Rolling without slipping on Mobius strip

Consider the classical equation of a Mobius strip in parametric form. By using animation shows how movement can occur on the non-oriented surface. We will choose the route as the closed curve belonging to the surface. The sphere was selected as moving geometric object that visually continuously rolls over the surface of a Mobius strip.<img src="/view.aspx?si=154226/mobius_strip_rolling.PNG" alt="Rolling without slipping on Mobius strip" align="left"/>Consider the classical equation of a Mobius strip in parametric form.

Static fractal viewer for the Julia sets of the exponential map lambda*exp(z), with variable lambda. Allows adjustable viewing window, zoom-in and display of periodic attractors up to period 5. Dynamic version can generate animated views, like the Knaster explosion of period 3 shown on the figure.<img src="/view.aspx?si=153953/3djulia.png" alt="Exponential map fractal viewer" align="left"/>Static fractal viewer for the Julia sets of the exponential map lambda*exp(z), with variable lambda.

<p><strong>Introduction</strong></p>
<p>The special points of a set in a topological space are limit points, closure points, interior points, boundary points, exterior points, and isolated points. Except limit points and isolated points the other special points can be computed by implementing simple formulas. For limit points we have to resort to the very definition to find them. On the other hand all special points can be derived from limit points. We have found computer procedures to compute the limit points of a set in finite space. Upon these procedures we have created other procedures to find the other special points. The software used is Maple 15. Some ready-made procedures are also used.</p>
<p>Let X be a finite topological space and A is a sub set of X. If the limit points, closure, interior, boundary, exterior and isolated points of A are denoted by LimitPoints(A), ClosurePoints(A), BoundaryPoints(A), InteriorPoints(A), ExteriorPoints(A) and IsolatedPoints(A) respectively, then we have :</p>
<p>ClosurePoints(A) = A U LimitPoints(A) .</p>
<p>BoundaryPoints(A) = ClosurePoints(A) ∩ ClosurePoints(X−A) .</p>
<p>InteriorPoints(A) = ClosurePoints(A) − BoundaryPoints(A) .</p>
<p>ExteriorPoints(A) = InteriorPoints(X − A) .</p>
<p>IsolatedPoints(A) = A − LimitPoints(A) .</p>

By using complex numbers to represent points in the plane, and the concept of iterated function system, we efficiently describe fractal sets of any dimension from 0 to 2 and continuous curves that pass through them. Maple's animation feature allows us to make "movies" that show the transition through different dimensions.<img src="/view.aspx?si=4869/thumb.png" alt="Fractal Dimension and Space-Filling Curves (with iterated function systems)" align="left"/>By using complex numbers to represent points in the plane, and the concept of iterated function system, we efficiently describe fractal sets of any dimension from 0 to 2 and continuous curves that pass through them.

Welcome to the worksheet version of MOISE, a Maple library for doing calculations with simplicial complexes. MOISE started out as just the procedure "homology", which computes the homology of a simplicial complex. The algorithm used by "homology" follows the one given in James Munkres' book "Algebraic Topology". It is an old and straightforward method for computing homology groups, but one that is hard to do by hand. In addition to computing the homology groups of a complex, MOISE also contains a number of functions that operate on simplicial complexes.<img src="/view.aspx?si=3703//applications/images/app_image_blank_lg.jpg" alt="MOISE - A Topology Package for Maple" align="left"/>Welcome to the worksheet version of MOISE, a Maple library for doing calculations with simplicial complexes.

Knot theory is a mathematical study of knots. It is mainly used to distinguish between different types of knots and links. There are some practical applications of knots that are discussed in more detail later. Looking at the history of Knot theory, before people used to try to twist wires or threads and try to classify different types of knots. Nowadays, this can be done on the computer.
