Spacetime is by no means a flat plane with a fixed notion of distance. It doesn't matter how far apart points A and B were, warp drive simply makes the necessary corrections to the universe such that there is a shorter path to get there. For example, we can see galaxies which are 46 billion light years away. Those stars "warped" to their current locations in a mere 13 billion years. Nothing FTL about that. The question isn't whether spacetime is malleable, it's whether there is any practical way of doing it.

Interestingly the one thing that LTE doesn't inherit from WCDMA is the CDMA-based air interface. LTE uses OFDM, which is a radical departure from CDMA. OFDM uses a drastically slower symbol rate to reduce the effects of echoing (multipath), but then makes up for the reduced capacity by adding thousands of narrowly-spaced carriers. Because combating multipath is the main limiting factor in practical wireless the overall efficiency is drastically increased.

I'm getting tired of hearing that load on here everytime some company does somethign disgusting.

corporation 1. an association of individuals, created by law or under authority of law, having a continuous existence independent of the existences of its members, and powers and liabilities distinct from those of its members.

Where does it say they can't have morals? A corporation has to obey its shareholders- mostly people who are just trying to save money for retirement through mutual funds and would probably be outraged if they knew they were abetting this crap.

Actually in the future scientists predict that long strands of aluminum could be used to transport electricity from areas where electricity is being generated to areas where it is in demand. They may even invent devices which can store electricity for later use! As for corn, you did a rather good job of explaining why corn is NOT a form of renewable energy.

The only reason nonrenewable energy is economically competitive is because we're borrowing against our future to pay for it.

The summary sucks. But I think the TFA argument is basically that based on the measured levels of contamination, the water is somehow getting from the magic rocks to the ocean. Perhaps the pressure vessel breached from a meltdown, and the containment vessel was cracked in the hydrogen explosion or maybe even the earthquake itself.

On a side note, while even in light of this fiasco I still think nuclear is safer than say, offshore drilling or coal mining, why do we continue to bother with anything besides renewables?

When people think of intelligence, they think of things that set a more intelligent person apart from a less intelligent person. This is dangerous in AI because it makes it easy to dismiss monumental achievements in intelligence that even an idiot makes look easy. Does Watson understand geography or human anatomy? Apparently not. But it does understand on some level that "the answer to this question is a city" which is a huge leap in intelligence.
