    I've been wondering about that. I've got a heat pump, and one down side is that it fares poorly when the weather is significantly below freezing. It's been a wicked couple of winters around here in the Mid Atlantic, and it would have been nice to tap into a huge store of moderate temperature just a few feet below ground.

    Many countries are phasing out coal in favor of natural gas, which pollutes less and (due to fracking) has dropped considerably in price. It costs around $1.99 per gigajoule today (http://www.eia.gov/naturalgas/weekly/).

    Note also that not all environmentalists are in favor of ending nuclear energy. New nuclear plants are being built now, approved by the Obama administration: "DOE’s investments in nuclear energy help secure the three strategic objectives that are foundational to our nation’s energy system: energy security, economic competitiveness, and environmental responsibility." (https://www.whitehouse.gov/the-press-office/2015/11/06/fact-sheet-obama-administration-announces-actions-ensure-nuclear-energy). There is indeed a quandary among environmentalists because the issue of nuclear waste is contentious, but many in the environmental movement recognize that nuclear power can be part of an overall strategy in reducing carbon emissions.

  3. Gripe: Math versus Science on Are We Alone In the Universe? Not Likely, According To Math (cnet.com) · · Score: 1

    Science is respected for its reputation for certainty, and Math is seen as the purest (and thus most certain) of the sciences.

    This bugs me. Math, on its own, is so "pure" that it has no connection to the universe whatsoever. Aliens don't appear in pure math. Neither do electrons, polymers, or three-toed sloths. Math is purged of all real world things. Math can't predict anything about the real world. Even the simplest tautologies, like "two apples are equal to two apples", requires extra real-world semantics to apply an abstraction like "equal" (which has many different definitions) to actual things like "apples".

    So when people say "according to math", they're aspiring to a certainty that it doesn't earn. You could say "according to science". Science will always incorporate some form of math. But it's not identical, and if scientific claims seem "weaker" than math claims, we just need to live with that. Because we don't, in fact, really truly mathematically "know" anything about aliens. Not even a probability: our probability estimates are themselves subject to enormous amounts of guesswork.

    Sorry for the distraction, but this bugs me. The article itself doesn't seem to be of much merit; it's all old news. So I'm gonna gripe about the headline instead. Thank you for your time.

  4. It's a bit more complicated than that, but the conclusion is correct.

    You're describing a local hidden variables theory, in which the particles already have a definite value at the point where they were entangled. That doesn't quite describe reality; with some subtle experiments you can see that they interact in ways slightly different from ones that are already set. But that difference still doesn't allow you to communicate.

  8. Re: Dangerous on New Heating Technology Uses Seawater and Carbon Dioxide (csmonitor.com) · · Score: 1

    You can think of a heat pump as a reversible refrigerator. In cooling mode, it works just like a refrigerator: the compressor compresses gas, lets it radiate heat of compression outside, then pumps it inside to evaporate.

    The remarkable thing is that you can turn the process around to heat the inside instead of the outside. You compress the gas outside to make it hot, then pump it inside to release that heat. A carefully-designed valve causes it to go from liquid to gas, or reverse, depending on where you want to absorb heat: outside, even in winter, the evaporated, chilled gas can be warmed up by the outside air.

    The trick is getting the right refrigerant, which turns from liquid to gas and back around the temperature you want. I dunno why they've chosen CO2 here, but I suspect it has to do with the ambient temperatures in Alaska.

    It shouldn't have come as a complete surprise, though. She's always had high negatives, though it's disappointing that so many of them come from concerted Republican campaigns to smear her. (Remember that Barack Obama had a fightthesmears.com site set up the minute he won the nomination.) It's unsettling to have liberals repeating Republican talking points, in addition to creating their own.

    It set her up for there to be some kind of opposition. And the Democratic party has been taking its liberal wing for granted for quite some time, allowing centrists like Obama and both Clintons to get their votes knowing that they'd be unable to get more than the palest pink liberal agenda items actually achieved. I happen to be a left-leaning centrist myself, and think that's about the right thing, but real leftists are understandably upset.

    In the end they have the opportunity to realize that they've dragged one candidate a bit left, and get that candidate elected over a far-right candidate. That would be a win, and if it's not the win they were hoping for, it's also the one that doesn't have every Republican and half of the Democrats upset at going too far left. We'll see if they'd rather have half a loaf than none.

    If you eliminated unpledged delegates entirely, Clinton's target would be 2,113; she'd need less than 700 of the remaining 1,646 delegates to win.

    You're right that they only say "ally" because it's far from clear that they actually ARE our ally.

    But the Saudi government does cooperate with the US on a lot of things. They're often the targets of the same terrorists that we are. Their intelligence agencies coordinate with ours, and provide a lot of the information that goes into the US "war on terror".

    The problem is that the Saudi "government" is a weird thing. It's a kingdom with literally thousands of princes. Many of whom are insanely wealthy, and some of whom actually support terrorism, including terrorism against their own country. That's not an "official" policy, but neither does the Saudi kingdom go out of its way to arrest them, either. Why exactly those princes support violence against their own country and their own family, biting the hand that feeds them caviar... well, let's just say It's Complicated. But they do.

    So they say "our ally Saudi Arabia" because it is our ally... often against itself, which is our enemy and its own.

    It's even more complicated by the fact of oil; for decades we relied crucially on them. And that's growing more complicated as our dependence grows less. So we're less willing to put up with the support for terrorism, within the family and within the government. We do, in fact, need their help, and simply trying to prosecute Saudi family members (if not the government itself) will make that complicated situation even more ridiculous.

    So... I got no idea where we go from here. I see the threat to sell bonds as a really weak threat. The fact that they have those bonds was, in fact, a favor to us, helping prop us up during the economic crisis. But we don't really need that any more; plenty of people are still desperate to buy our bonds. The price of oil has collapsed their cartel.

    The government wanted to be our friends, but not at the cost of loosening its own power. Now that's failing, and their options are few. I dunno what happens from here. Those 28 pages won't have nearly the "smoking gun" that people imagine it will, but they won't be pretty either.

    They might even let them sign up for the same company. A few days lack of service, plus a reconnect fee, might convince them to cut out illegal downloads (or at least, try harder to hide it).

    It might end up with all of the downloaders at the one ISP in town who tolerates them. But I suspect that the other ISPs might have ways of putting pressure on them. Especially if they're also the backbone provider, such as in Verizon's case. Even if not, they may be able to tell the backbone provider, "Look, we're losing customers because they're not playing fair, and we'll complain to your peers if you don't tell them to knock it off."

    It is surprising. I'd go so far as to say "stunning". This kind of ML is really, really fallible, in exactly the areas that humans do well. I'm kinda baffled.

    I darkly suspect that it means that humans aren't really very good at Go. The combinatorial explosion is so fast that the vast majority of moves don't get any consideration at all. Humans apply a well-trained intuition, but there's reason to think that good moves are completely ignored.

    In chess, the best computers play slightly better than the best humans; it's as though we're near perfect play even if we can't actually work out all of the routes for all games. In Go, it sounds as if in the near future humans won't even be in consideration; you'd no more ask a human to play Go against a computer than you'd ask one to race an automobile.

    Which is to say: perhaps the explanation is that the computer still isn't very good. It's just better than the extremely-fallible human.
