I for one am interested in a car that can self drive on freeways and would prefer to drive myself in town. It seems that freeways are a simplified problem, being easier to map (and update), no stop lights, no cross streets,... Hopefully the freeway self driver will be a practical target for the near future.
Had a friend who took 2nd in a core war competion due to someone else who took this kind of statagy. You could submit as many candidates as you like. The winner submitted a bunch who were identical except for one which had the "queen bee" flag set. The drones could determine when they were battling against the "queen bee", and if so, would go belly up.
Yes, seismic tomography has been around for at least 30 years. Around that time I remember seeing pictures of the Pacific Ocean plate being subducted under California. For an interesting article that places the current article in context, see
Plumes From the Core Lost and Found.
The story I heard was that 90% of the brain was support cells and 10% neurons, hence "we use 10% of our brain". After that, it got reinterpreted. Not sure if that's a fact...
Page rank, to a first order of approximation, ranks your page by "popularity". Using a voting system,it counts the number of links to your page.
To a second order of approximation, it weights the votes of the referencing links by their popularity.
To a third order of approximation, it is a Markov chain that measures the long term likelihood of you arriving at a page, if you to randomly traverse the net: taking random links out of a pages and occasionally take (1/20?) random jumps to arbitrary urls.
NP-hard: A decidable problem such that any NP problem can be reduced to it in polynomial time.
NP-complete: NP and NP-hard.
There DO exist NP-hard problems which are not NP. In fact, there exists an infinate ascending tower of classes that extend beyond NP (which are all NP-hard problems.)

Mammary glands to produce silk? Hmmm, must be ;-)
