[SML] OT: Everything You Know About Faraday Cages Is Wrong

[Drew McCarthy]

"Now Feynman is a god, the ultimate cool genius. It took me months, a
year really, to be confident that the great man’s analysis of the
Faraday cage, and his conclusion of exponential shielding, are
completely wrong."

It turns out that the *thickness* of the elements of the wire cage are
more important than the spacing, which explains why parking garages
are often better Faraday cages than elevators.

The moral of this story: if everyone assumes that there's a good
theory for something, but nobody can actually find it worked out in
detail, there's a good chance that there actually isn't one.
