It is imprecise because no-one knows exactly at what date any of them first came into existence. It should also be noted that the earlier lathes were not made obsolete as soon as a new type came into existence. Indeed, examples of all of them can be found in very modern times. One aspect of the problem of dating is that no physical remains of the lathe itself have been found from before the 10th century AD, at the very earliest. The only evidence we have of the nature of early lathes is that of a documentary nature. The strap lathe Fig 4: Schematic diagram of a strap lathe tool rest not shown On these lathes the work-piece is held between two iron spikes supported by a crude wooden framework.

Oil on board, x 88 cm. Kunsthistorisches Museum, Vienna Compositional lines, sometimes referred to as implied lines, some examples of which have already been discussed above, are imaginary lines that are perceived as connecting two or more different lines, guiding the viewer’s eye in and around the composition.

Compositional lines can be both straight and curved. In almost every picture, Vermeer used compositional lines to unite distinct elements and imbue the picture with a greater sense of purpose. Vermeer’s late The Astronomer provides an interesting example of how the compositional line may be used as a structural and expressive tool. The horizontal line that represents the illuminated edge of the windowsill extends to the right connecting with the horizontal stand of the globe.

This line is continued by the upper edge of the figures ‘s extended arm and is finally picked up on the other side of the composition by the lower edge of the picture-within-a-picture. This imaginary line gives abstract structure to the composition and brings key elements of the picture into geometrical relation:

Iron Age Art BCE Paleolithic Pottery Up until the s, most archeologists and anthropologists believed that pottery was first made during the period of Neolithic art c. However, the discoveries at Xianrendong and Yuchanyan, together with the cache of Jomon pottery discovered at Odaiyamamoto I site 14, BCE at Aomori Prefecture, Japan, prove beyond doubt that ceramic pottery was being made ten thousand years earlier, during the European era of Solutrean art 20, , BCE – a surprising development given the relative absence of Chinese cave art during this period.

Moreover, with better dating techniques being developed, it is probable that we will find even older sites from the Middle period of the Upper Paleolithic. For primitive Stone Age cooking pots, all that was needed was a supply of clay and a source of heat. Thus most Chinese pottery of the Upper Paleolithic until about 10, BCE was roughly made earthenware, fired in bonfires for a short time at temperatures up to degrees Celsius. Vessels were made with round bottoms thus avoiding any sharp angles or rims that would be more prone to cracking.

Glazes were not used, while decoration was limited to the use of coiled “ropes” and basketry. In Japan, from about 14, BCE, the “Jomon” culture was named after the decorative technique of leaving impressions on the outside of the pot, by pressing rope into the clay before firing it. During the era of Chinese Neolithic art , however, the introduction of the potter’s wheel and better kilns, as well as the emergence of parallel technologies in smelting and metallurgy, helped to improve the range and quality of all types of ceramic ware.

Decoration was limited to simple designs applied by stamping and impressing techniques.

History as a Respectable Business Move on to stories with Chinese porcelain. If the silk had to play”, the porcelain case relatively simply and transparently official version creates the impression that before dating with China in 16 century, Europeans didn’t know and do porcelain couldn’t this misinformation is easily refuted, unbiased enough to familiarize themselves with any qualified written description of the history of European ceramics: This fact highlights the porcelain and silk among the mass of other”ancient Chinese inventions, which mostly surfaced in the second half of the 20 century Chinese silk in Europe were interested in not earlier than 18 century legend of Chinese origin of silk approved barely earlier 19 century the Chinese invention of.

Confidently assert that porcelain Chinese invented in unthinkable antiquity and for Millennium art in manufacturing reached a large porcelain tableware, figurines and other household and decorative items. In the 16 century Chinese porcelain was highly impressed the imagination of Europe, has become a matter of luxury and aristocratic prestige.

Aesthetic Movement Active in Britain during the s and s in both the fine and applied arts. Amounting to a reverence of pure beauty in art and design, its motto was ‘art for art’s sake’.

Oil on panel, 37 x National Gallery of Art, Washington D. Aerial perspective is a pictorial convention that enables the painter to create a forceful illusion of distance in a landscape by using paler colors sometimes tinged with blue , less pronounced tonal variation and vaguer forms to define those objects that are farthest from the viewer, especially near the horizon. The painterly technique replicates a natural phenomena that depends on the quantity of moisture in the air between the viewer and the objects.

In order to enhance the effect of aerial perspective, painters depicted foreground objects with sharp outlines, brilliant or warm colors that contrast with those reserved for the background. Aerial perspective had been firmly established as a mimetic device by the fifteenth century, and explanations of its effects were written by polymaths such as Leon Battista Alberti — and Leonardo da Vinci —

Sometimes the solution to a problem is staring you in the face all along. Chip maker Intel is betting that will be true in the race to build quantum computers—machines that should offer immense processing power by exploiting the oddities of quantum mechanics. But Intel is trying to adapt the workhorse of existing computers, the silicon transistor, for the task. This strategy makes Intel an outlier among industry and academic groups working on qubits, as the basic components needed for quantum computers are known.

No one has yet advanced silicon qubits that far. A quantum computer would need to have thousands or millions of qubits to be broadly useful, though. Another reason to work on silicon qubits is that they should be more reliable than the superconducting equivalents.

It might be an example of education with a simplified explanation that is a starter on the way to real science. It might introduce potential students to the understanding of the relativity and on the route towards the real science of theoretical astrophysics and relativity-physics. The Bishkek-formulation manages without complicated mathematics and is therefore easier to be understood than Einsteins field equations, on the theories of Lorentz, Poincare and others.

The Bishkek-formulation could be understood by a larger number of people who are interested in the relativity and astrophysics. It could create a significantly wider embedded support in the society for these fields of science.

Tucked away in a quiet corner of the applied sciences building at Delft University of Technology, the space is devoid of people. Buzzing with resonant waves as if occupied by a swarm of electric katydids, it is cluttered by tangles of insulated tubes, wires, and control hardware erupting from big blue cylinders on three and four legs. Inside the blue cylinders—essentially supercharged refrigerators—spooky quantum-mechanical things are happening where nanowires, semiconductors, and superconductors meet at just a hair above absolute zero.

National Gallery of Art , Washington, D. There is much to be said for the today’s state-of-the-art digital images of artworks. The level of detail and accuracy of color of the best digital images are such that they offer various advantages to viewing real works in museums, especially during temporary exhibitions when the proper display of the artworks can be seriously compromised by broader exhibition interests. Crowds, glare, dim light and the impossibility of examining paintings at close range to say nothing the inaccessibility of the important art collections to a great part of the world’s population are all factors that seriously inhibit the study and appreciation of many works of art.

For example, to expect Vermeer’s Guitar Player to reveal its nuanced beauty in the faint light of the barely illuminated Kenwood House where the picture is permanently housed is to ask too much any painting, whatever its artistic merit. However, viewing digital images of artworks present important lacunae in respects to the original art works they represent.

Jan Mayen Island has one exploitable natural resource, gravel , from the site at Trongskaret. Other than this, economic activity is limited to providing services for employees of Norway ‘s radio communications and meteorological stations located on the island. There are important fishing resources, and the existence of Jan Mayen establishes a large exclusive economic zone around it. A dispute between Norway and Denmark regarding the fishing exclusion zone between Jan Mayen and Greenland was settled in granting Denmark the greater area of sovereignty.

Significant deposits of petroleum and natural gas are suspected by geologists to lie below Jan Mayen’s surrounding seafloors. Since , Jan Mayen has been administered by the County Governor fylkesmann of the northern Norwegian county of Nordland to which it is closest. However, some authority over Jan Mayen has been assigned to the station commander of the Norwegian Defence Logistics Organisation, a branch of the Norwegian Armed Forces.
