  1. There's an obvious solution on Journal of Cosmology Contributor Sues NASA To Investigate Mars "Donut" · · Score: 1

    Agency management do look at how many publications cite the project when considering further funding. Allowing competing projects to beat us to publication using our own data and not our analysis is seen as detrimental to continued operations.

    The obvious solution is, look at how many publications cite papers that used the data you gathered; not how many publications cite your project. That would be a meritocracy where the projects that gather the most valuable data are guaranteed to enjoy continued operations -- and there'd be no need to restrict access to said data.

  2. The donut has already been examined enough for NASA to think it's boring

    Really? Dr. Squyres says the rock has a "strange composition, different from anything we have seen before... We are still working this out. We are making measurements right now. This is an ongoing story of discovery."

    He doesn't sound bored.

    humanity was born in the ice ages of the Pleistocene we've never experienced a planet as warm as the dinosaurs... Humans will survive a warmer earth I have no doubt, but the potential for massive disruption to the food supply is there and if that happens there's going to be some really ugly war that humanity might not survive. The reason to be scared of global warming is because of those changing fertile zones, humanity goes batshit crazy when starvation is eminent.

    Humanity has experienced the whole gamut of climates, from hot deserts to frozen Arctic lands. Civilization is very tenuous at those northern fringes (see the Vikings who ended up having to abandon their colonies in Greenland and Newfoundland).

    Guess you haven't thought about the fact that there are vast tracts of land in northern Canada, Alaska, and Siberia that will become viable farmland if the growing season gets a little longer. If the predictions of global warming alarmists come to pass (and so far they have not), I'll be concerned about inundation of coastal cities; but given the large net increase in viable farmland, there should be no concerns about starvation. Global warming is much more likely to exacerbate the obesity epidemic.

    If the data weren't acquired 100% at taxpayer expense, let the owners of the data sit and ruminate on it for as long as they please. But that's not the case, so there's not much justification for no timely release of the data to the taxpayers who paid for it.

    How would releasing this data to the public, through existing channels that have already conveyed thousands of photos to the public, be a waste of NASA's time?

    NASA has already acknowledged that this is "a very special rock, with rare properties." Therefore, shouldn't it, at a matter of course, release more data about this rock than it releases about the average Mars rock?

  8. The undersides of rocks... on Journal of Cosmology Contributor Sues NASA To Investigate Mars "Donut" · · Score: 3, Insightful

    Dr. Squyres says that if this object has been recently flipped over, "we are seeing the surface, the underside of a rock, that hasn't seen the Martian atmosphere for perhaps billions of years."

    Trouble is, unless he's proposing that the underside of this rock was somehow vacuum-sealed against atmospheric influence, it has very much been exposed to the gases of the Martian atmosphere.

    The undersides of rocks experience a different environment due to less exposure to wind erosion and the UV component of sunlight. But as far as being exposed to the gases that make up the atmosphere, the undersides are about as exposed at the topsides.

    Most if not all of the minerals observed on Mars have been seen before, on Earth. Can you think of a terrestrial example of a rock whose underside has a significantly different chemical composition than its topside? I can't.

    Rising real estate prices are good for every homeowner -- even these who don't realize it.

    I'd love it if the price of my house rose 1000%. If increased property taxes are a hardship for anyone, they can simply take out a reverse mortgage, and use a small fraction of their increased property value to pay the higher taxes. They will still be far ahead of the game, compared to a scenario where their property value remained flat.

    If you think rising real estate prices are bad, conversely you should think falling real estate prices are good. Nope... we tried that in 2008; it was called the Great Recession.

    Renters are a somewhat different story. People who can't afford to rent in chic and tony neighborhoods don't rent in chic and tony neighborhoods. What if the neighborhood around them is transformed into a chic and tony neighborhood while they're living there? They might have to move to a neighborhood that's not chic and tony. Other than the inconvenience of moving, they're no worse off than before. Nowhere is it written that renters who start out unable to afford chic and tony neighborhoods have a right to stay in their neighborhood after it becomes chic and tony -- especially because enforcing such a rule would prevent all neighborhoods, everywhere, from improving.

    If you start taxing people on the basis of things they're not doing

    That's the exact logic Chief Justice John Roberts used to rule that Obamacare was constitutional: he said that not buying health insurance is a taxable activity, and the courts can't interfere with Congress' power to tax.

    The tax that's assessed if you choose not to buy health insurance will be collected by the IRS. Before the issue went to the Supreme Court, the president insisted this was a fine, not a tax, telling George Stephanopoulus, "I absolutely reject the notion" that it's a tax. But when its constitutionality depended on it being a tax, he suddenly no longer objected to calling it a tax. And then a few short months after the Supreme Court decision, the sheeple forgot what its constitutionality depended on, and the White House reverted to calling it a "fine" again.

  14. NASA says Mars' wind can't move rocks on More Details About Mars Mystery Rock · · Score: 5, Informative

    The wind on Mars is not "strong" enough to move rocks on the surface. Even though winds on Mars can probably reach large speeds, the atmospheric density is so low, that the force the wind can impose on a rock is quite small. For instance, a wind of 10 meters per second (about 20 miles per hour) here on Earth produces a force which is four times stronger than does a 50 meter per second wind (a bit more than 100 miles per hour) on the surface of Mars. So, since a 20 mile per hour wind here on Earth does not generally move rocks about on the surface (though it does raise dust), the winds on Mars don't move rocks on the surface either.

    The historical record shows that automation always creates more jobs than it destroys: there are currently more humans employed than at any other time in history. Most of them are employed in fields that didn't exist before certain enabling technologies were invented.

    I didn't offer up inefficiency as a solution.

    You complained that more-efficient processes were destroying jobs. I can only conclude that you believe less-efficient processes would create jobs.

    But please learn a thing or two from the historical record. It shows that back when things were done inefficiently -- for example, the locomotives of 1860 converted the chemical energy in coal into mechanical energy with 1% efficiency -- far fewer jobs existed than exist today. The more powerful a technology is, the more disruptive it is, and the more jobs it will create. A pessimist who focuses only on the smaller number of jobs destroyed, and refuses to look at the greater number of jobs created, will mistakenly conclude that technological disruptions cause net reductions in employment. When people put blinders on themselves like that, it would be merely sad if it weren't also dangerous: if a critical mass of people come to adopt that Luddite view, there will be an economic collapse.

  20. You can't be serious on The Internet's Network Efficiencies Are Destroying the Middle Class · · Score: 1

    Are you seriously proposing that we should intentionally introduce inefficiencies into processes, in order to boost employment?

    That's not how it works. Improved productivity is what results in higher standards of living and more jobs. New technologies create disruptions, to be sure, where workers have to shift out of fields that are no longer in demand (your TV repair example) -- but in spite of this, the fact is that there are currently more employed humans than at any other time in history. Every new technology creates far more jobs than it destroys.

    To introduce inefficiencies -- in other words, to intentionally lower worker productivity -- is an incredibly short-sighted idea that will doom us all to lower standards of living.

    In the classic example of workers building a dam, the superficial analysis is that you'll employ more of them if you take away their heavy equipment, and force them to dig with teaspoons. But the correct analysis is that you'll employ none of them, because without the efficiencies of heavy equipment, the authority that wants to build the dam no longer has enough funds, and has to cancel the project altogether.

    You couldn't be more wrong, and if there's one thing that will doom the human race it is this mentality.

    The fact is, there are currently more humans employed than at any time in history. And the vast majority of them are employed in fields that did not exist before certain enabling technologies were invented, whether they be electric power, or internal combustion engines, or mechanical hair clippers (a favorite technology of my barber -- without which I would not be able to afford his services as often). Every new technology creates far more jobs than it destroys. There are far more people working in the auto industry than ever worked in the buggy-making industry. Do you imagine that there were more telegraph operators in 1905 than IT workers in 2014? No: every new technology creates far more jobs than it destroys.

    The more disruptive a technology is, the more jobs it will create (and the more it will be condemned by Luddites who just don't grok how the synergistic cumulative effects of small efficiency improvements in myriad industries add up to huge improvements in humans' standard of living). If your standard of living is better than that of your great-grandparents, who likely physically toiled in agricultural occupations with not a lot of assistance from machinery, you have technology to thank. Don't dream that weak technologies, with their weak job-creating effects, are better than the really disruptive technologies.
