Where Does Lightning Strikes Twice?

Contrary to folk wisdom, lightning does strike twice in the same place, and may even strike as many as ten times in a single spot!

Successive photographs of lightning flashes have been taken by engineers of the General Electric Company during electrical storms in the Berkshire Mountains of Massachusetts.

One can get an appreciable shock from an ordinary electric socket in a house wired at a voltage of 115. A single flash of lightning has been estimated to carry a charge of 100 million volts.

The heaviest weight ever lifted by a human being is 6,270 pounds, accomplished by Paul Anderson at Toccoa, Georgia, in 1957.

The 5 foot, 10-inch strongman, using his back, lifted a table loaded with a lead-filled safe and heavy auto parts. The weight of the objects equalled that of a 33-man college football team!

Elektro, the mechanical man, was made by the Westinghouse Company, and first exhibited in New York City during the World's Fair of 1939-40.

The seven-foot, 260-pound robot was set in motion by vibrations of the human voice. He could walk, smoke, count on his fingers up to 10, tell whether an object held before him was red or green, and perform 20 or so other feats.

Elektro's electrical system contained 24,900 miles of wire, or enough to encircle the globe.

The first portable timepiece was made in Nuremberg in 1504 by Peter Henlein.

Because of their shape and heft, these early watches were called "Nuremberg live eggs." The first wrist-watch appeared as early as 1790.

It was made by Jacquet-Droz and Leschot of Gene' a.
