    Nooope. You have to use at least abit of it. The smaller it is, the more effective it is. Zero doesn't qualify. So, physics says 10^-26 is like zero, mathematics say 10^-26 is > zero. Homeopathy works differently if you re a math guy or a physics guy.

    So let's treat it as a reciprocal. The efficacy of homeopathy is 1/amount used, so as the amount used goes to zero, the efficacy goes to infinity, and... beyond!
    (Well, okay, for 'beyond' you'd have to use a negative amount, but that's what happens when you get someone else to use yours, I guess?)

  3. Re:What's wrong with GLS on New Crop of LED Filament Bulbs Look Almost Exactly Like Incandescents · · Score: 5, Insightful

    I'd be surprised if LED's are ever as cheap as incandescents, a few year back I bought a bulk pack of bulbs - I paid around 35 cents/bulb, and the 100W bulbs were the same price as the 60W bulbs.

    LED's have many more components than a light bulb, and are more difficult to assemble.

    One thing to consider is total cost of ownership, and over the lifetime of an LED, you would have bought somewhere between 30 and 100 incandescent bulbs.
    Another thing to consider is that the one LED will use about 1/8 the power of those incandescents, so unless your power is free, you're now looking at 240-1000x the total operating cost for incandescents compared to LED's.
    My next-door neighbor has very little money, so back in 2009 she bought a big SUV because it was $1200, compared to $3000 for a subcompact... and then couldn't afford the gas to get to work. People are really lousy at looking at anything other than the initial purchase price.

    A third thing to consider is that as fewer people buy incandescents, the cost of maintaining tungsten-drawing machinery and other lightbulb-specific manufacturing equipment is going to rise. Vacuum tubes are hard to make well, and while we have a century of experience in doing so, silicon is dirt cheap and getting cheaper.

  7. Re:Legitimate use for 3D printing on Researchers Create World's First 3D-Printed Jet Engines · · Score: 2

    Jet engines are an awful candidate. The tolerances and material requirements to not tear themselves apart are tremendous. We're talking about turbine blades spinning at 5k-45k RPM, at temperatures of several hundred degrees, and pressures far above atmospheric, and an airstream a few hundred MPH in velocity.

    The inspection process for the individual blades, and then then for their attachment to the mount, to ensure that an imbalance doesn't destroy the engine is tremendously demanding.

    On the other hand, there is a case to be made for an aim-for-the-stars strategy. If you can build a turbine blade you can build anything. I would have thought compressor blades would be a much more likely candidate, but if they can get this to work, more power to them. And maybe 3d printing will give them options they would not otherwise have: internal bleed air cooling channels that follow the leading edge along its curvature, for instance. It's possible that given completely different design and manufacturing capabilities, they'll be able to make something that can do the same job with different tradeoffs.

  11. Re:A biological "race" condition? on Researchers Block HIV Infection In Monkeys With Artificial Protein · · Score: 1

    My understanding of HIV is that when it infects human cells, it hijacks the tRNA (iirc) so that the human cells continue producing more HIV viruses. With the article describing synthetic antibodies binding to HIV, the virus is unable to infect human cells. So this would seem like a race condition where the antibody needs to get to the HIV *before* HIV has a chance to infect a human cell. How can this happen reliably?

    Mostly through concentration: making sure there are 100x or more antibodies against HIV present than the cells HIV is targeting.
    But it's also helped by binding affinity. When a receptor and a substrate bind, it's generally reversible -- they can join or separate, and there is a measurable equilibrium between the bound and unbound states, which is a function of concentration of both receptor and substrate, and a constant that reflects how well they actually stick together. Generally, antibodies are _vastly_ better at sticking to things because they're designed to be. (Okay, the 'designed to be' is not actually true but for the purposes of this, it's an okay approximation) So if your antibody/HIV binding affinity is 100x better than the HIV/cell binding affinity, and you have 100x more antibodies than target cells, the number of viral/cell bindings is going to be much lower than the number of antibody/viral bindings.

  15. Re:the problem with how nuclear works in the USA on Safety Review Finds Yucca Mountain Nuclear Waste Site Was Technically Sound · · Score: 3

    The reason why power companies do not invest in reprocessing and consume fresh fissile material is because by federal law bans it. Remember Jimmy Carter's Non-proliferation deal? Yeah.

    From http://en.wikipedia.org/wiki/N...:

    "In October 1976,[8] concern of nuclear weapons proliferation (especially after India demonstrated nuclear weapons capabilities using reprocessing technology) led President Gerald Ford to issue a Presidential directive to indefinitely suspend the commercial reprocessing and recycling of plutonium in the U.S. On 7 April 1977, President Jimmy Carter banned the reprocessing of commercial reactor spent nuclear fuel. ...
    President Reagan lifted the ban in 1981, but did not provide the substantial subsidy that would have been necessary to start up commercial reprocessing."
    "In March 1999, the U.S. Department of Energy (DOE) reversed its policy and signed a contract with a consortium of Duke Energy, COGEMA, and Stone & Webster (DCS) to design and operate a mixed oxide (MOX) fuel fabrication facility. ... the government has yet to find a single customer, despite offers of lucrative subsidies."

    It's nothing to do with the ban on reprocessing that was only in place from 1977 to 1981, and everything to do with reprocessing being completely uneconomical. If we're going to reprocess, the government has to pay for it, as companies won't, but there are no technical or legislative barriers to doing so, as multiple other countries that are already reprocessing their waste demonstrate.

They probably even have increased secondary trade from people travelling in to get marijuana and then buying other stuff. Also, there's probably the effect of the novelty. I'm not saying there isn't a permanent increase, but it will be less if Nebraska and Oklahoma also legalise it.

    "Probably even have increased secondary trade" doesn't even begin to cover it. My wife works in ophthalmology and she has four patients who have moved to colorado just because of pot. That's likewise cited as a primary reason that housing prices have increased recently. I find it hard to believe that people would uproot their lives just for weed, but it appears to be happening.
    Colorado is making an estimated $1M/day in taxes on pot and that's probably significantly lower than the actual revenue, since because there are virtually no banks (one credit union) that'll deal with marijuana dispensaries, it's a cash-only business so the businesses could in theory only report as much business as they wish, and pocket the rest. If/when more financial institutions start dealing with them, and people feel they can use credit cards to pay for pot, the tax revenues are likely to increase.
    It's also not clear that the novelty is outweighed by the convenience. There are a lot of people who didn't use pot previously because it was just a hassle to get and there was a bit of risk involved. The people I know who are long-term smokers have stayed with their black-market dealers because they know it's safe and it's cheaper. But people who want to use it occasionally, or don't know/want to deal with black-market stuff, is apparently a huge market. They may overwhelm the local novelty effect.
