"Continuum" mobius loop at National Air and Space Museum.
"Infinity" mobius loop at Smithsonian National Museum of American History.
You can make a mobius loop by giving a strip of paper
a half twist and then gluing the ends together. The result is a one-sided
continuous surface--a topographical anomaly that has profound implications
for the structure of the extra-dimensional universe, higher order mathematics,
and advanced theoretical physics. Wow! After all that, paper seems a little
too cheap and flimsy to represent such a wonderful toy. If you want to
see some more permanent mobius strips, youíre in luck, because the DC area
has a few to offer. Each of these is pretty impressive, but as Clifford
Pickover notes in his book The Mobius Strip, ...many of these are thickened
variants in which the ëstripísí cross section is essentially an equilateral
triangle that is rotated 120 degrees along the strip.î Check out Pickoverís
book for more information about the history, implications, and cultural
impact of the mobius strip. Meanwhile, you can visit these sites:
1. ìInfinityî sculpture by Jose de Rivera from 1967, a
curiously curved chrome mobius strip located outside the National Museum
of American History on the Mall side of the building.
2. ìContinuumî sculpture by Charles O. Perry from 1976,
a double mobius strip with complicated curvature, is located outside the
National Air and Space Museum on the Independence Avenue side of the building.
3. In the plaza at the U.S. Patent and Trademark Office,
in Arlington, VA, thereís a snazzy red mobius strip.
