    Still you need to fight momentum. If you have a ship big enough to hold heavy people with heavier supplies that is a lot of momentum to fight all the time. Sure we can burst speed of multiple G's but once the fuel runs out and the ship goes at a constant speed we are down to 0g.

    My Hope if we could build a space craft that can accelerate 9.8m/s^2 (1g) for the duration of going to Mars and Back. You go to at 1g half way to mars, then you decelerate at 1g the other half. Orbit for a period of time. Drop down a landing party for a while. And go back at 1g half way decelerate at 1g the other half. Then you would have a good long range mission with out the 0g effect messing up the body.

  7. Free Speech is not Propaganda. on Former Scientologist: CoS Told Brin It Wanted Only "Good" Search Results · · Score: 2

    Nothing is perfect in the world and they are tradeoffs. If you believe that something is perfect (terrestrially speaking (I don't care to debate if God Exists or is perfect or not, today)) Then you are probably wrong.

    Everything has an up side and down side to it, whether or not the upside make it worth it or not, is open to debate. That is why we have free speech, it is so we can be allowed to look at the universe with our own objectives and try to measure if the up side or down side is worth it. However Free Speech often comes with broadcasting misinformation, outward lies, or just ignorants. In order to keep free speech working we need to keep our education levels up so we can help spot this.

    Propaganda, is sending one side of the issue and blocking debate about it. If your side is well thought out and expressed, there could be a lot less idiocracy about the topic, but it is limited and prevents growth, however this is often abused and used to spread lies as well.

    Saying you should block all sites that say something negative about your beliefs is trying to say I want you to be part of our propaganda engine. And restricting free speech.

    Now Google biggest value is in Good Will, an accounting term to express Brand Recognition and Trust. If Google were to degrade their customers trust, they will go to different sites and ruen Google.

    Calculus express the idea Optimality, and gives you the tools to help calculate it.

    For example say we have good government project that we are paying with our tax dollars, its benefit per cost ratio follows a y= log(x) type of scale. So it comes to a point where you should be informed enough to say. No we shouldn't need to put more money in this service because the cost is too great for the marginal benefits it will receive, vs getting caught up in the political feel good nonsense of, see the good that we have already done, imagine what we could do with more... You don't need to imagine you can work it out, it isn't that much better. Conversely it could mean at the current price range on that same Log scale that you should increase money as the slope at the new price point adds more value vs cost of the service.

    Even if you are not solving Calculus equations you have learned a skill to help you understand the world, and by doing those assignments in school helps you understand at least on a grand scale on how to manage things.

    The interesting thing about SETI it is one of those projects where the side effect technology is more important then their main research goal.
    Scanning Space Radio signals trying to find Extraterrestrial life is in itself rather futile goal.

    1. Radio Waves bounce off atmosphere. Sure it does get threw however most of our random singles from TV really get so bombarded by static that the waves data is nearly traceable due to the static from space. Even before we leave the solar system.

    2. Radio is only used for a short period of time. We have been using radio for about 150 years, and for long range broadcasting it is getting much slimmer. As we have built an infrastructure to send most data without radio, we use radio for short range broadcasts. So say we have about 500 years of useful radio useage. In terms of tracing a society that is like a blip. So you need to find the star, with a planet, with life, who is intelligent, has an instinct to build stuff, figured they needed radio, happen to run across similar experiments to discover it, had the engineering mindset to make something out of it, used it over the alternatives, and hasn't outgrown it. This is slim pickings. If you think about it, it was said the burning of the Library of Alexandria set mankind back 500 years. Who knows how things would be different.

    The Intel x86 (IBM and IBM Compatibles PC's which were called at the time) got market dominance. When you said PC you meant the x86 CPU. and the others were by brands.
    Laptops when they came out were very underpowered compared to their Desktop Counterparts, so they Didn't get the PC classification for a while, so a PC meant an x86 Desktop unit.
    Then as Laptops in terms of performance caught up to the Desktop, it got the PC title. As to express any x86 system able to run Windows.
    Now we have smartphone and tablet coming to the market, which have moved PC to include Non Windows running systems, including Macs. However excludes light weight systems such as tables.
