The 5x4 layout seems pretty unremarkable -- should each phone manufacturer have to trademark their own layout (n,m), for nonzero integers n,m? Will small players be forced to adopt button grids like 21x1 if they can't license actually-usabl

Why not just sterilize it with gamma radiation? A WHO link I found claims that high-dose irradiation (>10,000 grays) is substantially safe and will sterilize food, but Wikipedia says this is banned in the US except for hospitals and NAS

Well, then at least we should increase the number of immigrants by upwards of 10% per year until a point where nobody is turned away. I see where you're coming from (trying to avoid economic shock with abrupt policy changes), but since mi

How does having poor people living and working in the same country as you make you poorer? Your ideology looks to me like socialism except in reverse: you want to restrict free capitalism in order to keep the poor segregated and in povert

The price of thermal coal (USA) is averaging around $2.26/million btu [1]; the average heat rate (inverse of efficiency) of coal plants is 10,414 btu/kWh electricity [2]. So the fuel component of cost is about 2.35 cents/kWh, or for a 500 M

The New York Times was writing about concentrated solar power as early as 1868, in the context of the imminent exhaustion of coal. http://select.nytimes.com/gst/abstract.html?res=F40A10FB3854...

The NREL figures are for plants with heat storage (large tanks of high-temperature molten salt which accumulate heat, to power turbines at night). Without heat storage you only have 20-25% at most. Ivanpah has a capacity factor of 31%, but

Economics is the study of decision-making in the presence of scarcity. Scarcity exists. Tradeoffs exist. The tradeoff between money and natural environments exists, and making choices by definition involves making comparative value judgme

Not really. It's not rare, it's 1% of the atmosphere or about 50 trillions tons. And it's not essential for neutrino detectors anyway. http://en.wikipedia.org/wiki/Atmosphere_of_Earth Besides, I'm certain my numbers are large overestimate

Not really, it's only about 40 meters in diameter. With trillions of dollars at stake, I imagine they'd find a way to bury one under lower Manhattan. I've found some figures here -- this is an experiment which creates a focused neutrino bea

I notice they restrict themselves to the surface of the earth. Out of curiosity, is it feasible to use modulated neutrino beams to communicate straight through the center of the earth? You could theoretically shave up to 24.3 ms in latency

The problem here isn't criticality but waste heat : heat generated by uncontrolled radioactive decay of waste products (fission products and products of neutron activation). There's no way to turn off this heat; it continues uncontrollably

Then your ideology and your proposal are completely inconsistent. Rich countries will be flooded by poor and unskilled immigrants. These immigrants will then vote and fight for a redistribution of the wealth (through social services, etc..

The attribution here is correct (Matthias Braun, Areva); the name and logos were stripped when it was released, apparently for some kind of legal reason. This is discussed at the end of this article: http://www.nytimes.com/2011/04/03/scien

I don't claim that they don't admit low-income workers, but that their laws discriminate in preference of high-income workers (that is, highly educated professionals). See their points system [1]. (It also discriminates on the basis of ag

Genuine confusion here - are you taking the position that nations should not discriminate when choosing who they allow to immigrate, My position is that states shouldn't be empowered to allow or deny immigration, because freedom of moveme

I'm sorry, I wasn't clear. I was talking about the "how hard it is to immigrate part"; if you deny them entry, you are denying them access to your economy and its opportunities.

by uvdiv 16y ago
A straightforward way to address this issue is to deploy a point system currently used by several countries, including Canada and Singapore. Plainly, to tolerate laws that explicitly discriminate against low-income and blue collar workers

It's a horrible irony that a well-intentioned welfare system was a major factor leading to this economic repression. But if you have an expensive safety net for everyone in your country, then you can't afford mass immigration (because of re

That's less than $200k to lift the mass of a 180lb human. No, it's $80-$125 million to lift 650 humans, packed like intermodal containers in stacks roughly 20 bodies high. Which technically amortizes to ~$150k/sardine, but I don't think

I still remember the voices after Chernobyl: Light water reactors are safe and core meltdown can never happen, because the moderator is water. If it evaporates, the moderator is gone and the core will cool down. You misunderstood. No one

The article screwed up the units: it is likely "0.809 microSieverts per hour ". Your link's figures are over one year.

It doesn't even mention the 4th, There are six, and units 4,5,6 were already in a cold state before the tsunami (for maintenance); they're not involved. You could be thinking of Fukushima Daini, which has four reactors.
