A helicoid with α = 1, −1 ≤ ρ ≤ 1 and − π ≤ θ ≤ π. The helicoid , also known as helical surface , is a smooth surface embedded in three-dimensional space . It is the surface traced by an infinite line that is simultaneously being rotated and lifted along its fixed axis of rotation.
Perhaps the ultimate document structuring challenge is to generate a good narrative—in other words, a text which starts by setting the scene and giving an introduction/overview; then describes a set of events in a clear fashion, so readers can easily see how the individual events are related and link together; and concludes with a summary/ending.
generalized helicoid: meridian is a parabola. In geometry, a generalized helicoid is a surface in Euclidean space generated by rotating and simultaneously displacing a curve, the profile curve, along a line, its axis. Any point of the given curve is the starting point of a circular helix.
In typesetting, widows and orphans are single lines of text from a paragraph that dangle at either the beginning or end of a block of text, or form a very short final line at the end of a paragraph. [1] When split across pages, they occur at either the head or foot of a page (or column), unaccompanied by additional lines from the same paragraph ...
The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix.. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis.
A structure editor, also structured editor or projectional editor, is any document editor that is cognizant of the document's underlying structure.Structure editors can be used to edit hierarchical or marked up text, computer programs, diagrams, chemical formulas, and any other type of content with clear and well-defined structure.

In fluid dynamics, an isotropic helicoid is a shape that is helical, so it rotates as it moves through a fluid, and yet is isotropic, so that its rotation and drag are the same for all orientations of the particle.
