frozen water displaces more water than when liquid.. when water freezes it expands.
So you answered this yourself. When water freezes it expands, and suddenly peeks out to displace some air instead of water. The amount of water displaced is the same that went into forming the ice, not more, not less.
I can only wonder how high that percentage has to go before we start making plans on how to avoid the posible impact.
To 100%, of course. Now that the asteroid is closely monitored, the orbit can be measured with sufficient precision in a few more weeks or months of observations.
Given that the predicted hit is in 2029, waiting two or three months will not be fatal.
It doesn't install anything, and it's the lightest image viewer that I have ever seen.
It has a function to enable bmp preview chaning the icon on windows explorer. If this function is enabled, looking at a folder full of bmp files will involve reading them all and resizing lots of image, so it might be quite slow. I recommend disabling that.
Yes. The image on the telescope is not a theoretical point, but has a certain diameter depending on the telescope diameter, atmospheric distortion, ccd resolution, etc. So you cannot pinpoint the asteroid position precisely, but only give a bounding box.
Combining multiple observations will give you more data, and you can start narrowing down the estimate. Right now the error on the position, projected to year 2029, is about 200 times bigger than the diameter of Earth, so we say that there's a 1/200 probability of impact. A planet is a very tiny target.
When the precision is sufficient to say that, for example, the asteroid will pass by the left side, it will suddenly drop to zero. If it is actually going to impact the Earth, the probability will slowly going up until it will reach 1.
1/2 hour for 1 GB is less than 1MByte/second, so you must have an USB1 flash card or one of those USB2 "full-speed" that are still 11 mbit/sec instead of 480 mbits.
A real USB2 flash card can download three or four times faster (it will be limited by the flash r/w speed, not the bus), and it's comparable to a 32x cdrom.
It happens in the following case: if selection == "kerry":
votes["kerry"] = votes["kerry"] + 1 else if selection == "bush":
votes["bush"] = votes["bush"] + 2
There's no need. 80% of Spain population was already against the war, and the government went in Iraq anyway. No surprise that it got booted out of office.
"Live" means live from the control room. There isn't any realtime video camera on the Cassini.
The images come from something like a CCD photocamera optimized for astronomical observation. They are saved on an internal memory buffer and transmitted back several hours or even days later. Even if there's some ET waving at it, Cassini would probably not even see it.
Scaled Composites, for example, has demonstrated a suborbital craft capable of barely reaching space for a cost of around $25 million. In comparison, NASA developed and flew three X-15 prototypes with similar capabilities for a cost of $300 million in 60's dollars (which incidentally was considered a cheap program).
With the small difference that Scaled Composites is benefitting from 30 years of technology advancements. I don't think that an equivalent company of the 60s could build three SpaceShipOnes for $300 million.
That's not just the UK. Almost all European countries vote in the same exact way. And no one this side of the Atlantic was able to figure out why Florida's manual recounts took more than a few hours.
Hydrogen was not the cause for the Hindenberg disaster. Hydrogen burns without any visibile flame or smoeke. In the Hindenberg case, what burned was the external paint, which had a chemical composition quite similar to nitroglicerine (it wasn't known at the time).
Even more sad, most the deaths from that disaster were people jumping down while the ship was still in the air. Most of those who remained in the airship survived.
smashed together thousands of galaxies and trillions of stars.
In such an event, trillions of stars aren't smashed together. Some of the galaxies might merge, but individual stars would pass one next to the other with no harm - the space between them is much, much bigger than their dimension.
The main reasons a paper encyclopedia has far fewer articles than Wikipedia are manpower (you can only write so much without hiring thousands of writers) and paper costs and size (who wants a 300-volumes encyclopedia in their home?). CD-rom versions are often transcribed from the paper version or, if only digital, still suffer from limited manpower and limited availble space. Do you know that the complete Wikipedia is already too big to fit into a DVD?
What you sat is that with a heat pump you can make 4 watts of heat out of 1 watt of electricity.
Why don't you run those 4 watts into the heat pump again, hey you've got 16 watts. Now run all those into the heat pump, you have 64 watts. Repeat again....
Quick, patent it before someone else discovers it! Of course you should aware that the US Patent office requires a *working model* before accepting a patent on perpertual motion, so you better start working now.

Your teacher was right on the effect, but wrong on the exact value. The average slowdown measured is about two milliseconds per century.
So 65 million years ago the day would have been about 20 minutes shorter than now, which isn't a huge amount.
This asteroid has an orbit that takes him close to Earth from time to time.
This page from nasa lists the close calls from 2029 on (apparently before 2029 the asteroid is passing far enough that it's not a threat).
I can only wonder how high that percentage has to go before we start making plans on how to avoid the posible impact.

Yeah, of course it was the surface... thanks for clarifying.
So what's the bottleneck here? Poor imaging?
Yes. The image on the telescope is not a theoretical point, but has a certain diameter depending on the telescope diameter, atmospheric distortion, ccd resolution, etc. So you cannot pinpoint the asteroid position precisely, but only give a bounding box.

easy, isn't it.
I sure hope they don't. It would mean that a vote can be traced back to a certain voter.
Doesn't explain the withdrawal from Iraq does it?
There's no need. 80% of Spain population was already against the war, and the government went in Iraq anyway. No surprise that it got booted out of office.

You can rebrand it, but you cannot claim it as your own. You must list the original authors of the code.
The above suggestions will only allow you to live maybe a few years more than the average human lifespan.
Kurzweil is looking to life extension of centuries and thousands of years, quite a difference. That's way he gets headlines.
It's different in the Windows/Linux versions.
You mean like the 300,000+ people who live on mount Vesuvio?
Does anyone remember the Hindenberg?
Hydrogen was not the cause for the Hindenberg disaster. Hydrogen burns without any visibile flame or smoeke. In the Hindenberg case, what burned was the external paint, which had a chemical composition quite similar to nitroglicerine (it wasn't known at the time).

From 12 september 2001 until bush started talking about invading Iraq.
The 358MB file you mention is only compressed text. Images and other binary files are a few gigabytes.
The main reasons a paper encyclopedia has far fewer articles than Wikipedia are manpower (you can only write so much without hiring thousands of writers) and paper costs and size (who wants a 300-volumes encyclopedia in their home?). CD-rom versions are often transcribed from the paper version or, if only digital, still suffer from limited manpower and limited availble space.

'Software' algorithms could compensate for the effects of the atmosphere. (probably by using data gather by Hubble)
No, you use Adaptive optics. Antarctica is particolarly good because the atmosphere effects are small, so the adaptive optics works very well.
What you sat is that with a heat pump you can make 4 watts of heat out of 1 watt of electricity.
Why don't you run those 4 watts into the heat pump again, hey you've got 16 watts. Now run all those into the heat pump, you have 64 watts. Repeat again....
