Carbon nanotubes are an interesting discovery, but making them in adundance is non-trivial. Forming them into useful macro structures is also not well understood, to put it mildly.
This is why I found this rather interesting. Carbon nanotubes are somewhat difficult to work with from what I gather and the ability to manipulate them in such a way as to make this yarn is a step forward.
I hate to break it to you, but there will be no space elevator, at least any time soon.
Although I added the space elevator bit mainly to ensure that it would get posted, IMHO science is built on dreams. Of course a space elevator will not be built this year, or next year, and most likely not the year after that, however it is something to dream for. Without these dreams, I fear to ask this, but what is the point?
I did not seem to find the articles that clear, are they claiming to patent a specific process for making carbon nanotubes or are they caliming to patent the nanotubes themselves, regardless of the process used to generate them? The former does not bother me, however the latter is rather troubling.
According to this, about 100 billionths a degree above absolute zero. This just turned up with a quick google and it has most likely gotten lower since then. As for refridgeration, not in the near... or distant future.
I was going to mod yet feel that I must post. Why can we not just take our nationlism, stow it and accept the fact that both NASA's mission and the ESA's mission are providing valueable contributions to mankind. Spirit and Opportunity provide a prespective that Mars Express cannot. Mars Express provides a prespective that Spirit and Opportunity cannnot. Both missions are good science!
So we're flying a large, noisy, semi-empty garage in space, and it is so under-staffed (2 people instead of 2.5 required to maintain it) that we can't even use it for scientific experiments.
Actually, in a recent issue of Nature they spoke of planning experiments to search for Lorentz violation aboard the ISS. They include a Michelson-Morley type experiment and some involving atomic clocks (?!). The experiments are being pushed by Stephan Schiller and Peter Wolf (the men who brought you OPTIS) They state they hope for this to begin around 2005. Unfortunatly, a subscription is required to view the article and it was rather light on detail, yet it shows there is indeed hope for the ISS as a science platform.
If this is soon to become a reality (a large if, see my post below), than every nation on Earth is going to want to host it. Would Equador have enough standing on the world stage to pull this off?
In the article they estimate that it would require 650 tons of material. Christ, how many kilograms have we made to date! A two year timeline is unreasonable given our current limitations. Yes, it would be nice if we did have a space elevator, however I do not see it becoming a possibility in this decade. Do we not need more expertise in manufactoring and manipulating these materials? Has anyone made any mathematical models that predict the stress etc... that an elevator would need to undergo?
I think because there is no way to engage in cannibalism without harming another person, and that if a person is willing to accept that harm his competence is in question.
Actually, regarding the Mewies case there were four others who responded to his "ad" in addition to Brandes. To quote from the BBC article
"But London-based hotel worker Dirk Moller testified that he had even got as far as being chained to the bed and marked out for butchery before changing his mind. He asked to be released and Meiwes complied."
Interesting, is China allowed to dock at the ISS? If they were allowed to can they given the orbit etc..? A quick google did not turn much up. I for one think it would be a great step in the right direction for the Chinese to be allowed to join the Americans and Russians aboard the ISS in future missions.
IANAL, but my mother is. She is a public defender. She has had to defend more than one black individual who has been charged with loitering around a convience store... while using the pay telephones outside. Certain times the authorities cannot legally do what they do, however they do it. What can you do? At the time nothing, picking a fight with a police officer in the middle of the street will win you no friends. Oftentimes it is best to do as you are told and argue later in court.
The concept of freedom of speech is only useful if it promotes freedom. For example, supporting the right of Nazi freedom of speech can only lead to the growth of a movement that wants to take your freedom away.
I do hate to nitpick in an other wise excellent post, however I have a rather large problem with this statement. I ask you, by not affording certain groups such as the KKK, Nazis, or the Communists the freedom of speech do not violate your principles?
Exactly, as others have stated O'Keefe is following the CAIB recommendations to the t. Think about it if you were in his shoes, sure a lot of geeks are rather miffed that Hubble is getting scrapped, however I believe he is freaked out about the huge PR disaster that would occur if the U.S. loses another shuttle.
Why not just cryogenically freeze yourself? Who knows, perhaps some day you will be resurrected and have your brain plopped into a nice robotic body. Bleh... I will leave it at that, I already sound enough like a crackpot for one day.
You do know that there are careers outside of academia for physicists right? Have you considered Shell or BP? Oil not your thing, well there is always the defense industry. A dove? Well, there is a place for you in communications...
As an undergrad interested in numerical analysis I sincerely thank you and am downloading Quantian now. You wouldn't by any chance know of a similar project for the PPC would you?
An english teacher of mine was fond of this question.
Do you have the internet at home?
I always wanted to burst out with something along the lines of "Yes, I have the inetrnet at my house, the whole fucking thing, it's in a shoebox under my bed".

From what I gather it is more of a hobbiest toy. Yet if you are interested in game development, word is that this is a good way to get your feet wet.
For those of you interested in finding out what it is all about, see here.
Thisis not exactly new. Atlas and Titan silos have been up for auction/sale for many years.

Actually, I thought that O'Keefe stated that service mission 4 was cancelled due to safety concerns.
Look no further thjanhere to see why differential equations are quite important.
Here is another text covering the basics of special relativity, it is decent for those with a passing interest in the subject IMHO.

Just out of curiousity how bad is bluetooth security? From what I have gathered it is more or less a joke.

As I have misspelled internet, one can guess that it was not my favorite class. Heh... oops.
