Schlieren Photography
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. Classical optical system The classical implementation of an optical schlieren system uses light from a single collimated source shining on, or from behind, a target object. Variations in refractive index caused by density gradients in the fluid distort the collimated light beam. This distortion creates a spatial variation in the intensity of the light, which can be visualised directly with a shadowgraph system. Classical schlieren imaging systems appear in two configurations, using either one or two mirrors. In each case, a transparent object is illuminated with collimated or nearly-collimated light. Rays that are not deflected by the object proceed to their focal point, where they are blocked by a knife edge. Rays that are deflected b ...

High Speed Camera
A high-speed camera is a device capable of capturing moving images with exposures of less than 1/1,000 second or frame rates in excess of 250 fps. It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used film to record the high-speed events, but were superseded by entirely electronic devices using either a charge-coupled device (CCD) or a CMOS active pixel sensor, recording, typically, over 1,000 fps onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena. Overview A high-speed camera can be classified as: # A high-speed film camera which records to film, # A high-speed video camera which records to electronic memory, # A high-speed framing camera which records images on multiple image planes or multiple locations on the same image plane (generally film or a network of CCD cameras), # A hig ...

Z4 (computer)
The Z4 was arguably the world's first commercial digital computer. It was designed, and manufactured by early computer scientist Konrad Zuse's company ''Zuse Apparatebau'', for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen, and not delivered by the defeat of Nazi Germany, in 1945. The Z4 was Zuse's final target for the Z3 design. Like the earlier Z2, it comprised a combination of mechanical memory and electromechanical logic, so was not a true electronic computer. Construction The Z4 was very similar to the Z3 in its design but was significantly enhanced in a number of respects. The memory consisted of 32-bit rather than 22-bit floating point words. The Program Construction Unit (''Planfertigungsteil'') punched the program tapes, making programming and correcting programs for the machine much easier by the use of symbolic operations and memory cells. Numbers were entered and output as decimal floating-poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weil Am Rhein
Weil am Rhein (High Alemannic: ''Wiil am Rhii'') is a German town and commune. It is on the east bank of the River Rhine, and extends to the point at which the Swiss, French and German borders meet. It is the most southwesterly town in Germany and a suburb of the Swiss city Basel. Weil am Rhein is part of the "trinationale Agglomeration Basel" with about 830,000 inhabitants. Geography Weil am Rhein is located at in the district of Lörrach in the Federal State of Baden-Württemberg. The city limits border France to the west and Switzerland to the south including the triple border of the three countries. Locally, Weil is situated in the region referred to as Markgräflerland. The city's location on the Rhine and proximity to the Black Forest give it a continental climate, particularly suited to viticulture. Karte Weil am Rhein.png, Map of Weil am Rhein History The town is first documented in the year 786 as ''Willa'', a name which is thought to be of Roman origin. The duc ...

Freiburg Im Breisgau
Freiburg im Breisgau (; abbreviated as Freiburg i. Br. or Freiburg i. B.; Low Alemannic: ''Friburg im Brisgau''), commonly referred to as Freiburg, is an independent city in Baden-Württemberg, Germany. With a population of about 230,000 (as of 31 December 2018), Freiburg is the fourth-largest city in Baden-Württemberg after Stuttgart, Mannheim, and Karlsruhe.

Photographers From Berlin
A photographer (the Greek φῶς (''phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light") is a person who makes photographs. Duties and types of photographers As in other arts, the definitions of amateur and professional are not entirely categorical. An '' amateur photographer'' takes snapshots for pleasure to remember events, places or friends with no intention of selling the images to others. A ''professional photographer'' is likely to take photographs for a session and image purchase fee, by salary or through the display, resale or use of those photographs. A professional photographer may be an employee, for example of a newspaper, or may contract to cover a particular planned event such as a wedding or graduation, or to illustrate an advertisement. Others, like fine art photographers, are freelancers, first making an image and then licensing or making printed copies of it for sale or display. ...

Film People From Freiburg Im Breisgau
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ballistics Experts
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance. A ballistic body is a free-moving body with momentum which can be subject to forces such as the forces exerted by pressurized gases from a gun barrel or a propelling nozzle, normal force by rifling, and gravity and air drag during flight. A ballistic missile is a missile that is guided only during the relatively brief initial phase of powered flight and the trajectory is subsequently governed by the laws of classical mechanics; in contrast to (for example) a cruise missile which is aerodynamically guided in powered flight like a fixed-wing aircraft. History and prehistory The earliest known ballistic projectiles were stones and spears, and the throwing stick. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
