  1. Units, SI, weightless on ISS May Have A Leak · · Score: 1

    mm of mercury, I thought inches of mercury was a more commonly used unit.

    Anyway, does anybody see the irony of measuring air pressure in a weightless environment in how high (in mm) the pressure would push mercury into a tube that has the top sealed off from the air.

    I really hate it when a single article uses 4 units (mercury, mm, pounds, inch) to express pressure (force per area).
    - Mercury has the same mass everywhere, but it doesn't weigh the same everywhere, especially on the ISS where it weights practically nothing.
    - mm, wow a standard unit, I'm impressed, but it was used in combination with mercury, while normally inches are used in combination with mercury.
    - Pounds, what pounds, deprecated unit, and again it's a measure of weight.
    - Inch, again a deprecated unit, but at least it's used to measure an area, not the height of mercury.

    1 atm (standardized sea level pressure)
    = 1.01325 Bar
    = 1013.25 mBar
    = 1013.25 hPa
    = 101325 Pa
    = 101325 N/m2
    = (approx) 29.92 inches of mercury
    = 759.968 mm of mercury
    = (approx) 14.7 pounds per square inch

    Good on you Rudolph, at least one of the forgeries that

  5. Re:Why is this About US Opposing French Site ? on Giant International Fusion Reactor Draws Nearer · · Score: 1

    > The last time we even came close to "supporting" Saddam was while Iran and Iraq were at war.

    You mean the US supported one side of a war, that was none of their business. In doing so they helped Saddam become the cruel dictator everybody knows today.
    To 'rectify' the situation the US fought two more wars to get rid of him.

    Can you imagine where all that arab hatred against the US comes from? I can.

  6. Re:What they don't explain.... on "Budget" Chips go Head-to-Head · · Score: 1

    And how do you explain that I have a AMD 486-DX4-100 still running a firewall, a K6-233 still running a fileserver, and a Duron-800 that is still used as my daily workstation. Sounds to me you've had a streak of bad luck or you're combining those AMD procs with some really crappy MB's.

    If somebody asks me for advise for a budget computer, I answer Athlon 2500+ (Barton core) with a decent MB and decent memory.

    If somebody asks me for advise on a high perfomance computer, the answer is exactly the same. Why pay 3 to 5 times more for only 25% extra performance!

    > Electric cars are also at least as polluting as any other fuel, because the

    Car engines have really lousy efficiency compared to power plants. If a car engines runs at anything not close to full throttle, it's even less efficient. If the car engines runs at an rpm not close to the maximum torque, it's even less efficient. But if you choose to ignore that, you're absolutely right.

    > The greater the mass of the battery, so the more energy is required to

    Well I'll just quote you to show that this is a non-statement:
    "Regenerative braking is standard now - so the energy you expended while accelerating can be recovered when you slow down"

    The instructian set is extremely poor and a complete mess. But it's not really holding back modern processors. It doesn't matter anymore that the instructions are arcane, the processor translates them into simple instructions, and executes those simple instructions very fast.

    Looks like the specs are a bit messed up. 8.3" x 8.3" x 3.1" (21cm x 21 cm x 7.9cm) is about about 0.9 gallon (3.5 liters). And this huge volume is supposed to weight only 2.2 ounces (60/70 grams or so, depending on the kind of ounce).

    Some other sources state the same dimensions, but a very different weight. http://www.aaaprice.com/saypmp3pl.html for example claims this portable weights in at a wopping 9 lbs. I tried, but I can't seem to find the correct weight.
