Because Nature Isn't Classical

Via the Computational Complexity (welcome back Lance), the list of accepted papers for CCC 2008 has been posted. Woot, that's a lot of quantum inspired papers. By my count 7 of 33. Quoteth Feynman

...and I'm not happy with all the analyses that go with just the classical theory, because nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical...

Jennifer Ouellette was inspired by the recent book "meme," and is putting together a similar list of pop-science books. It might surprise some people, but I haven't been a big reader of pop-science books over the years. In fact, I've read few enough of the books on her list that I'm only going to…
We're at that time of year where people publish lists of top stories of the year, but as many crazy people will be happy to remind you, this Friday marks the end of another calendrical period, in the Mayan calendar. So, I'm going to steal an idea from a college classmate on Facebook, who wrote:…
In the building where I usually work, there are four doors on the ground floor. The main front door, that I usually exit during the day; a back door that I usually enter and leave at the ends of the day; and a left and right side door. The door to the left leads to a parking lot, with no sidewalk…
A bunch of people have sent me links to an article about MapReduce. I've hesitated to write about it, because the currently hyped MapReduce stuff was developed, and extensively used by Google, my employer. But the article is really annoying, and deserves a response. So I'm going to be absolutely…

Quoth Mattuck regarding progress in calculating things (exactly):
"It might be noted here, for the benefit of those interested in exact solutions, that there is an alternative formulation of the many-body problem, i.e., how many bodies are required before we have a problem? G. E. Brown points out that this can be answered by a look at history. In eighteenth-century Newtonian mechanics, the three-body problem was insoluble. With the birth of general relativity around 190 and quantum electrodynamics in 1930, the two- and one-body problems became insoluble. And within modern quantum field theory, the problem of zero bidies (vacuum) is insoluble. So, if we are out after exact solutions, no bodies at all is already too many!"

If nobody know of what consist quanta it don't means, that nature isn't classical. And if you want to do simulation of nature you need nature itself, instead binary 0 dimension computer.
