This has to go before the judge, etc., so it hasn't actually happened yet. No word as to whether or not ARIN will contest it (as IP addresses are not supposed to be property; they are assigned by ARIN, which reserves rights to take them back) or, if it does, whether or not the judge would pay attention.
I am sorry, but I don't buy this, and have not bought this since I first heard it, at least as the complete story. Nobody could hot wire this ? Different generators could not be found ? Different plugs could not be found or made, anywhere on the planet ? The only solution is to bring in a 1 km + extension cord from the grid a week later?
There is something here that we are not being told. We'll find it out, and it will probably be pretty embarrassing for someone, in 6 months to a year or so.
I think what they are really worried about are very high energy cosmic rays, can be protons, but also can be atomic nuclei (I believe that Iron nuclei have been detected in UHECR's, for example). If these hit shielding, they will cause a shower of secondaries that would be quite dangerous (on the Earth, this happens many km up, so it's not dangerous here on the ground). It might be possible to use multiple shield with a gap, but that make for a big structure. Deflecting these away from the spacecraft would be a good idea, if it can be done.
We had a nuclear rocket, NERVA. It worked quite well, had a number of successful ground tests with no failures IIRC, and was ready for a flight test. It was killed for political reasons in 1972 during the Nixon administration, along with Apollo and all Apollo follow-ons.
At the Target NEO meeting, "thermal nuclear" was one of the propulsion types on the table. It's only been
By the way, "primordial" asteroids contain water, and one of the ideas we discussed at lunch at that meeting was to stick down a pipe to get water to fill those shielding tanks, which would really cut down on the lift required. This would make a very interesting target for a NEO mission.
It's only been 39 frakking years since NERVA was canceled.
I think you mean, the American literature. AFAIK, the Russian literature never used REMs at all, and some of it is in Becqurels and Curies.
When the Soviet's opened up about Chernobyl they published readings in (IIRC) Becquerels or Becquerels/m^3, causing intense puzzlement in the Western press as to how to interpret what they were saying.
The peak announced radiation at the plant gate is about 10 milli Sieverts / hour, or 1 REM per hour. If that level were maintained, an exposed person would start to get radiation sickness in a day or two.
This chart applies only to "prompt" doses. Most of the casualties from Chernobyl (4000 to 8000 fatalities and counting) were from Thyroid cancer caused by exposure of children to radioactive Iodine. This is not just a dose effect, as the same dosage from another material, or of adults rather than children, won't cause these cancers. So, this chart is not appropriate for these long-term dangers.
I am curious about your take on quantum computers. My impression is that, if they are ever actually made into an operational product, they are likely to have a profound impact in certain areas (watch out, public key encryption!), but are unlikely to be much use in sending emails or watching videos.
Here is a news flash. I have it on good authority that
- eventually Moore's law will fail, and
- the world will continue to roll through the void. Life will go on, and we will not burn our Mac Book Pro's for heat, nor turn our rack-mounted servers into crude dwellings.
No, the possibilities are not endless. They had a training film, produced by a contractor. (I don't remember which one, and I can't find a link, but it was one of the usual suspects.) That is the way the Government generally does training. I don't know how explicit the film was, but the discussion was very explicit (I remember the phrase "lift and separate," among others).
I was also told that there was general unhappiness about this new procedure, under the assumption that agents would catch even more hell from the public.
The training that the TSA agents took does require this "groping." (I have talked to off-duty TSA agents about this.) However, I also travel a lot, I always refuse the scanning, and I have yet to be groped. I think that they are just not (by and large) following their training in this matter.
Indeed, even the highest readings listed on some of the records — the numbers that the TSA says were mistakes — appear to be many times less than what the agency says a person absorbs through one day of natural background radiation.
That is irrelevant, and in my recommendation whoever came up with that formulation should be fired, or at least reassigned to duties far from any actual responsibilities.
The Commentary states that general-use systems should adhere to an effective dose of 0.1 microsievert (Sv) (0.01 millirem) or less per scan, and can be used mostly without regard to the number of individuals scanned or the number of scans per individual in a year. An effective dose of 0.1 Sv (0.01 mrem) per scan would allow 2,500 scans of an individual annually [i.e., if each scan required 0.1 Sv (0.01 mrem)] without exceeding the administrative control of 0.25 mSv (25 mrem) to a member of the general public for a single source or set of sources under one control. Assuming 250 workdays per year, this would correspond to an average of 10 scans each day, a frequency that is unlikely to be encountered.
So, if the actual dose is 10 times that, or 1 micro Sv / scan, then the "administrative control" of 250 microSv / year would require only 250 scans, or one per workday, a frequency which would not be "unlikely to be encountered." In fact, both really frequent flyers and airline crew would be likely to match or exceed this. To be blunt about it, the TSA chose words intended to obscure the likelihood that their radiation guidelines are being violated, at least for some members of the public. This does not inspire confidence.
Remember, too, that this technology was pushed heavily by Michael Chertoff when he was in office, and now he is profiting from its deployment. That also does not inspire confidence.
I think that there should be an independent audit of the TSA's use of X-Ray backscatter and that until that is done members of the flying public should refuse to take those scans. It is better to get groped than to get cancer.
Yes, but this mathematics is really more like the equivalent of mathematical physicists playing with Legos. They are not trying to fix anything, they are postulating wild and crazy stuff and asking, what can we make of it ?

If you believe this, you qualify for a job at the Libyan Ministry of Information ! I hear they pay well !

Oh, that's easy. I predict (for the East Coast of the US in Spring, 2012) periods of rain, followed by days with sunshine.
Correct

It's 100 rems.
For extra credit, estimate it in Becquerels.

Radioactive iodine has been found in milk and spinach near Fukushima, ad it is very worrying that the Japanese government is only talking about "immediate effects" when the real danger is long term.

Those "two young entrepreneurs from New York" were just embarrassed that they had forgotten to bring (or make) any cards.
I bet their business plan is full of holes. Forget small things, forget big things...

I have been unable to find any actual numbers for dosage recorded in this case, so let's look at the National Council on Radiation Protection Commentary No. 16 - Screening of Humans for Security Purposes Using Ionizing Radiation Scanning Systems, which I believe governs this.
The Commentary states that general-use systems should adhere to an effective dose of 0.1 microsievert (Sv) (0.01 millirem) or less per scan, and can be used mostly without regard to the number of individuals scanned or the number of scans per individual in a year.

Just saying...
Of course this is about politics (where, exactly, in the USA are "children are being indoctrinated in socialism via some curriculum" ?
State Sen. Mark Madsen is trying to blow the dog whistle that Obama = Socialism, nothing more, nothing less.
But the United States is a union of independent states.
Not since 1865 (well, arguably not since the beginning, but it became clear in 1865).
In a representative democracy majority rules all at all times.
Yes, a majority of the representatives which is, uh, what we have here (with checks and balances, etc.)
Yes, but this mathematics is really more like the equivalent of mathematical physicists playing with Legos. They are not trying to fix anything, they are postulating wild and crazy stuff and asking, what can we make of it ?
I get to work on it right away, if you'll pay my attorney fees !
This work has nothing to do with dark matter or dark energy (at least, as far as we know).
The model may be broken, but pursuing unusual solutions of the field equations assuming materials with unusual properties is not evidence for it.
