    I figured it was a made up name, so I didn't bother to wiki it. Thanks for the info. It still sounds more cool than it really is.

    Now, I may not be all in on the IT/Security lingo, but this seems to be over selling it a bit. Or at least giving it a much cooler name than it really is.

    All he was doing was saving a text file and then having someone else email it from an internet cafe? I think a 10 year old could come up with this simple scheme. But I guess it was simple and effective.

    >>>may be claimed as tax deductions

    My parents claimed ME and my two nieces on tax returns, and we didn't get SSNs until we were 16 (i.e. when we started working). So your claim is false.

    You're right, because nothing could have possibly changed since were a kid... Take a look at http://www.irs.gov/publications/p17/ch01.html#en_US_2010_publink1000170567 Specifically:

    Dependent's social security number. You must provide the SSN of each dependent you claim, regardless of the dependent's age. This requirement applies to all dependents (not just your children) claimed on your tax return.

    Making citizenship of the US a requirement for the contest is just stupid. I scanned briefly through their rules posted online - I couldn't really find an answer. Seems to create a lot more work for Google. Unless of course it was all a ruse to get your kids SSN... MUHAHAHHAHAHAAHA!

    You are exactly right. I suppose I was a little over reaching in my statement about the poll itself. The atrociousness of the summary should be no surprise... But, to be clear, I am not a statistician in the formal sense.

    The sample size quoted was 1019. At 95% confidence level, the simple statistical error is about 3%. That puts basically everyone from 2-9 at the same amount of admiration...

    Rabbits are actually lagomorphs, not rodents. I realize that mice are mentioned as a problem too, but the number of references to rabbits as rodents is quite offensive.

    Mike Godwin's response is a great read! Thanks for posting that.

    How exactly does a Deputy Director of the FBI not quote the law verbatim, but omit the parts which might don't support his argument? "Nothing to see here, keep moving along" I suppose.

    I especially love the tone of the letter. It walks the line of calling the Deputy Director of the FBI an idiot very well.

  11. Re:Something new? on NASA's Juno, Armored Tank Heading For Jupiter · · Score: 2, Informative

    They are still using hardened electronics, but Jupiter's radiation belts are orders of magnitude more intense than Earth's radiation belts.

    The main component to shield against in the Jovian environment are high energy electrons. It turns out that shields made out of higher charge elements are better at shielding electrons per mass. Aluminum is the defacto spacecraft material. You want something higher on the periodic chart than Al (for the best shielding to mass ratio), so they chose Titanium due to considerations like material availability and ease of manufacturing while still standing up to being launched into space.

    Another possibility for high energy electron shielding is to take aluminum and place a higher charge metal (Tantalum is often used) layer right next to it. The Aluminum is the structural component, but the Tantalum is the shielding component.

    My guess is this is exactly why they implemented this system. Students (and their parents) going to school administrators trying to get grades and degrees. Having taught a few classes and TA'd a bunch more, this is exactly why I always had a sign-in sheet.

    I think the students in the article bring up some interesting points about the possibilities of abuse and tracking of students whereabouts.

    Re:

    100s of mSv range

    There are portions of the world that have a very high natural background in the 200 mSv range so you are not quite right with your estimates. In addition, you have to distinguish between whole body dose and localized dose. It is not uncommon to see tumor doses in the 40-50 Sv range.

    The machines were set for .5 Gy (for xrays 1 Gy = 1 Sv) and got 3-4 Gy. A whole body dose of just above 4 Sv is a 50% death in 3-6 weeks (with no medical intervention). (remember that the CT was only to the brain). They are definitely in some dangerous territory, but the article said the median age of the patients was 70. Couple that with the fact that they already had a stroke and it is safe to conclude that long term effects are unlikely to matter.

    CR-39 is a very common detection method. It is by no means unusual. The article does make it seem that way, but that is not the case. It is just a passive detector and is fairly cheap. The plastic is typically etched after exposure and analysis is usually automated with some software that "reads" the tracks.

  21. This is /., no one RTFAs.... on Black Holes From the LHC Could Last For Minutes · · Score: 1
    The abstract from the preprint is here:

    In this paper we present the results of our analysis of the growth and decay of black holes possibly produced at the Large Hadron Collider, based on our previous study of black holes in the context of the warped brane-world scenario. The black hole mass accretion and decay is obtained as a function of time, and the maximum black hole mass is obtained as a function of a critical mass parameter. The latter occurs in our expression for the luminosity and is related to the size of extra-dimensional corrections to Newtonâ(TM)s law of gravitation. Based on this analysis, we argue against the possibility of catastrophic black hole growth at the LHC.

    Notice that this whole analysis is based on a warped brane-world calculation. In this calculation, it is assumed that there exists a 5th dimension in which gravity can act. We currently have no (physical) indication that there are any more dimensions than the ones we can perceive in every day life. This is really a very academic paper and subject. Unfortunately, many laymen think they are qualified to comment on the physics involved in these calculations.

    It is a harsh reminder to all physicists that we suck at PR work.

    In conclusion, I applaud you for reading the preprint and I support your statement:

    Go back to worrying about your 401Ks.

    That being said, where does the person who pirates a game to check it out and then buys it fall? I don't pirate games because I don't care that much to go through the time and hassle of torrenting a 20 Gig game. If I want it that badly I make the decision on whether or not to buy it.

    I agree with the original poster and article that there does seem to be this culture of revolution surrounding any kind of file sharing that thinks it is some making a social and political statement through theft. Hell, maybe they are since Sweden has the "Pirate Party".

  23. Actually funded by NASA? on NASA Produces Rap Video On Astrobiology · · Score: 2, Informative

    From what I can tell, the actual rap was done for the Astrobiology Magazine European Edition (AMEE). The AMEE credits the European Space Agency (ESA), the European Astrobiology Network Association (EANA) and the Astrobiology Magazine on its front cover. NASA only contributes funding to the Astrobiology Magazine as far as I can tell.

    So claiming this rap was commissioned by NASA is slightly misleading in my opinion.

    During a presidential election (typically largest voter turnout), I have averaged about 45 minutes because I try to vote before I go to work.

    It really depends on a lot of variables- how long it takes you to get to your polling place, what time of day you vote, the typical district size in your area (affects the number of possible voters), the average age of your district, etc.

    I doubt 45 minutes is non-standard, but I have lived places and voted in local elections where it has taken my only 5 minutes also.

  25. Re:I for one... on CERN Announces Collider Startup Delay · · Score: 1

    Ok.
    The acquisition of mass in the Standard Model (which only deals with the strong and electroweak forces) is through the interaction of the fields we know (ie. protons, electrons, etc.)with the Higgs field.
    Now if something has mass, according to classical gravity it has a gravitational field. But in a Quantum Field Theoretic interpretation of the Gravity (as you said, all forces are mediated by an exchanged boson) the force of gravity (that is the attractive interaction between 2 massive particles) is mediated by the exchange of a Graviton (forced to be a spin 2 particle).

    The Higgs is Spin 0 boson, and is therefore much different than the Graviton.

    My point was that many people assume that the Higgs is used in gravitational theories in some way. This is not true. (akaik- classical gravitational does not describe the acquisition of mass- I have no idea about such pseudoscience as string theory, etc. that cannot make any testable predictions in 20 years). This may seem slightly nit-picky to a casual observer- since anything with mass must interact gravitationally. The big distinction is that when people are working on describing some particle physics experiment the force of gravity is never taken into account. Now lots of people will exclaim at this, but the gravitational attraction between two electrons, for instance, is vanishingly smaller than the electromagnetic repulsion and introduces completely negligible error into the calculations.
