It's a little over 2W. (2x 1.5V cells and a 4.3 ohm resistor).

No, can't read sh1t.
But thanks for the Cliff's notes.
So, the folks who predicted two centuries ago that there was something (which they called Ether) filling up what we call space vacuum today was right?

I wasn't able to read it either but from what cowmoo is explaining i believe that it has to be a substance similar to ether that acts as a medium in the air. Now obviously ether back then was undefined anyways so they may call this ether as well, but it's most important property is that within the superconductive world theory proposed by the scientist, it is necessary for ether-like substance to be present. I am still trying to comprehend how come however. What does super conductivity have in relation with "ether"?

On my phone and probably won't have a computer all weekend so TL;DR: Interactions between quark/anti-quarks is self-sustaining, just like electromagnetic interactions in a classical superconductor, which would lead us to believe the grid in which they're interacting is some sort of superconductor. The standard model is based upon this assumption. In order for that to be true it requires that a physical medium exists in which the interactions can occur.

Storing images in a field of gas
http://www.kurzweilai.net/storing-sh...quantum-memory
Quote:
Researchers have been able to store a single image in a cloud of rubidium atoms for several years. Now they've gone a step further by storing two images at the same time, Technology Review Physics arXiv Blog reports.

One of the enabling technologies for a quantum Internet is the ability to store and retrieve quantum information in a reliable and repeatable way.

One way to do this involves photons and tiny clouds of rubidium gas. Rubidium atoms have an interesting property: a magnetic field causes their electronic energy levels to split, creating multiple of new frequency levels (the Zeeman effect).

Switching the field off returns the atoms to their normal state and causes them to emit the photons, allowing the information they hold to be retrieved.

That immediately suggests a way of building a quantum memory: storing an entire image, sent into the gas by placing an image mask over the beam.

The storage lasts for tens of microseconds and the image can be retrieved with accuracies approaching 90 per cent. (The storage duration is limited by the movement of the atoms in the gas which blurs the images over time.)

World's shortest movie?

Now, National Institute of Standards and Technology researchers have stored two images, of the letter T and the letter N, in gradient echo memory (GEM) in an atomic vapor. The sequence of pictures above shows the images being released from the gas, as recorded by a high speed camera in 100-nanosecond frames.

"We have demonstrated that multiple images can be stored and retrieved at different times, allowing the storage of a short movie in an atomic memory," the researchers say.

Until now, sequences of images have only ever been stored at the same time in solid state media, such as holographic memories. The new technique seems to have impressive potential as a quantum memory device.



Zach, you should find this interesting. They've developed a way to create a folded box that folds itself. The cool thing here is that it can be scaled down to make nano-scale 3D structures. The process is surprisingly simple.

Good news for electric cars

For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless.

You lucky fvcking bastards. There's one that'll be over KY in a couple years. IIRC I looked 10 years out and that's as close as I'll be to one.

No love for SoCal, either.

I read a while back that NPS is doing viewing activities at Bryce among other places. Probably be awesome to see from that altitude. Hope those folks have good weather.

How long before our bodies are obsolete? This some science-fiction sh!t coming true. I was watching a special on Steve Jobs last night and they mentioned how he was obsessed with hands and was convinced our hands are the ideal way to interface with technology. I think mind control is the next evolution of that idea.
