Different journals have different standards for the type of paper. For example, the format for Science and Nature articles tends to be less detailed and more focussed on the particular result obtained. Other journals are more suitable for more in-depth discussion of methods and their intricacies. Some of them, such as Physics Letters, promise rapid publication, whereas PRL etc., Science, and Nature can drag on for some time. Notice also that they have chosen to publish the papers open access, which not every journal allows. Impact factor isn't everything. And as another poster noted, there is a Science article in the works. Nothing fishy here.
QED does not have lots of pictures in it. Physics books for the layman tend to not have many pictures. Physics textbooks are much more equation-heavy than picture-heavy.
So this paper is about that very first step of actually making the qubits. One atom = one qubit. In this case, the "state" would likely be the atom's spin orientation. Spin and position are not connected by the Heisenberg uncertainty principle. Position and momentum are linked, as are energy and time.
I'm not really sure what your question is, but I'll try to answer it! To make a quantum computer, you need a number of qubits. If you want to use atoms as qubits, you need to be able to repeatably trap, hold, and interrogate them over "long" timescales. If you could only trap a single atom 50% of the time, your computer would be very inefficient if you have, say, 30 qubits (ie. an array of 30 single atoms). By pushing this up to 83%, efficiency improves dramatically. Also, they can probably do better than 83% by improving their vacuum, but this would require taking their apparatus apart somewhat, and is not something people tend to do once they have a working setup!
Yes, definitely ebay! Old analog scopes are just as good as digital scopes (in some cases preferable), but it depends on the application, and you can fix them if they break. If you need a really fast scope or want math functions, then you need a newer one. We have a few digital Tektronix scopes in the lab, and they are just fine. Also, what is handy with newer scopes is that they have USB ports so it's easy to save your data (if you need to).
The underlying quantum state *is* observable. Why wouldn't it be?
If you RTFA (and not even the paper is necessary for this), you will see that they are limited by the fidelity of their setup, ie. signal to noise. Hence, when they improve their apparatus, they will get more accurate results.
My parents bought my sister a cell phone when she was 11 so they could keep track of her. There wasn't any issue of "responsible use". My dad tells her that she always needs to keep it with her and that's that. I think the other kids her age had to beg their parents for cell phones...
I also would like plain LAN play for Diablo III. Where I live, internet is still fairly expensive and the data caps are not liberal. I want to be able to play the game with my friends at home without needing a net connection. I loved Diablo II for the LAN play. If Diablo III will have no LAN play, I won't buy it and would encourage others to boycott it also.
As a person who works in a laser lab, I was very offended that existing green laser pointers were dubbed "fake". If anything, having a hand-held diode pumped solid state laser is way cooler than just a plain green laser diode.
Usually what happens is that someone wants to build on another person's research or use their method for their own experiment. If they just can't get the method or experiment to work, questions will be raised, especially if multiple research groups can't get it to work.
Yeah! When I get into a game, I lose the desire to eat. I think fostering a gaming addiction would be a great way to lose weight because you stop caring about the outside world and your own bodily desires and functions.
So IMHO, they're worse than regular cops. They're bored out of their minds - and have real guns. They so desperately want some crime to deal with, but there just isn't much other than the odd frat house kegger that gets out of control or the occasional parking ticket. I'd be bored to near-insanity too.
Our campus cops are not real police. If they see something happen, they can report it or in some cases "apprehend" someone until the real police arrive.
There was an assault on campus last week. The aggressors were around 20 years old. To my sheer amazement, our overweight, mid-30s or older, smart-ass campus security people actually chased them down a few blocks and caught them. There must have been some catch to the story. Perhaps the assailants were overweight, crippled, high or something that would have disadvantaged them somehow...
And you need a complete step-by-step photo walkthru down every residential side street? I can see the value of google street view for finding a business; and given the choice, most of them will opt in to such a system. But why do you need a photo of every residence in the city?
As a person without a car, I find photos of residential areas extremely useful when flat hunting. When someone is advertising their house for rent, they usually only post pictures that make the house look good. I was so happy when google did my town, because instead of "driving past" (which real estate agents here always tell you to do before they actually show you the house) I can just look it up on street view! It gives you an idea of the quality of the neighbourhood, position of the house relative to the sun (hilly town, so you don't want to get stuck with a house that gets no sun), and anything else you can find out by driving past the house.
Perhaps there is more to the article... Have they compared people from cities to people who already live in the countryside? A person who grew up in a big city would be used to all the stimulus, so when the extra "load" is removed, they improve 20% according to TFA. Does this 20% surpass the mental abilities of people who grew up in the countryside?
So city people are some kind of mental superhumans, and once removed from their highly stimulative environment, they ourperform the non-city people.
I've been using Interclue for a while now, and it's not as you describe it. It is actually useful and unobtrusive. The little window only opens up if you mouse over the small icon that appears next to the link. It isn't anything like Snap which is horrendously annoying.
God forbid they ever find out that sometimes multiple people play the same game on the same computer or console. To think that you can go to a friend's house and play while they are busy with something else! Amazing!

It is the first time single Rb-85 atoms have been trapped.

You can slow light down, speed it up, and even stop it altogether!
