It's a lot more than solid state physics

"Deloitte says the low price of smaller tablets is the reason for their surge"
"Deloitte says refresh cycles are slowing as punters hang on to their gadgets for longer, a reflection of their increasing price"
Deloitte says tablets are getting cheaper and more expensive at the same time. Why should we listen to them?
The pro uses the PCIe to maximise bandwidth to the video cards. There aren't enough lanes to have PCI slots and TB externally, so they have dumped the internal slots in favour of external expansion.

If you have an optical microscope, you can actually get quite good images by holding a cell phone camera up to the eyepiece - a few mm of shuggling about - look for a bright flash to show you are in the focus of the microscope lens, then slowly move it towards and away to optimise illumination of the camera sensor.
At least, it works for my kit. YMMV.
It is likely to be operating in an more complicated/ even cooler system than liquid helium. The article says it cooled the copper block from 290 mK, which means they probably used a dilution refrigerator to get there, since liquid helium boils at around 4 K (-269 C).
From Wikipedia: Precursor to chemicals
In the chemical industry, carbon dioxide is mainly consumed as an ingredient in the production of urea and methanol. Metal carbonates and bicarbonates, as well as some carboxylic acids derivatives (e.g., sodium salicylate) are prepared from CO2.
There is also some work looking to make green polycarbonate plastics from CO2, though it is early stage and unlikely to make a significant dent. The main (hopeful) future use for CO2 is to use it as a feedstock to make fuel, which is about the only chemical we need at scale to make use of the amount of CO2. This does of course take energy, but if it can be supplied from a renewable source, future CO2 release from fossil fuels would be reduced or eliminated. Methanol can be made from CO2 for example, and there is also the dry methane reforming reaction to make syngas, which can then be used to make liquid fuels via the Fischer-Tropsch process. This is arguably nicer than steam reforming, but people are unlikely to stop that, since the hydrogen it produces is much more valuable. There may be a role for small installations, but it often makes more economic sense to flare methane than transport it to market.
There are some uses for CO2 that could soak up some of it, but generally these demand a pure CO2 stream, so it is useful as a step in the recovery/re-use process. The research looks nice, but I would worry about the resilience of the MOFs, especially at the elevated temperatures likely to be used in gas flue streams. (Temperatures up to 30 C reported in the paper) and likelihood of poisoning in real gases.
Yes, iphone same since 2007. Apart from
4 case designs
doubling screen resolution
6? operating system versions
3 SIM sizes
moving to LTE from GSM via 3g
starting an app store, which has generated $8 billion for developers
quadrupling the cameras pixels whilst increasing aperture
doubling the number of cameras
doubling processor speed over five architectures
octupling system memory
But apart from those, totally the same.
There are not that many laptops available with 22 and 27" screens. If you want a big screen, but don't want cables, clutter and so on, it is a fairly good option. As for price/performance it may not "perform" in the way you want it to, but that does not mean that it doesn't perform well in features that you obviously don't care about such as looks, size, and quiet running.
You could not make a PC that thin, with a display as good that was as quiet in running as the mac. Thinness and quietness do not matter to everyone, but they matter to some.
From the article: "Still, one thing is a pretty safe bet: over the long haul, openness generally wins."
Really? It seems to me that closed generally wins. It isn't like linux is the dominant OS. I can't think of a single field in which this is true. Of course, the wording of the sentence also has that little "generally" in it to rob it of any conviction, in case the bit about betting in the first half didn't clue you in..
Android phones outsold iOS phones. This does not take into account other iOS devices, such as the ipod touch or iPads. iOS devices are more homogenous, so you don't have to worry about hardware differences as much, and iOS users are also more willing to part with money for apps.
In an ideal world, developers would port for all platforms, but the fact is that iOS is the most attractive target for limited resources.
Interesting choice of macro shots which, erm, aren't. I have an LX3 and recommend it highly. It will focus down to 1.5 cm in macro mode and give a great close-up. Also, due to the lovely fast lens it is great in low-light conditions which allows for decent indoor photos without a harsh flash.
I'd suggest anyone properly interested to go and have a look at the flickr camera search.
