A portion of Nat Geo's press release:
Using the world's fastest high-resolution camera housed in a mobile trailer, Tim Samaras hopes to be the first to photograph the micro-second event (not visible to the naked eye) that triggers a lightning strike. Through this, Samaras hopes to discover clues to some of lightning's biggest mysteries: Why will a lightning bolt sometimes strike a low tree when right beside it is a tall metal tower? And why, for that matter, does lightning strike at all?
He is used to having people tell him that what he’s trying can’t be done. But before he became obsessed with lightning, Samaras spent several years chasing after tornadoes to deploy electronic probes, mounted with video cameras and other instruments, to record what it looks and feels like from inside. People were dubious about that too, but he managed to gather some of the most accurate readings ever of wind speed, barometric pressure, temperature, humidity inside a tornado vortex.
Congratulations, Tim... As always, great work!
