Submission + - Researchers identify 'tipping point' between quantum and classical worlds (rdmag.com)

wjcofkc writes: If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons — the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's because the physical behavior of photons — similar to electrons and other sub-atomic particles — is characterized not by classical physics, but by quantum mechanics.

Now, in a study published in Physical Review Letters, scientists from Bar-Ilan University have observed the point at which classical and quantum behavior converge. Using a fiber-based nonlinear process, the researchers were able to observe how, and under what conditions, "classical" physical behavior emerges from the quantum world.

I was thinking more like intersolar trade. Water goes on giant ships to the moon every so often, and helium-three comes back. If it turns out to be to impractical to colonize distant worlds for a very long time, we must assume the colonization of the solar system works out barring we don't set ourselves back or completely annihilate ourselves, this could start to take shape in a century or so. Different places in the solar system have different resources, ships sharing resources would need to be in constant transit.

The black hole in question is eating matter near the rate of what is theorized to be the limit of how fast a black hole can consume matter. We've really never seen anything like it. ~875,000,000 is very young for such a structure to be so big in a universe that young. Anyway, when it is said that it is the brightest object in that part and time of the universe, we are speaking of the "extra bright" event horizon: the point where matter is super heated before tumbling into the singularity itself. Since it's all one dense gravitationally bound structure, the event horizon is part of the whole. The great part of this discovery is that it allows us to take a peek at ratios of elements such as hydrogen and helium relative to heavier elements in a still pretty young universe.

We've been following the development of this sort of technology here on Slashdot for a long time for sure. In fact, I find this area of research and development to be among the most fascinating of our time and am course always glad to see people getting help from them. However, I won't be truly impressed until someone can peel the Orange away with the bionic hand using nothing more then the same part of our brain that we would use to control that function in the first place. Perhaps the next time a story like this gets posted.

Comment Re:As a Windows Phone user (Score 1) 85

If I had mod points I would reward you just for admitting to being a Windows Phone user around here. But then again, so am I. My phone is on the list of phones eligible for the insider beta test, however, after doing research beyond the scope of the linked to articles, I find that the trade off in features is currently unacceptable. For example a slightly crippled Cortana among other things. Perhaps in another month. I have been on board with the Windows 10 Tech Preview since day one and the current builds not only feel finished, it has become my daily driver. I will likely get one of these: Acer Aspire R7-371T-50ZE when they come out, and of course put Windows 10 on it. I am a long time MS basher, but I like where they seem to be headed so I jumped on board.
