But what do I know?
As to my absence I've been a bit overwhelmed by work stuff, sorry about that, it's no excuse
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.
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.
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.
I wonder what it would take to make it safe down to 40 meters, the limit for recreational divers. Use your phone as your dive computer and to take pictures while you're down there. They already make wireless regulators; they can't be hard to adapt to Bluetooth. (I have no idea what the range of Bluetooth is under water.)
Is anybody making a phone with no jacks at all? Just wireless charging and Bluetooth headsets? That would give you a great opportunity to really seal the device.
Right now not having a charging jack would prove a bit of a pain, but for a specialized heatseeking kind of market I could see people getting into a really ultra-thin phone completely devoid of the need to accommodate any connectors.
