May God Bless and deliver safely our brave men and women who at this very moment are laying their lives on the alter of freedom so we may live without fear!. The Star Spangled Banner, like you've never heard it by Smittys Place. Watch it on MySpace Videos.
Narrator: Unlike Strauss, Ellis's ambition lay not in the glory of fame, but in the pure challenge of calculating every engineering detail.
John van der Zee: The bridge is like a gigantic math problem. And he had the mathematical skills to implement it. This was, in effect, 10 and a half volumes of pre-computer higher mathematics, done by one man, using a circular slide rule and a hand-cranked adding machine.
building the Golden Gate
By a Fault Line
California's ominous San Andreas Fault slashes from north to south through the Bay area, passing the Golden Gate a short distance out to sea. How would a bridge across the Golden Gate fare in an earthquake? Charles Ellis sounded a confident note in a 1929 lecture to the National Academy of Sciences:
"If I knew that there was to be an earthquake in San Francisco tomorrow and I couldn't get into an airplane and had to remain in the city, I think I should get a piece of clothesline about 1,000 or 2,000 feet long, and a hammock, and I would string it from the tops of two of the tallest redwoods I could find, get into the hammock and feel reasonably safe. If this bridge were built at that time, I would tie me to the center of it, and while watching the sun sink into China across the Pacific, I would feel content with the thought that in case of an earthquake, I had chosen the safest spot in which to be."
