Sure. I don't work in physics, but here is my understanding of the holographic principle.

Imagine that you are in a bathtub. There is a certain kind of physics that dictates the motions of waves in the bathtub. Now, you might believe that you need to understand the entirety of water to predict its future motion. You could develop a theory of water in bathtubs, and run experiments to verify if they are true.

After a lot of thought, you might come across the realization that in order to understand the mechanics of the water in the bathtub, it is only necessary to understand the way the surface of the water moves, or maybe even how the water interacts with the edge of the bathtub. This means that you've reduced the dimension of your theory in some way. While this analogy isn't true, there are examples of where it is-- for instance, the physics of harmonic oscillators, like strings, drumheads, etc, can be understood by looking at the boundaries of those oscillations.

Now, in physics, there are several ways that holography shows up. The most famous of these holography theories is called the AdS/CFT correspondence. It conjectures that a certain 5 dimensional string theory can be understood as a 4 dimensional field theory on the boundary. Now, I think that this perspective is interesting to physicists not because of the dimension change (dimensions in theoretical physics usually have little correlation with the observable dimensions of spacetime) but because it was one of the first known correspondences where a string theory reproduced the results of a field theory. Quantum Field theory is the most validated theory of physics we have, but it is thought to have foundational errors. String theory is suppose to offer a way out, but is... hard.

Hope that helps!

I simply googled a few lines from some of her other posts, and saw that has happened before. For Example googling "Michelle and their two-year-old daughter are dragged into the fray, the No" from her article http://www.longislandpress.com/2011/03/13/no-impact-man-screening-panel-discussion-march-13/ Pulls up a summary from this site, which was published months earlier. http://bkfreestore.tumblr.com/post/1336085827/no-impact-man-an-outdoor-film-screening-with-colin

The school has posted a message indicating that the Genesis system is down, but has yet to publicly acknowledge that a breach occurred.

Holy Hand Grenade of Antioch Provokes Bomb Scare 186

Bomb disposal teams were called in and a nearby pub evacuated after water company engineers mistook a Monty Python film prop for a hand grenade. After nearly an hour of examination by bomb experts, they counted to three. No more. No less. Three was the number they counted, and the number they counted was three. Four they did not count, nor two, except to proceed to three. Five was right out. Once the number three had been reached, being the third number, they declared that the grenade was actually a copy of the "Holy Hand Grenade of Antioch" used in the film Monty Python And The Holy Grail. A police spokeswoman confirmed that the device was a toy and that it had been no danger to the public.

(QUESTIONER): Vice President Cheney yesterday said that he expects that American forces will be greeted as liberators and I wonder if you could tell us if you agree with that and how you think they'll be greeted and also what you meant you said before that some Iraqi opposition groups might be in Baghdad even before American forces?

Is AMD Dead Yet? 467

Posted by kdawson
from the pining-for-the-fjords dept.
TheProcess writes "Back in February 2003, IBM predicted that AMD would be dead in 5 years (original article here), with IBM and Intel the only remaining players in the chip market. Well, 5 years have passed and AMD is still alive. However, its finances and stock price have taken a serious beating over the last year. AMD was once a darling in this community — the plucky, up-and-coming challenger to the Intel behemoth. Will AMD still be here in 5 years? Can they pose a credible competitive threat to Intel's dominance? Do they still have superior but unappreciated technology? Or are they finally old hat? Can they really recover?"
