Sustainable Schools And Public Buildings Concrete Masonry'S: Fill & Download for Free

In short, I think it has as much to do with the building materials as it does the architectural design. Here is a great article on the latest in earthquake-resistant materials.Researchers Develop Earthquake-Resistant ConcreteBy Michael J. MarquisIn cities and towns prone to earthquakes, building codes require specific tests for any masonry used to construct new buildings. In California, for example, brick walls must meet code specification for facing, bonding and distance between headers. Wall anchors are tested and must adhere to strict coding requirements. With that being said, older buildings in California have yet to be retrofitted – leaving it up to the owners to do so. This process is not only costly but rather complicated depending upon the type of building.UBC’s Earthquake-Proof ConcreteThere may be a solution. Thanks to a group of Canadian researchers at the University of British Columbia, there’s a new way to retrofit buildings with an earthquake-proof material that is coated on existing walls. Capable of withstanding a 9.0 to 9.1 magnitude earthquake (similar to the Tohoku, Japan quake in 2011), UBC’s new groundbreaking mixture fortifies existing concrete walls that would normally crumble under the duress of a powerful seismic event.The “seismic-resistant, fiber-reinforced concrete,” according to a recent press release from UBC is “similar to steel, designed to be strong, malleable, and ductile.” Called eco-friendly ductile cementitious composite (EDCC), the cutting-edge mixture can be easily applied to the surface of an existing wall – making it earthquake-resistant. This rather innovative mixture is designed for one purpose: to save lives.Eco-Friendly Ductile Cementitious Composite (EDCC)“We sprayed a number of walls with a 10 millimeter-thick layer of EDCC, which is sufficient to reinforce most interior walls against seismic shocks,” says Salman Soleimani-Dashtaki, a Ph.D. candidate in the department of civil engineering at UBC. “Then we subjected them to Tohoku-level quakes and other types and intensities of earthquakes—and we couldn’t break them.”EDCC combines cement with polymer-based fibers, flyash, and other industrial additives, making it highly sustainable, according to UBC civil engineering professor Nemy Banthia, who supervised the work. In initial lab tests, the 10 mm-thick layer of EDCC was applied to walls made of traditional concrete blocks. After going through rigorous earthquake testing, which involved simulating a 9.1-magnitude seismic event, the EDCC walls help up without any crumbling. That was not the case for the concrete walls without the EDCC. They turned into rubble almost immediately.Cement Production and Greenhouse Gas EmissionsWith close to 70% of the composite made of Flyash, an industrial by-product, not only is the EDCC material the perfect strengthening substance for buildings in earthquake-prone cities, but it also reduces the harmful greenhouse gases normally produced when manufacturing concrete. It’s a win-win for everyone involved. “By replacing nearly 70% of cement with flyash, an industrial byproduct, we can reduce the amount of cement used,” said Banthia. “This is quite an urgent requirement as one ton of cement production releases almost a ton of carbon dioxide into the atmosphere, and the cement industry produces close to seven percent of global greenhouse gas emissions.”“This UBC-developed technology has far-reaching impact and could save the lives of not only British Columbians but citizens throughout the world,” said Advanced Education, Skills, and Training Minister Melanie Mark. “The earthquake-resistant concrete is a great example of how applied research at our public universities is developing the next generation of agents of change. The innovation and entrepreneurship being advanced at all of our post-secondary institutions is leading to cutting-edge technologies and helping to create a dynamic, modern B.C. economy that benefits all of us.”EDCC’s Real-World ApplicationThe first project on the docket for the team at the University of British Columbia: applying EDCC to the walls of Dr. Annie B Jamieson Elementary School located in Vancouver. The cutting-edge research was funded by the UBC-hosted Canada-India Research Centre of Excellence IC-IMPACTS, which promotes research collaboration between Canada and India. IC-IMPACTS will make EDCC available to retrofit a school in Roorkee in Uttarakhand, a highly seismic area in northern India.“This technology is gaining significant attention in India and will provide our Canadian companies a strong competitive edge in the growing global infrastructure market,” added Banthia, who also serves as IC-IMPACTS scientific director.Other EDCC applications include resilient homes for First Nations communities, pipelines, pavements, offshore platforms, blast-resistant structures, and industrial floors.Safeguard Your Home with ConcreteIn light of the most destructive wildfire in California’s history (destroying at least 5,700 buildings and counting) and the catastrophic damage caused by Hurricane Harvey (damaging 185,149 homes in Texas), moving away from the traditional wood frame construction in favor of reinforced concrete may be a wise decision, especially if your property is vulnerable to severe weather conditions or forest fires.Source: University of British Columbia, New Atlas

Why did houses collapse?Settlements in the Tronto Valley have built up over centuries, along the route of an important ancient Roman road, the Via Salaria.Primarily made of stone, homes were built without the benefit of modern science and renovated more recently with new materials, sometimes with disastrous results."When reinforced concrete is used on the roof, its weight causes the masonry to fail because the walls beneath cannot sustain it," says Graziano Leoni, a professor of structural engineering at the University of Camerino, who has been helping assess damage to buildings.In Arquata del Tronto, lumps of concrete can be seen in the wrecks of the buildings, with old stone walls burst open like seed pods.Another factor may have been the close proximity of buildings of different ages, the professor believes.Residents of the valley also fear buildings may have been damaged by loosened rocks or rubble left over from a 6.1 magnitude earthquake that hit the Umbria and Marche regions in 1997.Image copyrightANTONIO FILIPPINIImage captionMuch of Arquata del Tronto has become a no-go areaImage captionBut the local school's modern construction saved itTwo schools in the quake zone suffered different fates. Despite the widespread destruction in Arquata, the village school withstood the shock because of its solid brick-and-mortar construction, although the damage was enough for it to be rendered unusable.But that was not the case in Amatrice, Lazio, where the supposedly earthquake-proof school collapsed, leading to suspicions of shoddy public construction.

Q: Where can we get ancient Indian engineering and technological details?Indian civilization is a story of scientific and technological prowess over a long period of time in domains spanning architecture, mathematics, metallurgy, medicine, farming, water management, ship building and navigation, and many more.However, as is the case with history of other domains, the details of Indian engineering and technology over the centuries, if not millennia, are not available at one place.In this answer I would quote excerpts from the works of Rajiv Malhotra | Infinity Foundation topoint to some of the works detailing the history of Indian science and technology,and elaborate why it is important to explore the history of science, and in particular the history of Indian technological achievements.Besides India's philosophical and cultural legacy, its scientific heritage needs to be understood in order to give its people a realistic sense of their place in the world. This aim is not inspired by chauvinism, but by the need to better comprehend the genius of Indian Civilization, and by the need to provide a fresh and vital voice in the global community.Some books to read on Indian Science and Technology:Reflections on The History of Indian Science and Technology - OC HandaHarappan Architecture and Civil Engineering: Contributions to History of Indian Science and Technology - Jagat Patil JoshiHarappan Technology and Its Legacy - DP AgrawalHistory of Iron Technology in India - Vibha TripathiMarvels of Indian Iron: Through the Ages - Balasubramaniam R.Chalcolithic South Asia Aspects of Crats and Technologies - Vasant SjhindeIndian Zinc Technology in a Global Perspective - JS KharakwalHistory of Metals:: In Eastern India and Bangladesh - Pranab K.

Multi-polar historical perspectives in the globalized world:Since the dawn of history, different peoples have contributed to different branches of science and technology, often through interactive contacts across cultures separated by large distances. This interactive influence is becoming clearer as the vast extent of pre-colonial global trade and cultural migration is being properly understood by researchers. However, one finds a mainly Eurocentric perspective in the teaching of the history of science. Typically, it starts with Greece, neglecting the influences of others upon Greece. Then it 'fast forwards' many centuries into 1500 CE to claim modern science as an exclusively European triumph, neglecting the influence of others (especially India) on the European Renaissance and the Enlightenment. The European Dark Ages are presumed to be dark worldwide, when, in fact, other regions saw innovation and prosperity. In fact, Europe was at the peripheries, until the conquest of America in 1492.With the entrenchment of colonialism, the contribution made by others, including India, was ignored. The British colonizers could never accept that Indians were highly civilized as far back as the third millennium BCE when the British were still in a barbarian stage. Such acknowledgment would destroy Europe's intellectual premise for colonization – its civilizing mission. Early British scholars documented Indian thought and its external manifestations as systems competing with their own and thus facilitated the transfer of technology into what became known as Britain's Industrial Revolution. What was found valuable was quickly appropriated and its Indian manufacturers were forced out of business, often through draconian laws enacted by the British. This was, in many instances, justified as civilizing them. Meanwhile, a new history of India was fabricated to ensure that generations of mentally colonized people would believe in the inherent inferiority of their own traditional knowledge. This has been called Macaulayism, named after Thomas Macaulay, the civil servant who became the most prominent champion of such British cultural imperialism strategy starting in the 1830s.When it became difficult for Europeans to ignore the massive archaeological evidence of classical Indian science and technology, they asserted that the Indus-Sarasvati Civilization had to be a transplant from the Egyptian and Mesopotamian civilizations. These constructions in historiography have been cumulative rather than re-constructive: more theoretical layers are constructed to explain new contradictory data rather than prior ones being re-examined or corrected. Unfortunately, despite Indian independence there has not been much effort at correcting these distortions. Many among India's intellectual elite continue to promote the notion that pre-colonial India was feudalistic, pre-rational, and, by implication, in need of being invaded for its own benefit.This has created a climate in which entrenched prejudice against non-Western knowledge persists. Even after independence, an institutional bias against traditional technologies continues.It is important to note that among all the conquered and colonized civilizations of the Old World, India is unique in the following respect: its wealth was industrial and created by its workers' ingenuity and labor. In the case of the Native Americans, the plunder by the colonizers was mainly of land, gold and other natural assets. In the case of the Africans, the plunder was both of natural assets and of slave labor. But in India's case, the colonizers had a windfall – extraordinary profit margins from the control of India's exports, the taxation of its economic production, and eventually the transfer of its technology and production to the colonizer's home.This comprised an immense transfer of wealth out of India to Europe. From being the world's major exporting economy (along with China), India was reduced to an importer of goods; from being the source of much of the economic capital that funded Britain's Industrial Revolution, it became one of the biggest debtor nations; from its envied status as one of the wealthiest nations, it became a land synonymous with poverty; and from a nation with a large number of prestigious centers of higher education that attracted the cream of foreign students from Asia, it became the land with the highest number of illiterate persons. This remains a major untold story. The West has failed to recognize that its position of power was gained not by its inherent superiority but by the fact that it was successful in trampling over others.The justification for this gross exploitation and denigration of colonial victims was known as the civilizing mission. The colonial powers argued that in exchange for the wealth they plundered, both material and intellectual, they were providing the colonized people an opportunity to ‘modernize'. But, first, they had to create the perception that the West held all the keys to progress and that it was benevolently willing to share its gifts with the world. This perception was manufactured by Eurocentric historiographies and the manipulation, distortion, and concealing of historical data. In the Indian context, colonial Indologists were required to create a portrayal of India as a region that was backward and in need of colonial stewardship.After independence, many Indian intellectuals continued to use the pre-colonial, feudalistic framework of Indian society. In contrast, Arab scholars have brought out the important role of Islamic empires in the transmission of ideas into Europe. However, many discoveries and innovations of India, as acknowledged by the Arab translators themselves, are now often depicted as being of Arab origin, when in fact, the Arabs often retransmitted what they had learnt from India over to Europe.In the case of China, Joseph Needham, a leading scholar at Cambridge, made it his life's work to document China's history of science and technology in over 30 volumes. By the time he died at age 90, his works had transformed the study of China forever. The Needham Foundation has continued this monumental work, and has been expanding the series with new volumes. Today, every research library on China, and every major library on science and history, has the Needham collection as important reference. Every serious China scholar respects this work, and its impact on the perception of China has been phenomenal. This impact has also trickled down to depictions in schools and the general media.Unfortunately, India is yet to achieve this kind of intellectual repositioning. It continues to be depicted through “caste, cows and curry” images all too often. Indian culture is frequently portrayed as being mystical in the sense of being irrational, and in lacking a sense of advancement in the material plane of society. Often, many Westernized Indians internalize these colonial stereotypes. Amartya Sen expressed his views on this as follows:“Fear of elitism did not, happily, deter Joseph Needham from writing his authoritative account of the history of science and technology in China, and to dismiss that work as elitist history would be a serious neglect of China's past…“A similar history of India's science and technology has not yet been attempted, though many of the elements have been well discussed in particular studies. The absence of a general study like Needham's is influenced by an attitudinal dichotomy. On the one hand, those who take a rather spiritual – even perhaps a religious – view of India's history do not have a great interest in the analytical and scientific parts of India's past, except to use it as a piece of propaganda about India's greatness (as in the bloated account of what is imaginatively called ‘Vedic mathematics', missing the really creative period in Indian mathematics by many centuries). On the other hand, many who oppose religious and communal politics are particularly suspicious of what may even look like a ‘glorification' of India's past. The need for a work like Needham's has remained unmet (Sen, 1997: 32).”2. Competing globally requires intellectual decolonization:Facts contradict the following prevailing stereotypes:India was less rational and scientific than the West.India was world negating in its outlook, frozen in time and unable to advance without help from foreign invaders.India's civilization was mainly imported via invaders, except for its problems such as caste that were its own 'essences'.Indian society was socially backward (to the point of being seen as lacking in morality), hence dependent upon Westernization to reform its current problems.This should lead to the following introspection: Is India a 'developing' society, or is it a 'redeveloping' society? Were Indians always poor, always living in polluted and socially problematic conditions, and are these problems Indian essences? Or is there a history behind its present sociopolitical adversities? This history should not, however, excuse the failures of 50 years of independence to deal with the economic and social problems that persist.Indians need to overhaul their own assessment of their potential. Is India meant to be a nation dependent on importing technology and intellectual property, as we have been told for so long? Or is India meant to be a nation of exporters of technology and intellectual property, as Infinity Foundation believes?The implications are staggering. The choices are dramatic and opposite:Should India upgrade its higher education in order to compete globally as an intellectual place of learning, competing with the West's best universities for the multi-billion dollar education industry? This would be a return to India's role in classical times, when its viharas (intellectual hubs) such as Nalanda and Taxashila attracted the cream of Asia's scholars much like Ivy League institutions in the United States do now.Or should India continue to depend on Western higher education for its paradigms, frameworks, research and development, certification of competence and credibility, careers and legitimacy for its brightest youth?China has embarked on a massive upgrade of its universities in order to export higher education to the third world. Its strategy is not driven by short-term economic income but by a long-term ambition to counter the West by spreading its own influence to the next generation of thinkers worldwide. These bold moves cannot come out of inferiority complexes, such as those that plague many educated Indians today.Until the 1800s, traditional knowledge generated large-scale economic productivity for Indians. It was the thriving Indian economy that attracted so many waves of invaders, culminating with the British. Traditionally, India was one of the richest regions in the world, and most Indians were neither 'backward' nor uneducated or poor. Some historians have recently begun to demonstrate that it was economic drainage, oppression, social re-engineering at the hands of colonizers that made millions of 'new poor' over the past few centuries. This explanation yields a radically different reading of the poverty in India today. Upon acknowledging India's traditional knowledge systems, one is forced to discard accounts of its history that essentialize its poverty and related social evils.Contemporary India's outsourcing industries and its ability to attract investments also depend on unstated, and often unconscious, impressions about India as a place to do business and about Indian culture. Since India sees itself as a global power, or at least a regional power, it must also embark on intellectually repositioning its brand – away from being seen as the center of human rights abuses, naked sadhus, exotica and erotica. There is no better place to start than via its long track record in science and technology.It is often said that Indians' recent excellent performance in the global economy – as medical doctors, information technologists, financial experts, corporate managers – must be the positive effect of colonialism. One hears even Indians internalize explanations of their success as being the result of colonizers teaching them “rational thought”, English, democracy, and so forth. An honest account of the history of ideas would make such Western chauvinism untenable. For example, one might raise the following objections:Prof Fritz Staal, a well known Indologist, explains the relevance of Indian thought in today's leading-edge research areas in an article titled, “Artificial Intelligence: Asian backgrounds or influences.” (See: http://www.iias.nl/iiasn/30/IIASNL30_15.pdf )If learning the colonizer's language and customs were the cause for Indians becoming scientific minded, then why are most African, Latin American and many other third world former European colonies not able to develop as fast as India has done? The fact is China's and India's development should be seen not as development but as re-development, meaning that these civilizations' very fabrics have a culture of advancement through rational thought for millennia, and they are now reviving their innate capabilities that had become dormant and/or suppressed.Al-Beruni and other visitors recorded centuries ago that Indians were among the leading medical practitioners, researchers and educators in the Middle East. Records in China support these claims. Indians pioneered in various fields of mathematics, metallurgy, agriculture, medicine, shipping and trade, language. India was the mother of pan-Asian civilizations in certain ways just as Greece was the mother of European civilization. This Indian influence on East and Southeast Asia is acknowledged by those societies today and is well-documented in their own writings, but not in the writings by European writers where Indian sources are often marginalized.3. Social reasons:The rapidly-expanding, globalizing economy is built largely on Western lifestyles and is homogenizing human 'wants' in unachievable ways. Across the world, people are being forced to accept that progress, success and modernity are synonymous with Westernization. Those 'left behind' are made to feel like failures when measured against this standard. However, this promise of universal Westernization is simply unachievable. There are several reasons why:The capital required for universal Western-style development simply does not exist in the world, and the trickle down effect of free markets is too slow to reach the bottom tiers where most people live.Western civilization depends upon inequality (in the form of cheap labor) and massive natural resources, which is eventually unsustainable sociologically or ecologically. The global capitalist system in some ways stands in contradiction to individual rights, which it promotes in theory. For instance, a free market of labor would involve free movement of workers across international borders, but this would threaten the artificially high wages of Western citizens.The bulk of labor in the non-Western world is outside the framework of globalization and development. Significantly, today less than 10 per cent of India's labor works in the 'organized sector', namely as employees of a company. The remaining 90 per cent comprises freelances, contract laborers, private entrepreneurs, and so on. Many of them still practice traditional, non-Westernized trades. Indian colonial law continues to render much of their work illegal, making them highly vulnerable to exploitation, corruption, and abuse. The descendants of India's traditional knowledge workers, who built massive cities, who had highly developed and researched technologies, and who dominated world trade for centuries, are today de-legitimized in their own country. Many of today's poor jatis, such as workers in textile, masonry and metal works, were at one time the empowered guilds that supplied the world with highly-prized manufacture.The Western economic development model demands relentless growth to sustain equity valuations in the financial markets, and yet growth cannot be indefinite once population stabilizes. A steady state economy in zero-growth equilibrium would devastate the wealth of the West, since all financial valuations are predicated on growth. Thus, there is a vested interest for the West to push its technologies without looking to the extended future. Even if the world's six billion persons (anticipated to grow to ten billion by the middle of this century) were to magically achieve Western lifestyles, this would be temporary because of limits to the planet's natural resources. When Gandhi was asked whether he would like India to develop a lifestyle similar to England's, his reply may be paraphrased as follows: The British had to plunder the Earth to achieve their lifestyle. Given India's much larger population, it would require the plunder of many planets to achieve the same.The West controls the institutions, standards, socio-economic categories and laws (such as the notions of 'property' and 'justice' which originated from Biblical concepts) on which the global system is based. The non-West is thus inherently disadvantaged. The West will be able to accommodate a relatively small percentage of non-Westerners as honorary Westerners, to serve as middlemen in managing and containing the non-Western masses, in exchange for enjoying Western privileges.Western lifestyle is built on inequality. Cheap labor, cheap natural resources, and blights like industrial pollution and environmental degradation must be exported to the third world facilitate this lifestyle. For Western lifestyle to exist, poverty and deprivation must also exist somewhere in the world. Many in the West show awareness and concern for the ‘Other' but are unable to identify these problems as natural implications of Western lifestyle.Many traditional knowledge systems are relevant to economic planning today, because they are eco-friendly, sustainable, labor-intensive, rather than capital intensive. Implementation of traditional technologies should be done in parallel with top down ‘modern' scientific development. For example:Water is one of the more serious problem areas of India and many other parts of the world. There was an ancient Indian system of talabs (water tanks) in every village. They were designed to collect and store rainwater for irrigation and for drinking. It was a function of the village panchayat to maintain and administer these water tanks. However, under colonial rule, village governance was subverted or abandoned, since the goal was to maximize tax collection through a network of British-appointed “district collectors”. As native social structures were abandoned, many talabs went into disuse or misuse. Today, satellite pictures show only traces of what was once a massive network of man-made lakes.This indigenous system scores over modern dams that are centrally managed and possible ecological hazards. In parts of Tamil Nadu and Rajasthan, many of these old talabs have been excavated and revived, alleviating, to a degree, water scarcity.Indians were the first to develop steel, and the famous Delhi Iron Pillar is the world's oldest extant rust-free sample of steel, having lasted 16 centuries. Leading metallurgists are now engaged in research to understand the old processes and their implications for developing corrosion-resistant iron for specific applications like concrete reinforcement bars.Many healing systems from non-Western sources, including Indian medical systems, are now being revived. These complement modern medicine. Besides physical healing systems, such as Ayurveda, there is growing interest in Indian systems of mind-management, including forms of yoga and meditation. These have been incorporated in the West in the form of stress management or motivational training.Less than five per cent of the known classical Indian texts (in Sanskrit, Tamil, etc.) have ever been translated. What might be the insights and knowledge systems of our ancestors that lie hidden in these?An example of the works detailing the history of traditional science (including from China and even Native Americans) is the Springer Encyclopaedia of the History of Science, Technology, and Medicine in Non-Western CulturesSummary:India's scientific heritage, besides its philosophical and cultural legacy, needs to be properly understood. The aim is not inspired by chauvinism, but to understand the genius of Indian civilization better. This would overhaul the current assessment of India's potential, and give its people a better rooted place in history.To correct the portrayal of the History of Science, the History of Ideas, mainstream accounts of World History, anthropology and culture. This entails emphasizing to scholars and educators that Traditional Knowledge Systems should be included, especially India's achievements and contributions to world science that have been very significant but unappreciated.To include Traditional Knowledge Systems in economic planning, because they are eco-friendly, sustainable, labour rather than capital intensive, and more available to the masses. This should be done in parallel with the top down 'modern' scientific development using westernized 'globalization', as the two should co-exist and each should be used on the basis of its merits.It is, therefore, imperative that we study, preserve, and revive traditional knowledge systems. India's scientific heritage needs to be highlighted so as to replace Eurocentric historiography with an honest history of ideas. Especially for the Non resident Indians have an important role here. Every new immigrant group, be it in America or Europe has to define itself in the eyes of the public though a process of education about its history, culture, values and special strengthsIt is in everyone’s best interest that there should be a true globalization of the education system, in which all cultures’ contributions and merits are celebrated. This would build greater harmony, and would be consistent with the multicultural trajectory of USA. Just as Europe used Classical Greek thought to get out of their Dark Ages into Modernity, so also Indians could use their Classics to move forward. This would complement modern knowledge and not replace it.Indian Contributions to Science and Technology:The depth and breadth of Indian science and technology is staggering, and this section gives just a glimpse into the genius of India's scientists and engineers.Traditional Knowledge Systems:Modern Western technology has produced amazing achievements, but we must analyze the wider implications of such technologies and their notions of progress. These technologies often bring huge negative consequences that seem negligible in the short-term. We need to dispassionately investigate whether there are alternative technologies that offer more sustainable progress for all, rather than only the privileged.In search for such technologies, traditional knowledge or ‘local knowledge' provides a pointer. Traditional knowledge is the technical, social, organizational and cultural collective memory of human responses to the complexities of life, and is a part of the great human experiment of survival and development. Western criteria should not be the sole benchmark by which non-Western cultural knowledge is evaluated. While Western intellectual discourse has marginalized the term 'traditional' with the connotation of 'pre-modern' in the sense of 'primitive' or 'outdated', many of the traditional sciences and technologies were quite advanced by ‘modern' standards as well as better adapted to unique local conditions and needs than their later substitutes.These traditional folk and elite sciences are intertwined with their distinct ancient cultures and worldviews. Unfortunately, modernization has homogenized the categories, reducing diversity of worldviews in ways similar to the destruction of biodiversity. Using contrived hegemonic categories – such as science verses magic, technology verses superstitions, modern versus tradition – European colonizers systematically exterminated or undermined local traditional science, technology and crafts. Aside from intellectual arrogance, there was a profit motive to this – as evidenced by Britain's conquest of Indian textile and metallurgical know-how. Many anthropologists who have recently worked with so-called 'primitive' peoples have been surprised to learn of some of their highly evolved and sophisticated technologies. The term 'Traditional Knowledge System' was thus coined as a scientific system which has its own validity, as a supplement to 'modern' science.Hereafter some details on History of Indian Science and Technology are elaborated:Civil Engineering:From complex Harappan towns to Delhi's Qutub Minar, India's indigenous technologies were very sophisticated. They included the design and planning of water supply, traffic flow, natural air conditioning, complex stone work, and construction engineering.Most students learn about the ancient cities of the Middle East and China. How many have even a basic understanding of the world's oldest and most advanced civilization – the Harappan or Indus-Sarasvati Valley Civilization in India? The Indus-Sarasvati Civilization was the world's first to build planned towns with underground drainage, civil sanitation n, hydraulic engineering, and air-cooling architecture. While the other ancient civilizations of the world were small towns with one central complex, this civilization had the distinction of being spread across many towns, covering a region about half the size of Europe. Weights and linguistic symbols were standardized across this vast geography, for a period of over 1,000 years, from around 3,000 BCE to 1500 BCE. Oven-baked bricks were invented in India in approximately 4,000 BCE. Over 900 of the 1,500 known settlement sites discovered so far are in India.Since the Indus-Sarasvati script is yet to be decoded, it remains a mystery as to how these people could have achieved such high levels of sophistication and uniformity in a dispersed complex and with no visible signs of centralized power.For instance, all bricks in this civilization are of the ratio 1:2:4 regardless of their size, location or period of construction. There are many pioneering items of civil engineering, such as drainage systems for water (open and closed), irrigation systems, river dams, water storage tanks carved out of rock, moats, middle-class style homes with private bathrooms and drainage, and even a dockyard; there is evidence of stairs for multiple-storied buildings; many towns have separate citadels, upper and lower towns, and fortified sections; there are separate worker quarters near copper furnaces; granaries have ducts and platforms; and archeologists have found geometric compasses, linear scales made of ivory. Indians also pioneered many engineering tools for construction, surgery, warfare, etc. These included the hollow drill, the true saw, and the needle with the hole on its pointed end.Water Management:Given the importance of fresh water in India, it is no surprise that the technologies to manage water resources were highly advanced from Harappan times onwards. For example, in Gujarat, Chandragupta built the Sudarshan Lake in late 4th century BCE, and was later repaired in 150 BCE by his grandson. Bhopal's Raja Bhoj Lake, built in 1014-1053, is so massive that it shows up in satellite images. The Vijayanagar Empire built such a large lake in 14th– 15th century CE that it has more construction material than the Great Wall of China. What some historians call the “Persian Wheel” is actually pre-Mughal and indigenous to India.Scientists estimate there were 1.3 million man-made water lakes and ponds across India, some as large as 250 square miles. These are now being rediscovered using satellite imagery. These enabled rain water to be harvested and used for irrigation, drinking, etc. till the following year's rainfall.Textiles:Indian textiles have been legendary since ancient times. The Greeks and Romans extensively imported textiles from India. Roman archives record official complaints about massive cash drainage due to these imports from India.One of the earliest industries relocated from India to Britain was textiles and it became the first major success of the Industrial Revolution, with Britain replacing India as the world's leading textile exporter. What is suppressed in the discourse about India and Europe is the fact that the technology, designs and even raw cotton were initially imported from India while, in parallel, India's indigenous textile mills were outlawed by the British. India's textile manufacturers were de-licensed, even tortured in some cases, over-taxed and regulated, to 'civilize' them into virtual extinction. Textiles and steel were the mainstays of the British Industrial Revolution. Both had their origins in India. The Ahmedabad textile museum is a great resource for scholarly material.Iron and Steel:Iron is found in countries neighboring India, leading European scholars to assume that it came from outside India. Given the similarities between the Vedas and Avesta (a Zoroastrian text), some saw this as supporting the theory of diffusion of iron and Vedas into India from the outside. Refuting this, Vibha Tripathi finds that iron in India is much older. (See details in a subsequent chapter.) Cemeteries in present-day Baluchistan have iron objects. The earlier iron found in Middle Eastern archeological sites was essentially meteorite material sculptured as rock/stone carvings, and was not metallurgically processed at all. Since iron can be a by-product of copper technology, this could be its likely origin in India because copper was a well-known technology in many parts of ancient India. A smelting furnace dated 800 BCE is found in Naikund (Maharashtra), India. Recent discoveries reveal that iron was known in the Ganga valley in mid second millennium BCE. In the mid-first millennium BCE, the Indian wootz steel was very popular in Persian courts for making swords.Rust-free steel was an Indian invention, and remained an Indian skill for centuries. Delhi's famous iron pillar, dated 402 CE, is considered a metallurgical marvel and shows minimal signs of rust. The famous Damascus steel swords, now displayed in museums across Europe, were made from Indian steel imported by Europeans. The acclaimed Sheffield steel in UK was Indian crucible steel. The best brains of European science worked for decades to learn to reverse-engineer how Indians made crucible steel, and in this process, modern alloy design and physical metallurgy was developed in Europe. (For details see later chapters with book summaries.)Indian industry was dealt a death blow by the colonial masters who banned the production and manufacture of iron and steel at several places in India, fearing their use in making swords and other arms. In addition, they also ensured India would depend upon iron and steel imported from Europe.Zinc Metallurgy:Another important Indian contribution to metallurgy was in the isolation, distillation and use of zinc. From natural sources, zinc content in alloys such as brass can go no higher than 28 per cent. These primitive alloys with less than 28 per cent zinc were prevalent in many parts of the world before India. However, to increase the zinc content beyond this threshold, one must first separate the zinc into 100 per cent pure form and then mix the pure zinc back into an alloy. A major breakthrough in the history of metallurgy was India's discovery of zinc distillation whereby the metal was vaporized and then condensed back into pure metal.Brass in Taxashila has been dated from third century BCE to fifth century CE. A vase from Taxashila is of particular interest because of its 34.34 per cent zinc content and has been dated to the third century BCE (Marshall 1951: 567-568). Recently two brass bangles belonging to the Kushana period have been discovered from Senuwar (Uttar Pradesh, India). They are also made of metallic zinc as they have 35 per cent zinc content (Singh 2004: 594). Experts are unsure if this zinc was made by distillation process.There is evidence of zinc ore mining at Zawar in Rajasthan from the fifth century BCE, but unfortunately there is lack of evidence of regular production of metallic zinc until the eighth century CE. The earliest confirmed evidence of zinc smelting by distillation is dated back to 840 +110 from Zawar (Craddock et al. 1985, 1989). This is the earliest date for zinc smelting and production of metallic zinc by distillation process anywhere in the world.Europeans learnt it for the first time in 1743, when know-how was transferred from India. Until then, India had been exporting pure zinc for centuries on an industrial scale. At archeological sites in Rajasthan, retorts used for the distillation are found in very large numbers even today.Once zinc had become separated into a pure metal, alloys could be made with the required zinc component to provide the required properties. For instance, strength and durability increase with higher zinc component. Also, copper alloys look like gold when the zinc component is higher than 28 per cent. Most early brass objects found in other countries had less than 10 per cent zinc component, and, therefore, these were not based on zinc distillation technology.Alloys that exceed 10 per cent zinc are found earliest in Taxashila in the fourth century BCE. However, while Taxashila was distilling and manufacturing zinc on a small scale, it was in Zawar, Rajasthan, where this first became industrialized on a large scale. Zinc mines have been found in Dariba (11th century BCE), Agucha (sixth century BCE) and Zawar (fifth century BCE). These mines have pots and other manufacturing tools of these dates, but the mining could be even older. (See further details in later chapters.)Three important items are now proven about the history of zinc metallurgy: (i) zinc distillation and metallurgical usage was pioneered in India; (ii) industrial scale production was pioneered in Rajasthan; (iii) England transferred the technology of zinc from India in 1736. British metallurgy documents do not mention zinc at all prior to this transfer.Shipping and Shipbuilding:Shipbuilding was one of India's major export industries until the British dismantled it and formally banned it. Medieval Arab sailors purchased their boats in India. The Portuguese also continued to get their boats from India and not Europe. Some of the world's largest and most sophisticated ships were built in India and China.The compass and other navigation tools were already in use in the Indian Ocean long before Europe. (“Nav” is the Sanskrit word for boat, and is the root word in “navigation” and “navy”.) Using their expertise in the science of seafaring, Indians participated in the earliest-known ocean-based trading system.Few people know that an Indian naval pilot, named Kanha, was hired by Vasco da Gama to captain his ships and take him to India. Some of Europe's acclaimed “discoveries” in navigation were in fact appropriations of a well-established thriving trade system in the Indian Ocean. Contrary to European portrayals that Indians knew only coastal navigation, deep-sea shipping had existed in India as Indian ships had been sailing to islands such as the Andamans, Lakshdweep and Maldives around 2,000 years ago. Kautilya describes the times that are good and bad for seafaring. There is also extensive archival material on the Indian Ocean trade in Greek, Roman, and Southeast Asian sources.Forest Management:Many interesting findings have recently come out about the way forests and trees were managed by each village and how a careful method was applied to harvest medicines, firewood and building material in accordance with natural renewal rates. There is now a database being built of 'sacred groves' across India. Once again, it's a story of an economic asset falling into disuse and abuse because of the dismantling of local governance and disrespect for traditional systems.Furthermore, when scholars try to explain India's current ecological disasters, they seldom mention the large-scale logging of Indian timber by the British in order to fund the two world wars and various other industrial programs of the empire.Farming Techniques:Indian farmers developed non-chemical, eco-friendly pesticides and fertilizers that have modern applications. These traditional pesticides have been recently revived in India with excellent results, replacing Union Carbide's products in certain markets. Crop rotation and soil technology that has been passed down for thousands of years are traditional practices which India pioneered.Historically, India's agricultural production was large and sustained a huge population compared to other parts of the world. Surpluses were stored for use in a drought year. But the British turned this industry into a cash cow, exporting very large amounts of grain even during food shortages. This caused tens of millions of Indians to die of starvation in the 19th century.Traditional Medicine:Much re-legitimizing of traditional Indian medicine has already started, thanks in part to many Western labs and scientists. Many multinationals no longer denigrate traditional medicine and have in fact been trying to secure patents on Indian medicine without acknowledging the source. Traditional medicine is now a well-known and respected field.Mathematics:Prof. C.K Raju, a renowned scholar, has researched the “clash of epistemologies” that occurred in European ideas about numbers. When Europeans started to import Indian ideas about mathematics, what had been natural to Indian thinkers for a long time was very hard for Europeans to accept. He divides this into three periods:The first math war in Europe was from 10th to 16th centuries, during which time it took Europe 500 years to accept the zero, because the Church considered it to be heresy.The second math war was over the Indian concept of indivisibles, which led to the theory of real numbers and infinitesimals, paving the way for the development of calculus. This war lasted three centuries, from the 17th to 19th centuries.The third math war is now under way and is between computational math (Indian algorithmic approach) and formal math (Western approach).Additionally, Indians developed many important concepts including the base-ten decimal system, now in global use, and crucial trigonometry and algebra formulae. They made several astronomical discoveries. Diverse schools of logic and philosophy proliferated.Mathematical thought was intertwined with linguistics. India's Panini is acknowledged as the founder of linguistics, and his Sanskrit grammar is still the most complete and sophisticated of any language in the world.“Folk” Sciences:Besides the above examples of Indian contributions to the origins of the so-called “Western” science, there is another category of traditional knowledge called non-literate folk science. Western science as a whole has condemned and ignored anything that it did not either appropriate or develop, by branding it as magic and superstition. However, in countries such as India, which boast of cultural continuity, ancient traditions survive with a rich legacy of folk science.In North America and Australia, where original populations have been largely decimated, such continuity of folk tradition was disrupted. In Western nations with large colonies in the Old and New Worlds, such knowledge systems were looked down upon once they had been successfully plundered. The process of contrasting Western science with folk knowledge systems has led to the imposition of contrived hegemonic categories.The distinction between elite and folk science was non-existent in ancient times. India's advanced metallurgy and civil engineering was researched and practiced by artisan guilds. Western science seldom realized that non-literate folk science preserves the wisdom gained through millennia of experience and direct observation, and has been transmitted by word of mouth.For instance, modern scientists have humbly admitted that the ecological management practiced today by the tribes of India's Northeast is far superior to anything they could teach them. A good example is the use of alder (Alnus nepalensis), which has been cultivated in the jhum (shifting cultivation) fields by the Khonoma farmers in Nagaland for centuries. It has multiple usages for the farmers, since it is a nitrogen-fixing tree and helps to retain the soil fertility. Its leaves are used as fodder and fertilizer, and it is also utilized as timber. One could cite numerous such examples.The vast majority of modern medicines patented by Western pharmaceutical firms are based on tropical plants. The most common method to select candidates for detailed testing has been for Western firms to scout tropical societies, seek out established “folk” remedies and subject these to testing by “Western science”. In many cases, patents owned by multinationals are largely for isolating the active ingredients in a lab and going through rigorous protocols of testing and patent filing. While this is an important and expensive task that deserves credit, these are seldom truly independent discoveries from scratch. Never has the society that has discovered them through centuries of empirical trial and error received any recognition, much less any share of royalty.Colin Scott writes: "With the upsurge of multidisciplinary interest in 'traditional ecological knowledge', models explicitly held by indigenous people in areas as diverse as forestry, fisheries, and physical geography are being paid increasing attention by Western scientists, who have in some cases established extremely productive long-term dialogues with local experts. The idea that local experts are often better informed than their Western peers is at last receiving significant acknowledgment beyond the boundaries of anthropology."Myths and legends sometimes represent the attempts of our ancestors to explain the scientific observations they made about the world around them and transmitted these to the future. They chose different models to interpret the observations, but the observations were empirical. Theorizing the possible role of myths, Scott writes: "The complementarity of the literal and the figurative helps us to realize that the distinction between myth and science is not structural, but procedural ... Myths in a broader, paradigmatic sense are condensed expressions of root metaphors that reflect the genius of particular knowledge traditions ... Numerous studies have found that the "anthropomorphic" paradigms of egalitarian hunters and horticulturalists not only generate practical knowledge consistent with the insights of scientific ecology, but simultaneously cultivate an ethic of environmental responsibility that for western societies has proven elusive."Despite these acknowledgments, in too many cases Western scholars reduce India's experts to “native informants” who are seen located below the glass ceiling: the pandit as native informant to the Western Sanskritist; the poor woman in Rajasthan as native informant to the Western feminist seeking to cure her of her native tradition; the herbal farmer as native informant to the Western pharmaceutical firm appropriating medicines for patents. Given their poverty in modern times, these 'native informants' dish out whatever the Western scholar expects to hear in order to fit his/her thesis, because in return they receive rewards. Rarely have Western scholars acknowledged India's knowledge bearers as equal partners. The obsession to make 'original' discoveries and to put one's name on publications has exacerbated the tendency to appropriate with one hand, while denigrating the source with other hand. This deserves to be called 'academic arson'.Relationship with Inner Sciences:India's inner sciences of mind and consciousness are simultaneously (a) being appropriated by the West and (b) being depicted as anti-progressive and irrational. In fact, inner and outer realms of inquiry are often viewed as opposites that can, at best, be balanced but not unified. This falsely assumes that the inner sciences make a person and society less productive, creative, and competitive in the outer realm. However, contradicting this, India's inner sciences and outer development coexisted in a mutually symbiotic relationship.A strong inner science will definitely strengthen the outer science since it is the inner world which provides the inspiration, creativity, and knowledge that is necessary in the development of a sound outer science. A strong outer science allows the freedom for the exploration of the inner science. Without the use of technology of some form, man will be forced to dwell in his lower nature to satisfy his basic needs of survival.The divorce of ‘religion' and science is a strictly Western construct due to the dogmatic and rigid nature of the Abrahamic religions. History-centric religions (such as Judaism, Christianity, and Islam) are often not compatible with the human tendency towards freedom of thought, intellectual originality, and non-conformity of thought which are necessary in scientific innovation. The tradition of spiritual experimentation in India, however, is compatible with the material and intellectual experimentation required by science.Many ancient Hindu-Buddhist inner science discoveries are being misappropriated and/or plagiarized:‘Lucid Dreaming’ is the western name for Indo-Tibetan nidra yoga, and Stanford’s Stephen LaBerge is nowadays the acknowledged discoverer.‘Mindfulness Meditation’ is Jon-Kabat Zinn’s repackaged and trademarked vipassna.Herb Benson repackaged TM into his ‘Relaxation Response’ and now runs a multimillion dollar business based at Harvard, claiming these as his discoveries. Numerous spin-offs in mainstream stress management and management consulting theories came from this source.Rupert Sheldrake recently ‘came out’ in an interview acknowledging that his famous theory known as ‘Morphogenic Resonance’ was developed while researching in India’s ashrams.Ken Wilber started out very explicitly as an interpreter of Sri Aurobindo’s philosophy for the benefit of psychologists, but now places himself as the discoverer on a higher pedestal.Esalen Institute appropriated J. Krishnamurti and numerous other Indic thinkers into what its contemporary followers regard as it own ‘New Worldview’.Thomas Berry, Father Keating (in the footsteps of Bede Griffiths), and others have constructed the New Liberal Christianity, using Indic appropriations. Jewish scholars have likewise constructed the ‘non-dualistic Kabala’ based on Vedanta. While these pioneers recognize and admit the source, there followers are often ignorant and see these innovations as emerging entirely from Judeo-Christianity.References:Indic Contributions to World ScienceHistory of Indian Science And TechnologyIndic Mandala
