  1. Re:What if light travels at slightly less than c? on Faster-Than-Light Particle Results To Be Re-Tested · · Score: 3, Interesting

    It's an interesting idea, but quite unlikely... Remember that the speed of light is (supposedly!) an absolute, somewhat like absolute zero, and thing tend to approach it asymptotically. One can therefore tend to see where exactly the asymptote lies, and we'd quite likely notice the difference. For example, particles in the LHC travel at c - 0.0000009% and have the corresponding properties as predicted by relativity. If they were, in fact, traveling at c - 0.03% our calculations should be / are off by over 3 orders of magnitude (gamma 7500 vs 4).

    In short, that much error in c would pretty much wreck relativity anyways.

    With the caveat that I don't really have better qualifications than you :).

  2. Space elevator on MIT Working On Industrial-Scale Graphene Printing Press · · Score: 1

    If they are indeed intending to make these 1km^2 area sheets as long rolls instead of ridiculous squares, it seems to me that this has interesting implications for a space elevator. At a lenth of 35,000km, an area of 1 km^2 works out to be 2.8cm, which could then be rolled into essentially a giant nano tube. According to Wikipedia, graphene's tensile strength is 130GPa, which is incidentally precisely the estimated material strength required to build a space elevator (again, according to a quick Wiki check).

    So, it looks like if they can indeed manage this, we will be much closer to the tech required to build a space elevator. (And perhaps, in a more general sense, finally have what nanotubes have long promised.)

Realistically, though, it seems most likely they'll get spun off as their own business.

    The point is, there's more than enough room for T-Mobile or a similar company in the mobile playing field. About the only problems they have are people willing to sacrifice everything else (i.e. cost, customer service, etc) to get an iPhone or avoid that little dead spot that may or may not even exist. This is more a marketing failure than anything. Implying that T-Mobile will disappear is implying that there's not market for well priced reasonable service.

    "Please try again" is soooo classy, especially when you're wrong :/.

    First, the stock market is completely tied to the economy and follows it fairly closely. Or do you think that all the economists looking at it don't know what they're talking about? Sure, in theory, the market could go to zero. Or aliens could kill off humanity. The simple fact of the matter is that there are feedback mechanisms inherent to the market (both stock and whole) that make that basically impossible.

    More to the point, though, is that you're completely ignoring how the market actually works. A new company doesn't start selling their stock a $0, but rather some price (say $X). People buying that give money to the company in exchange for stock. The company has $X and the stockholder 'has' $X in the market. The market has grown by $X because the introduction of a new business. Who do you think created that new company but new people (in the big picture)? This is just like the economy as a whole. More people -> Bigger/more companies -> bigger market.

    The economy isn't inherently zero sum because growth in the populous leads to an increase in wealth. Basically, think that the amount of gold is constant, but the number of people wanting it grows, so its price goes up with the population (which is how we used to use gold for coins, but now that's almost unthinkable). You could buy gold one year and sell it for a profit the next. The person that bought it could then resell it the year after and also make money. Nobody lost. (This assumes, of course, its increase in value outpaces inflation and there is unbounded growth.)

    Of course, that very last bit is the sticking point. Probably the main reason we are in a recession these days (not that, of course, people can get past blaming politicians long enough to realize it) is because the enormous growth (birth rate 3.8) provided by the baby boomers pumped up the economy, which is what funded the "greatest generation". These days, the birth rate is around 2 for the US and 1.5 for Europe (where about 2.1 is replacement). A decline in the population naturally cases and rescission, but the effect is massively amplified by hedging on unbounded growth (social security, pensions, etc). In short, the market will hemorrhage for years.

    So, in summery, the economy isn't zero sum, and in the current market, the 'winners' may have only gotten about half of what was lost.

I do agree that it's a pretty weak decision.

    However, that only says that such terms are not _necessarily_ unconscionable, but still seems to leave plenty of room open for the circumstances to make them unconscionable in a specific contract with specific circumstances.

    1) A terms of service which is not provided on an individual basis (i.e. there's no discernible ability to negotiate the contract's terms)

You know there's an AP at these coordinates, but you could probably have guessed that buy looking them up and seeing there's a house there. So now they know for sure (within a few houses) and its MAC address (which, again, isn't visible on the net).

    What bothers me isn't that they know where APs are, it's why. Basically, it lets them track all the major places in your life, even if you have your GPS off, just by passively listening on WiFi bands. Home, office, friends house, etc. It even has the benefit of being able to determine this _without_ frequency analysis (like GPS) because of the availability of out of band data like SSID text and whether you have the network saved. It even works on laptops! I'm amazed that no one seems to ever raise these concerns and instead focuses on GPS and AP locations (like this law) when this is just as, if not more, invasive.

    Fission power _always_ worked. At it's most basic level you could attach a thermocouple to radium and boom, power. Hell, just put enough enriched uranium (we had known about its fission properties) in one place and BOOM for sure. The only question was the actual engineering engineering effort to design a useful plant. Fusion is different. While it has long been possible to actually make it happen, getting it to produce a useful amount of energy has not. The science just isn't (or at least hasn't been) there. Then we need engineering on top of that... It's one thing to create 2J or heat with 1J of electricity in the lab and a whole different one it converting to electricity and refining the fuel and still have a usable energy source... basically, not possible.

    So, as far as funding is concerned, the ITER, is projected to cost $25 billion. That's not really chump change for a research reactor: consider that the Shippingport reactor (first commercial fission) cost only $500 million to make, adjusted for inflation. Oh, and this one isn't expected to produce power... Their _goal_ is to produce 10x in heat what they put into making the plasma. Specifically, they aren't counting conversion to electricity, the costs of refining fuel (it's tritium/duterium) and other operation costs (coolant pumps, etc). Also, they don't yet have a design that will last long enough vs. the fusion products to be commercially viable. And the reactor core will become radioactive, too, making replacement especially fun.

    That last bit is the real take away here. They have $25 billion in funding, and they don't even know what a useful version could be made out of. That isn't a $25 billion question, that's more like a $25 million question. And it's one that needs to be answered in a big way, and yet that's not their focus. Am I to believe if they got $26 billion that the extra 4% would go to solving these vital problems? Sure their big demo reactor is fun^W^Wshould be helpful, and yeah, if they had twice the budget they probably could have finished it sooner. But what's the point? It's still not a halfway viable design for reasons completely unrelated to funding.
