Shadowgraph
Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation. In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras. However, all these disturbances refract light rays, so they can cast shadows. The plume of hot air rising from a fire, for example, can be seen by way of its shadow cast upon a nearby surface by the uniform sunlight. Sunlight shadowgraph Some aquatic predators detect their transparent prey by way of their shadows cast upon the ocean floor. It was Robert Hooke who first scientifically demonstrated the sunlight shadowgraph and Jean-Paul Marat who first used it to study fire. A modern account of shadowgraphy is given by Gary S. Settles.

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. Some ...

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. The oldest ...

Kai-Uwe Von Hassel
Kai-Uwe von Hassel (21 April 1913 – 8 May 1997) was a German politician from Schleswig-Holstein associated with the Christian Democratic Union (CDU). He served as Minister President of Schleswig-Holstein from 1954 to 1963, as Federal Minister of Defence from 1963 to 1966, and as Federal Minister for Displaced Persons, Refugees and War Victims from 1966 to 1969. From 1969 to 1972 he was the 4th President of the Bundestag. Life and career Hassel was born in Gare, German East Africa (now in Lushoto, Tanga Region, Tanzania), where his father Theodor von Hassel (1868–1935) had served as a ''Schutztruppe'' officer. After the First World War, the Hassel family was banished from Tanganyika by the British mandate administration and settled in Glücksburg, Schleswig-Holstein. Hassel took his ''Abitur'' school-leaving exam in 1933, trained as an agribusiness merchant, and returned to the Tanganyika Territory in 1935. At the beginning of the Second World War he was interned in Dar es Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myocardial Infarction
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often it occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat or feeling tired. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest. Most MIs occur due to coronary artery disease. Risk factors include high blood pressure, smoking, diabetes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Efringen-Kirchen
Efringen-Kirchen is a municipality in the district of Lörrach in Baden-Württemberg, Germany. Fortifications During World War I fortifications were built at Istein, these were destroyed at the end of the war. In 1936 plans were drawn up to turn the location into the "Gibraltar of the West" with two kilometres of underground passages linking gun emplacements and bunkers. The site was to host an underground garage for over 100 tanks, 3600 men and as part of the West Wall it would dwarf similar Maginot Line fortifications. Work began in 1937 and Hermann Göring visited in the Spring of 1938. By 1939 several installations were complete but as the war progressed advantageously for the Germans in 1940 the site remained unfinished.

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.
