  NationMaster - Encyclopedia: Topologist's sine curve
In the branch of mathematics known as topology, the topologist's sine curve is an example that has several interesting properties.
It is closed, but has similar properties to the topologist's sine curve -- it too is connected but not locally connected or path-connected.
This is a crude plot of the Topologist's sine curve.

  Topologist's sine curve - Wikipedia, the free encyclopedia
In the branch of mathematics known as topology, the topologist's sine curve is a topological space with several interesting properties that make it an important textbook example.
The topologist's sine curve can be defined as the graph of the function sin(1/x) over the interval (0, 1] extended by the single point (0,0).
The topologist's sine curve T is connected but neither locally connected nor path connected.

 Mathematician's insight helps unravel knotty problem
In knot theory, topologists are concerned with the spatial arrangements of unbroken lines that are folded in knots — not unlike a tangled kite string or fishing line.
It is known that enzymes dubbed topoisomerases have the job of unknotting those clumps, and topologists have been collaborating with cancer researchers in recent years to attempt to find novel cancer treatments that capitalize on that.
Topologists are keen to find ways to prove that two shapes, which may look very different, are truly inequivalent.

 Topology - Wikipedia, the free encyclopedia
It has often been said that a topologist is a person who cannot tell a donut from a coffee cup with a handle (because both are solids with a single hole).
Topology has sometimes been called rubber-sheet geometry, because it does not distinguish between a circle and a square (a circle made out of a rubber band can be stretched into a square) but does distinguish between a circle and a figure eight (you cannot stretch a figure eight into a circle without tearing).
The traditional joke is that the topologist can't tell the coffee cup she is drinking out of from the donut she is eating, since a sufficiently pliable donut could be reshaped to the form of a coffee cup by creating a dimple and progressively enlarging it, while shrinking the hole into a handle.

A topologist is a man who doesn't know the difference between a coffee cup and a doughnut.
Quite often it is not important, for all practical topologist's purposes, whether you have a cup or a doughnut.
For example, if you study holes (a very respectable topic in topology), you put a cup and a doughnut (or torus, as such objects are called in topology) into the same class of Objects with One Hole.

Topologists are concerned with those properties of objects and spaces that transcend mere geometry.
To the topologist, a sphere, for instance, can be stretched, compressed, or warped in any number of ways and still remain a sphere, so long as it isn't ripped or torn.
Both are examples of what they call a torus: a topologist can deform the former into the latter simply by shrinking the depression in the cup and the size of the cup itself, while enlarging the handle.

A topologist allows you to bend, stretch, or shrink a figure as long as you do not tear it or poke holes in it..
When you change things under these rules, you can form any new figure you want and the topologist would say that the new one and the original one are the same.
To the topologist, Q and P are the same thing.

It is this essential difference which distinguishes them as knots, and a topologist would certainly perceive that a pretzel was different from a ring- doughnut.
To a topologist who practises magic there is a very significant difference, not only between a Unicursal Hexagram and a 'Star of David' Hexagram, but also between a six-pointed star drawn by superimposing two triangles and one formed by interlocking the triangles.
A topologist would be much more concerned about these differences than by the orientation of the finished figure.

The Alexander polynomial was remarkable for how successful it was in distinguishing the knots in Tait's orginal table and it gave witness to how thorough a researcher Tait was.
If a lawyer can do research in knot theory, it can't be that hard.) Unforunately, there are many knots with equivalent Alexander polynomial that can be shown to be isotopically different through the uses of other invariants.
In particular, to a topologist there is no difference between the loops representing 4_1 and 5_1.
