The Los Angeles Times this morning (Sunday May 26) has an image of
the circular slide rule for calculating effects of nuclear bombs. It
is part of a collage to illustrate the lead item of the Opinion
Section (page M1), an article comparing current US foreign policy
with cold-war era policy.

The image is in authentic color (white and blue-green) and full-size
(5.125" diameter), but not fully legible, although the main label,
"Nuclear Bomb Effects Computer" is quite clear. It is very similar
to one in my collection, but is blank at a position on the rim where
mine says "Designed by the Lovelace Foundation".

Related question: The notation on my specimen is the only thing I
know about the Lovelace Foundation -- plus the assumption that it was
named for Ada. Does anybody have more information on that Foundation?
