Lens, Switzerland
Lens is a municipality in the district of Sierre in the canton of Valais in Switzerland.
History
Lens is first mentioned in 1177 as de Lenz.
Geography
Lens has an area, as of 2009, of 13.9 square kilometers (5.4 sq mi). Of this area, 5.07 km2 (1.96 sq mi) or 36.4% is used for agricultural purposes, while 5.48 km2 (2.12 sq mi) or 39.4% is forested. Of the rest of the land, 2.74 km2 (1.06 sq mi) or 19.7% is settled (buildings or roads), 0.1 km2 (25 acres) or 0.7% is either rivers or lakes and 0.46 km2 (0.18 sq mi) or 3.3% is unproductive land.
Of the built up area, housing and buildings made up 11.2% and transportation infrastructure made up 4.0%. while parks, green belts and sports fields made up 3.8%. Out of the forested land, 33.6% of the total land area is heavily forested and 5.8% is covered with orchards or small clusters of trees. Of the agricultural land, 0.4% is used for growing crops and 11.6% is pastures, while 9.1% is used for orchards or vine crops and 15.3% is used for alpine pastures. All the water in the municipality is in lakes.
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.
Drop (unit)
The drop is a unit of measure of volume, the amount dispensed as one drop from a dropper or drip chamber. It is often used in giving quantities of liquid drugs to patients, and occasionally in cooking.
The volume of a drop is not well-defined: it depends on the device and technique used to produce the drop, on the strength of the gravitational field, and on the density and the surface tension of the liquid.
There are several exact definitions of a "drop":
Drop (music)
A drop in popular music, especially electronic music styles, is a point in a music track where a switch of rhythm or bass line occurs and usually follows a recognizable build section and break.
The term "drop" comes from the composer or producer "dropping in" the primary rhythmic and foundational elements previously hinted at into the mix more or less at once. Related terms, typically describing certain types of drops, include "beat-up" (so named because it is a point where the producer brings up the foundational kick drum beat after having faded it down during a break or buildup) and "climax" (typically describing a single particularly striking drop heard late in the track).
Types
Many genres of EDM can have more than one drop during a track, especially if the song is built on a "dance-pop" verse/chorus with vocals; a drop of some kind is typically heard somewhere during each chorus as the high point of that verse/chorus cycle. Most genres, however, tend to emphasize a single drop as the beginning of the high point, or climax, of the entire track; in vocal subgenres this is typically the last repetition of the chorus, while in nonvocal genres it typically occurs in the last quarter of the track.
Overhand (boxing)
An overhand (or overcut or drop) is a semi-circular and vertical punch thrown with the rear hand. It is usually employed when the opponent is bobbing or slipping. The strategic utility of the drop relying on body weight can deliver a great deal of power.

Movies
Night (Bruce Springsteen song)
"Night" is a song by Bruce Springsteen which first appeared on the Born to Run album in 1975. Although this is one of the lesser known songs from Born to Run, "Night" has become somewhat of a stage favorite for the E Street Band. The song was not immediately played during the 1975 Born to Run Tour until later that year and more so in 1976 when it was used as the opening song. It was still sometimes being used as an opening song decades later during the 2007–2008 Magic Tour.
