    no that's exactly what it means a plasma or incandescent bulb with a blackbody color temperature has to be at least at the color temperature average physically; now you have to remember that temperature is a statistical phenomena so a plasma with a color temperature of 6000K is going to have some atoms much hotter and more atoms much cooler but the average is going to be 6000K. Certain materials have an electronic configuration that are more likely to be at a particular temperature and emit photons at the corresponding energies than at other temperatures; by mixing differing materials you can select emissions at certain peaks, then by adjusting the pressures in the plasma get the peaks to smooth into a smooth spectra.

    you'd want to let the bulb cool off before you touched it at 800-900 C you could barely see a dull red glow if your eye are sharp, but that's not a lot more than halogen bulbs, several that we use at work are air cooled such as a 50 watt hand-held curing light

    in a plasma light bulb high pressure means something between, "not very good vacuum" to "almost air pressure when warmed up"; the bean sized bulb would be more likely to implode than explode.

    Many lights in your home run at comparable temperatures, and I've used incandescent lights that were 5500K, warm-white halogen run 3000K, cool-white run arround 4100K and daylight fluorescent bulbs run from 5000 to 6500K; your confusing temperature with heat, you want high temperature with little heat.

    That's because most of us in society don't think like predators anymore; a predators wants to be unseen, and for it's potential prey to be obviously visible. a bungler would want to approach a building in shadow, to a point shielded from view, but has enough illumination to work in.

    Most email clients allow a sender to designate a reply-to address that is different than the "from" address.

The clue-less idiots who sent the original Email and didn't want to hear the whiny sniveling replies from the Morons, thought that the Morons would notice that the reply to address was to donotreply.com and not hit the send buttons.

    but how about this

    Dear Sir or Madam;
    Your organization has been sending numerous email messages of a commercial nature to our organization in apparent error.
    Many of these documents appear to contain sensitive or confidential information and this consumes valuable resources on our part to process these messages in a confidential manner.
    Several Federal laws and regulations require level of client professional confidentiality such as SEC regulations and HIPPA.
    Several Federal laws prohibit transmission of unsolicited commercial Emails such as the Junk Fax Act and the CAN-SPAM act, and allow for monetary compensation to injured parties.

    Please enclose a check for $5,000.00 to cover our expenses and to insure we have sufficient resources to remove these messages in a confidential manner, and promise to not seek relief through litigation for messages received to date. If we do not receive your check within 90 days we will assume that these messages were sent to our organization as a gift and will do with them as we see fit.

    In the future, you'll may find it more economical to study a document known as Request for Comments: 2606, Reserved Top Level DNS Names published by the Network Working Group if the Internet Engineering Task Force, RFC2006 recommends using the domain names invalid.com, or localhost. Using these domain names will keep your emails from being routed on the internet.
    regards; Budgenator@example.com


    Now you are offering them valuable consideration in return for their money and are not committing extortion or blackmail, just make sure it's vetted by your lawyer and enjoy.

    The ADA will lie to their graves about Mercury's toxicities in the body from the mouth and lungs the lungs. HCL acid, AKA "stomach acid", does a great job of dissolving swallowed Mercury fillings and their residues readily dispersing the Mercury into the bloodstream.
    Yeah that's because the ADA hates dentists and dental assistants so much, after all they are the guys and gals that used to place the damned stuff 8 hours a day. Don't worry about mercury from CFL's , we used to buy mercury by the pound and went through 2 pound's a year and 2/3 of each spill went in the trash so that means each dental office put about 120,000 CFL's worth of mercury into the landfill each year. But what really kills the environment is the amalgam that get's sucked up by the evac system, that goes into the drain and the sewage treatment plant where it comes out in the sludge which is usually incinerated; that means highly dangerous organic mercury compounds are produced and sent up the smoke stack. The last part was for us the prefect excuse finally stop using amalgam, why pay 20,000.00 for a treatment unit so we can place an inferior material, get paid less for using it? Patients don't like it because it costs more, the insurance don't like because they have to pay more for composites.

    look at this question

    How likely do you think it is that the federal government has opened mail or monitored telephone conversations of people in the U.S. without first getting permission from a federal judge? Is it very likely, somewhat likely, somewhat unlikely or very unlikely that the federal government has done these things without permission from a judge?

    I would split that question, personally opening postal mail should require a much higher standard of reasonableness and always a search warrant, listening to or reading a transcript of a phone conversation or a recorded phone conversation slightly less but should also require a warrant. Recording a conversation without listening or reading a transcript, that's an odd bird.
