Peter Salcher
Peter Salcher (Kreuzen, 10 August 1848 — Sušak, Rijeka, Sušak, today part of Rijeka, 4 October 1928) was an Austrians, Austrian and Croats, Croatian physicist. Biography He studied physics at the University of Graz, where he received his Doctoral degree, doctorate in 1872. After their doctorate, he worked at the grammar school in Klagenfurt, then in Trieste, and 1875 he came to the Imperial and Royal Naval Academy in Rijeka for professors of physics and mechanics and leader physics laboratory; From 1880 he also ran a meteorological station. Rijeka Academy then was one of the top higher education and research institutions of Austria-Hungary, with carefully selected staff and excellently equipped. During his tenure at the Academy, one of Salcher's students was Georg von Trapp, one of the most highly decorated officers of the Austro-Hungarian Navy in World War I and patriarch of the Trapp Family, Trapp Family singers, inspiration for the movie The Sound of Music (film), The Sound ...

Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during chemical reaction, reactions with other chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the prop ...

Physicists From Austria-Hungary
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applied phy ...

High-speed Photography
High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive frames. High-speed photography can be considered to be the opposite of time-lapse photography. In common usage, high-speed photography may refer to either or both of the following meanings. The first is that the photograph itself may be taken in a way as to appear to freeze the motion, especially to reduce motion blur. The second is that a series of photographs may be taken at a high sampling frequency or frame rate. The first requires a sensor with good sensitivity and either a very good shuttering system or a very fast strobe light. The second requires some means of capturing successive frames, either with a mechanical device or by moving data off electronic sensors very qu ...

Photojournalist
Photojournalism is journalism that uses images to tell a news story. It usually only refers to still images, but can also refer to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography (such as documentary photography, social documentary photography, war photography, street photography and celebrity photography) by having a rigid ethical framework which demands an honest and impartial approach that tells a story in strictly journalistic terms. Photojournalists contribute to the news media, and help communities connect with one other. They must be well-informed and knowledgeable, and are able to deliver news in a creative manner that is both informative and entertaining. Similar to a writer, a photojournalist is a reporter, but they must often make decisions instantly and carry photographic equipment, often while exposed to significant obstacles, among them immediate physical danger, bad weather, large crowds, and limi ...

X-ray
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 Nanometre, nanometers to 10 Picometre, picometers, corresponding to frequency, frequencies in the range of 30 Hertz, petahertz to 30 Hertz, exahertz ( to ) and photon energies in the range of 100 electronvolt, eV to 100 keV, respectively. X-rays were discovered in 1895 in science, 1895 by the German scientist Wilhelm Röntgen, Wilhelm Conrad Röntgen, who named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medical diagnostics (e.g., checking for Bo ...

Wilhelm Röntgen
Wilhelm Conrad Röntgen (; 27 March 1845 – 10 February 1923), sometimes Transliteration, transliterated as Roentgen ( ), was a German physicist who produced and detected electromagnetic radiation in a wavelength range known as X-rays. As a result of this discovery, he became the first recipient of the Nobel Prize in Physics in 1901.Novelize, Robert. ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th ed. 1997. p. 1. Biographical history Education Röntgen was born in Lennep on 27 March 1845 to Friedrich Conrad Röntgen, a German merchant and cloth manufacturer, and Charlotte Constanze Frowein. When he was aged three, his family moved to the Netherlands, where his mother's family lived, rendering him Statelessness, stateless. He attended high school at Utrecht Technical School in Utrecht, Netherlands. He followed courses at the Technical School for almost two years. In 1865, he was unfairly expelled from high school when one of his teachers intercepted a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnel
A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunnel configuration includes air ducting to and from the test section and a device for keeping the air in motion, such as a fan. Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on Building, buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over , and with air speeds from a light breeze to hypersonic. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautical research, as part of the effort to develop heavier-than-air flying machines. The wind tunnel reversed the usual situation. Instead of the air standing still and an aircraft moving, an object would be held still and the air moved around it. ...

Whitehead Torpedo Works
Whitehead Torpedo Works was a company established in the 19th century by Robert Whitehead (engineer), Robert Whitehead that developed the Whitehead torpedo. It grew from its initial location at Fiume to Wyke Regis and to Livorno, but the former two plants closed by the end of World War II. The Italian branch maintained the name Whitehead for a long time into the late 20th century, and still exists as Leonardo Sistemi di Difesa . History Robert Whitehead (engineer), Robert Whitehead worked for a metal foundry in the city of Fiume (today Rijeka, Croatia), and became its manager in 1856, and changed its name to ''Stabilimento Tecnico di Fiume'' (STF). STF produced marine steam boilers and engines, including for the Austro-Hungarian Navy. The invention of the self-propelled torpedo happened at that company, but it was not profitable and the company went bankrupt in 1873. The Whitehead company, Torpedo-Fabrik von Robert Whitehead, was founded in 1875 and would produce for the first tor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
