I have glaucoma, giving me the classic arc-shaped loss of visual field in each eye. Bottom line is that I really need both eyes at the same time to get a decent 2D view. Persistence of vision notwithstanding, alternately displaying images to each eye just doesn't add up well when each eye is depending on the other to fill in missing data. I can usually perceive the 3D effect, but at the cost of most detail in the middle of the image, and overall dramatic reduction in brightness vs. a 2d display.
I'd rather have a high quality 2D image than a crappy 3D one.
Where do *you* get your information about the appointment process? As long as the President is willing to take the political heat for it, the appointment process provides (http://en.wikipedia.org/wiki/Recess_appointment) a method for Obama to appoint heads to those agencies.
The R's have keep Congress in session via the farce of keeping one clown in DC to gavel in 1 minute sessions each day. No recess = no recess appointments. Thanks for playing.
Airlines would go out of business very rapidly if they weren't running at near capacity and with overbooking. If passenger demand goes down, they attempt to minimize the bleeding by simply scheduling fewer flights or cancelling flights that check in under the magic number that makes them profitable. (Happens routinely if you're flying into/out of an out of the way airport.)
They will still feel the pressure of reduced demand though - idling expensive assets eliminates the fuel cost, but they still need to pay off the airplane capital cost.
There is a saying, I keep hearing: "No-one ever got fired for choosing SAP"....
Not a developer and certainly not a SAP consultant. But I did live through implementation of SAP at a Fortune 500 manufacturing company. For all practical purposes, the CEO bet the company by committing us to implementing SAP. The project cost was something like $3e8 in a company with sales of about $3e9. You spend that kind of cash, you bloody well better recover it in improved profitability.
Politically, with those kinds of stakes, the project is going to succeed. If it isn't a success, reality will be adjusted to make it a success. The only people getting fired in an SAP implementation are those stupid enough to say that it isn't succeeding.
carbon spontaneously forms many different shapes, not the least of which are C60, nanotubes, and graphite (which has a honeycomb shape). As cool as this is, what part of this is "news?"
All the examples you give are covalently bonded molecular structures, where the observed regularity is derived from the symmetry of the orbitals forming the bonds.
What's cool about this (as near as I can tell from the junior high-school level article) is that the structures are supramolecular, many orders of magnitude larger than the anthraquinone molecules they are made of. The structures seems to be held together only by (weak) van der Waals interactions between the molecules, influenced by the copper substrate. This is interesting and unusual, if you know enough chemistry to appreciate it.
I'd love to see x-ray diffraction of these layers, to see how the anthraquinones are packing, and how the symmetry of the molecules is reflected in the much larger honeycomb.
My favorite "what if": What if copy/cut/paste worked in Excel like it does in every other Windows program? It drives me crazy that the stupid clipboard forgets what you copied if you do anything other than paste.
Perhaps not. With a car, you have millions of little gas-producing factories running around. So, in order to reduce emissions, you have to have millions of little catalytic converters. You also have to make it fit in around a cubit foot of space.
Yeah, what he said.
I'd add that you also don't waste energy dragging the pollution control hardware around with you while you drive, which will also contribute to reduced emmisions.
If he were dead, Tufte would be rolling in his grave. This thing is simultaneously an incredible example of chartjunk and low information density.
The image of the galaxy is what Tufte calls a "duck" - a decorative style element that dominates a chart without conveying useful information. The color coding is also chartjunk; it conveys nothing that isn't already implicit in an element's location in the chart. Most of the ink in this graphic (galaxy, color fills) conveys zero information.
It gets worse. To keep from obscuring the cute galaxy picture, the designer shrank the atomic numbers to an illegible point size, and then threw away useful data (like atomic weight, electronic configuration and common oxidation states, all of which fit into a rather smaller chart than this which is hanging on my wall.)
But what exactly is the worry here? It deletes files in your download directory? Does that really matter? Could someone enlighten me on why its worth the bother to uninstall and reinstall for this?
1. Suppose your download directory isn't dedicated to just downloads. Any files in that directory are vulnerable.
2. You don't need to uninstall and reinstall. As the article says, just go to tools: options: advanced: software updates and hit the Check Now button
Grandparent: Still, keep in mind that Firefox was originally meant to be a Windows program (but it doesn't hurt to be available on multiple platforms though, which I'm definitely in support of).
Parent: Do you have a reference to this intention?
Firefox grew out of the desire to make the best browser for Microsoft Windows. Eventually we began to build on Linux as well, and also Macintosh. Most of our development work is done on Windows, and so that platform naturally tends to lead although we express a desire to work as well as is feasible on every system we can.
Right. That's why you need so much lead shielding around medical Co60 gamma ray sources.
Air is essentially transparent to gamma, and above ground tests can be easily monitored from orbit. Astromonical gamma ray bursts were originally observed by US spy satellites sent up to monitor Russian atmospheric tests.

Ringworld, the directors special cut edition?
Ringworld was one of the first SF novels I bought as a kid, when I ran out of material at the local public library. My copy is a first edition where Niven's got the world rotating backwards during Louis Wu's attempt to stretch out his birthday via teleportation. The newer printings have all been digitally reworked to cover up the mistake.
I'm pretty sure that in the newer printing Nessus fires the tasp at the exact same time that Speaker to Animals is swinging the variable sword, but I'm too cheap to buy a copy to check.
Harry Potter is the most known one but Philip Pullman's "His Dark Materials" is clearly anti-religion and anti-church (and a very good read).
It does kind of astonish me that "His Dark Materials" has apparently slipped under the radar of the religious right.
The Harry Potter books are pretty simple stories of good vs. evil, and as such are fairly compatible philosophically with Christianity, but have some superficial red flags that a Christian religious nut can grab onto.
OTOH, Pullman doesn't offer up the easy flags (no School of Witchcraft!), but the story itself is much more subversive, leading the reader to question the ideas of good and evil that Christianity attempts to inculcate.
I'm in the middle of reading the Pullman novels aloud to my two children. Questioning is good.
The amount of heat being generated by chips does not seem to be decreasing at all, and this material appears to be produced to be "heat resistant" instead of more efficient.
Heat resistance isn't the point -- current IC's don't melt, they get trashed via difusion processes that will still be there in SiC.
The advantage of SiC is substantially enhanced (2x) thermal conductivity vs. Si. This makes it easier to get heat out of the chip, allowing it to run cooler at any given heat production rate.
I just finished the PG edition of Joyce's Ulysses. It's a difficult but rewarding read. I loved having it available as an etext, but I have to say, the proofreading was marginal at best. The entire last chapter had no punctuation marks at all!
Seriously, the text was in pretty bad shape, with lots of common OCR errors: 1 = I, 5 = S, b = h, etc., chapter titles missing, etc. Does DP take on new versions of existing PG books? I'd volunteer to try and do a better job on Ulysses.
Another scientist chipping in, and I couldn't agree more. I've been using a HP15C for about 20 years now and live in terror of the day it dies, because I can't replace it. I had and loved a HP32 that died; but I like the form factor of the 15C better.
I don't want my calculator to do mediocre graphing or mediocre symbolic logic or mediocre numerical analysis or mediocre monte carlo simulation, yadda yadda yadda - for anything complicated, I'm going to use my workstation with a big display and high end software. I don't even need programability in a calculator, although it's useful (I wrote a nonlinear regression package for an HP41C that deconvoluted NMR spectra for my thesis - today I'd just do it on my workstation).
I want an RPN calculator with good buttons, enough of them to expose all the functions I need without plowing through nested menues, but not so many that I need to go hunting to find things. I want a good solid-segment LCD or LED display for high contrast and wide viewing angle; I don't need or want alphabetic characters or graphics. One display line is plenty, but make the segments big - my eyes aren't as good as they used to be. I want a small form factor so it'll fit in my pocket, and essentially infinite battery life so I don't have to worry about whether it's charged.
I want the HP-15C to go back into production. I'd buy three or four immediately and scatter them about so there's always one in reach.
Color matters a lot for reading legibility, even with black and white text, because many/most high end doc readers do subpixel antialiasing on color displays these days.
I use both PalmReader Pro and TealDoc on my Tungsten T3. Both do subpixel antialiasing, and the text is noticably nicer on the eyes when you turn this option on. The big 480x320 screen on the T3 is very nice for reading.

It is not you on the plan the TSA cares to keep safe. It is what the plane can crash into.
And how exactly is a bomb smuggled on board going to enable a terrorist to commandeer a plane and crash it into something?

And that just great until we run out of witches. Doesn't anyone think these things through? It's not scalable.
Converting most oxides to O2 costs energy, usually a lot.
Converting perchlorate to O2 is energetically downhill. You get O2 plus some heat for your igloo.

Ok. I believe I'll have a Shirley Temple, no little umbrella, extra fizzy water.
And if you could drill for elemental hydrogen, it'd make sense to talk about a "hydrogen economy".

No. Well, sure, you can make a conductive composite by filling a polymer with metal particles, but that's not what is meant by "conductive polymers".
The prototypical conductive polymer is polyacetylene. In its conductive state, it is shiny and looks like a metal.
