    um... you're using an entertaining TV show to tell you whether the science portrayed on another entertaining TV show is real?

    Don't know about mercury fulminate, but they were supposed to be using hydrofluoric acid which will dissolve glass (which is why it came/comes in plastic jugs and why WW told Jesse to put the body in a plastic barrel) and porcelain and iron/steel. I don't know if it would dissolve a body very well.

    So-called "reality TV" is just entertainment. It's all BS. There's no moonshine, no "revenooers", and nothing illegal being done. Anything that looks that way is staged.

    I worked at HP in the early 90s and HR used to brag to employees in large meetings that they had got together with HR from many other tech employers to write job descriptions and titles and define pay and benefits. I was blown away by this at that time and wondered how it could be legal.

    An interesting idea, but it seems to be the opposite case for doctors purchasing malpractice insurance. They do what they do many thousands of times with each instance being a risk for a future lawsuit. By your logic, they should not purchase malpractice insurance. I don't know what the stats are for career long comparison of cost of insurance vs cost of settling with disgruntled patients, but I'd bet it's actually cheaper to self insure. The problem is you may not be able to afford to do that until several years into practice and by then you may have already faced enough suits to bankrupt you.

    I think the real question is whether someone taking a risk can afford the cost of the worst possible outcome. If they can't, they should either find something less risky to do or buy the insurance.

  11. I think the comments are being misinterpreted. on Japanese and Swiss Watchmakers Scoff At Smartwatches · · Score: 1

    "Company representatives seemed sure that people in practice would be uninterested in constantly recharging their watches and downloading software updates just to tell time"

    They are absolutely right- no one would go to all that trouble just to tell time. But people who wear smartwatches don't use them just to tell time. Of course, calculator watches have been around for years and those haven't taken any business from Swiss watchmakers, so I can't imagine smartwatches will do so either.

    I think the Swiss are saying they're not interested in the smartwatch market, not that there won't be a market for smartwatches. I'd bet their bankers will be happy to stash the money made from smartwatches.

  12. When is HP going to have to pay up? on Apple, Google Agree To Settle Lawsuit Alleging Hiring Conspiracy · · Score: 4, Insightful

    I worked at HP in the early 90s and they used to announce to us that their HR people had sat down with HR people from many other large engineering employers (including Intel, Cisco, etc.) in the Bay Area and throughout the US to define job descriptions and pay and benefits packages. I thought it was bullshit, but most of fellow employees didn't think much of it because the next part of the announcement was the 3% annual pay raise everyone was going to get.

    If there are any lawyers out there looking to prepare a similar suit, let me know!

No, we are a long way from 3D printers becoming household items.

    The idea is good, but designing a reliable keyboard is the hardest part of the project. I don't think anyone has ever made a keyboard as reliable as the ones in the HP calculators. Maybe you can hunt down the engineer(s) who designed the HP keyboards from the 80s and get them to work on your project, if they're still alive.

    I use RealCalc on my phone and it does a good job of emulating an HP calculator. These days I rarely use the scientific or trig functions.

    I don't understand what you and JM mean by "safer" versions of the vaccines. What data do you have to support the supposed lack of safety of the vaccines?

    If you had measles and mumps and it was no big deal, you were lucky. There are many who are not so lucky. You are making the same mistake JM does- equating a single data point- your personal experience- to a generalized experience. Science/public health doesn't work that way.

    I suggest you look up the potential problems caused by measles, mumps, and the other diseases we vaccinate against before you make statements about how it is better for people to get the diseases than to be vaccinated. These will get you started:

    " I had mercury fillings in my teeth when I was younger, which I was then told was poisonous and had to be drilled out and replaced. Very pleasant."

    Whoever told you that was misinformed or lying (maybe they wanted to profit by drilling them out and replacing them). Your fillings weren't "mercury". Your fillings were mercury/silver amalgam. An amalgam is an alloy that forms when mercury reacts chemically with silver. An alloy is a stable chemical compound. It does not spontaneously decompose into its constituents. If it did, your fillings would have dissolved and disappeared long ago.

    Yes, when amalgam fillings are first placed you are exposed to some mercury vapor. That is why the ADA recommends that amalgam fillings should not be placed in small kids or pregnant women.

    Amalgam is a very durable, long lasting restorative material that has been in use for over 100 years. Amalgam restorations normally last much longer than alternative materials such as tooth colored composites which require frequent maintenance/replacement. Did they tell you about that before they drilled out all your "mercury" fillings?

    For the ADA position see latest info summarized here: http://www.ada.org/sections/pr...
    The summary on page 2 says:
    "In the six years since the LSRO report was published the identified research gaps have
    not been completely addressed. However a number of studies have added to the
    growing body of literature on the topic of amalgam safety. The findings of the studies
    published between January 1, 2004 and June 15, 2010 showed no consistent evidence
    of harm associated with dental amalgam fillings, including for infants and children. There
    is some evidence that mercury excretion may be affected by gender. There was no
    evidence demonstrating that some individuals are genetically susceptible to harmful
    effects from exposure to the low doses of mercury associated with dental amalgam
    fillings. Overall, studies continue to support the position that dental amalgam is a safe
    restorative option for both children and adults. When responding to safety concerns it is
    important to make the distinction between known and hypothetical risks. "
