First, the study I'm talking about was work, not something I was pursuing on my own time. I talked to my wife about it because it's always intellectually interesting to see mathematical processes and models applied to business. It's a very efficient market. You need these types of tools to beat it. If that makes me an academic or pedantic, then fine, but it will also make a lot of money. It was exactly that interest that was my segue from McK to managing money.
As far as the 007 movie, yeah, actually we just saw it last night after work. I'm not much of a fan of Pierce Brosnan, but the movie was pretty good, except for the part about them swimming out of a submarine that's vertically in the seabed. Those things are easily 300 feet, so it's 10 atmospheres down there, then he swims up to the surface? His word of advice, exhale as you go up. Yeah, forget decompression limits.
As a total aside, does anyone know if submarines internal ambient air pressure is elevated or does it stay at 1 atm? |

after the Annapolis I served on a 688 class sub. subs don't operate an an elevated atmospheric pressure. the integrity of the hull is maintained structurally. if the pressure fluctuated, then the whole sub would act like a hyperambic chamber, causing the crew to have to limit manuevers the sub could take in times of war. you wouldn't want this. you want to be able to dive when you need to dive and surface when you need to surface. so, without an external air source if you to inhale air at one atmospher and then step into a dive chamber and push the pressure up to 5 atmospheres, you'd all of a sudden have about a fifth the air in your lungs that you started with.
