Boeing 787 and the iPhone 3GS

The Boeing 787-8 Dreamliner is a superefficient airplane with new passenger-pleasing features. It will bring the economics of large jet transports to the middle of the market, using 20 percent less fuel than any other airplane of its size. The specs for the lower deck of the 787 suggest a capacity of 4400 cubic feet. The iPhone 3GS has a volume of 5.184 cubic inches and a weight of 4.8 ounces (i.e., 27.778 iPhones/cubic foot), thus it is possible for the 787 to carry as many as 122,000 iPhones. Interestingly, the iPhone is less dense than freshly fallen snow, which weighs in at 10 lbs per cubic foot.

Evacuation Patterns - Hurricane Katrina

I'm helping colleagues on a project that surveyed residents about their evacuation plans in the face of another large hurricane. Using a combination of PHP and Google Maps, I was able to plot the locations of survey respondents and one of the hypothetical tracks used in the survey. The underlying data is being used to analyze factors that might affect evacuation patterns. One of those factors is a distance-based measure: the distance from landfall, and the distance from the track itself. Preliminary analysis suggests that distance to landfall is a significant factor, yet distance to track is not.
