    The number of tines on tools varies widely – a pitchfork may have just two, a garden fork may have four, and a rake or harrow many. Tines may be blunt, such as those on a fork used as an eating utensil; or sharp, as on a pitchfork; or even barbed, as on a trident. The terms tine and prong are synonymous. A tooth of a comb is a tine.

  3. Atlas (topology) - Wikipedia

    en.wikipedia.org/wiki/Atlas_(topology)

    A transition map provides a way of comparing two charts of an atlas. To make this comparison, we consider the composition of one chart with the inverse of the other. This composition is not well-defined unless we restrict both charts to the intersection of their domains of definition. (For example, if we have a chart of Europe and a chart of ...

    Although the wind speeds and photographic damage examples are updated, which are more or less still accurate. [citation needed] However, for the actual TORRO scale in practice, damage indicators (the type of structure which has been damaged) are predominantly used in determining the tornado intensity.

    For example, when a rectangle is rotated around an axis parallel to one of its edges, then a hollow rectangle-section ring is produced. If the revolved figure is a circle, then the object is called a torus. The term toroid is also used to describe a toroidal polyhedron. In this context a toroid need not be circular and may have any number of holes.

    Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
