I wrote the whole of the bible and shakespeare on a neutrino. But I can't remember where I put it.
Imperceptibly tiny news from the world of nano-publishing today, as a new record has been set by American scientists for exceedingly small writing. Boffins at Stanford University say they have managed to write "SU" in letters smaller than atoms. "We ended up with the smallest writing in history," says Hari Manoharan, Stanford …
Is nobody else at all concerned that the first thing written with this super-duper new technology was SU?
It's not even in use and their trying to crack into systems using it by implementing the switch user command directly into the storage medium???
From the sounds of it though, they can store information in a subatomic space by manipulating the space around it: that's like saying that I can park my car in a 2ft x 3ft parking space, providing I have the entire car park to myself.
Don't get me wrong, it's a great advancement, it's just not as useful as they claim at the moment.
I am puzzled by this article. The information appears to be is stored in the arrangement of the C02 molecules not electrons. I think the electrons are the means of retrieving the information given the size of one co2 molecule is probably at least 0.3 nm this appears to simply be the unremarkable observation that electron interference patterns can be sub atomic in size.
It would be nice if there was a link to a paper or sonmething so we could see if this ws anything more than self publicity.
"From the sounds of it though, they can store information in a subatomic space by manipulating the space around it: that's like saying that I can park my car in a 2ft x 3ft parking space, providing I have the entire car park to myself."
Yes, except that in the same space they can store multiple bits by varying the electron wavelength. Which is more like saying, "I can stack 50 cars in a 2ftx3ft parking space, providing I have the entire car park to myself". (50 being a number i randomly picked from the clear blue as a smallish car-park). Whilst you still need the large amount of space, you can store more information like this than you would have done if you had used all of the space for lining up atoms.
@ whoever said 0.3nm is not subatomic, agreed, partially, it's 3 Angstroms, which isn't smaller than say, a helium atom, but is probably smaller than most atoms. Although you should never classically measure atoms, Heisenberg and all....

The short of it: the simultaneous encoding of the letters S and U requires an area a bit under 12.5 x 12.5 25 square nm. The letter S is encoded in 8 bits, so we'll assume the U is a comparable number.
This means that using an encoding region of 157.5 square nanometer, the average bit density for this region is 157.5/8 = 1 bit per 19.7 square nanometer. However, two letters were simultaneously encoded, so the virtual bit density for this area is actually 157.5/16 = 1 bit per 9.8 square nanometer.
In order to get to a virtual bit density of one bit per 0.3 square nanometer, at least 32 holographic layers per encoding area would be required. To justify the article's claim that they can "achieve information densities in excess of 20 bits [per square] nm", close to 200 holographic layers would be required.
The problem is the article, indeed, only looks at its readout area: a region measuring a mere 2.9 by 4.3 nanometer, which is then falsely considered the encoding region, measuring only 12.5 square nanometer. This introduces an order of magnitude worth of error in the numbers (getting from there to an encoding density of 1 bit per 0.8 square nanometer, and pushing that down to 0.3 with three or four more holographic layers is trivial, but also highly incorrect math).
The whole point about holographic anything is that the ability to retrieve the information depends on the relative positions of everything, including your measurement aparatus. It is therefore *not* unreasonable to include the size and complexity of the STM in the density computation. The information simply isn't *solely within* the microscope recording medium.
And as for the many coloured cars idea, I think you'll find that very similar colours require very high fidelity equipment to distinguish them. TANSTAAFL.
...but a mere single quantum level removed from this remarkable NeusTech. From here where I sit, one can for all intents and purposes plainly see (for lo and behold, I have made mese'f very small today) exactly as many holy angels as *want* to do so, just a-dancin' on the head of that hospitable host pin's head.
Lovely sight; lovely song too. (Full quad stereo and then some). Most excellent company indeed, all in all. Tea?
Tiny Dancer Paris. Of course, she isn't really /that/ small. But I rather expect Her Angelick Divinity dances right lovely anyway, even while holding the very pincushion of recent connoted reference ever so lightly, brightly and with full evanescent beauty in her tiny lovely rhythmically undulating hand. (Aahh-h-h. Nice.)
So what do angels dancing on the head of a pin actually wear? Try a spot of this very nice tea, and see!
