Playing with moebius strips

Some of these can be smoothly modeled in Euclidean space , and others cannot. For example, see Figures , , and of "Geometry and the imagination". If the strip is cut along about a third of the way in from the edge, it creates two strips. If all symmetries and not just orientation-preserving isometries of R 3 are allowed, the numbers of symmetries in each case doubles. It may be constructed as a surface of constant positive, negative, or zero Gaussian curvature. Yet this version of the stereographic image has a group of 4 symmetries in R 3 it is isomorphic to the Klein 4-group , as compared with the bounded version illustrated above having its group of symmetries the unique group of order 2. Retrieved from " https. This page was last edited on 18 February , at Cutting this new, longer, strip down the middle creates two strips wound around each other, each with two full twists. The other is a longer but thin strip with two full twists in it — this is a neighborhood of the edge of the original strip, and it comprises one-third of the width and twice the length of the original strip.

Description: Cutting creates a second independent edge, half of which was on each side of the scissors. From Lawson's minimal Klein bottle we derive an embedding of the band into the 3-sphere S 3 , regarded as a subset of C 2 , which is geometrically the same as R 4. Geometry and the Imagination 2nd ed. A closely related 'strange' geometrical object is the Klein bottle. C 1 , however, then the theorem of Nash-Kuiper shows that no lower bound exists. Giving it extra twists and reconnecting the ends produces figures called paradromic rings. Constant positive curvature. A Treatise on the Afghan Bands. Using normal paper, this construction can be folded flat , with all the layers of the paper in a single plane, but mathematically, whether this is possible without stretching the surface of the rectangle is not clear. A system of differential-algebraic equations that describes models of this type was published in together with its numerical solution. Angewandte Chemie International Edition.
