I don't think the assumption was that the universe "solves" the equation to "compute" reality. Rather, I think the point was that the "breakdown" of quantum behavior into macroscopic behavior seems to happen around the same scale that the interactions described by Schrödinger's equation start to run into fundamental limits of computability in the form of the Planck Length, and that this can help "explain" the transition to macroscopic behavior as simply being the point at which the system becomes too complicated, in a fundamental complexity theory sense, for Schrödinger's equation to accurately describe it any longer.

Yeah, for the most part TMO has really great customer service and plans. But coverage depends heavily on your area. I live in Gainesville, FL and I get "3G" coverage that caps out at around 750Kb at full bars, and much of the city doesn't have coverage at all. When I was in Austin recently, tho, I was getting upward of 4Mb rates. I think they're much better on the west coast. I really wish it were not the case, but I will probably have to give up my N1 and switch to another carrier with decent data rates and coverage here.

If NASA times it just right, we could put people on the moon, launch the moon at Mars and have people walking on Mars just months later.

...

Next, we use the tide from the sun to travel to Alpha Centauri.

Wait, are you suggesting that we ride the sun to Alpha Centauri, or put kites in the tides on the sun caused by Earth and launch Earth toward Alpha Centauri?

Gaming With GPS On Your Smartphone 43

Barence writes "If your handset doesn't get you out and about, tramping through mud, climbing around and hunting for hidden treasure, then something needs an upgrade. The iPhone, Blackberry's Storm and Bold lines, and many Symbian and Android handsets, now sport GPS, which makes your smartphone the ticket to join a global movement of outdoor games. These are outbound challenges that pit teams and solo players against themselves and each other in the search for hidden treasure, undiscovered landmarks, and hidden spots all over the world. This article delves into several of the best smartphone-friendly real-world games, each of which is a bridge between the online and offline worlds."

No, I'm not saying every system would die within two weeks without maintenance, but enough of them would that it would create som real freaggin' huge problems! Not to mention the user's need to be led by the hand through the nigh unfathomable maze that is finding files you've saved, finding the right icon to click to launch the application you use every day, sending e-mail, etc.

It occurs to me that this points to most IT systems (particularly interfaces) being poorly designed.

Over the past 10 months, five feet have been found on shorelines along the Strait of Georgia, southwest of Vancouver. ... Four of the feet are right feet. The fifth is a left foot. ... There are more than 2,000 people missing in British Columbia alone, says Ebbesmeyer, so there's a good likelihood that they come from one of them.

One of the missing people had 4 right feet and a left foot? And I thought I was bad at dancing...

I find this a better analogy:

Picture a rubber sheet with a grid of parallel lines drawn on it. These lines represent the trajectory of objects moving along straight paths. An object with mass causes the sheet to shrink in toward the object in all directions, causing those parallel lines to curve in toward the object as well, and consequently the paths of traveling objects to curve in toward the object as well. (The stretch [pun intended], of course, is that the traveling objects are constrained to follow the lines, but you have to realize that the objects are not rolling along on top of the sheet, but are in fact moving within it.)

Extend this to three dimensions, and you have gravity. Now the only thing to determine is why objects warp space, and that is beyond my ken.
