    There is a question in this funny volume that addresses this subject. I don't have the book at hand, but it goes like this: If you had the choice, and no one could ever know that you had the choice, would you allow the United States to sink into the ocean 500 years after your death in exchange for an ATM card that can remove money from any ATM without taking money from your account.


    You left out ".... and an ironclad guarantee of no retribution, prosecution, or ostracism..."
    In which case why not withdraw enough money to live well AND start building a giant dome over the USA to protect it once it starts to sink.

  3. Re:GPS on Mars Rover: Tumbleweed Models · · Score: 2, Interesting
    Would it maybe be possible to place a limited GPS system on mars? I imagine deploying just three sattlites in geosynchronous orbit over the area where the tumbleweed probe is to land.


    Question: how difficult is it to put satellites into geosynchronous (or Areosynchronous :-) ) orbit from outer space? Two problems come to mind: 1) we are good at shooting satellites up and nudging them into the right orbit, but I suspect there's a bit of a reverse-thrust required to get a satellite to "drop down" into orbit from space.
    and 2), I'm a bit ignorant of the calibration methods for GPS. Just how would the three Martian satellites get their position calibrated? Drop a retro on the planet's surface or something?

  6. Re:A computer is no washmachine, but why ? on Self-Repairing Computers · · Score: 1

    Well.... fundamentally, computers become allegedly obsolete in 3 yrs or less as much because software gets upgraded every time a new computer shows up, and the upgrades are not back-compatible. Washing machines, and cars, and AA-batteries have reached limitations imposed by various physical laws; CPUs and scanners and printers and video displays have not.
    Also, while it generally is cost-effective to repair cars, anything over very minor problems w/ washing machines, stoves, refrigerators, 35mm cameras, TVs, phones, etc. makes it far more cost-effective to buy new rather than repair.

    My guess is either geography (big mountain ranges) or the problem of distance screwing up both supply and control chains. Once it takes more than some length of time (month?) to communicate between the central hub and the outlying regions, it's next to impossible to maintain strict control.

    radiation: habitat may not be aproblem but I haven't seen refutation of the inflight problem.
    Gravity: when I typed "gravity well," that's shorthand for "it costs way too much to push people or hardware up from the ground in the first place." No solution to that, and thus no solution to major emigration.
    As to low-grav or zero-grav: there may be proposed solutions but to date IIRC no exercise program has demonstrated an ability to stop bone mass loss.

    I challenge you to come up with scientific experiments which cannot be done w/ unmanned systems. Further, I disagree w/ your "300 years from now" stuff. There is no indication whatsoever that we've missed some fundamental law of physics which would let us violate gravity, accelerate reactionlessly, etc. So in all probability neither we nor any other sentient life in the universe will be able to travel in parsec-class jumps. Ever.

    Personally, I find the same anti-space-exploration arguments being repeated for every single article discussing space-exploration to be a bit depressing and redundant with each other. "Why?" is certainly a good question, but when people ask it OVER and OVER again, while covering their ears when someone replies, that's just irritating.

    I too question the need for things like this, but I consistently come to the conclusion that exploration is still a very necessary thing for the survival of our species. Sure, we have "localized" issues that we need to give attention to, but a good planner devotes some amount of resources to long-term goals. If we constantly forget about the big picture and devote 100% of our resources to fighting short-term problems, we piss our children off (and maybe go extinct).

    I say:
    And yet nobody has (or can) refute the radiation problem or the gravity-well problem. It only helps to colonize Mars if we do so by moving 2.5 billion people OFF Earth. Sending 50 people over and letting them be fruitful and multiply doesn't solve anything.
    We've got tons of great data (aka spoils of exploration) from the Hubble scope and various planetary probes. Putting a human in deep space won't help. So about the only good reason to send a crew into space would be to lasso a wormhole or two and drag it back here (thus solving the radiation and the gravity well problems in one swell foop!).

    Our houses, cars, TVs, ovens, toasters, etc... nearly everything we use on a day-to-day basis... contain "legacy" technology.

    Our medical profession uses techniques that are centuries old. Why? Because they work.


    Well: my toaster uses a microchip instead of a bimetallic strip to set cook times. Which works better?
    TV: it's taken 20 years + to start converting to HDTV which will be miles better than "legacy" NTSC. And if we'd strictly used "legacy" color TV standards, we'd have noncompatible color/B&W broadcasts. The first fielded color system used a spinning tricolor disk.
    Automobiles almost exclusively use front-wheel drive now. So we lose the "legacy" of driveshafts and rear differentials. This was a bad thing to happen?

    Medicine: the stethescope still does wondrous things. At the same time, advances in drugs let us stop using any number of medications which had nasty side effects or mortality risks.

    Most do, but not all. Hydrogen Peroxide is often used by itself as a monopropellant rocket fuel, for instance: just run it past a platinum screen and it reacts all on its own, no air required.


    At the risk of achieving my first-ever negative mod, let me point out that "oxidizer" doesn't mean "air," and doesn't even mean oxygen. It just means something that will strip electrons from the fuel source (just like 2H +O2 --> 2H+ plus O2-- ; and sorry about no superscripts there).

    And untrue, and beside the point. Like it or not, proving that a bomb would work was fundamental to validating a pile (sorry ;-) ) of nuclear physics.

    Downfall does make it clear, however, that a US invasion of Japan would have been a disaster in terms of Allied casualties, and Japanese civilian deaths. All of Japan's remaining defenses were targeted at the exact point where the US invasion would have hit, and further, the strategy of bombing cities was to be turned to bombing railheads, which would have totally destroyed the food distribution system in Japan, likely causing the starvation of much of the population.


    A point of reference for this: I've read articles (no, not in The Inquirer) that estimate around two million German civilians died AFTER the war, due to forced relocation, starvation, and exposure. Japanese deaths after surrender: almost none, save radiation cases.
