Lens (geology)
In geology a lens is a body of ore or rock or a deposit that is thick in the middle and thin at the edges, resembling a convex lens in cross-section. Adjective: "lenticular".
A lens can also refer to an irregular shaped formation consisting of a porous, permeable sedimentary deposit surrounded by impermeable rock.
Lens (anatomy)
The crystalline lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. The lens, by changing shape, functions to change the focal distance of the eye so that it can focus on objects at various distances, thus allowing a sharp real image of the object of interest to be formed on the retina. This adjustment of the lens is known as accommodation (see also below). Accommodation is similar to the focusing of a photographic camera via movement of its lenses. The lens is more flat on its anterior side than on its posterior side.
The lens is also known as the aquula (Latin, a little stream, dim. of aqua, water) or crystalline lens. In humans, the refractive power of the lens in its natural environment is approximately 18 dioptres, roughly one-third of the eye's total power.
Structure
The lens is part of the anterior segment of the eye. Anterior to the lens is the iris, which regulates the amount of light entering into the eye. The lens is suspended in place by the suspensory ligament of the lens, a ring of fibrous tissue that attaches to the lens at its equator and connects it to the ciliary body. Posterior to the lens is the vitreous body, which, along with the aqueous humor on the anterior surface, bathes the lens. The lens has an ellipsoid, biconvex shape. The anterior surface is less curved than the posterior. In the adult, the lens is typically circa 10 mm in diameter and has an axial length of about 4 mm, though it is important to note that the size and shape can change due to accommodation and because the lens continues to grow throughout a person's lifetime.

Soul music
Soul music is a popular music genre that originated in the United States in the late 1950s and early 1960s. It combines elements of African-American gospel music, rhythm and blues and jazz. Soul music became popular for dancing and listening in the United States; where record labels such as Motown, Atlantic and Stax were influential in the civil rights era. Soul also became popular around the world, directly influencing rock music and the music of Africa.
According to the Rock and Roll Hall of Fame, soul is "music that arose out of the black experience in America through the transmutation of gospel and rhythm & blues into a form of funky, secular testifying". Catchy rhythms, stressed by handclaps and extemporaneous body moves, are an important feature of soul music. Other characteristics are a call and response between the soloist and the chorus, and an especially tense vocal sound. The style also occasionally uses improvisational additions, twirls and auxiliary sounds. Soul music reflected the African-American identity, it stressed the importance of an African-American culture. The new-found African-American consciousness led to new music, which boasted pride in being black.
Dimension (data warehouse)
A dimension is a structure that categorizes facts and measures in order to enable users to answer business questions. Commonly used dimensions are people, products, place and time.
In a data warehouse, dimensions provide structured labeling information to otherwise unordered numeric measures. The dimension is a data set composed of individual, non-overlapping data elements. The primary functions of dimensions are threefold: to provide filtering, grouping and labelling.
These functions are often described as "slice and dice". Slicing refers to filtering data. Dicing refers to grouping data. A common data warehouse example involves sales as the measure, with customer and product as dimensions. In each sale a customer buys a product. The data can be sliced by removing all customers except for a group under study, and then diced by grouping by product.
A dimensional data element is similar to a categorical variable in statistics.
Typically dimensions in a data warehouse are organized internally into one or more hierarchies. "Date" is a common dimension, with several possible hierarchies:
