The conventional schlieren system is credited mostly to German physicist August Toepler, though Jean Bernard Léon Foucault invented the method in 1859 that Toepler improved upon. Toepler's original system [ 2 ] was designed to detect schlieren in glass used to make lenses.
Schlieren was first mentioned in 828. [3] Until 1415, Schlieren belonged to Habsburg. After the conquest of Aargau by the Swiss Confederates it was a component of the county of Baden. In 1803 Schlieren was assigned to the Canton of Zürich. In 1777 the minister Heinrich Keller created here the first "deaf-mute school" in Switzerland.

Schwarzbier—a dark lager beer. Seltzer—carbonated water, a genericized trademark that derives from the German town Selters, which is renowned for its mineral springs.
The term "schlieren imaging" is commonly used as a synonym for schlieren photography, though this article particularly treats visualization of the pressure field produced by ultrasonic transducers, generally in water or tissue-mimicking media. The method provides a two-dimensional (2D) projection image of the acoustic beam in real-time ("live ...
The Schlern (Austrian German:; Italian: Sciliar; Ladin: Sciliër; 2,563 m) is a mountain of the Dolomites in South Tyrol, Italy. [1] The peak at the north west end of the mountain (left, in the image at right) was first ascended in July 1880 by Johann Santner.

This list of German abbreviations includes abbreviations, acronyms and initialisms found in the German language. Because German words can be famously long, use of abbreviation is particularly common. Even the language's shortest words are often abbreviated, such as the conjunction und (and) written just as "u." This article covers standard ...
Schlieren photography is a process for photographing fluid flow. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects.
