...bius Strip. Some of the book's 14 pieces, nearly half of which have previously appeared in magazines, were designed for what is currently called mixed-media performance. To begin with, there is a do-it-yourself Möbius strip that reads (when cut, twisted and joined as instructed): "Once Upon A Time There Was A Story That Began Once Upon A Time There Was A Story That Began . . ." It could go on indefinitely, though once around is enough for anyone to get Barth's point about the cyclical nature of storytelling-or yarning, as he would...
...finished work is designed to revolve once every eight minutes and is powered by a hidden ¼-h.p. motor whose reduction shaft is embedded be low its 8-ft.-high triangular base. In mathematical terms, Infinity is based on the Möbius strip, named for the 19th century German mathematician A. F. Möbius. It consists of a loop twisted on itself so that it contains one continuous edge and one plane. As the great form revolved majestically for the first time last week, the early spring sun glinted off its evolving planes, creating an impression of perpetual...
...bius loop can be made by cutting a harrow strip of paper and gluing its ends together after giving the strip a half-turn. The loop that results has peculiar qualities. Most important, though the paper it is made of has two sides, the loop itself has only one surface. This can be proved by drawing a pencil line down the middle of the strip. The pencil line covers both sides of the paper and returns to the starting point without the strip's being turned over. When cut along the pencil line, the paper forms not two loops...
Double Passage. Davis made a Möbius loop out of a strip of nonconducting plastic that had metal foil bonded to both sides to serve as an electrical resistance. He attached wires to the foil on opposite sides of the strip. When he sent electrical pulses through those wires, the current divided, flowed in both directions through the foil, and passed itself twice. Because of the double passage, the inductance was as low as Davis had hoped. He is delighted but still puzzled. The pulses apparently pass right through themselves, and he cannot be sure...
