Small world. I tried to watch that same movie last night but had to turn it off as the dam youtube commercials were like every 10 minutes.

Love the slide rule the designer used to design it

Did you note the precision of that designer's Slide Rule?

Tip: The length of the slide rule = precision. Accuracy is the visual repeatability.

Jim...

PS: I still have a vest pocket slide rule. 5"
PSS: longest Slide rule...
It measures 352 feet long, weighs 300 pounds and takes three men to slide. Skip Solberg and Jay Francis said it will calculate to "six significant digits," which apparently is a good thing. Some other engineers smiled and nodded when hearing of the "significant digits."
