ARROW Waveguide Example
An arrow is a fin-stabilized projectile launched by a bow. A typical arrow usually consists of a long, stiff, straight shaft with a weighty (and usually sharp and pointed) arrowhead attached to the front end, multiple fin-like stabilizers called fletchings mounted near the rear, and a slot at the rear end called a nock for engaging the bowstring. A container or bag carrying additional arrows for convenient reloading is called a quiver. The use of bows and arrows by humans predates recorded history and is common to most cultures. A craftsman who makes arrows is a fletcher, and one that makes arrowheads is an arrowsmith.Paterson ''Encyclopaedia of Archery'' p. 56 History The oldest evidence of likely arrowheads, dating to c. 64,000 years ago, were found in Sibudu Cave, current South Africa.Backwell L, d'Errico F, Wadley L.(2008).

Two Arrows
2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures. Evolution Arabic digit The digit used in the modern Western world to represent the number 2 traces its roots back to the Indic Brahmic script, where "2" was written as two horizontal lines. The modern Chinese and Japanese languages (and Korean Hanja) still use this method. The Gupta script rotated the two lines 45 degrees, making them diagonal. The top line was sometimes also shortened and had its bottom end curve towards the center of the bottom line. In the Nagari script, the top line was written more like a curve connecting to the bottom line. In the Arabic Ghubar writing, the bottom line was completely vertical, and the digit looked like a dotless closing question mark. Restoring the bottom line to its original horizonta ...

Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...

Mary Rose
The ''Mary Rose'' (launched 1511) is a carrack-type warship of the English Tudor navy of King Henry VIII. She served for 33 years in several wars against France, Scotland, and Brittany. After being substantially rebuilt in 1536, she saw her last action on 1545. She led the attack on the galleys of a French invasion fleet, but sank in the Solent, the strait north of the Isle of Wight. The wreck of the ''Mary Rose'' was located in 1971 and was raised on 11 October 1982 by the Mary Rose Trust in one of the most complex and expensive maritime salvage projects in history. The surviving section of the ship and thousands of recovered artefacts are of great value as a Tudor period time capsule. The excavation and raising of the ''Mary Rose'' was a milestone in the field of maritime archaeology, comparable in complexity and cost to the raising of the 17th-century Swedish warship '' Vasa'' in 1961. The ''Mary Rose'' site is designated under the Protection of Wrecks Act 1973 by statuto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biography George Cameron Stone was originally from Geneva, New York. He graduated in 1879 with a Bachelor of Philosophy from the Columbia School of Mines. In 1880, Stone became a member of the American Institute of Mining and Metallurgical Engineers (AIME). By 1882, Stone was employed as a mining engineer at the New Jersey Zinc and Iron Company. He was later promoted to chief engineer and chief metallurgist. Stone developed and held eight patents relating to the industrial application of metallurgy and published more than 50 articles on the subject as well.

Arctic Small Tool Tradition
The Arctic Small Tool tradition (ASTt) was a broad cultural entity that developed along the Alaska Peninsula, around Bristol Bay, and on the eastern shores of the Bering Strait around 2500 BC. ASTt groups were the first human occupants of Arctic Canada and Greenland. This was a terrestrial entity that had a highly distinctive toolkit based on microblade technology. Typically tool types include scrapers, burins and side and end blades used in composite arrows or spears made of other materials, such as bone or antler. Many researchers also assume that it was Arctic Small Tool populations who first introduced the bow and arrow to the Arctic, that eventually became the Eskimo archery material culture. ASTt camps are often found along coasts and streams, to take advantage of seal or salmon populations. While some of the groups were fairly nomadic, more permanent, sod-roofed homes have also been identified from Arctic Small Tool tradition sites. The Arctic Small Tool tradition include ...

Holmegård
Until 1 January 2007, Holmegaard was a municipality (Danish, '' kommune'') in Storstrøm County in the southern part of the island of Zealand (''Sjælland'') in south Denmark. The municipality covered an area of 66 km2, and had a total population of 7,442 (2005). Its last mayor was Søren Dysted, a member of the Social Democrats (''Socialdemokraterne'') political party.

Ahrensburg Culture
The Ahrensburg culture or Ahrensburgian (c. 12,900 to 11,700 BP) was a late Upper Paleolithic nomadic hunter culture (or technocomplex) in north-central Europe during the Younger Dryas, the last spell of cold at the end of the Weichsel glaciation resulting in deforestation and the formation of a tundra with bushy arctic white birch and rowan. The most important prey was the wild reindeer. The earliest definite finds of arrow and bow date to this culture, though these weapons might have been invented earlier. The Ahrensburgian was preceded by the Hamburg and Federmesser cultures and superseded by the Maglemosian and Swiderian cultures. Ahrensburgian finds were made in southern and western Scandinavia, the North German plain and western Poland. The Ahrensburgian area also included vast stretches of land now at the bottom of the North and Baltic Sea, since during the Younger Dryas the coastline took a much more northern course than today. The culture is named after a tunnel vall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...
