  • 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

  • Having set the background and gained a glimpse of just how thorny the subject could be it seems easiest to change tack and take the loosest of definitions. Listing some of the many things for which Ancient Rome might justly be remembered for....in no particular order: Advanced roads and road networks Milestones The standard width of our modern roads and tunnels is based on that of ancient Rome (there was a standard width for cart wheels, essentially based on the need of placing two horses side by side). The worn ruts in the roads made it virtually impossible to use any other measure. Triumphal arches Aqueducts (actually they learned much about structures from the Estruscans, but developed it to perfection) Bronze valves and water pumps. Huge numbers of instruments and tools for engineering, construction and measurement. The Romans were, after all, excellent engineers. For example you could purchase your access to water supply for set hours of the day or set quantities of water, which were dutifully metered and billed, pretty much as you would today, albeit with slighty different technology!. Medical and Surgical tools (mainly thanks to the Greeks actually but hugely developed as a consequence of the needs generated by Gladiatorial games and continuous war campaigns) Cesareans - sounds like Caesar doesn't it? Cesareans were often used to save the baby if the mother died during childbirth. Fast curing cement - hugely important discovery which allowed cement to cure and harden in short times and even under water. The ancient Romans realised that adding pozzolanic earth from volcanic regions (Eg Pozzuoli near Naples) to traditional mortar allowed a water proof and extremely solid mix. This could be used to waterproof the interior of aqueduct tunnels or extend the potentials of Roman architecture with impo

  • Now rats carried this disease off ships in Genoa. In just four years it killed off 40 percent of the people in Europe. It took three forms: "bubonic" plague hit the lymph system, "pneumonic" plague attacked the lungs, and "septicemic" plague assaulted the blood. But the words "Black Death" encompassed it all.
  • The Church-centered world before the plague had been oddly timeless. Now people worked long hours, chasing capital gain, in a life that could end at any moment. The first new technology of the plague years was time-keeping -- mechanical clocks and hourglasses. Medicine had been a function of the Church before the plague. Physicians were well-paid, highly-respected scholars. They spun dialectic arguments far away from unwholesome sick people -- not unlike some of today's specialists. 13th-century medicine, like the 13th-century Church, had failed miserably in coping with the plague. Both medical and religious practice now shifted toward the laity. Medicine was redirected into experimentation and practical pharmacology. Medical books were now being written -- not in Latin -- but in the vernacular, and by a whole new breed of people.

Kaffa Mongols Black Death Middle AGes

shared by Garth Holman on 05 Apr 18 - No Cached
  • Between 1347 and 1350, the Black Death raged through Medieval Europe. Historians and biologists have traced the origins of this deadly pandemic to the remote steppes of Central Asia. Plague had certainly erupted there by 1331 but how exactly did it spread from East to West? After ravaging Central Asia, the plague descended on China, India and Persia. In China alone, the plague killed around half of the human population. Despite such destruction, commercial activities continued unabated. This meant that the traders, their vessels and the rats aboard became the agents of infection. As they travelled along the established trade routes of the medieval world, they unwittingly carried the plague with them.
  • For several years, the Mongols had allowed a group of merchants from Genoa to control Kaffa, a bustling seaport on the Crimean Peninsula. This was highly advantageous for the Mongols as it provided a direct link to Italy’s largest commercial centre and encouraged trade across all corners of their vast empire. Tensions and disagreements, however, were a common feature of this commercial relationship, arising primarily from their religious differences; the Italians were devoutly Christian and the Mongols had been practising Muslims since the 1200s.

  • “Whereupon the Tartars (Mongols), worn out by this pestilential disease, and falling on all sides as if thunderstruck, and seeing that they were perishing hopelessly, ordered the corpses to be placed upon their engines and thrown into the city of Kaffa. Accordingly were the bodies of the dead hurled over the walls, so that the Christians were not able to hide or protect themselves from this danger, although they carried away as many as possible and threw them into the sea.”
  • summer of 1347, the Italian merchants headed to their ships and the fled the city of Kaffa. En route, however, the Italians stopped at Constantinople, inadvertently infecting the city. Thousands of people were killed, including Andronikos, the son of the Greek Emperor, John VI Cantacuzenos. Those who were able fled the city, many not realising that they were already infected. By the autumn, the western coast of Asia Minor was experiencing the full force of the Black Death and it would not be long before returned home to infect their native Italy.

Egypt Civilization

shared by jclenk on 10 Mar 22 - No Cached
  • This massive Arid climate makes it a strange place for a large population of people
  • It flows north through the Sahara creating a long oasis in the desert eventually dumping into the Mediterranean Sea
  • The Nile River is the world’s longest river
  • ...19 more annotations...
  • The Nile is divided into sections by cataracts.  A cataract is a rocky area that creates a waterfall or rapids.  There are six cataracts in the Nile river.
  •  As the water level lowered, it would leave behind rich fertile soil for farmers
  • Fresh water, irrigation, fertile soil--this is why people called it the "gift" of the Nile.
  • Around 6000 BCE the climate began to change, which might explain why many humans changed from hunting and gathering to farming.  Before civilization, early humans came to the Nile River to hunt, fish, and gather food, but gradually as people learned to farm and domesticate animals (about 7000 BCE and 5500 BCE), and therefore live in permanent settlements, areas around the Nile became more crowded.
  • The change from nomadic hunter-gatherers to civilized living followed the same pattern as other places around the world: farming provided extra food, which allowed the division of labor, which allows the development of government and religion and creates social classes. 
  • Historians call them Upper Egypt and Lower Egypt
  • We know so much about the Egyptians because there are so many written resources and because their culture lasted so long with few interruptions
  • Another reason we know so much about Egypt is because they made their architecture out of stone, which has lasted for the most part. 
  • Religion was a the center of Egyptian life.  Egyptians believed in many Gods, so they were polytheistic.
  • Later Egyptians would call their kings “pharaoh”.  Egyptian people believed the pharaoh was a living God, so the Egyptians developed a theocracy, or a government ruled by religious leaders.  This is important to understanding why Egyptian people were so willing to give their grain to the Pharaoh and build him or her incredible temples—they thought the Pharaoh was a living God that would be with them forever in eternity.
  • The most well-known ritual was mummification.  Egyptians believed in life after death, and they wanted the body to look life-like.  Anyone could be mummified if they had enough money
  • Egyptians were a very advanced civilization due to their inventions and technology.  Egyptians developed a writing system called hieroglyphs that combined pictures and symbols.  Eventually, they created an alphabet from their symbols.  In 1822 CE a European explorer found what is called the Rossetta Stone (left picture)--a stone with the same message written in 3 different languages, which finally allowed historians to translate ancient hieroglyphs. Egyptians developed a 365-day calendar and used a number system based on 10. Egyptians figured out amazing ways to cut stone to use in their temples and obelisks.  An obelisk is a tall narrow monument that becomes more narrow as it goes up.  They created a writing material similar to paper called papyrus from reeds found in the Nile.  Egyptians were excellent ship builders and excelled at mathematics.  They used fractions, decimals, addition, subtraction, multiplication, division and basic ideas of geometry.  Egyptian art and architecture is famous and has been reused and copied by many other civilization including Greece, Rome, and even the United States
  • Egyptian life depended on what social class you were a part of.
  • At the top of society was the Pharaoh.  Below the Pharaoh was the royal court (Pharaoh's family), high priests, government officials, and scribes and nobles (rich land owners).  Below them were doctors and engineers, craftsman, and then farmers and unskilled workers at the bottom.  Egyptians did use some slaves, but slavery is hardly mentioned in their writings.
  • Bread was the main food source, but they would have eaten meat during festivals. 
  • Egypt's history is divided into six different time periods
  • creating Egypt's first dynasty.  He defeated some enemies and united Upper and Lower Egypt into one civilization.
  • One of the first major Pharaohs of the Old Kingdom was Djoser.  His temple was one of the first pyramids Egyptians tried to build.  It was a "step pyramid" and it started the tradition of building pyramids as a burial ground for Pharaohs. Although the term "Pharaoh" wasn't used until much later, we will keep using it to refer to Egyptian kings.   
  • Hatshepsut was a women Pharaoh.  Her tomb is an amazingly long ramp leading to a temple that has been cut out of a mountain.  Pharaoh Akhenaten tried to start a new religious tradition of worshipping only one God.  Worshipping one God is called monotheism.  This did not sit well with the polytheistic population that has honored many gods for thousands of years.  After Akhenaten's death his monuments were destroyed and his name was removed from the list of kings. Years later he was often referred to as, "the enemy". Akhenaten's son would also become famous, thousands of years later when his tomb was found perfectly preserved. His name was Pharaoh Tutankhamen--he is known and King Tut. He became Pharaoh at age 9 or 10 and ruled for only 9 years.
