Yeah, I know. I use them. The TACC
machines here in Austin have up to 1024 cpus in parallel locally. Plus,
with infiniband, they are networked to other supercompus elsewhere.
>(Actually, it's been going on for many years.)

Millions? Hardly. You'd never be able to cool such a setup, even if it
is decentralised by infiniband, or whatever. Power
consumption vs dissipation would be too prohibitive. I don't
think we can go further than a few tens of thousands.
Actually, the issue here is computational power vs computational
demand. Even with all the power of parallel cpus, there will always be
folks who'd want to simulate a sizable fraction of the Earth's
atmosphere, or try to copy living systems into computer memory, or want
to figure out if tossing a coin is really a 50-50 probability of
heads-or-tails, or try to simulate phase transitions of 10^20 atoms, or
diagonalize 200-billion X 200-billion matrices. Eventually, no matter
how many cpus you add in parallel, you will fall short of the demand.
The only way to have virtually unlimited computational power is to use
the quantum properties of matter itself to process information.
Yeah, but that is the wrong kind of business model. It's reactionary, and typical of monoliths like Intel. Quantum Computing is not a nebulous theory, but a rapidly maturing field with thousands of research teams all across the academia. There are a few conceptual problems, like the Wigner Paradox problem or the classical coupling problem, but in the long run this represents the best possibility in the evolution of computing hardware. Wasting needless resources in cramming things into other dimensions (height) or closer together will only delay the inevitable, and when it comes, there will be no fallback, as there will have been no funding for QComp research, since they wasted it all in trying to fight back the laws of nature.
None of this is relevant in the long run. Eventually, chip manufacturers will hit the blank wall of the Heisenberg Uncertainty Principle. As you try to cram more transistors into smaller spaces (even in 3-D), you localize the electron wavefunctions (not to mention that cuttoff is achieved only if the electrons are in conduction bands, which will cease to exist if the transistors are too small). This means that they delocalise in Momentum space, and their Shannon entropy goes up, causing them to heat up drastically and eventually melt. Solid State Technology has taken us far enough, trying to stack chips will only prolong the inevitable. Researchers should focus on a fundamentally new method of computation, like using entangled Greenberger-Horne-Zeilenger states or Bell states for computational purposes.

AAARGHH!!! There is no such thing as relativistic mass! It's a
pedagogical fiction invented by Bergmann, Einstein's graduate student (I wish I could go back in time to whack him in the head, but I like his textbook). Einstein never mentioned any
$E=mc^2$ or whatever. The correct statement is that the application of
constant force does not imply constant acceleration in relativity.
(sorry, my latex2html isn't working for some reason)
\begin{eqnarray*}
{
F^{\mu}&=& \frac{dp^{\mu}}{d\tau} \\
F^{\mu}&=& \frac{d}{d\tau}\left[m
\frac{dx^{\mu}}{d\tau}\right] \\
F^{\mu}&=& m\gamma^2 \frac{d^2x^{\mu}}{d\tau^2} \\
\gamma^2 \frac{d^2x^{\mu}}{d\tau^2}&=& Constant\\
}
\end{eqnarray}
So if F is constant and $\gamma$ tends to $\infty$, then
$\frac{d^2x^{\mu}}{d\tau^2}$ has to go to $0$ to compensate.
See? not so hard to understand when you lay out the math, and
no need for al lthat relativistic mass increase crap. The only mass is
rest mass, that's it!

That's a good point. However, the claims made above are either cases
of priests screaming for the 4 horsemen of the christian
apocalypse, or the political rantings of Rabochy Put. They are made
with malicious intent in order to advance a political agenda. What I
said was a simple statement of fact concluded from social observations
and based on the dynamics of human interaction. They're not made with
any malicious intent.
And that is not always the fate of all societies. A few
cultures have endured for a long time, despite the vissicitudes of
history. This is primarily due to checks and balances placed on their
societies that prevent the dominance of a particular ideology. This has
not happened with the United States. One ideology has started to
dominate in their culture, creating a dogmatic society that can only
result in their decline and fall. There is nothing that can be done to
prevent this fall, but the effects and repercussions of that
destruction can be minimized.
Actually, in that respect, the United States is a lot more like the
erstwhile Roman Empire than the Third Reich.
Like the Roman Empire, the United States was founded on principles of
basic freedom by political visionaries. Like the Roman Empire, the
state was slowly lost to tyrants and murderers who used propaganda to
energize the masses with ideas of racial and religious superiority and
the concept of 'glory' or some abstract idea of creating a utopian
society. Like with the Roman Empire, this never actually happened. Like
the Romans, the United States started to decay with the growing power
of Christians in the State, while simultaneously engaging in acts of
excess and decadence as well as brutality towards those who chose not
to subscribe to their idealogy. If we carry the comparison to it's
logical conclusion, then, like the Roman Empre, this country is
inevitably destined to collapse in civil war and anarchy and invasions
from foreigners. In this respect, the Islamic zealots are a lot like
the Goths, Vandals, and Huns who periodically ransacked Rome during her
dying years. Like preying vultures and carrion crows, they sense the
eventual destruction of this country and are trying to get in on the
feast.
It's very sad that so many innocent people have to die before
this happens, but American Society has lost whatever virility and worth
it once had, and we should just let them pass into history and allow
their civilization a dignified death.
History never repeats itself, but historical situations often recur. I can only hope that wheatever comes after isn't worse.
There are infinitely many phases of matter. I don't blame you for this
misunderstanding. My chemistry teacher thought the same thing.
The thing is that a 'state' or phase of matter in itself doesn't mean anything. Phases are defined by the means of phase transitions.
A Phase Transition is perceived as a qualitative change in the
collective behaviour of a many-particle system. The phase transitions
we do understand are the ones that can be explained by the Landau
theory of spontaneous symmetry breaking of an order parameter. This
interpretation is sufficiently generic to include many material states
that can be called 'phases', like metals & insulators,
superconductors & insulators & metals, smectic
& nematic phases of liquid crystals and some really wierd ones.
Oh, and superfluidity & BEC are connected, they are
not 2 DISTINCT phases as such. Fermionic superfluidity is actually the result of Bosinic Cooper Pairs of Fermions.
Also,wrt to the posts that say that this is a high temp system,
High temperature doesn't mean high as in Fermi-temperature high. It's
still low enough for the comments above to be qualitatively valid. I
mean, 50 nanokelvin is still like a billion times colder than the
vacuum of intergalactic space, and the 'superfluid' is still a Quantum
Phase, that which has been achieved through a spontaneous symmetry
breaking of the many-particle ground state, which could never be
treated as a pure quantum state if the temp was THAT high. This is
fundamental.
fr
Temperature is not a scale of energy, it's a scale of
information. It's a parameter that determines the statistical
equilibruim of a system.
Temperature is related to energy, but that fact is a derivable one, not
one to be used in it's definition.
I'm not trying to be overtly pedantic. Just thought it bears
mentioning, that's all.
Also, the truth of the matter is that, since only long wavelength terms
matter in the immediate neighborhood of a phase transition (the ones
that we understand, anyway), the study of low energy systems carries
special importance over others, so that is one of the many reasons why
we cool things. In addition, we want to see collective behavior which
can be explained to a good degree by mappings into single-particle
problems (which, when you think about it carefully, are the only
problems that we REALLY can solve ab initio). This turns out to be very
interesting in systems where strong correlations and quantum
fluctuations dominate over thermal ones. With regards to this "new
state of matter" and similar works done by the Ketterle Group and
others, the primary advantage of these types of systems is their
"tunability", both in terms of their effective dimensionality
(controlled by lenticular magnetic traps that keep the energy gaps
above the chemical potential in totally trapped directions), and in
terms of the interactions, which, in this low temperature limit, can be
approximated by the long wavelength terms in the Born expansion of the
Lippmann Schwinger equation, ultimately leading to the possibility of
changing the nature of the interaction itself by tuning a homogenous
magnetic field close to a Feshbac resonance (the parent article
explains this better), or by using optical systems to control the
relative magnitude of tunneling terms over the "on-site" interactions.
We've NEVER been able to do that so well in any solid-state system
before.
That's why such systems are so vital to out understanding of condensed
matter physics, because we can do many things to it with relative
ease.
Heh, reminds me of a joke...
A poultry farmer was puzzled by the fact that his chickens were dying for no apparent reason, so he called in a Biologist, a Chemist, and a Physicist to try to figure out what's going on. The Biologist took samples of blood and other bodily fluids from the chickens, made slides, studied them under a microscope, but found nothing awry. The Chemist did various qualitative and quantitative chemical analyses on the samples to look for any problems, but found none. Finally, all eyes were on the Physicist who, after spending a few minutes in deep thought, suddenly got very excited and started to scribble notes on a page. After a few more minutes, he shouted out "YES! I've solved it! I know what's happening, but it only works for spherical chickens in a vacuum at absolute zero."
OK, great! I'm so happy.
