Strictly speaking, del is not a specific operator, but rather a convenient mathematical notation for those three operators, that makes many equations easier to write and remember. The del symbol can be interpreted as a vector of partial derivative operators, and its three possible meanings—gradient, divergence, and curl—can be formally viewed as the product with a scalar, dot product, and cross product, respectively, of the del "operator" with the field. These formal products do not necessarily commute with other operators or products.
A deel (Mongolian:дээл[teːɮ]; Buryat: дэгэл) is an item of traditional clothing commonly worn since centuries ago among the Mongols and other nomadic tribes of Central Asia, including various Turkic peoples, and can be made from cotton, silk, wool, or brocade.
The deel is still commonly worn by both men and women outside major towns, especially by herders. In urban areas, deels are mostly only worn by elderly people, or on festive occasions. The deel appears similar to a caftan or an old European folded tunic. Deels typically reach to below the wearer's knees and fan out at the bottom and are commonly blue, olive, or burgundy, though there are deels in a variety of other colors.
The deel looks like a large overcoat when not worn. Instead of buttoning together in the middle, the sides are pulled against the wearers body, the right flap close to the body with the left covering. On the right side of the wearer are typically 5 or 6 clasps to hold the top flap in place. There is one clasp below the armpit, three at the shoulder, and either one or two at the neckline.
The song is about teenagers experiencing criticism and rejection and being held responsible for everything.
A Chinese language version of "Junge" was released on the compilation Poptastic Conversation China on August 1, 2008.
The video for the single is very graphic and depicts various violent attacks by zombies to town members, while the band Die Ärzte looks on helplessly from the top of a broadcast van and sings about teenagers ruining their lives.
The band use a variety of makeshift weapons, such as a guitar, binoculars and a beer can, before a crossbow is produced from out of nowhere in a section that resembles a scene from the 2004 British film Shaun of the Dead. The zombies are finally overwhelming and guitarist Farin Urlaub gets eaten at the end. It was directed by Norbert Heitker.
The opening scene, where a bleeding zombie child is walking down the street, is a parody of the opening scene of the film Arlington Road.
