What 'Negative Temperature' Really Means 204

Posted by Soulskill
from the not-a-car-analogy dept.
On Friday we discussed news of researchers getting a quantum gas to go below absolute zero. There was confusion about exactly what that meant, and several commenters pointed out that negative temperatures have been achieved before. Now, Rutgers physics grad student Aatish Bhatia has written a comprehensible post for the layman about how negative temperatures work, and why they're not actually "colder" than absolute zero. Quoting: "...you first need to engineer a system that has an upper limit to its energy. This is a very rare thing – normal, everyday stuff that we interact with has kinetic energy of motion, and there is no upper bound to how much kinetic energy it can have. Systems with an upper bound in energy don’t want to be in that highest energy state. ...these systems have low entropy in (i.e. low probability of being in) their high energy state. You have to experimentally ‘trick’ the system into getting here. This was first done in an ingenious experiment by Purcell and Pound in 1951, where they managed to trick the spins of nuclei in a crystal of Lithium Fluoride into entering just such an unlikely high energy state. In that experiment, they maintained a negative temperature for a few minutes. Since then, negative temperatures have been realized in many experiments, and most recently established in a completely different realm, of ultracold atoms of a quantum gas trapped in a laser."

What's the alternative? A sound of some kind can be very useful when taking a picture - making it unique is also useful, and it doesn't really matter if kids these days don't know the etymology. Ditto saving - it's pretty much an entirely abstract concept these days, but it still needs an icon.

I've noticed a disturbing sharp turn to anachronism in the tech field lately.

There's been no "turn" - there's just nowhere else to go.

Slashdot discussed this issue earlier in the year, for those interested:

The summary leaves out the interesting part: IE8 is the latest version available for Windows XP. And there's no place that XP exists more than business, education, and government. This is Google's way to get sysadmins comfortable with Chrome in the workplace.

Having read the FA (hanging my head in shame (which is stressing my youvh yypinh dkilld) ), it looks like this is only touching upon the web-access apps.

Does anyone know if there are Google Appliance apps, similar to Google Search appliances? I know that I've run across Google search appliances on small & large scales (various gov-controlled, closed networks), but I've not seen (or recognized) any implementations of their apps on these aforementioned appliances.

It seems to me that affecting _those_ networks would really be turning the screws on XP.

+ - The Chaos Within Sudoku - A Richter Scale Of Difficulty-> 2

Submitted by mikejuk
mikejuk (1801200) writes "A pair of computer scientists from the Babes-Bolyai University (Romania) and the University of Notre Dame (USA) have made some remarkable connections between Sudoku, the classic k-SAT problem, and the even more classic non-linear continuous dynamics. But before we go into the detail let's look at what this means for Sudoku enthusiasts. Maria Ercsey-Ravasz and Zoltan Toroczkai have devised a scale that provides an accurate determination of a Sudoku puzzle's hardness. So when you encounter a puzzle labelled hard and you find it easy all you need to do is to compute its , a co-efficient that measures the hardness of the problem. An easy puzzle should fall in the range 0 3 with the hardest puzzle, the notorious Platinum Blond being top of the scale with = 3.6. We will have to wait to see if newspapers and websites start to use this measure of difficulty. The difficulty is measured by the time it takes the classical dynamics corresponding to the problem to settle in the ground state and this depends on the degree of chaos in the search for a solution.

"...individual German Typhoons flew against single F-22s in basic fighter maneuvers meant to simulate a close-range dogfight.

The results were a surprise to the Germans and presumably the Americans, too. “We were evenly matched,” Maj. Marc Gruene told Combat Aircraft’s Jamie Hunter. The key, Gruene said, is to get as close as possible to the F-22 and stay there. “They didn’t expect us to turn so aggressively.”"

I don't doubt this report. However, my understanding is that the point of F-22 is to conduct its engagements at long-range and avoid these close-range knife fights. If the threat gets to dog-fighting range, the F-22s have screwed up and lost their greatest advantages.

But even for those few of us who claim to be complete skeptics, belief quietly sneaks in.

Nope. Not a bit of it. In my experience, only believers believe that everyone else must secretly be a believer. The rest of us live a fact-based life.

I agree with you 100%.

I'm a rationalist, I've convinced myself that organized religions are man-made for the enrichment of their power-brokers, I know that there is no evidence for an interventionist god in the modern world, and I'm am certain beyond a shadow of a doubt that astrology, crystology, pyramidism, and their ilk are without basis in fact.

Having said that, I will move heaven (ha!) and earth to ensure that I wear my lucky jockstrap when i suit up for the game on Sunday mornings.

Submitted by suraj.sun
suraj.sun (1348507) writes "Subnetting IPv6 sounds very complex but all you need to do is how an address is formed and how to efficiently use CIDR notation. An IPv6 address has 8 sections seprated by coloums and each sections has carries 4 hexadecimal digits(http://anuragbhatia.com/networking/how-to-subnet-ipv6/). So an IPv6 address is something like: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx – Each x can have a hexa decimal value i.e from 0 to 9 and a to f. This turns out to be 16 + 16 + 16 + 16 + 16 + 16 + 16 + 16 bits = 128bit, which means total possible addresses in IPv6 space is 2^128.

In most of cases RIRs like ARIN/APNIC allocate a /32 IPv6 block. This means first 2 sections 16+16 bits are reserved and rest 6 sections i.e 128-32 = 96 bits are available for use. Let’s pick example of Google’s block, 2404:6800::/32 from APNIC in Asia. Since only first 32 bits are reserved, block 2404:6800::/32 goes from 2404:6800:0000:0000:0000:0000:0000:0000 to 2404:6800:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF"

Submitted by

Fluffeh writes "Judge Holderman ruled against copyright holders who were trying to paint a rather distorted picture. They sue just one Internet user, but use that lawsuit as a pretext to subpoena other defendants who had participated in the same BitTorrent swarm. The plaintiffs in these lawsuits claim that the other users had participated in a "conspiracy" to assist one another in distributing particular copyrighted works. Because the copyright holder's threat is based on the cost of litigation (and risk of public embarrassment — as this is a tactic used increasingly by the pron industry) more so than the damages a defendant would face in the event of a loss, innocent defendants have virtually as much incentive to settle as guilty ones do. That's not how things are supposed to work, and more and more judges are refusing to play along. Coupled with recent rulings in Florida, the copyright holders seem to be finding less and less favour with judges."
