Photomicrography
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon Small World
Nikon Small World (Nikon's Small World) is a photographic contest run by Nikon Instruments and a forum for showcasing the beauty and complexity of life as seen through the light microscope. It serves as a window into a world that can only be seen through the lens of an optical microscope. The contest comprises two separate competitions: * The annual Nikon Small World Photomicrography Competition is open to anyone with an interest in microscopy and photography from the widest array of scientific disciplines. The competition first began in 1975 as a means to recognize the efforts of those involved with photography through the light microscope. Any type of camera equipment and light microscopy technique is acceptable, including phase contrast, polarized light, fluorescence, interference contrast, dark-field, confocal, deconvolution, and mixed techniques. * The annual Nikon Small World In Motion Competition encompasses any movie or digital time-lapse photography taken through the ...

Microscopic Photography Strawberry
The microscopic scale () is the scale of objects and events smaller than those that can easily be seen by the naked eye, requiring a lens or microscope to see them clearly. In physics, the microscopic scale is sometimes regarded as the scale between the macroscopic scale and the quantum scale. Microscopic units and measurements are used to classify and describe very small objects. One common microscopic length scale unit is the micrometre (also called a ''micron'') (symbol: μm), which is one millionth of a metre. History Whilst compound microscopes were first developed in the 1590s, the significance of the microscopic scale was only truly established in the 1600s when Marcello Malphigi and Antonie van Leeuwenhoek microscopically observed frog lungs and microorganisms. As microbiology was established, the significance of making scientific observations at a microscopic level increased. Published in 1665, Robert Hooke’s book Micrographia details his microscopic observations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnification
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification". When this number is less than one, it refers to a reduction in size, sometimes called ''minification'' or ''de-magnification''. Typically, magnification is related to scaling up visuals or images to be able to see more detail, increasing resolution, using microscope, printing techniques, or digital processing. In all cases, the magnification of the image does not change the perspective of the image. Examples of magnification Some optical instruments provide visual aid by magnifying small or distant subjects. * A magnifying glass, which uses a positive (convex) lens to make things look bigger by allowing the user to hold them closer to their eye. * A telescope, which uses its large objective lens or primary mirror to create an image of a distant object and then allows the user to examine the image clo ...

Wilson Bentley
Wilson Alwyn Bentley (February 9, 1865 – December 23, 1931), also known as Snowflake Bentley, was an American meteorologist and photographer, who was the first known person to take detailed photographs of snowflakes and record their features. He perfected a process of catching flakes on black velvet in such a way that their images could be captured before they either melted or sublimated. Kenneth G. Libbrecht notes that the techniques used by Bentley to photograph snowflakes are essentially the same as those used today, and that while the quality of his photographs reflects the technical limitations of the equipment of the era, "he did it so well that hardly anybody bothered to photograph snowflakes for almost 100 years". The broadest collection of Bentley's photographs is held by the Jericho Historical Society in his home town, Jericho, Vermont. Bentley donated his collection of original glass-plate photomicrographs of snow crystals to the Buffalo Museum of Science. A ...

Amoeba
An amoeba (; less commonly spelled ameba or amœba; plural ''am(o)ebas'' or ''am(o)ebae'' ), often called an amoeboid, is a type of Cell (biology), cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopodia, pseudopods. Amoebae do not form a single Taxonomy (biology), taxonomic group; instead, they are found in every major Lineage (evolution), lineage of eukaryote, eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals. Microbiologists often use the terms "amoeboid" and "amoeba" interchangeably for any organism that exhibits amoeboid movement. In older classification systems, most amoebae were placed in the Class (biology), class or subphylum Sarcodina, a grouping of Unicellular organism, single-celled organisms that possess pseudopods or move by protoplasmic flow. However, molecular phylogenetic studies have shown that Sarcodina is not a monophyletic group whose memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vice (magazine)
''Vice'' (stylized in all caps) is a Canadian-American magazine focused on lifestyle, arts, culture, and news/politics. Founded in 1994 in Montreal as an alternative punk magazine, the founders later launched the youth media company Vice Media, which consists of divisions including the printed magazine as well as a website, broadcast news unit, a film production company, a record label, and a publishing imprint. As of February 2015, the magazine's editor-in-chief is Ellis Jones. History Founded by Suroosh Alvi, Gavin McInnes, and Shane Smith (the latter two being childhood friends), the magazine was launched in 1994 as the ''Voice of Montreal'' with government funding. The intention of the founders was to provide work and a community service. When the editors later sought to dissolve their commitments with the original publisher, Alix Laurent, they bought him out and changed the name to ''Vice'' in 1996. Richard Szalwinski, a Canadian software millionaire, acquired the magazi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wired (magazine)
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including '' Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ''Wired'' quickly became recognized ...

Smithsonian (magazine)
''Smithsonian'' is the official journal published by the Smithsonian Institution in Washington, D.C. The first issue was published in 1970. History The history of ''Smithsonian'' began when Edward K. Thompson, the retired editor of ''Life (magazine), Life'' magazine, was asked by the then-Secretary of the Smithsonian, S. Dillon Ripley, to produce a magazine "about things in which the Smithsonian [Institution] is interested, might be interested or ought to be interested." Thompson would later recall that his philosophy for the new magazine was that it "would stir curiosity in already receptive minds. It would deal with history as it is relevant to the present. It would present art, since true art is never dated, in the richest possible reproduction. It would peer into the future via coverage of social progress and of science and technology. Technical matters would be digested and made intelligible by skilled writers who would stimulate readers to reach upward while not turning the ...

Paper Project
The Paper Project is a fusion project that blends art, science, and technology into engaging 2D and 3D experiences. About the project The Paper Project is a multidimensional art and science project exploring the microscopic structure of paper using a scanning-laser confocal microscope. Created by artist and scientist Charles Kazilek and printer and paper maker Gene Valentine (July 29, 1938 – February 22, 2022) in 1999 the project began exhibiting works in various formats including 2D and virtual 3D images. The 3D anaglyphic images make use of inexpensive red-blue 3D glasses first introduced to moviegoers in the 1950s. When wearing 3D glasses, it is as if the viewer has been reduced to the size of a period at the end of a sentence and is able to explore the invisible structure and beauty of paper. In 2002, the project expanded to dance, collaborating with costume designers Jacqueline Benard and Galina Mihaleva and dance choreographer Jennifer Tsukayama. The result of the coll ...

History Of Photography
The history of photography began in remote antiquity with the discovery of two critical principles: camera obscura image projection and the observation that some substances are visibly altered by exposure to light. There are no artifacts or descriptions that indicate any attempt to capture images with light sensitive materials prior to the 18th century. Around 1717, Johann Heinrich Schulze captured cut-out letters on a bottle of a light-sensitive slurry, but he apparently never thought of making the results durable. Around 1800, Thomas Wedgwood made the first reliably documented, although unsuccessful attempt at capturing camera images in permanent form. His experiments did produce detailed photograms, but Wedgwood and his associate Humphry Davy found no way to fix these images. In 1826, Nicéphore Niépce first managed to fix an image that was captured with a camera, but at least eight hours or even several days of exposure in the camera were required and the earliest resul ...
