Ancient Greek Inventions and Technology - Zapd - 1 views

  • There is conflict on who invented it but it is known that the ancient Greeks did in fact use it to measure distance.
  • The ancient Greeks discovered and used central heating in their more important temples. Flues (the small square holes seen in the picture) were put around the temple and circulated warm air from a fire somewhere else in the temple. After the fall of Ancient Greece central heating was mostly forgotten but was rediscovered in the industrial revolution.

  • Button, ornamental: Buttons—made from seashell—were used in the Indus Valley Civilization for ornamental purposes by 2000 BCE.[1] Some buttons were carved into geometric shapes and had holes pieced into them so that they could attached to clothing by using a thread.[1] Ian McNeil (1990) holds that: "The button, in fact, was originally used more as an ornament than as a fastening, the earliest known being found at Mohenjo-daro in the Indus Valley. It is made of a curved shell and about 5000 years old."
  • Calico: Calico had originated in the subcontinent by the 11th century and found mention in Indian literature, by the 12th century writer Hemachandra. He has mentioned calico fabric prints done in a lotus design.[3] The Indian textile merchants traded in calico with the Africans by the 15th century and calico fabrics from Gujarat appeared in Egypt.[3] Trade with Europe followed from the 17th century onwards.[3] Within India, calico originated in Calicut.[3] Carding, devices for: Historian of science Joseph Needham ascribes the invention of bow-instruments used in textile technology to India.[4] The earliest evidence for using bow-instruments for carding comes from India (2nd century CE).[4] These carding devices, called kaman and dhunaki would loosen the texture of the fiber by the means of a vibrating string.[4]
  • The words for "chess" in Old Persian and Arabic are chatrang and shatranj respectively — terms derived from caturaṅga in Sanskrit,[11][12] which literally means an army of four divisions or four corps.[13][14] Chess spread throughout the world and many variants of the game soon began taking shape.[15] This game was introduced to the Near East from India and became a part of the princely or courtly education of Persian nobility.[13] Buddhist pilgrims, Silk Road traders and others carried it to the Far East where it was transformed and assimilated into a game often played on the intersection of the lines of the board rather than within the squares.[15] Chaturanga reached Europe through Persia, the Byzantine empire and the expanding Arabian empire.[14][16] Muslims carried Shatranj to North Africa, Sicily, and Spain by the 10th century where it took its final modern form of chess.[15] Chintz: The origin of Chintz is from the printed all cotton fabric of calico in India.[17] The origin of the word chintz itself is from the Hindi language word चित्र् (chitr), which means a spot

  • Coherer, iron and mercury: In 1899, the Bengali physicist Jagdish Chandra Bose announced the development of an "iron-mercury-iron coherer with telephone detector" in a paper presented at the Royal Society, London.[19] He also later received U.S. Patent 755,840, "Detector for electrical disturbances" (1904), for a specific electromagnetic receiver. Cotton gin, single-roller: The Ajanta caves of India yield evidence of a single roller cotton gin in use by the 5th century.[20] This cotton gin was used in India until innovations were made in form of foot powered gins.[21] The cotton gin was invented in India as a mechanical device known as charkhi, more technically the "wooden-worm-worked roller". This mechanical device was, in some parts of India, driven by water power.[4] Crescograph: The crescograph, a device for measuring growth in plants, was invented in the early 20th century by the Bengali scientist Jagadish Chandra Bose.[22][
  • Perhaps as early as 300 BCE—although certainly by 200 CE—high quality steel was being produced in southern India also by what Europeans would later call the crucible technique.[24] In this system, high-purity wrought iron, charcoal, and glass were mixed in a crucible and heated until the iron melted and absorbed the carbon.[24] The first crucible steel was the wootz steel that originated in India before the beginning of the common era.[25] Archaeological evidence suggests that this manufacturing process was already in existence in South India well before the Christian era.[26][27][28][29] Dock (maritime): The world's first dock at Lothal (2400 BCE) was located away from the main current to avoid deposition of silt.[30] Modern oceanographers have observed that the Harappans must have possessed knowledge relating to tides in order to build such a dock on the ever-shifting course of the Sabarmati, as well as exemplary hydrography and maritime engineering.[30] This was the earliest known dock found in the world, equipped to berth and service ships.[30][31] It is speculated that Lothal engineers studied tidal movements, and their effects on brick-built structures, since the walls are of kiln-burnt bricks.[32] This knowledge also enabled them to select Lothal's location in the first place, as the Gulf of Khambhat has the highest tidal amplitude and ships can be sluiced through flow tides in the river estuar

  • Incense clock: Although popularly associated with China the incense clock is believed to have originated in India, at least in its fundamental form if not function.[33][34] Early incense clocks found in China between the 6th and 8th century CE—the period it appeared in China all seem to have Devanāgarī carvings on them instead of Chinese seal characters.[33][34] Incense itself was introduced to China from India in the early centuries CE, along with the spread of Buddhism by travelling monks.[35][36][37] Edward Schafer asserts that incense clocks were probably an Indian invention, transmitted to China, which explains the Devanāgarī inscriptions on early incense clocks found in China.[33] Silvio Bedini on the other hand asserts that incense clocks were derived in part from incense seals mentioned in Tantric Buddhist scriptures, which first came to light in China after those scriptures from India were translated into Chinese, but holds that the time-telling function of the seal was incorporated by the Chinese.[34] India ink, carbonaceous pigment for: The source of the carbon pigment used in India ink was India.[38][39] In India, the carbon black from which India ink is produced is obtained by burning bones, tar, pitch, and other substances.[39][40] Ink itself has been used in India since at least the 4th century BCE.[41] Masi, an early ink in India was an admixture of several chemical components.[41] Indian documents written in Kharosthi with ink have been unearthed in Xinjiang.[42] The practice of writing with ink and a sharp pointed needle was common in ancient South India.[43] Several Jain sutras in India were compiled in ink
  • Indian clubs: The Indian club—which appeared in Europe during the 18th century—was used long by India's native soldiery before its introduction to Europe.[45] During the British Raj the British officers in India performed calisthenic exercises with clubs to keep in for physical conditioning.[45] From Britain the use of club swinging spread to the rest of the world.[45] Kabaddi: The game of kabaddi originated in India during prehistory.[46] Suggestions on how it evolved into the modern form range from wrestling exercises, military drills, and collective self defense but most authorities agree that the game existed in some form or the other in India during the period between 1500-400 BCE.[46] Ludo: Pachisi originated in India by the 6th century.[47] The earliest evidence of this game in India is the depiction of boards on the caves of Ajanta.[47] This game was played by the Mughal emperors of India; a notable example being that of Akbar, who played living Pachisi using girls from his harem.[47][48] A variant of this game, called Ludo, made its way to England during the British Raj.[
  • Ruler: Rulers made from Ivory were in use by the Indus Valley Civilization in what today is Pakistan and some parts of Western India prior to 1500 BCE.[64] Excavations at Lothal (2400 BCE) have yielded one such ruler calibrated to about 1/16 of an inch—less than 2 millimeters.[64] Ian Whitelaw (2007) holds that 'The Mohenjo-Daro ruler is divided into units corresponding to 1.32 inches (33.5 mm) and these are marked out in decimal subdivisions with amazing accuracy—to within 0.005 of an inch. Ancient bricks found throughout the region have dimensions that correspond to these units.'[65] Shigeo Iwata (2008) further writes 'The minimum division of graduation found in the segment of an ivory-made linear measure excavated in Lothal was 1.79 mm (that corresponds to 1/940 of a fathom), while that of the fragment of a shell-made one from Mohenjo-daro was 6.72 mm (1/250 of a fathom), and that of bronze-made one from Harapa was 9.33 mm (1/180 of a fathom).'[66] The weights and measures of the Indus civilization also reached Persia and Central Asia, where they were further modified.[66] Seamless celestial globe: Considered one of the most remarkable feats in metallurgy, it was invented in Kashmir by Ali Kashmiri ibn Luqman in between 1589 and 1590 CE, and twenty other such globes were later produced in Lahore and Kashmir during the Mughal Empire.[67][68] Before they were rediscovered in the 1980s, it was believed by modern metallurgists to be technically impossible to produce metal globes without any seams, even with modern technology.[68] These Mughal metallurgists pioneered the method of lost-wax casting in order to produce these globes
  • Simputer: The Simputer (acronym for "simple, inexpensive and multilingual people's computer") is a self-contained, open hardware handheld computer, designed for use in environments where computing devices such as personal computers are deemed inappropriate. It was developed in 1999 by 7 scientists of the Indian Institute of Science, Bangalore, led by Dr. Swami Manohar in collaboration with Encore India, a company based in Bangalore.[69][70] Originally envisaged to bring internet to the masses of India, the Simputer and its derivatives are today widely utilized by governments of several Indian states as part of their e-governance drive, the Indian Army, as well as by other public and private organizations.[71][72] Snakes and ladders: Snakes and ladders originated in India as a game based on morality.[73] During British rule of India, this game made its way to England, and was eventually introduced in the United States of America by game-pioneer Milton Bradley in 1943.[73] Stepwell: Earliest clear evidence of the origins of the stepwell is found in the Indus Valley Civilization's archaeological site at Mohenjodaro in Pakistan.[74] The three features of stepwells in the subcontinent are evident from one particular site, abandoned by 2500 BCE, which combines a bathing pool, steps leading down to water, and figures of some religious importance into one structure.[74] The early centuries immediately before the common era saw the Buddhists and the Jains of India adapt the stepwells into their architecture.[74] Both the wells and the form of ritual bathing reached other parts of the world with Buddhism.[74] Rock-cut step wells in the subcontinent date from 200-400 CE.[75] Subsequently the wells at Dhank (550-625 CE) and stepped ponds at Bhinmal (850-950 CE) were constructed.[75] Stupa: The origin of the stupa can be traced to 3rd century BCE India.[76] It was used as a commemorative monument associated with storing sacred relics.[76] The stupa architecture was adopted in Southeast and East Asia, where it evolved into the pagoda, a Buddhist monument used for enshrining sacred relics.[76] Toe stirrup: The earliest known manifestation of the stirrup, which was a toe loop that held the big toe was used in India in as early as 500 BCE[77] or perhaps by 200 BCE according to other sources.[78][79] This ancient stirrup consisted of a looped rope for the big toe which was at the bottom of a saddle made of fibre or leather.[79] Such a configuration made it suitable for the warm climate of most of India where people used to ride horses barefoot.[79] A pair of megalithic double bent iron bars with curvature at each end, excavated in Junapani in the central Indian state of Madhya Pradesh have been regarded as stirrups although they could as well be something else.[80] Buddhist carvings in the temples of Sanchi, Mathura and the Bhaja caves dating back between the 1st and 2nd century BCE figure horsemen riding with elaborate saddles with feet slipped under girths.[81][82][83] Sir John Marshall described the Sanchi relief as "the earliest example by some five centuries of the use of stirrups in any part of the world".[83] In the 1st century CE horse riders in northern India, where winters are sometimes long and cold, were recorded to have their booted feet attached to hooked stirrups.[78] However the form, the conception of the primitive Indian stirrup spread west and east, gradually evolving into the stirrup of today.http://en.wikipe

Ancient Chinese Inventions - Top Discoveries and Inventions of the Ancient Chinese - 1 views

  • Tea has been so important in China that even the story of silk includes a probably anachronistic
  • cup of it. Legend says silk was discovered when a cocoon fell from a mulberry bush into a cup of imperial tea. This is similar to the legend of the discovery of tea where an emperor (Shen Nung (2737 B.C.)) drank a cup of water into which leaves from an overhanging Camellia bush had fallen. Tea, no matter what country it comes from, is from the Camellia sinensis plant. It seems to have been a new beverage in the third century A.D., a time when it was still regarded with suspicion, much as the tomato was when it was first brought to Europe. Today we refer to beverages as tea even though there is no real tea in them. (Purists call them tisanes.) In the early period, there was confusion, too, and the Chinese for tea was sometimes used to refer to other plants, according to Bodde.
  • The principle behind gunpowder was discovered by the Chinese in perhaps the first century A.D., during the Han Dynasty. It wasn't used in guns at the time, but created explosions at festivals.

  • The ancient Grecian Empire was not only known for its unprecedented warfare, it was also known for some of the inventors and inventions that took place during that time. Most of these inventions occurred during the fifth century B.C. but that was really only the start of the ancient Greek inventions that we have a record of. Some of the most well-known of these ancient Greece inventions occurred even after the Roman Empire had come into power.
  • It would be easy to discuss many of the ancient Greeks inventions that took place which were associated with warfare. Almost everybody is aware of the fact that Alexander the Great and his conquests were some of the most renowned throughout all history. In just a short period of time, he and his army overtook most of the then known world and if his life would not have been cut short, he would have continued his conquests. There were, no doubt, many ancient Greek inventions which helped to make his conquests successful. The one invention that I will discuss, however, is the canon. It is thought that they were one of the first to use a Canon although it did not use gunpowder. By using compressed air, these canons were able to hurl a projectile over long distances.

There were, no doubt, many ancient Greek inventions which helped to make his conquests successful. The one invention that I will discuss, however, is the canon.  It is thought that they were one of the first to use a Canon although it did not use gunpowder. By using compressed air, these canons were able to hurl a projectile over long distances.  One well-known ancient Greek invention is the Antikythera mechanism. Believe it or not, this was a type of calculator that is thought to have been invented some 2000 years ago. As a matter of fact, many people consider this to be the world's first computer, although it was nothing like the computers that we see today. Through the use of a complex system of gears, it was able to calculate the relative positions of the sun, moon and stars whenever a date was entered. This is one of the ancient Greeks inventions that was truly far ahead of its time. The ancient Greeks were also well known for their work that took place under water. Aristotle first described this type of contraption some 2400 years ago. It is thought that this is one of the ancient Greeks inventions that was used in order to salvage the floor of the ocean for various items. It is unknown what other applications this ancient Greek invention had but it was ingenious that they were able to come up with the concept.  Another one of the ancient Greek inventions that is rather interesting is that of the shower. Although nothing was known about germs at that particular time, the Greeks thought that it was a healthful practice to wash the body with water. The fact that there were showers during this time period is recorded in various art murals that have been excavated . It is hard to know what other ancient Greeks inventions were in existence during that time. One thing's for certain, they were a society that was rather enlightened and well ahead of their time. Perhaps with some more archaeology work on our part, we may be able to discover that they were behind some other ingenious ideas as well.
