    It may not be stolen, it may be counterfeit. This is a serious problem with cell phone batteries. Lithium batteries can catch on fire or explode if they are not manufactured properly, physically damaged, or improperly charged.

    I don't think the Chandrasekhar limit has anything to do with gravity overcoming the forces of thermal energy. According to the wikipedia article, it's the amount of mass required to overcome electron degeneracy pressure, producing a neutron star or a black hole.

    A 7-segment display needs a 7-segment decoder to drive the appropriate segments for each digit. That's a fair bit of extra circuitry and expense when your logic circuits are built from discrete components.

    Some older equipment used displays that were like miniature slide projectors. Each digit had a small rear projection screen. Behind that screen was an assembly of miniature light bulbs and optical slides. When one of the light bulbs was turned on, its light passed through an optical slide that had an image of the desired digit. It produced a very readable display, better than Nixies or 7-segments. This display was designed and manufactured by Industrial Electronic Engineers, Inc. starting back in the late 1950s, and amazingly enough is still alive and in the display business.

    Shouldn't the voltage regulators on the motherboard offer protection from circumstances like this?

    That isn't their job. They convert power from the power supply to local power sources that meet whatever special needs (CPU power, etc.) the motherboard has.

    The main power supply is supposed to shutdown all outputs if any output is out of spec. Some chips will destroy themselves if one of their supply voltages is missing.

    Many people have older systems that can't accept more memory or use memory technology that is still expensive. It would cost me $420 to upgrade from 512 MB to 1 GB of RAM.

    From talking to people who work in the banking industry, security seems to be strictly based on cost-benefit ratio. For the bank, it is often cheaper to skip security checks. Everything is automated and they rely on the customer to detect and report any problems. They will happily accept and pay out on forged checks that wouldn't fool a five-year-old.

    They don't have to be expensive. They should be very cheap if manufactured in large quantities. I can buy a solar LCD calculator for $1 at Wally World.

    The studies that I've seen cited on legibility and readability seem to be inconsistent. One interesting argument is that the differences can be explained by the environment. Readability increases with exposure. Helvetica used to be new and different, now it's commonplace.

    Core memory has a cycle time (read-modify-write) on the order of one microsecond. Flash memory has a faster access time, but does not provide the same write functionality as core. It isn't usable as general purpose non-volatile RAM.

    We go through this crap every time NASA launches something with an RTG (radioisotope thermoelectric generator). The lunatic fringe of the environmental movement starts whining about how plutonium is the most deadly substance known to man (bullshit), and how a launch accident could rain radioactive death on the planet (more bullshit).

    Can you take your computer, power it off, stick it in the closet for a week, take it back out, plug it back in, turn it on, and have it instantly running the same software that was loaded in it when it was shutdown?

    Core memory disappeared because of cost and density issues, not because it was inferior technology. It was the appropriate choice when the AP-101 was designed.

    Why not add a little hardware and check for a living finger? When I was in the hospital, they put a noninvasive sensor on my finger that measured my pulse and blood oxygen level. It uses two frequencies of light to measure oxygenated haemoglobin.

    It isn't that dangerous. The tube contains a very small amount (2-10 mg) of mercury. Don't snort the contents of the tube and you will be OK.

    In another 10 years, I expect that they will call out the HAZMAT team for any reported spills of dihydrogen monoxide. They are already starting to treat lead like it was some horribly toxic material.

    Not according to Kubrick.
    For nitpickers, there may still be a few problems -- Full Metal Jacket, The Shining, and Eyes Wide Shut (a new addition) are still open-matte full-frame, but this is entirely in accordance with Kubrick's wishes, as he was never a fan of widescreen and thought these films looked best on TV in this manner (indeed, Spartacus and 2001 were Kubrick's only widescreen films, and it seems the director, a photojournalist in his youth, never lost his fondness for 4:3 composition).

    Widescreen is often produced by shooting in 4:3 aspect ratio and cropping off the top and bottom of the frame to get a 16:9 aspect ratio. I've noticed this on many DVDs. The fullscreen version actually shows more of the original negative.

    You are going to lose your "normal channels" because the FCC has determined that it is in the public interest to replace analog television (NTSC) with digital television (ATSC). If you receive your television signals over-the-air, you will have to buy an ATSC receiver to continue watching television. It will happen. The only question is the exact timing of the shutdown of analog television.
