Trouble with NK is, they don't have second strike capability, so a disarming first strike from the US is possible and NK knows that. That puts NK in a use it or lose it situation with their nuclear weapons and it may be, that the regim

In general relativity you can easily show with Noether's theorem, that in an space time with rotational symmetry there is a conserved quantity that in flat space is conservation of angular momentum.

Even with full disclosure, what is a poor person supposed to do? It is precisely the rich who could mitigate the risk, by either buying insurance or by building to a high enough standard. Poor people have to hope for the best, because the s

The problem is "reasonably expected." For an recent example consider the 70.000 Tinder (?) profiles now located on the piratebay. The guy who did that was likely preoccupied with questions like which scraper to use, and just never

Well my story with the research bureaucracy is, a coworker had to fill out a notice that he got some money for a conference from outside the university and he dutifully filled out everything. Thing is, as a theoretical physicist you are sup

Yes, though one has to go through quite a bit of trouble to actually show that. The big problem is, that speed of light is defined with reference to a background geometry and gravitational waves are a distortion of this background geometry.

The fundamental problem is, that hard science fundamentally can not do that job. A policy document is a normative document, science produces descriptive accounts. Even if we assume for a moment that we had a full scientific theory of gender

Nobody is arguing against rational discussion. The problem is, you can not have a rational discussion about what rational discussion means, since all parties would need to agree on a position in the first place to have a rational discussion

Any label needs context, consider the label "3" or even "9 m/s^2," the first can refer to anything the second to an acceleration or to a gravitational field strength. In the case of weather, "extremely hot&quot

Yes, however the NYT mentioned yesterday, even if the brains are the only cases of CTE, then the incidence rate among players would still be vastly higher than in the general population.

We are already in a failure state, the camera did detect a cyclist that is not a cyclist. At this point motion detection will do something, but since the back of the car transforms differently than a real cyclist, this something is at best

Short answer, MIT discovered unobtanium and now fusion looks pretty good. Longer answer, the crucial part in a fusion reactor is the magnetic confinement and with the field strength conventional superconductors can manage you need a large r

The fun thing about it, is that Spielberg directs the movie. (Also, the book should lend itself to a movie adaption.)

If you are a fan of 80ies nerd culture and you want to read a well written but not very deep science fiction book, it is a quite entertaining read.

In general the problem with hydropower is, that it is the best energy source if you have the location. Therefore the good locations were developed early on, Hoover dam in the 1930ies, Aswan dam in the 1960ies, and now we are left with margi

The electromagnetic force does not know the true distance, here the ruler is more of a theoretical construct. Perhaps it helps, if you think about it as moving the underlying coordinates vs moving the particle. (There is no difference betwe

Just tried it, cat /dev/zero|pv >/dev/null gives me roughly 2/3 the speed of yes. (5 GB/s vs 7 GB/s) Plus yes gives you an arbitrary string, instead of only zeroes.

The ability to get 10 GB/s dummy date into a pipe from the command line could come in handy at some point, for stress testing or something. I am not sure if it is over-optimized. (And even with the optimizations the risk of bugs should
