Poetry can follow a strict structure, or none at all, but many different types of poems use poetic devices. Poetic devices are tools that a poet can use to create rhythm, enhance a poem's meaning, or intensify a mood or feeling. These devices help piece the poem together, much like a hammer and nails join planks of wood together.
Hyperspace (science fiction) Hyperspace is a method of traveling sometimes used in science fiction. It is typically described as an alternative region of space co-existing with our own universe which may be entered using an energy field or other device. Travel in hyperspace is typically depicted as faster-than-light travel in normal space.
In mathematics, a hyperbola (plural hyperbolas or hyperbolae) is a type of smooth curve, lying in a plane, defined by its geometric properties or by equations for which it is the solution set. hyperbola may be defined equivalently as the locus of points where the absolute value of the difference of the distances to the two foci is a constant equal to 2 a, the distance between its two vertices.
