Peter Salcher
Peter Salcher (Kreuzen, 10 August 1848 — Sušak, today part of Rijeka, 4 October 1928) was an Austrian and Croatian physicist. Biography He studied physics at the University of Graz, where he received his doctorate in 1872. After doctorate, he worked at the grammar school in Klagenfurt, then in Trieste, and in 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 has also run 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 singers, inspiration for the movie The Sound of Music.

Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction 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 properties ...

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 but 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 limited ph ...

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Röntgen
Wilhelm Conrad Röntgen (; ; 27 March 184510 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901.Novelize, Robert. ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. 1997. p. 1. In honour of Röntgen's accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him. The unit of measurement roentgen was also named after him. Biographical history Education He was born to Friedrich Conrad Röntgen, a German merchant and cloth manufacturer, and Charlotte Constanze Frowein. At age three his family moved to the Netherlands where his family lived. Röntgen attended high school at Utrecht Technical School in Utrecht, Netherland ...

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Whitehead Torpedo
The Whitehead torpedo was the first self-propelled or "locomotive" torpedo ever developed. It was perfected in 1866 by Robert Whitehead from a rough design conceived by Giovanni Luppis of the Austro-Hungarian Navy in Fiume. It was driven by a three-cylinder compressed-air engine invented, designed, and made by Peter Brotherhood. Many naval services procured the Whitehead torpedo during the 1870s, including the US Navy. This early torpedo proved itself in combat during the Russo-Turkish War when, on January 16, 1878, the Ottoman ship ''Intibah'' was sunk by Russian torpedo boats carrying Whiteheads, though this story has been disputed in one book. The term "torpedo" comes from the Torpedo fish, which is a type of ray that delivers an electric shock to stun its prey. History During the 19th century, an officer of the Austrian Marine Artillery conceived the idea of using a small boat laden with explosives, propelled by a steam or an air engine and steered by cables to be used a ...
