Mini Lisa
The ''Mini Lisa'' is a nanoscale replica of the ''Mona Lisa''. It was created in 2013 by Keith Carroll, a Georgia Institute of Technology PhD candidate, in order to demonstrate a technique called thermochemical nanolithography (TCNL) that was invented at the university. In TCNL, a tiny cantilever viewed through an atomic force microscope uses heat to activate a series of chemical reactions that create new molecules. Greater amounts of heat create more molecules which lighten the surface of the substrate, allowing a grayscale image to be created. The ''Mini Lisa'' is just wide, about a third the width of a human hair. It is roughly 1/25,000th the size of the ''Mona Lisa''. The ''Mini Lisa'' was created by making hundreds of individual points each wide. Carroll decided to recreate the ''Mona Lisa'' after a challenger claimed TCNL was not precise enough to create a work of art. He created an automated process to create any image desired based on a supplied heat map. The ''M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanoscopic Scale
The nanoscopic scale (or nanoscale) usually refers to structures with a length scale applicable to nanotechnology, usually cited as 1–100 nanometers (nm). A nanometer is a billionth of a meter. The nanoscopic scale is (roughly speaking) a lower bound to the mesoscopic scale for most solids. For technical purposes, the nanoscopic scale is the size at which fluctuations in the averaged properties (due to the motion and behavior of individual particles) begin to have a significant effect (often a few percent) on the behavior of a system, and must be taken into account in its analysis. The nanoscopic scale is sometimes marked as the point where the properties of a material change; above this point, the properties of a material are caused by 'bulk' or 'volume' effects, namely which atoms are present, how they are bonded, and in what ratios. Below this point, the properties of a material change, and while the type of atoms present and their relative orientations are still importan ...

Mona Lisa Replicas And Reinterpretations
Leonardo da Vinci's ''Mona Lisa'' is one of the most recognizable and famous works of art in the world, and also one of the most replicated and reinterpreted. ''Mona Lisa'' replicas were already being painted during Leonardo's lifetime by his own students and contemporaries. Some are claimed to be the work of Leonardo himself, and remain disputed by scholars. Prominent 20th-century artists such as Marcel Duchamp and Salvador Dalí have also produced derivative works, manipulating ''Mona Lisa'' image to suit their own aesthetic. Replicating Renaissance masterpieces continues to be a way for aspiring artists to perfect their painting techniques and prove their skills. Contemporary ''Mona Lisa'' replicas are often created in conjunction with events or exhibitions related to Leonardo da Vinci, for publicity. Her portrait, public domain and outside of copyright protection, has also been used to make political statements. Aside from countless print-reproductions of Leonardo's original ...

Mona Lisa
The ''Mona Lisa'' ( ; it, Gioconda or ; french: Joconde ) is a half-length portrait painting by Italian artist Leonardo da Vinci. Considered an archetypal masterpiece of the Italian Renaissance, it has been described as "the best known, the most visited, the most written about, the most sung about, the most parodied work of art in the world". The painting's novel qualities include the subject's enigmatic expression, the monumentality of the composition, the subtle modelling of forms, and the atmospheric illusionism. The painting has been definitively identified to depict Italian noblewoman Lisa Gherardini, the wife of Francesco del Giocondo. It is painted in oil on a white Lombardy poplar panel. Leonardo never gave the painting to the Giocondo family, and later it is believed he left it in his will to his favored apprentice Salaì. It had been believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. It was ...

Georgia Institute Of Technology
The Georgia Institute of Technology, commonly referred to as Georgia Tech or, in the state of Georgia, as Tech or The Institute, is a public research university and institute of technology in Atlanta, Georgia. Established in 1885, it is part of the University System of Georgia and has satellite campuses in Savannah, Georgia; Metz, France; Shenzhen, China; and Singapore. The school was founded as the Georgia School of Technology as part of Reconstruction plans to build an industrial economy in the post-Civil War Southern United States. Initially, it offered only a degree in mechanical engineering. By 1901, its curriculum had expanded to include electrical, civil, and chemical engineering. In 1948, the school changed its name to reflect its evolution from a trade school to a larger and more capable technical institute and research university. Today, Georgia Tech is organized into six colleges and contains about 31 departments/units, with emphasis on science and technology. I ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

Ansel Adams
Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed an exacting system of image-making called the Zone System, a method of achieving a desired final print through a deeply technical understanding of how tonal range is recorded and developed during exposure, negative development, and printing. The resulting clarity and depth of such images characterized his photography. Adams was a life-long advocate for environmental conservation, and his photographic practice was deeply entwined with this advocacy. At age 12, he was given his first camera during his first visit to Yosemite National Park. He developed his early photographic work as a member of the Sierra C ...
