What if it falls? The majority, the long end out in space, gains enough speed that it burns up in the atmosphere, with the lower portion falling into the sea. It will not fall on top of anyone.
For the portion that doesn't burn up in a fall- what effect will it have on the environment? Honestly, it will make a little bit of a mess. But New York City tickertape parades have made bigger messes. Comparatively it will put much less dust, dirt, debris and chemicals into the environment than wildfires of the American west, any one of the large expendable rockets, or a month of natural meteors hitting Earth. The ribbon is light (7.5 kg/km) so, any pieces that fall to earth will slow down, in the air, to about the same terminal velocity as that of an open newspaper page falling. It will not have enough momentum to cause mechanical damage when it comes down. We have considered other health risks such as inhalation of very small fragments and believe this will not be a problem but we are conducting studies to make sure this isn't a problem. Since we are aware of the possible problems now we can design the elevator to avoid these problems.
How large a wave/disturbance would it generate? The wave/disturbance would be nonexistent. As above, there just isn't enough mass, even in later, larger, ribbons, to generate such energy dispersion. There might be a small amount of light as a line in the sky as the ribbon burns up but after that it will be a few pieces of black film fluttering to Earth. Because of the size, distribution and winds, it is conceivable that only a few people would even see the event in any way and just as few would find actual pieces of the ribbon.
How much warning would there be from the time of a break and the time it would take for the lower portion to splash down? Depending on exactly what happened it could be a few hours to weeks.
What would happen to the surviving portion? The ribbon that fell to Earth could be recovered for study but because of the amount and distribution it would be difficult to find many pieces. The pieces that do land would eventually degrade but not for a very long time. Keep in mind that this is mostly a stable form of carbon; it doesn't do anything. The debris would resemble long hair and would probably be broken up in interactions with animals, plants, wind, fish and waves. In fiber form it would be much too large to inhale and would probably works it way through a digestive system unaffected. The only debris we have any concern about is if it were reduced to nanotube size. This we don't understand yet so we will study this to see if there is a problem and then probably also design the ribbon to remain in larger pieces if it re-enters.
If it open-sourced then I can simply modify the code to remove the license. The fact that a license could exist in open source software seems to be a conflict of interest.
Its funny how the truly stupid are the ones that like to jump all over another's errors. Its as if they are so convinced of their inferiority that they are always looking for another to err. In doing so they correct the mundane. Its good to have these mundane people around so that the brainpower of the intelligent doesn't have to be wasted on such menial tasks. Thanks!
The Leonid meteor shower was a great way for me to introduce my 6 and 3 yr old to astronomy. It was a night I will remember forever, as they will too hopefully. They still talk about the "stars falling from the sky".
My kids are actually really excited about this event. There is nothing betting then getting kids into science then direct experience.
There are still hardware companies out there that put their drivers on 3.5" floppies. I am sure 3.5" will fade out but they are still needed on the rare occasion.
The real winner will be the engineer that develops a practical system to counter-act such a device. A small device such as a watch that can detect the signal and then send a destructive wave to cancel the signal would be good.
I have never heard of this Linux news site before for some reason. Now, seeing the site, it looks like a useful site that I would have visited daily. I wonder how many sites like this crumble do to lack of knowledge of their existence. Advertise!
Everything sounds on-par for a taco salad. All but French dressing?? Where did this come from? How bout guacamole and sour-cream? French dressing really sounds odd.

Actually if you read the specs of a system such as MaxiVision48 (running at 48fps) the resolution is 528 megapixels per second. I seriously doubt if anyone is seing pixels in the theater.
This article is a case of over-analyzing a movie made for kids. I took my 3 and 7 yr old sons and they loved it. My 7 yr old especially enjoyed it having watched 4-6 many times growing up.
Growing up during the intial star wars phenom I also had desires to see attack of the clones. For 2 and a half hours I was entertained. Thats good enough for me. I wasn't expecting a cerebral experience just some good fun.
Don't link to small web servers. Make those who really are interested have to search for the site. That way the site will have at least a chance of staying up.
This makes sense given the fact that the combination of all colors results in white light. You would think that something as large as the universe would have an almost equal distribution of the different wavelengths of visable light. The beigeness could be a result in the shift of wavelength related to the universe expanding(everything moving away from us).

I didn't want to do this but its very annoying arguing with non-chemists about chemistry.
People with hypertension are often advised to avoid MSG and other sources of sodium. However, there is no evidence that sodium from MSG, or sources other than salt raises BP or contributes to the development of HTN. Indeed, sodium as salt (NaCl) has been shown to be far more toxic to the body than sodium without the chloride such as MSG, sodium bicarbonate or sodium citrate. In animals the acute lethal dose of MSG that kills 50% (LD 50) of rats and mice (15,000+mg/kg b.wt.) is more than 10 times higher than that of salt. [17] Clearly then research in animals proves that MSG is far less toxic to the body than salt.
The recent DASH-Sodium trial when coupled with other research has demonstrated beyond a reasonable doubt that Americans should be consuming far less than 1500 mg of sodium daily to reduce problems with high blood pressure.[18] This study showed that an increase in dietary sodium from salt from 1500mg to 2400mg resulted in a significant increase in blood pressure in both normotensive and hypertensive subjects. By contrast, the consumption of up to 120g of MSG (about 18,000mg of sodium) for an extended period of time did not increase blood pressure at all. In fact, this extremely large amount of sodium from MSG resulted in a slight drop in both blood pressure and blood sugar levels and produced no detectable changes in neurological function. [19] Research has shown that when the same amount of sodium is fed as compounds other than salt (i.e. sodium citrate, sodium bicarbonate and MSG) there is no significant increase in blood pressure as occurs with a similar amount of sodium from salt.[20] [21]
A teaspoon of salt has more than four times the sodium content as teaspoon of MSG (2,150 Vs 492mg, respectively). If food that is normally prepared with MSG is prepared without it the flavor and sensory pleasure associated with its consumption will be reduced. To compensate for this loss of flavor enhancement most chefs and food manufacturers would likely compensate for the loss of MSG by the addition of more salt or salt-rich ingredients such as soy sauce. By contrast, if MSG were used in place of salt in the preparation of soups, salad dressings, sauces, French fries, chips, etc. then the amount of salt and sodium these foods contain would be reduced by over 75%. Food manufacturers could use a combination of MSG and monopotassium glutamate in many foods in place of most of the salt and drastically reduce the salt (and sodium) content of many food items.
Umm..have you lost your mind? Sodium can not exist in the elemental state naturally. Of course there are thousands of compounds made of Na. Unless you are speaking from the point of view as a person that ingests large quantities of Sodium from another source, I don't think you have a point.
Here on earth NaCl is the major source of Sodium that leads to a imbalance in the sodium potassium pump.
I don't know, maybe your doing shots of sodium hydroxide! If so, you don't have long to live...
Unfortunatly you don't seem to understand that it is not only Sodium the causes hypertension. I understand that from a laymans point of view that is a good explanation. Maybe this is your point?
Really the cause of hypertension, as a function of environmental chemicals, is an inbalance in the sodium potassium pump. Sodium can play a role in this system being imbalanced, but more importently, several factors contribute to hypertension(chemically speaking).
If we want to speak in fantasy, in which pure Sodium can be ingested in a natural environment, then hypertention plays no role. If you could eat pure Sodium, you die. If you eat lots of NaCl and your body is low in potassium, you will die over a period of time.
The reason sodium is talked about is because it is used in excess. After all, if potassium was put in a shaker we would hear about potassium leading to hypertension. There is nothing special about Sodium in causing hypertension. The problem that effects our body is the balance of ion exchange.
That being said, an atmosphere, no matter where in the universe, will never contain pure Sodium(if it did then you would wish hypertension was a side effect).

Last sentence should read:

Really I dont even understand what I wrote above. Very odd.

Well I was simply saying that maybe if that had advertised maybe more people like me would have visited the site and found it useful, hence the irony.

$300 for a atx case seems to be overly priced. I wouldn't pay more then $50 for a case. Just don't sit on it!
moore is never wrong

You have a very strange diet if you are getting Sodium into your diet, in any significance, from compounds other then salt.
There are many good nutrition guides out there. I recommend Eating for Dummies.
You should visit your doctor as well. Tell him your feelings on Sodium consumption. Most likely (hopefully)he'll recommend a good psychiatrist.
