Moebius strip riddle solved at last

BigLug writes: "In a study to appear in Nature Materials, two experts in non-linear dynamics, Gert van der Heijden and Eugene Starostin of University College London, resolve the Moebius Strip algebraically.

From the ABC (Australia):

What determines the strip's shape is its differing areas of "energy density," they say.

"Energy density" means the stored, elastic energy that is contained in the strip as a result of the folding. Places where the strip is most bent have the highest energy density; conversely, places that are flat and unstressed by a fold have the least energy density.
