I recommend Computer Science Logo Style by Brian Harvey, one of the best CS instructors at UC Berkeley. You can get the books for free here (scroll down a bit).
I was under the impression that gotos are actually the best way to express certain types of computations, such as finite state machines. (Mutually recursive functions would be better, but most language implementations don't optimize tail-calls.)
There are more air planes in the sea than submarines in the sky. Only because of gravity. I'm sure there are plenty of wrecked submarines under the sea, too.
This sounds a lot like the cellular morphing robot technology introduced in Isaac Asimov's Robot City (which predates Stargate by one or two decades, I believe).
I didn't RTFA, but I wonder if the guy's work is related to an old artificial life simulation called Boids. The developer of Boids was able to model the flocking behavior of birds by formulating some relatively simple rules. When I first learned about the program, it sounded really neat, and according to Wikipedia it's still used in computer graphics to model flocking behavior.
Regarding porcine valves, the doctors told me that they're tanned, so I assumed that they'd be leathery. The doctors also mentioned off-handedly that they last about 5 years, but maybe I'm misremembering. (The time of my operation was 2001.)
I've had a valve replacement myself, and I believe there are two problems:
(1) pig valve: those are basically like leather, and they wear out after 5 years, requiring replacement even in adults. And open heart surgery isn't normally something one wants to have on a regular basis.
(2) artificial valve: blood clots form on them, requiring the patient to take anticoagulant drugs for the rest of his life.
