Tlingit (sh) and turbulence (sh)


Tlingit (sh)




Northernmost group of Northwest Coast Indian peoples who inhabit the islands and coast of southern Alaska, U.S. The Tlingit language is thought to be related to Athabaskan.

The basic social unit was the lineage, based on maternal lines of descent; clans and larger units (moieties) were also important. Each lineage had its own chief, owned and exploited lands of economic importance, and functioned as a ceremonial unit. The economy was based on salmon fishing, though sea and land mammals were also hunted. Wood, often decorated with stylized designs, was used for houses, totem poles, canoes, dishes, and Other objects. The potlatch marked a cycle of rituals mourning the death of a chief. The Tlingit number about 20,000.


turbulence (sh)




In fluid mechanics, a flow condition (see turbulent flow) in which local speed and pressure change unpredictably as an average flow is maintained.

Common examples are wind and water swirling around obstructions, or fast flow (Reynolds number greater than 2,100) of any sort. Eddies, vortices, and a reduction in drag are characteristics of turbulence. Lowered drag enables Golf balls to Travel farther than they would do otherwise, and the dimpled surface of Golf balls is meant to encourage turbulence in the boundary layer. If swimsuits with rough surfaces help swimmers to move faster, as has been claimed, the same explanation may apply.
