Very Likely Duplicate Sighting

PBS presentation on the Golden Gate Bridge

Charles Ellis (apparantly the chief number cruncher of
many large volumes of stress etc of the entire Golden
Gate Bridge) appears with two slide rules. They only
appear for a few seconds. I would be no better if
they appeared for a few minutes. One looked like an
8 inch circular Gilson Binary. The other most likely
a vintage K&E 408x?. I make no claim to recognize any
by sight. Joseph Strauss and Leon Moissieff got credit
for designing but Charles Ellis did the heavy lifting.
They shot the bear and he pulled the trigger.

RE: Electronic Calculators - Only after repetion becomes
drugery and prone to mistakes.
Slide Rule - Same plus use of log/trig/etc tables
become drugery also and should be relegated to need for
greater accuracy

Classic Euclidian Geometry - Geometry IS logic - Trig/computation
is math - I do not associate Geometry together with math -
NO WAY, NO HOW - Some imbecile needs a bolt of lightning -
