  1. Tidal locking on Earth-Like Planet That Could Sustain Life Found · · Score: 1

    So, they only think it is tidally locked? Some follow-up questions.

    Earth is not tidally locked. Why? I have heard that they think this is because of a massive collision which created the moon and spun up the planet at the same time. Could this not have happened to this other planet?

    If this did NOT happen to this other planet, would that planet have a magnetic field? If it does not have a magnetic field, would it not have lost most of its water to space due to solar wind, as has happened to Venus?

    And if it has no water, this planet may be "habitable" in temperature only, with virtually no water present?

  3. From the comments below the article... on Don't Cross the LHC Stream! (Maybe) · · Score: 2, Interesting

    Someone calculated that about 4 joules of energy would be deposited. I assume that is in a single pass of the beam. However, if the beam recirculates (does it?), then the hypothetical hand will get hit by the beam many times. Then a huge amount of energy will end up in the hand in a short time and it'd probably be cut by the beam as you inserted it.

    What also intrigues me is whether a fatal does of radiation would occur from the 4 joules/pass that you would get. I think it would be about 8 Gray of radiation dose into the hand. A 5 Gray whole-body dose of radiation is usually fatal. The hand is less vulnerable to radiation than the body in general, however, this cannot be a good thing.

    Here's my take:
    multiple passes: either hand is sliced as it is inserted into the beam, or the hand explodes
    single pass: might lose the hand, owner of hand might get pretty sick

    If you RTFA, they mentioned that they're going to be using a different-than-standard electronic technology based on silicon carbide rather than silicon. Silicon carbide does not decompose until 2730C, per Wikipedia, wereas the Wiki article you mention states that "most" magma is around 1300C or less.

    What I wonder is if you make a conventional CPU out of SiC, you can operate it at a far higher clock because it won't melt itself, thus enabling high performance CPUs or perhaps 3D integration.

  12. Humans are ill-equipped to survive ANYWHERE else on Abandon Earth Or Die, Warns Hawking · · Score: 1

    Let's face it: humans are poorly adapted to live anywhere but here on earth. We don't like no/low gravity, we need a huge biosphere to support us, we need a plethora of symbiotic intestinal bacteria just to digest our food, etc., etc., etc. It's very hard to take all that stuff with us and keep it all functioning in a self-sustaining (except for energy) way. The various biosphere projects have shown how difficult it is to keep a small environment balanced. I do not think we could do it long term in a reliable way.

    If we want to go somewhere else, we have to become very different. Perhaps migrate our consciousness to a silicon-based implementation, or solid-state anyway, so we can deal with cold, radiation, and "eat" sunlight directly. Or at least bio-engineer ourselves to deal gracefully with zero or low gravity, high levels of radiation, etc., so we can live in orbital habitats, perhaps in the asteroid belt. It would be much easier to travel between the stars in such a form, too.

    In the end, I do not think that the "humans" that end up leaving Earth will much resemble us except in intelligence. I think changing ourselves to make us more portable would be much simpler than trying to re-create all that Earth provides to support our life.

    The reason that 'the best' are not going into teaching is because it rewards poorly as a career.
    The money sucks, you have to deal with people's undisciplined brats, you get blamed for kids' failures (instead of the kids and parents getting their fair share of the blame)....

    About the only benefits are job security (which is evaporating slowly) and 3 months off during summer--(which is also evaporating as schools go 'year round').

    Not only that, as a teacher you have to endure the meddling and mandates of everyone who wants to 'fix' the educational system, until you are a powerless mouthpiece for the official doctrine, and must also deliver the dogma-of-the-week in a specified manner.

    We get bad teachers in this country (USA) because we have made it a TERRIBLE job.

    Sir,

        You make an interesting point. My counterpoint is this: the effect you speak of leads to a winner-take-all society. For example, the sports players that are in the top 1% of their field collect 99% of the money to be made. Minor league baseball players make diddly squat compared to the major league players.

        This is due to the effect of mass media and a global society. Everyone watches the major leagues, because the media carries them, while the minor leagues are ignored. And the money follows the media attention.

        So there are a VERY FEW "winners" and a lot of losers who barely scratch by.

        This holds true for ALL entertainment. Many talented musicians make nothing. The top 1% of their field makes a killing.

        With large companies, this is happening too. Executives are cleaning up in companies, everyone else is getting diddly.

        This is leading, almost inevitably, to an insane stratification. Someone who outperforms YOU by 5% or even 1% gets paid 1000x what you do. The elite collect ALL the wealth. Everyone else just scratches by. Whole professions are dominated by a few superstars who collect all the money to be made, while the rest (who are almost as good, or BETTER but unknown or unlucky) languish in obscurity.

        Yes, this is a result of supply and demand, and a result of mass media and popular culture, and is an "economic" truth. THAT DOES NOT MAKE IT RIGHT OR DESIRABLE. It offends me that some idiot THUG who CAN THROW A BALL 1% better than OTHER BALL THROWERS makes hundreds of millions while the doctor who saves my life by spotting and removing a melanoma makes $200k/year working 80 hour weeks and has to spend 40 of those hours filling out BS health insurance forms. (And incidentally, by catching this melanoma early, this doctor also saves my health insurer $1M in cancer treatment bills!)

        This is pure social inequity and I have NO problem fixing this brokenness in the market via VERY progressive taxation at the high end. The capitalist free market is NOT holy, it is NOT moral, and it should serve HUMANS not the other way around!
