Schlieren (/ ˈ ʃ l ɪər ən / SHLEER-ən; German: [ˈʃliːʁn̩] ⓘ, German for 'streaks') are optical inhomogeneities in transparent media that are not necessarily visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of such inhomogeneities.
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.

Schlieren photography is a process for photographing fluid flow. Invented by the German physicist August Toepler in 1864 to study supersonic motion, ...
Just one year later, the company moved its base back to Schlieren, and in 1901, there was another renaming, to Schweizerische Wagons-Fabrik AG in Schlieren-Zürich (SWS). In 1903, the newly formed Swiss Federal Railways (SBB-CFF-FFS) ordered passenger cars from SWS. As early as 1906, the 1,000th item of rolling stock left the SWS workshop, and ...
The continent represents Tesla’s biggest headache worldwide after volumes dropped 11% last year to 327,000 vehicles, mainly owing to the loss of state subsidies in key markets like Germany.

August and Maximilian Toepler started research in the field of gas discharge physics at the Dresden University of Technology. This research particularly resulted in the development of the Schlieren technique. With the application of the “streak method” Toepler succeeded as the first scientist in making acoustic waves in the air visible.
