rennerik writes "Scientists at McGill University in Montreal say they've discovered a new state of matter that could help extend Moore's Law and allow for the fabrication of more tightly packed transistors, or a new kind of transistor altogether. The researchers call the new state of matter 'a quasi-three-dimensional electron crystal.' It was discovered using a device cooled to a temperature about 100 times colder than intergalactic space, following the application of the most powerful continuous magnetic field on Earth."

On a nerd side note. We all know Dilithium in reality is a gas. But at the temperatures stated in the article. Would it be able to form a solid? Likely it would NOT be a crystal but it'd be fun to know.

Intergalactic space is about 2 or 3 Kelvin. Getting down to 100 times colder than that - 20 or 30 millikelvin - requires a Helium 3 dilution fridge. Helium 3 is a rare (and expensive) helium isotope. Physics labs can afford this sort of equipment, but we're not going to be using the setup for gaming anytime soon.
Not to mention, the vacuum pumps, the cold trap and the helium storage system would probably take up most of the space in your cubicle anyway.

TFA doesn't state any specific temperature, but I find the analogy to how "cold" space is rather troubling. Space is really "warm", as it contains energy left from the Big Bang (although no one with a common sense would describe it that way in daily talk), and saying that something is so many times colder than space really just doesn't make sense. You can always compare sizes, but as heat is a positive size, because you can't have negative energy, you can just say "this is a hundred times hotter than that" or "my freezer is two times as cold as my refrigerator compared to my living room". The one who thought of this analogy could be talking about degrees on Celsius or Fahrenheit, but then those numbers must be way below absolute zero, or 0 Kelvin, as space is just 2.7 Kelvin, or -270.7 C ( http://helios.gsfc.nasa.gov/qa_sp_ht.html [nasa.gov] ) and taking for granted he is comparing the temperature of space to 0 ÂC, that means that those crystals are actually -27070 C. And _that_ would be some real frontpage material...
You seem confused. He speaks of "a temperature about 100 times colder than intergalactic space". Intergalactic space has a temperature of about 3K. It does not make sense to talk of degrees C, since C is not an absolute scale. 100 times colder than 3K is 0.03K.

It does not work well. 100x colder than 1 C is not 0.01 C, it is -270.27 C. And the reason people don't say 0.03 K is because the average person does not know what K is, but they know space is very cold.

One of the reasons the average person does not know what K is, is because they're never expected to know it.
If everyone stopped using Celsius or Fahrenheit in situations where Kelvin would better suited, people would have to actually remember the Kelvin-scale from school-physics or take a minute out of their lives to find out what the Kelvin-scale is.

Not a new state of matter at all (Score:5, Informative)
The researcher, Dr. Guillaume Gervais, is director of McGill University's Ultra-Low Temperature Condensed Matter Experiment Lab. There's nothing in the journal letter about "a new state of matter". The McGill Newsroom article quotes him as saying to the interviewer, "It's actually not quite 3-D, it's an in-between state, a totally new phenomenon" as compared with the 2-D electron crystals that transistors and IC chips are made of. The interviewer, or an editor, thought "Physics -- state -- new state of matter". Engadget's Melanson picked up the error and passed it on uncritically.
Moore's Law isn't just about silicon any more (Score:5, Interesting)
Since there are already numerous posts invoking the applicability (or not) of Moore's Law, I thought I would start over. Although Gordon Moore certainly formulated his law based on silicon (original is here: http://www.intel.com/technology/mooreslaw/ [intel.com].) it can be applied clear back to 1890 with the Hollerith 'computer' that tabulated the 1890 census. When you graph it out, Moore's Law applies to electro-mechanical switches, then to relays, then to vacuum tubes, then transistors themselves (like in a six transistor radio of the 50's), then on to silicon. It's still the same exponential curve, in five separate states, only the last one of which is silicon. Kurzweil discusses this in depth here: http://www.kurzweilai.net/articles/art0134.html?printable=1 [kurzweilai.net]. People who claim Moore's Law doesn't apply because this isn't traditional silicon acreage are missing the point, which is that not only is Moore's Law more encompassing than the originally envisioned, it is not going away any time soon. The imminent death of Moore's Law, as always, has been greatly exaggerated.

For any given particle, you can't know its exact position and velocity. Particles can never reach absolute zero because then you would be able to determine their position since you know their velocity would thus be zero given they have no energy by definition of absolute zero. An extension of that then is if you know a particle's velocity you will never be able to determine its position. If you can't determine its position you can't determine whether it is really outside a vacuum. You may be able to say it isn't in the middle of the volume which represents the vaccum but at the boundary you can't say for sure whether the particle is on the inside of the vacuum or outside. This is Heisenberg's Uncertainty Principle. An absolute zero temperature vacuum is definitely impossible due to the uncertainty principle.

Radiant temperature. (Score:4, Informative)
You don't need matter to have a temperature. Even in a "perfect" vacuum (i.e. nothing but quantum fluctuation transient particle-antiparticle pairs) there is still radiant energy in the form of photons - and their wavelength distribution corresponds to a temperature.
It's the temperature at which a black-body test object, bathed continuously in photons of that frequency distribution, would neither warm up nor cool down further.
The radiant temperature of the sky far from the influence of nearby galaxies is known as the "cosmic background temperature". It's about 4 degrees absolute - corresponding to the light from the big bang red-shifted down a LOT by cosmic expansion.

Re:Could you be any more vague? (Score:4, Informative)
According to wikipedia, intergalactic space is 2.71 Kelvin. I would assume that they mean "100th the temperature of intergalactic space", not "100 times colder than intergalactic space", as the latter is nonsensical and implies that it exists at 100 times colder than intergalactic space is colder than room temperature, meaning -28834 Kelvin (293 - 100 * (293 - 2.73) where we assume that room temperature is 20 degrees centigrade). This is nonsense.
I don't see a problem with "100 times colder than intergalactic space". Temperature is an absolute scale, like size. It's like saying that item X is "100 times smaller than a coin". You don't then compare the size of the coin (say, 0.01m) to the room (say 3m) and then complain that item X is not of size -296 (3 - 100 * (3 - 0.01)).

Let's say I have a temperature which is 100 times larger than 27.1 mK, this would be 2.71 K. Indeed 27.1 mK is smaller than 2.71 K and 2.71 K is larger than 27.1 mK. So saying 100 times smaller than 2.71 K should indicate I mean 27.1 mK. In no way is this nonsensical and I'm pretty sure everyone here understands that "X is N times smaller than Y" means multiply Y by the reciprocal of N, similarly "X is N times larger than Y" means multiply Y by N.
Granted this isn't something you'd see in technical writing, but I'm pretty sure Information Week isn't a technical journal, so why be a pedant about it?
