/\ For when your only view is your ugly neighbours.

When I lived in St. Louis I and my roommates were the only three whites in a building with over a thousand apartments. One floor down there was a nice family who had windows like that because the "view" otherwise was brick and iron sixteen feet away across an alley.

In 1905, 115 years ago, British Engineers constructed the Victoria Falls Bridge linking Zambia and Zimbabwe. This was part of Cecil John Rhodes' mega-project of connecting Africa from Cape Town to Cairo via rail.

British Engineers had come earlier to assess the Victoria Falls gorge, survey, and take measurements, then designed the bridge based on the geology of the gorge and their measurements. The bridge was prefabricated in England and then shipped to Mozambique and transported to its current location from the Port of Beira by rail for assembly.

The assembly took only 14 months and it fit according to specifications -- 115 years ago, before computers were invented; all calculations had to be done by hand!

To this day, the bridge is fully operational carrying both trucks and cargo trains - 115 years later.

^^I suspect that in addition to hand calculations, those engineers utilized the slide rule. Extremely efficient rule users could compute trig and calculas functions as fast, if not faster, than the current calulating and adding machines available in the early 1900's

True enough. I still have my old slide rule around somewhere. In high school toting a "slipstick" was a mark of status. The one above is a basic "student" version; mine had additional scales for doing sine, tangent, square root, log base 10, and I think natural log -- all useful for engineering, of course.

Interestingly there are schools that still teach use of a slide rule.
