Re: [TCML] Lichtenberg on TV

On the CBS network television show A Gifted Man (Friday night 1/6/2012) the storyline featured a young boy with a perforated eardrum. Upon removing his shirt to check for other injuries there was a prominent Lichtenberg pattern on his back. I immediately said to my wife he was hit by lightning. The doctors on the show were puzzled and searched online to reach the same conclusion soon after.
My astonished wife said how did you know that before the doctors? So I related a story of several Rochester Teslathons where Bert Hickman made and sold Lichtenberg figures in various acrylic forms and I have several on display in my office cubicle. They are also viewable at his Teslamania.com website.
Anyway the episode should be available at the cable tv on-demand or network websites or hulu or elsewhere on the interweb by now.
I had a similar experience at a family gathering where one of the guys
was an ER physician, and he had some journal with a "what causes this?"
mystery puzzle in the back. It was the photo of a man's back with a
great Lichtenberg figure on it, prompting speculations about some sort
of weird dermatitis, or a surface skin infection that had spread.
I saw and instantly said, Lichtenberg figure, he was hit by lightning.
That's what it was, of course.
Here's a TC list question about which I've been wondering... Would such
a figure occur with an ordinary HV incident (e.g. contact with a power
line). Or would it have to be pulsed power with very high peak
current/voltage?
Lichtenberg figures are similar to the dendritic treeing that occurs in
dielectric, but not from the same cause, as far as I know (and treeing
is a long duration aging kind of effect), although the fractal nature IS
similar (and for the same reason.. field distributions)
