The epicenter was at 31.084°N, 103.267°E, in Wenchuan County, Ngawa Prefecture, 90 km northwest of Chengdu, Sichuan, China, with its main tremor so far occurring [...]
In the last few days my interest has been captured by the world of life-streaming. After a few days of nosing around in various online sources I have discovered that we seem to be in the middle of a whirlwind of activity in this area, so it seems like an opportune time to look at [...]
Basically, maglev (magnetic levitation) trains work by switching the magnet in front of a train to one that attracts the train seconds before it reaches that point in the track.
