shinkansen to Kyoto

8:50pm JST Thursday 17 December 2009 (day 14512)

On the shinkansen, closing in on one hour aboard. We're zoooomin' along, but can't see anything outside really (cause we're in a tunnel, and) it's nighttime. To get a rough estimate of our speed, I note that it takes about 4 seconds for an opposite bound shinkansen to pass my window. If a shinkansen is 100 meters long, that's a combined speed of 100/4 meters per second, or 25 m/s * 60 s/min * 60 min/hour * 100 cm/m * 1/2.54 in/cm * 1/12 ft/in * 1/5280 mile/ft = 55.9234073013 miles per hour!

I think the arithmetic is correct, so it appears one of my estimates is off. If it takes 3 seconds to pass, then 74.5645430684 miles per hour. Hmmm still not fast enough.
