Instead of employing the traditional trial-and-error method of self-assembly that is used by nanotechnologists and which is found in nature, Torquato and his colleagues start with an exact blueprint of the nanostructure they want to build.

Things that make you go hmmm....

Interesting, but we'll have to wait and see.That said, nanotech is incredibly interesting. Maybe in our lifetimes, we'll see the collapse of entire commodity markets because of the cheap nano-versions of certain things. That would be interesting.

"In a sense this would allow you to play God, because the method creates, on the computer, new types of particles whose interactions are tuned precisely so as to yield a desired structure," said Pablo Debenedetti, a professor of chemical engineering at Princeton.

About 250 years ago the average life expectancy was 35 years old. Humans started "playing God" many centuries ago.

Man already tried to play God once. It was called the Tower of Babel, and we know what happened there.

Re #1

Basically, this means that there is a search space of many possible configurations. Each configuration can be represented as a kind of potential well. Some well is deeper and wider than others, while others are narrower and smaller. Most of the time, we get the configuration with the deeper and wider potential wells. However, we love to get the configuration associated with a narrower and smaller well, which is hard to get to by randomly exploring the search space, which is what traditional method is about. You need to tweak the system in a certain way to push it into a desired well.

Still, this is hardly like building a house based on a blueprint. It is more like navigating a car, with a partially working steering wheel, into a desired pit, avoiding the biggest and widest pit and many others which you are not interested in.

It'll all go well until they try and unionize. Then, the bulldozers will be unleashed.

Great! Now we can have that transparent aluminum Scotty talked about. Or at least nanophase aluminum.

I notice the funding finally came from the Dep. of Energy..

Sounds like someone there is thinking clearly..
Consider atomic energy, and custom designed nuclear fuel rods, with a safety factor added by seperating uranium or plutonium atoms with something like carbon (or silicon) nanotubes..
Then consider those carbon (or silicon) nanotubes are constructed to have an inner diameter of say, the size of a hydrogen atom..
You could now feed hydrogen into a nuclear reaction on the atomic level... One hydrogen atom at a time.. ( with several billion individual hydrogen feeder tubes being controlled at once.. )
This could be a crude sort of fusion reactor..
The fission reactor providing an energy source as a "starter" much like a diesel engine..

A physicist could probably tear this idea apart in a couple of minutes..(seconds) but I will revel in my genius for the moment.. ;o)

Reading this reminds me of Dembski's "The Design Inference." Of course, this current version has as its primal source Man and not some Big Statistician in the Sky. But of course man sprang from nothingness via the big bang which itself was a physical anomaly since the galaxies or universe is and always was.

Concerning the genius of men..

I believe there is a feminine conspiracy..
I can't reveal it here, publicly..

But I call it, " Schroedinger's Wife "..

How about this stuff now?

A ceramic research lab in Dresden, Germany, has developed transparent Alumina by subjecting fine-grained (I'm guessing extremely fine-grained) aluminum to a whopping 1200 degrees Celsius ...the result of which is amazingly light but three times tougher than hardened steel of the same thickness, and it's see-through.

I wonder how expensive it would be, on a large scale, to simulate the atomic structure of pure gasoline?
