academy. This was 1.37:1, but after they added sound, it was reduced to 1.33:1. This is why TV's are 1.33:1 - they chose compatability with the majority of movies created at the time.
Then, in the early 1950's, there were are great number of competing widescreen formats. Vistavision is 1.70:1, CinemaScope is 2.55:1, Panavision is 2.40:1, Todd-AO is 2.22:1 and Cinerama is 3.0:1. All of these formats are basically dead, with Panaflex replacing Panavision and used for the majority of modern movies, which are shot at 1.66:1 or 1.85:1.
All of these aspects are however approximate, as it's going to vary depending on the exact lenses (or settings in Panaflex and other cameras with variable lenses) used in the original shoot, the transfer to the print, and the projection, and also on the matting - how much "blank" space the projectionist cuts out of the image.
For some of the weirder formats, such as Cinerama, there isn't a single aspect ratio - the screen is curved, and your aspect ratio is going to vary depending on where you sit in the cinema.
Actually it's sickle cell anemia for people who's genetic background is from maleria areas. That means not only African, but also Indian, Arabian, and Mediterranian countries.
No, there was an atmosphere before life. It wasn't like our current atmosphere though. It was high in ammonia, methane, carbon dioxide, carbon monoxide and water vapor. When the blue-green alge came along, they started converting this atmophere into our current atmosphere.
By 2 billion years ago, as far as we can tell, life was stablized in it's current chemical composition. If you want to get to the early days, when life would be experiementing with novel chemical forms, then you're going to have to go much closer to the formation of the planet. r
Of course, if you do limit the number of connections from a single IP, you may be limiting seperate clients who happen to be coming from the same proxy. This is particularly common with large ISP's, eg AOL.
HTTPS does provide choice of encryption menthods, though not all clients do, or make it easy. With Opera, you choose File->Preferences->Security->Configure SSL2 or Configure SSL3, and you get a list of protocols you want to enable. When the SSL connection is established, the two ends share a list of protocols they support, and the highest common one is used, or you get a failure. So if you want to force triple DES, you simply disable every other protocol, and that's what you get.
In my experience disabled people generally have better skills than average. They work very hard to overcome their limitations and succeed. And of course, physically disabled people have exactly the same range of IQ as non-disabled people.
I think it's a mistake to think of "the UN". The UN is really a loose grouping of many related organizations. UNESCO and UNHCR are very different to the Security Council and the General Assembly.
It sounds like you've been to London. Other parts of the country have a very different public transit system.

Physics ppl have said that the low G fire experiments are useless. Nothing learnt which they didn't already know. The other stuff on this mission are laughable. School kids cannot design a cutting edge experiment.
Planes are very different to spacecraft. The ratio of fuel power/weight is good enough that we can carry all the fuel without throwing away tanks/boosters. The engines are good enough that they don't require huge amounts of maintence. Some things just work better as disposible - you could in theory make an alumnium can that could be refilled, but no-one does.
It's possible, but pointless. Satellite technology is changing fast enough that it's better to launch a new bird than try to repair the first one. It's similar to the motherboards with 'upgradable CPU' you see occasionally. No-one really upgrades the CPU, because the needs have changed.
I disagree. The problem hasn't been money, it's spending the money on the right thing. Shuttle has been a money pit. If they'd continued with disposible rockets then they'd have had more than enough money.
It's not just a cost to orbit thing. Undersea exploration has a very small cost to submerge weight. The cost there is getting a support ship above where you want to go, and then it's essentially the same if you put down the smallest ROV or the largest manned submarine. But the best stuff happening there is with ROV's. You can leave a ROV down longer than a manned sub and you can take a risk with a ROV that you'd never take with a manned sub.
You can if you're going in the wrong direction. Reusabilty is a mistake. It costs more money in the design phase. It costs more money in the build phase. It costs more money in the launch phase. It also forces you to design a system with less safety than the disposible systems.

Grey book addresses were used by non-academic users too, but since at the time the internet was much smaller, there were very few.

a patent on a particular widget, but every
possible similar widget.
Ronco can take a patent out on their electric dehyrator, and no-one can copy it. But you can make your own electric dehyrator on a different design.
With software patents if you patent one-click or frames or anything else, then no-one else can implement it at all.

Discovery is currently undergoing a refit, so it unavailable. It's next scheduled flight was in 2004.
What a pity that the science is second rate, and not an advance at all.
The 7060-H50 was introduced in 1999.

So only do manned missions on those which justify it. And 'how do spiders spin webs in space' don't justify it.

Very badly. The shuttle isn't really a reusable craft, it's a refurbishable craft. After each flight it's torn down and rebuilt.
