Edgar Lissel
Edgar Lissel (born 1965 in Northeim, Germany) is a visual artist. He studied photography at the University of Applied Sciences Darmstadt. Since 1993 he has been working as a visual artist. In his interdisciplinary projects he searches for traces of the tension between natural science, archeology, arthistory and artistic work while examining pictorial processes and the ephemeral state of images. In his early works Edgar Lissel has been using the camera obscura and converted a transporter into a mobile pinhole camera. With his works about the italian fascism and the German national socialism he has been invited to the Venice Architecture Biennale in 1996. His works "Räume“ are based around living quarters and museum displays which he converted into walk-in pinhole cameras. Simple optical principles combine the upside down scene outside the pinhole camera with the silhouettes of the objects inside the camera. Since 1999, Edgar Lissel has been working with bacteria, using their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northeim
Northeim (; nds, Nuurten) is a town in Lower Saxony, Germany, seat of the district of Northeim, with, in 2011, a population of 29,000. It lies on the German Half-Timbered House Road. History Northeim is first mentioned in 800 in a document recording a property transfer by a Frankish nobleman to the Abbey of Fulda. In the 10th century the surrounding region became a county, administered by the Counts of Northeim. The first of them, Siegfried is mentioned in 982. From 1061 to 1070 Count Otto II held the stem duchy of Bavaria as an Imperial fief, but lost it again because of his involvement in the Saxon plot against King Henry IV. The monastery of St. Blasius was founded around 1100. In 1252 Northeim obtained town rights, and from 1384 to 1554 it was a member of the Hanseatic League. When protestantism was introduced in 1532 all the churches were allocated to the protestants. The town became part of the Kingdom of Hanover. A part of Northeim was devastated by a fire in 1832 w ...

Ephemeral
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Obscura
A camera obscura (; ) is a darkened room with a aperture, small hole or lens at one side through which an image is 3D projection, projected onto a wall or table opposite the hole. ''Camera obscura'' can also refer to analogous constructions such as a box or tent in which an exterior image is projected inside. Camera obscuras with a lens in the opening have been used since the second half of the 16th century and became popular as aids for drawing and painting. The concept was developed further into the photographic camera in the first half of the 19th century, when camera obscura boxes were used to exposure (photography), expose photosensitivity, light-sensitive materials to the projected image. The camera obscura was used to study eclipses without the risk of damaging the eyes by looking directly into the sun. As a drawing aid, it allowed tracing the projected image to produce a highly accurate representation, and was especially appreciated as an easy way to achieve proper grap ...

Pinhole Camera
A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called ''pinhole'')—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect. The size of the images depends on the distance between the object and the pinhole. History Camera obscura The camera obscura or pinhole image is a natural optical phenomenon. Early known descriptions are found in the Chinese Mozi writings (circa 500 BCE) and the Aristotelian ''Problems'' (circa 300 BCE – 600 CE). Ibn al-Haytham (965–1039), an Arab physicist also known as Alhazen, described the camera obscura effect. Over the centuries others started to experiment with it, mainly in dark rooms with a small opening in shutters, mostly to study the nature of light and to safely watch solar eclipses. Giambattista Della Porta wrote in 1558 in his Magia Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Socialism
Nazism ( ; german: Nazismus), the common name in English for National Socialism (german: Nationalsozialismus, ), is the far-right politics, far-right Totalitarianism, totalitarian political ideology and practices associated with Adolf Hitler and the Nazi Party (NSDAP) in Nazi Germany. During Hitler's rise to power in 1930s Europe, it was frequently referred to as Hitlerism (german: Hitlerfaschismus). The later related term "neo-Nazism" is applied to other far-right groups with similar ideas which formed after the Second World War. Nazism is a form of fascism, with disdain for liberal democracy and the parliamentary system. It incorporates a dictatorship, fervent antisemitism, anti-communism, scientific racism, and the use of eugenics into its creed. Its extreme nationalism originated in pan-Germanism and the ethno-nationalist ''Völkisch movement, Völkisch'' movement which had been a prominent aspect of German nationalism since the late 19th century, and it was strongly i ...

Venice Architecture Biennale
Venice Biennale of Architecture (in Italian Mostra di Architettura di Venezia) is an international exhibition of architecture from nations around the world, held in Venice, Italy, every other year. It was held on even years until 2018, but 2020 was postponed to 2021 due to the COVID-19 pandemic shifting the calendar to uneven years. It is the architecture section under the overall Venice Biennale and was officially established in 1980, even though architecture had been a part of the Venice Art Biennale since 1968. The main agenda of the Architecture Biennale is to propose and showcase architectural solutions to contemporary societal, humanistic, and technological issues. Although leaning towards the academic side of architecture, the Biennale also provides an opportunity for local architects around the world to present new projects. The Biennale is separated into two main sections: The permanent, national pavilions in the Biennale Gardens as well as the Arsenale, which hosts ...

Silhouette
A silhouette ( , ) is the image of a person, animal, object or scene represented as a solid shape of a single colour, usually black, with its edges matching the outline of the subject. The interior of a silhouette is featureless, and the silhouette is usually presented on a light background, usually white, or none at all. The silhouette differs from an line art, outline, which depicts the edge of an object in a linear form, while a silhouette appears as a solid shape. Silhouette images may be created in any visual artistic medium, but were first used to describe pieces of cut paper, which were then stuck to a backing in a contrasting colour, and often framed. Cutting portraits, generally in profile, from black card became popular in the mid-18th century, though the term ''silhouette'' was seldom used until the early decades of the 19th century, and the tradition has continued under this name into the 21st century. They represented a cheap but effective alternative to the portrai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phototropic
Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Negative phototropism is not to be confused with skototropism which is defined as the growth towards darkness, whereas negative phototropism can refer to either the growth away from a light source or towards the darkness. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth.Goyal, A., Szarzyns ...

Domus Aurea
The Domus Aurea (Latin, "Golden House") was a vast landscaped complex built by the Emperor Nero largely on the Oppian Hill in the heart of ancient Rome after the great fire in 64 AD had destroyed a large part of the city.Roth (1993) It replaced and extended his Domus Transitoria that he had built as his first palace complex on the site. History The Domus Aurea was probably never completed. Otho and possibly Titus allotted money to finish at least the structure on the Oppian Hill; this continued to be inhabited, notably by emperor Vitellius in 69 but only after falling ill, until it was destroyed in a fire under Trajan in 104. A symbol of decadence that caused severe embarrassment to Nero's successors, the Domus Aurea was stripped of its marble, jewels, and ivory within a decade. Although the Oppian villa continued to be inhabited for some years, soon after Nero's death other parts of the palace and grounds, encompassing 2.6 km2 (c. 1 mi2), were filled with earth a ...

Skin Flora
Skin flora, also called skin microbiota, refers to microbiota (communities of microorganisms) that reside on the skin, typically human skin. Many of them are bacteria of which there are around 1,000 species upon human skin from nineteen phyla.Pappas S. (2009)Your Body Is a Wonderland ... of Bacteria ScienceNOW Daily News Most are found in the superficial layers of the epidermis and the upper parts of hair follicles. Skin flora is usually non-pathogenic, and either commensal (are not harmful to their host) or mutualistic (offer a benefit). The benefits bacteria can offer include preventing transient pathogenic organisms from colonizing the skin surface, either by competing for nutrients, secreting chemicals against them, or stimulating the skin's immune system. However, resident microbes can cause skin diseases and enter the blood system, creating life-threatening diseases, particularly in immunosuppressed people. A major non-human skin flora is ''Batrachochytrium dendrobatid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
