Post (comics)

Post is a fictional character and mutant in the Marvel Comics universe. His first appearance was in X-Men v2, #50.

Fictional character biography

Kevin Tremain was a mutant captured and studied by the Mandarin. On a secret mission, the Six Pack attacked the secret base Tremain was held in. Tremain was mortally injured; Cable tried to save his life, first by using his telekinesis to keep Tremain's body together, and finally by giving him a blood transfusion. Although it seems he survived this trauma, Cable seemed to think Tremain had later died.

Years later, Tremain resurfaced as Post, the lowest of Onslaught's emissaries. Onslaught forced Gateway to teleport Cyclops, Storm, Iceman, and Wolverine to where Post could "test" them. The four managed to defeat Post and were transported back to the Mansion. Later, Post attacked Cable, who instantly recognized his identity as Tremain. Post defeated Cable and left him for the Hulk to finish off. Post was later charged with ensuring the Sentinels would launch, he battled X-Factor with them and succeeded protecting the Sentinels. He and his master Onslaught were eventually defeated by the heroes.

Top

A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.

Characteristics

The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.

Category of topological spaces

In mathematics, the category of topological spaces, often denoted Top, is the category whose objects are topological spaces and whose morphisms are continuous maps or some other variant; for example, objects are often assumed to be compactly generated. This is a category because the composition of two continuous maps is again continuous. The study of Top and of properties of topological spaces using the techniques of category theory is known as categorical topology.

N.B. Some authors use the name Top for the category with topological manifolds as objects and continuous maps as morphisms.

As a concrete category

Like many categories, the category Top is a concrete category (also known as a construct), meaning its objects are sets with additional structure (i.e. topologies) and its morphisms are functions preserving this structure. There is a natural forgetful functor

to the category of sets which assigns to each topological space the underlying set and to each continuous map the underlying function.

Top (tool)

A top (also called a rope wrench, rope separator or rope tool) is a tool used in the manufacture of laid rope.

The top is used to prevent the strands of a rope twisting together prematurely, which would lead to the rope being loose, allowing it to untwist. The amount of pressure applied to the top determines the stiffness of the final product; more pressure forces the strands together more tightly, making a rope that is harder to bend.

Tops come in a variety of forms for use on different types of rope. The simplest is a forked stick, used to create three strand rope, however more elaborate grooved bullet-shaped and cast iron types are available.

Depending on the gauge of rope being made, the top can either be handheld or mounted on a trolley that moves along the ropewalk.
