Zoetrope (other)
A zoetrope is a Precursors of film#Modern era, pre-film animation device that produces the illusion of motion, by displaying a sequence of drawings or photographs showing progressive phases of that motion. A zoetrope is a cylindrical variant of the phenakistiscope, phénakisticope, an apparatus suggested after the stroboscopic discs were introduced in 1833. The definitive version of the zoetrope, with replaceable film picture film strips, was introduced as a toy by Milton Bradley Company, Milton Bradley in 1866 and became very successful. Etymology The name ''zoetrope'' was composed from the Greek root words ζωή ''zoe'', "life" and τρόπος ''tropos'', "turning" as a translation of "wheel of life". The term ''soetrope'' was coined by inventor William E. Lincoln. Technology The zoetrope consists of a cylinder with cuts vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures. As the cylinder spins, the user looks ...

Zoetrope
A zoetrope is one of several pre-film animation devices that produce the illusion of motion by displaying a sequence of drawings or photographs showing progressive phases of that motion. It was basically a cylindrical variation of the phénakisticope, suggested almost immediately after the stroboscopic discs were introduced in 1833. The definitive version, with easily replaceable picture strips, was introduced as a toy by Milton Bradley in 1866 and became very successful. Etymology The name ''zoetrope'' was composed from the Greek root words ζωή ''zoe'', "life" and τρόπος ''tropos'', "turning" as a translation of "wheel of life". The term was coined by inventor William E. Lincoln. Technology The zoetrope consists of a cylinder with cuts vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures. As the cylinder spins, the user looks through the cuts at the pictures across. The scanning of the slits keeps the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Nepomuk Czermak
Johann Nepomuk Czermak (17 June 1828 – 16 September 1873) was an Austrian-German physiologist who was a native of Prague. He studied in Prague, Vienna, Breslau and Würzburg. At Breslau he was greatly influenced by the work of physiologist Jan Evangelista Purkyně (1787–1869). He became a professor at Graz in 1855, and proceeded to work at several European universities, including Krakow (1856/57) and Leipzig (from 1869). Just prior to his death in 1873, he founded a physiological institute in Leipzig called the "Spectatorium". Czermak was a member of the Austrian Academy of Sciences. Contributions Czermak is remembered for his contributions made in the field of laryngology. Along with neurologist Ludwig Turck (1810–1868), he is credited for introducing the laryngoscope into medicine. The laryngoscope was created by Spanish singing instructor Manuel Garcia (1805–1906) in 1854 — shortly afterwards, Czermak made modifications to the device, and it soon gained pop ...

Myrtle Avenue (BMT Fourth Avenue Line)
The Myrtle Avenue station was a local station on the Manhattan Bridge subway tracks () in Brooklyn, New York City, at the southern end of the bridge. History This station opened on June 22, 1915, along with the rest of the BMT Fourth Avenue Line. The Myrtle Avenue station was sometimes called Gold Street in some early planning documents, and in the ''Brooklyn Daily Eagle'' when the station opened. The city government took over the BMT's operations on June 1, 1940. The station closed on July 16, 1956 for the reconstruction of the flying junction north of DeKalb Avenue to increase capacity for the entire BMT Division. The Brooklyn-bound platform was removed completely, but the Manhattan-bound platform still exists. This station was a casualty of the rebuild. A new track had to be added on the west side to allow for a grade-separated crossing. The original southbound "local" track at the platform had to be depressed to a lower grade to cross under, and the new track wiped out th ...

Helmholtz
Hermann Ludwig Ferdinand von Helmholtz (31 August 1821 – 8 September 1894) was a German physicist and physician who made significant contributions in several scientific fields, particularly hydrodynamic stability. The Helmholtz Association, the largest German association of research institutions, is named in his honor. In the fields of physiology and psychology, Helmholtz is known for his mathematics concerning the eye, theories of vision, ideas on the visual perception of space, color vision research, the sensation of tone, perceptions of sound, and empiricism in the physiology of perception. In physics, he is known for his theories on the conservation of energy, work in electrodynamics, chemical thermodynamics, and on a mechanical foundation of thermodynamics. As a philosopher, he is known for his philosophy of science, ideas on the relation between the laws of perception and the laws of nature, the science of aesthetics, and ideas on the civilizing power of science. ...

James Clerk Maxwell
James Clerk Maxwell (13 June 1831 – 5 November 1879) was a Scottish mathematician and scientist responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the " second great unification in physics" where the first one had been realised by Isaac Newton. With the publication of "A Dynamical Theory of the Electromagnetic Field" in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. He proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. (This article accompanied an 8 December 1864 presentation by Maxwell to the Royal Society. His statement that "light and magnetism are affections of the same substance" is at page 499.) The unification of light and electrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Cruikshank
George Cruikshank (27 September 1792 – 1 February 1878) was a British caricaturist and book illustrator, praised as the "modern Hogarth" during his life. His book illustrations for his friend Charles Dickens, and many other authors, reached an international audience. Early life Cruikshank was born in London. His father, Edinburgh-born Isaac Cruikshank, was one of the leading caricaturists of the late 1790s and Cruikshank started his career as his father's apprentice and assistant. His older brother, Isaac Robert, also followed in the family business as a caricaturist and illustrator. Cruikshank's early work was caricature; but in 1823, at the age of 31, he started to focus on book illustration. He illustrated the first, 1823 English translation (by Edgar Taylor and David Jardine) of ''Grimms' Fairy Tales'', published in two volumes as ''German Popular Stories''. On 16 October 1827, he married Mary Ann Walker (1807–1849). Two years after her death, on 7 March 1851, he m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grecian Bend
The Grecian bend was a term applied first to a stooped posture which became fashionable c. 1820, named after the gracefully-inclined figures seen in the art of ancient Greece. It was also the name of a dance move introduced to polite society in America just before the American Civil War. The "bend" was considered very daring at the time. The stoop or the silhouette created by the fashion in women's dress for corsets, crinolettes and bustles by 1869 was also called the Grecian bend. Contemporary illustrations often show a woman with a large bustle and a very small parasol, bending forward. The term was also given to those who suffered from decompression sickness, or "the bends", due to working in caissons during the building of the Brooklyn Bridge in New York City. The name was given because afflicted individuals characteristically arched their backs in the same manner as the then popular "Grecian bend" fashion.Kumar V., Abbas A., Fausto N.

Cubic Crystal System
In crystallography, the cubic (or isometric) crystal system is a crystal system where the Crystal_structure#Unit_cell, unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals. There are three main varieties of these crystals: *Primitive cubic (abbreviated ''cP'' and alternatively called simple cubic) *Body-centered cubic (abbreviated ''cI'' or bcc) *Face-centered cubic (abbreviated ''cF'' or fcc, and alternatively called Close-packing_of_equal_spheres, ''cubic close-packed'' or ccp) Each is subdivided into other variants listed below. Although the ''unit cells'' in these crystals are conventionally taken to be cubes, the primitive_cell, primitive unit cells often are not. Bravais lattices The three Bravais lattices in the cubic crystal system are: The primitive cubic lattice (cP) consists of one Lattice_(group), lattice point on each corner of the cube; this means each simple cubic unit cell has in total one latt ...

Robert Hallowell Richards
Robert Hallowell Richards (August 26, 1844 – March 27, 1945) was an American mining engineer, metallurgist, and educator, born at Gardiner, Maine. In 1868, with the first class to leave the institution, he graduated from the Massachusetts Institute of Technology, and there he taught for 46 years, becoming professor of mineralogy and assaying in 1871, head of the department of mining engineering in 1873, and in 1884 professor also of metallurgy. The laboratories which he established at the Institute were the first of their kind in the world. He retired in 1914. Richards invented a jet aspirator for chemical and physical laboratories and a prism for stadia surveying. But it was in the field of ore dressing that he became especially distinguished. He determined the curves of material settling in water, thereby establishing the fundamental principles of sorting ore by means of jigs and other machines. He invented separators for Lake Superior copper, Virginia iron, and three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indianapolis Daily Journal
The ''Indianapolis Journal'' was a newspaper published in Indianapolis, Indiana, during the nineteenth and early twentieth centuries. The paper published daily editions every evening except on Sundays, when it published a morning edition. The first issue of the then-named ''Indiana Journal'' was published on January 11, 1825, by partners John Douglass and Douglass Maguire. From the outset the paper advocated for government sponsored internal improvements and protective tariffs that would aid Indiana’s agricultural economy. These positions led the ''Journal'' to align with the Whig Party beginning in the mid-1830s. Purchased in 1845 by John D. Defrees, and operated by him for nearly a decade, the paper was the first in Indianapolis to install a steam driven printing press. Under his leadership, the paper became Indianapolis's first permanent daily, the ''Daily Indiana State Journal'' in April 1851. The title changed to ''Indianapolis Morning Journal'' in 1853, then to ''Indianapo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
