  1. Re:Cast? What cast? on Solar Super-Sail Could Reach Mars in a Month · · Score: 2, Informative

    Yes, but you could anchor the corners, like we do here with a mast. Does a sailboat sail only provide momentum to the portion of the boat that is behind it? A mast erected at the stern of a sailboat still pushes the whole of the boat forward.

    Whom are you speaking of? You make it sound as if it's a Soviet style election.

  3. NASA's real issue on NASA Prepares for Space Rescues · · Score: 1

    Is not whether to have a rescue shuttle always ready. They can't. They only have three working shuttles and either dedicate one to solely rescue missions, which probably won't happen in the next 100 flights or they reduce their schedule to always piggyback missions (and leave one shuttle always at the end of a run waiting for the other two to be turned around.) Building another is pretty expensive.

    NASA's real question is: do we build another shuttle or do we go to a new generation of technology to get payloads into space? Disposable rockets still work the best as for cost efficiency, but the shuttle is oh so much sexier.

    So NASA's real question is:
    Cost-efficient or sexy?

    fI/On the other hand, IIRC, one minister tried to remove Darwin from teaching programs, but the model for this behaviour stays in US, not in the Vatican./fI

    This behavior is very scattered and would die out if such a fuss was not made about it. A smattering of rural, backwater school districts try to remove Darwin or teach it as a theory. The USA still features a considerable number of the world's finest science and engineering universities and our science funding apparatus still funds research conducted throughout the world.

    Well according to the article, ". . . The planet candidate is about 1.5 times the diameter of Jupiter and about five times as massive. . ."

    So I guess that means the disk is about 2.25 times bigger than Jupiter's. Pi are squared and all that.

  12. Re:Proper word usage on Saturn V Preservation Efforts · · Score: 1

    Okay, call me a nitpicker but here's as good a place as any to ask people to use the word properly. I'm speaking of one of the most frequently improperly used words in colloquial English, "pilgrimmage." A pilgrimmage is a religious event with roots in '. . . wandering away from your home . . .' It's not the location you go to, its the trek that makes a pilgrimmage a religious event. Since visiting the Saturn V is not about the trek, but about the object of devotion, pilgrimmage is just plain the wrong word. ((I know, the media use it in this sense all the time, but do you always emulate the mainstream media??))

  16. Re:Don't show your ignorance on Ariane 5 Deploys French Spy Satellite · · Score: 1

    You are showing your ignorance. While the American Revolution could not have succeeded without French intervention, the allies of the French were hardly a bunch of buffoons as you portray them. Rochambeau was far from the French best officer. To credit him with the victory at Yorktown is laughable. De Grasse's fleet's intervention was essential, but the British fleet he defeated was not the main British squadron in the Americas. Howe certainly did not have Washington 'almost vanquished'. Cornwallis's campaign in the Carolina's and Virginia had been too costly and achieved virtually nothing strategicly. His forces were at Yorktown to be evacuated.
    As for the current round of "Vive la France!" perhaps you should ask for your $300. Saadam Hussein poured $20 billion into France in a campaign to buy French popular opinion. That's more than $300 per French citizen, so in the spirit of equality and fraternity perhaps you should a share from your nearest French citizen.

    You can thank the Clinton administration for killing the development of a reactor which burnt down all the long half-life radioactive waste and made it short half-life waste. It is much easier to contain waste for a hundred years or even a couple of hundred than for millions. But then again, that was the 'wisdom' of Al Gore.

  19. Re:Power? on Could Nuclear Power Wean the U.S. From Oil? · · Score: 2, Informative

    One word. 'Chernobyl.'

    Your one word was a perfect example of why nuclear power had to grow up and become the best solution that it is now. Chernobyl was an ancient Soviet power plant, badly designed and very badly run. New nuclear power plants are failsafe (see the referenced slashdot discussion) and have zero chance of radiation leakage, unless you set off a nuclear weapon next to one. Then again, set a nuclear bomb off next to any power plant and you have radiation 'leakage'.

    I actually know Jim Ryan, the other Ryan you mention and have to disagree rather rabidly about him being crooked. The media did seem to delight in showing him to be incompetent but the guy was a goody two shoes in college, was just as much when I saw him in the midst of his near-death cancer treatments and showed every evidence of being the same right up thru the election.

    ...and who gets to define it?

    The 'custom software' loophole has been around for years. For basics, any software which required substantial modification or creation was seen as good for programmer's jobs and as an extra expense to business, so it was given this loophole.

    In short, Gov. Blag*&%$ is raising the cost of employing programmers in Illinois and making outsourcing much more profitable. Hope you didn't vote for the idiot.
