This shits me. This story is *huge*, all of a sudden the laws of physics as we know them may have to be rewritten and all anyone here had to say is asinine crap about Pi.
Maybe it should be "News for technically semiliterate social outcasts. Stuff that matters, trivialised."
And it's the same story for everything remotely scientific. Unless it's a story about 500 fps quake or the Microsoft boogeyman noone takes it seriously.
All I can think is to blame it on the horrendous state of American education, where most of the readership is drawn from (I assume).
ASIS stands for the Australian Secret Intelligence Service, essentially the Australian foreign spies. I'm not sure but I believe they have no jurisdiction to operate within Australia, but I might have that wrong. They are not, BTW, held accountable in any public forum, even Parliament (?!)
ASIO is the Australian Security and Intelligence Organisation. They are *only* allowed to operate withing Australia and I believe the article refers to them.
DSD is the Defence Signals Directorate, essentially a (much smaller) analogue of the NSA.
There's actually a legitimate phenomenon known as "quantum teleportation". Basically, if you share an entangled pair of qubits beforehand, you can send an arbitrary qubit state using only classical information from one place (where the first entangled qubit is) to another (where the second entangled qubit is).
As long as you destroy the qubit you're trying to send.
I also may be wrong, but I have the feeling that the relavant quantities here are also not the density on the chip and some function of the switching speed and the switching current. So while the transistor area may decrease by, say, a factor of 2, the switching current by a factor of sqrt(2) and the speed increases by a factor of sqrt(2), say. Then the heat given off would be proportional to the heat per transistor times the density, which will be the same heat per transistor as the old chip times double the density: so we get double the heat output.
This is all on the absolutely shady side of things of course, I'm assuming that the current is proportional to the linear dimensions of the transistor, so it goes as the square root of area, which is the relevant quantity when calculating density.
Also, I had to assume that heat is proportional to the switching current times the speed, and that the speed varies inversely with the current.
But the point is, it is conceivable that heat output would increase with decreasing size.
It was just on the news in Aus. tonight. There was a problem of some kind and it fell from the sky like the proverbial stone. Apparently the experiment it was carrying survived the crash though.
They might also be perfect for viewing Gamma-Ray bursters. The thing is, you need to turn to face bursters as soon as possible as they die away quickly. IANA Astronomer, but these dishes may be very useful.
You'd just need to get the message from the initial detection to the dishes quickly. I guess all that fibre'd help as well.
it's been absolutely horrible. I don't know why but what seems to be the root nameserver over here (ns0.telstra.net) has also been down. Perhaps it's actually located over in Palo Alto, where quite a few telstra servers *seem* to be. (BTW telstra is the big telco/ISP in Aus.) Don't quote me on any of this though, I'm not privy to any official info.
We had a similar problem earlier on in the year, as a matter of fact, when a farmer cut the fibre between Sydney and Melbourne with a backhoe. Luckily it was a private line and it only shut down the stock exchange(!?!).
The images on mathworld (or lack of them) are not really a problem. If you look at the source you'll see that every image has the formula it represented in ascii as it's comment.
...assuming, of course, we never progress beyond the current method of using optical transmission techniques. The speed-of-light
bound applies only to currently known transmission methods; I would not be the least bit surprised if, at some point in my lifetime,
a new method of transmitting data was discovered that did not rely on using light or electricity as a carrier for said data...
Bear in mind that a computer scientist from only 50 years ago would have laughed (wistfully) at the idea of fitting millions of
transistors into the palm of one's hand
These are very different things.
In one case (faster than light information flow) you have the ability to send messages to the absolute past.. In the other (transistors on chips) there is no obvious reason to rule it out.
I for one will be completely surprised if FTL communication ever appears, until I send a message back in time to myself telling me that it will happen. Then I won't be so surprised, so I won't bother sending a message back, then I will be surprised..........
Slashdot Mirror
Talking about the people involved, I have had both Victor Flambaum and John Webb as lecturers (I'm studying physics at UNSW).
John Webb told us that apparently he bumped into Victor on the stairs one day and they got to talking, that's where the collaboration started.
Interestingly, Victor is one of 4 russians in the theory department here. I think they emigrated from russia post communism.
Anyhow, just wanted to do some name-dropping...

that are fundamentally architected with a weak security
"architected"? WTF?

So, yes, it does sound a lot like star trek..

I think it's the D-21 or something. Anyway, the drone I'm thinking of piggybacks on the SR-71.
IIRC it's basically one of the SR-71 engines with tiny stub wings and a bunch of probes
about the Bungle Bungles. A rocky labdform in NW Australia. There's heaps of fluff, sure, but nothing of any substance.
All I want is some details but all I get is anecdotes from Swedish tourists and tour group advertising.
And maps, there really are no good map resources for the Australian desert.
I guess there is still a use for the public library after all.
Dr. Ng?? How do you pronounce that??
RTF Article
But Dr. Ng (pronounced ENG) has calculated...
It's qubit, not qbit.
Thanks:-)
speaking of registries, does anyone know how the windows regstry is stored? Is it in a plain file? If so which one; if not where?
And if you absolutely need a named server, run something that doesn't have a history of being cracked.
Like djbdns. See cr.yp.to for details.And while you're there replace inetd with tcpserver.

...science relies on the repeatable experiment as its' basis, and religion relies on articles of faith as its' basis.
jesus christ, are apostrophes so fucking hard.
its : belongs to it
it's : it is
Me too, from Australia. Got k5 and rootprompt fine though.
Weird
Including English it seems....

It's not pretty, but it's there

how about the definitions of angular momentum:
J x J = ih J
where J is the angular momentum operator: J=(Jx, Jy, Jz) and 'x' denotes the vector cross product.
For a state represented by the ket |jm>, we define j and m such that:
(J.J) |jm> = j(j+1) |jm>
Jz |jm> = m |jm>
For normalized kets labelled by distinct eigenvalues, the inner products are equal to 1 if the eigenvalues are the same, 0 otherwise;
and so on and so forth....
Dave
You should probably brush up on your spelling as well.
It's steganography.
sorry.

Good point
Enough dogma, for fucks sake.

yes. yes it is.
