  • [pib] Indian Digital Heritage (IDH) Initiative

     

    The Union Ministry of Culture and Tourism launched a month-long special exhibition titled Indian Heritage in Digital Space. This special exhibition showcases the adaptation and infusion of technologies being developed under the Indian Digital Heritage (IDH) initiative.

    Indian Digital Heritage (IDH)

    • This initiative is undertaken by the Department of Science and Technology (DST) in the cultural heritage domain of the country.
    • The exhibition demonstrates the outcome of two flagship projects viz., A digital mini-spectacle to showcase the glory of Hampi and Augmented Reality based interactions with physical models of monuments.
    • The goals of these projects are to create digital installations using 3D laser scan data, AR, holographic projections and 3D fabrication,to provide interactive and immersive experiences showcasing the glory of Hampi and five Indian monuments namely Kashi Vishwanath Temple, Varanasi; TajMahal, Agra; Sun Temple, Konark; Ramachandra Temple, Hampi ; and RaniKiVav, Patan .
    • These projections are driven by cutting-edge technologies such as 3D fabrication, Artificial Intelligence, Augmented, Virtual and Mixed Reality, Holographic Projections and Projection Mapping etc.

    ViRaasat

    A special installation named ‘ViRaasat’, consisting of a scaled-down 3D printed replica shall provide a mixed reality experience to visitors for selected monuments, using laser-scanning, 3D modelling and rendering, 3D printing, computer vision and spatial AR.

  • Classical languages in India

    Recently in a Marathi literary festival, a resolution was passed demanding its declaration as a ‘Classical’ language.

    ‘Classical’ languages in India

    Currently, six languages enjoy the ‘Classical’ status: Tamil (declared in 2004), Sanskrit (2005), Kannada (2008), Telugu (2008), Malayalam (2013), and Odia (2014).

    How are they classified?

    According to information provided by the Ministry of Culture in the Rajya Sabha in February 2014, the guidelines for declaring a language as ‘Classical’ are:

    • High antiquity of its early texts/recorded history over a period of 1500-2000 years;
    • A body of ancient literature/texts, which is considered a valuable heritage by generations of speakers;
    • The literary tradition be original and not borrowed from another speech community;
    • The classical language and literature being distinct from modern, there may also be a discontinuity between the classical language and its later forms or its offshoots.”

    How are the Classical languages promoted?

    The HRD Ministry noted the benefits it provides once a language is notified as a Classical language:

    • Two major annual international awards for scholars of eminence in classical Indian languages
    • A Centre of Excellence for studies in Classical Languages is set up
    • The University Grants Commission is requested to create, to start with at least in the Central Universities, a certain number of Professional Chairs for the Classical Languages so declared.

  • Six degrees of Endangerment of a Language

    Recently, The NY Times reported that the “near-extinct” Nepalese language Seke has just 700 speakers around the world. As per the Endangered Languages Project (ELP), there are roughly 201 endangered languages in India and about 70 in Nepal.

    The last year, 2019, was the International Year of Indigenous Languages, mandated by the UN.

    Nepal’s Seke language

    • According to the Endangered Language Alliance (ELA), Seke is one of the over 100 indigenous languages of Nepal.
    • The dialects from these villages differ substantially and are believed to have varying degrees of mutual intelligibility.
    • In recent years, Seke has been retreating in the face of Nepali, which is Nepal’s official language and is considered to be crucial for getting educational and employment opportunities outside villages.

    Degrees of endangerment

    UNESCO has six degrees of endangerment. These are:

    1. Safe, which are the languages spoken by all generations and their intergenerational transmission is uninterrupted;
    2. Vulnerable languages, which are spoken by most children but may be restricted to certain domains;
    3. Definitely endangered languages, which are no longer being learnt by children as their mother tongue.
    4. Severely endangered are languages spoken by grandparents and older generations, and while the parent generation may understand it, they may not speak it with the children or among themselves.
    5. Critically endangered languages are those of which the youngest speakers are the grandparents or older family members who may speak the language partially or infrequently and lastly,
    6. Extinct languages, of which no speakers are left.

  • Virtual human’ NEON

    NEONs are being called the world’s first artificial humans. They look and behave like real humans, and could develop memories and emotions — though from behind a 4K display.

    NEON

    • Star Labs is headed by India-born scientist Pranav Mistry who underlines that what was showcased at CES was the product of just four months’ work.
    • The company says NEONs are computationally created virtual humans — the word derives from NEO (new) + humaN.
    • For now, the virtual humans can show emotions when manually controlled by their creators.
    • But the idea is for NEONs to become intelligent enough to be fully autonomous, showing emotions, learning skills, creating memories, and being intelligent on their own.
    • Star Labs thinks they can be “friends, collaborators, and companions”, but all that is a few years away.

    How does it work?

    There are two core technologies behind his virtual humans.

    • First, there is the proprietary CORE R3 technology that drives the “reality, real time and responsiveness” behind NEONs.
    • It is the front-end reality engine that is able to give you that real expression.
    • The company claims CORE R3 “leapfrogs in the domains of Behavioral Neural Networks, Evolutionary Generative Intelligence and Computational Reality”, and is “extensively trained” on how humans look, behave and interact.
    • But in the end, it is like a rendition engine, converting the mathematical models to look like actual humans.
    • The next stage will be SPECTRA, which will complement CORE R3 with the “spectrum of intelligence, learning, emotions and memory”.
    • But SPECTRA is still in development, and is not expected before NEONWORLD 2020 later this year.

    How could NEONs be used?

    • NEONs are the interface for technologies and services.
    • They could answer queries at a bank, welcome you at a restaurant, or read out the breaking news on television at an unearthly hour.
    • This form of virtual assistance would be more effective, for example, while teaching languages, as NEONs will be capable of understanding and sympathizing.

    How are they different from Virtual Assistants?

    • Virtual Assistants now learn from all the data they are plugged into. NEONs will be limited to what they know and learn.
    • Their leaning could potentially be limited to the person they are catering to, and maybe her friends — but not the entire Internet.
    • They will not be an interface for you to request a song, rather they will be a friend to speak to and share experiences with.
    • Currently, its developer doesn’t want NEONs to have collective memory, or to share data among themselves.

  • Artemis Mission

    NASA wants to send the first woman and the next man to the Moon by the year 2024, which it plans on doing through the Artemis lunar exploration program. An Indian American astronaut named Raja Chari is set to accompany the crew in this mission.

    Artemis Mission

    • In 2011, NASA began the ARTEMIS (Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon’s Interaction with the Sun) mission using a pair of repurposed spacecraft and in 2012 the Gravity Recovery and Interior Laboratory (GRAIL) spacecraft studied the Moon’s gravity.
    • For the program, NASA’s new rocket called the Space Launch System (SLS) will send astronauts aboard the Orion spacecraft a quarter of a million miles away from Earth to the lunar orbit.
    • The astronauts going for the Artemis program will wear newly designed spacesuits, called Exploration Extravehicular Mobility Unit, or xEMU.
    • These spacesuits feature advanced mobility and communications and interchangeable parts that can be configured for spacewalks in microgravity or on a planetary surface.

  • Person in news: Swami Vivekananda

    January 12 is the birth anniversary of Swami Vivekananda, the famous spiritual leader and intellectual from the late 19th century. In his honour, the government of India in 1984 declared his birthday as National Youth Day.

    Swami Vivekananda early life

    • Vivekananda was born in Kolkata on January 12, 1863, as Narendra Nath Datta.
    • From an early age, he nurtured an interest in Western philosophy, history, and theology, and went on to meet the religious leader Ramakrishna Paramhansa, who later became his Guru.
    • He remained devoted to Ramakrishna until the latter’s death in 1886.
    • In 1893, he took the name ‘Vivekananda’ after Maharaja Ajit Singh of the Khetri State requested him to do so, changing from ‘Sachidananda’ that he used before.
    • After Ramakrishna’s death, Vivekananda toured across India, and set after educating the masses about ways to improve their economic condition as well as imparting spiritual knowledge.

    The Chicago address

    • Vivekananda is especially remembered around the world for his speech at the Parliament of the World’s Religions in Chicago in 1893.
    • The speech covered topics including universal acceptance, tolerance and religion, and got him a standing ovation.
    • He began delivering lectures at various places in the US and UK, and became popular as the ‘messenger of Indian wisdom to the Western world’.

    Return to India

    • After coming back to India, he formed the Ramakrishna Mission in 1897 “to set in motion a machinery which will bring noblest ideas to the doorstep of even the poorest and the meanest.”
    • In 1899, he established the Belur Math, which became his permanent abode.

    His legacy

    • Through his speeches and lectures, Vivekananda worked to disseminate his religious thought.
    • He preached ‘neo-Vedanta’, an interpretation of Hinduism through a Western lens, and believed in combining spirituality with material progress.
    • ‘Raja Yoga’, ‘Jnana Yoga’, ‘Karma Yoga’ are some of the books he wrote.
    • An important religious reformer in India, Swami Vivekananda is known to have introduced the Hindu philosophies of Yoga and Vedanta to the West.
    • Subhas Chandra Bose had called Vivekananda the “maker of modern India.”

  • Coronavirus

    A new virus has been identified by Chinese researchers which is responsible for a new pneumonia-like illness.

    Coronavirus

    • Coronaviruses are a specific family of viruses, with some of them causing less-severe damage, such as the common cold, and others causing respiratory and intestinal diseases.
    • A coronavirus has many “regularly arranged” protrusions on its surface, because of which the entire virus particle looks like an emperor’s crown, hence the name “coronavirus”.
    • Apart from human beings, coronaviruses can affect mammals including pigs, cattle, cats, dogs, martens, camels, hedgehogs and some birds.
    • So far, there are four known disease-causing coronaviruses, among which the best known are the SARS coronavirus and the Middle East Respiratory Syndrome (MERS) coronavirus, both of which can cause severe respiratory diseases.

  • [op-ed of the day] The age of ubiquitous drones and the challenges overhead

    Context

    Increasing the use of drones in warfare and other areas has brought into focus the potential the use of drones hold and the other issues related to its misuse.

    Recent events featuring drones

    • A drone was used by the U.S. to fire the missile at Qassem Soleimani to assassinate him.
    • A few days before that, less-lethal drones monitored crowds of student protesters rocking India.

    A potential area of use of drones

    • Military and Policing: Drones are largely used for military or policing purposes, but they also have other uses.
    • Recreation and Sports: They are used for recreation and sports. The Chinese company DJI dominates this space.
    • Logistics: Logistics is another use, with Amazon developing last-mile drone delivery.
    • At scale, this delivery model can save money, energy and time.
    • Domino’s extended this logic to deliver its first pizza by drone in New Zealand and is experimenting with scaling this model up in many markets.
    • Botswana has had some successful trials where drones have delivered blood and life-saving drugs to villages out in the wilderness.
    • Agriculture: A startup called Terraview uses drones with advanced image processing, machine learning, artificial intelligence, and augmented reality to increase the productivity of vineyards.
    • A drone can be used to measure the amount of grain that’s piled up after harvest.
    • Mining Output: Tata Steel has used drones quite effectively to measure mining output.
    • Access the inaccessible places: Drones can go where people cannot.
    • So, inspection and repair at remote wind farms on an island, or pipelines in the remote tundra, or equipment in a rainforest can be done more cheaply and precisely.
    • Drone surveillance is now widely used by the insurance industry in the aftermath of floods or pest inspections.
    • They can provide organizations a 360-degree view of the status of any construction project and its assets.
    • Explosive detection and defusing: In many places, it is just safer to send a drone, such as while using explosives in deep mines or defusing suspected bombs.
    • Wildlife protection and survey: drones are used to survey wildlife and detect poaching in the jungles of Africa.

    Drones as commodity

    • Drones will soon become a hardware commodity, much like personal computers.
    • It will be the software loaded on it that will be the real force-multiplier.
    • Industry 4.0 revolution: Business like “drones-as-a-service” will emerge, dramatically reducing the time taken for tasks and serving as a vital tool in the Industry 4.0 revolution.

    A potent tool for Swarm-attack by military

    • Perhaps the most fascinating developments will occur where drones originated, in
    • Drones will mutate into swarms, where multiple, intelligent, small drones act as one vast network, much like a swarm of birds or locusts.
    • Advanced militaries have drone swarms under trial that could revolutionize future conflicts.
    • These swarms could overwhelm enemy sensors with sheer numbers and precisely target enemy soldiers and assets using data fed into them.
    • They will be difficult to shoot down as there will be hundreds of small flying objects rather than one big ballistic missile.
    • The swarm will use real-time ground data to organize itself and operate in concert to achieve its goal.

    Issues with drones

    • It will be us humans who will decide whether we use drones for beneficial or malevolent ends.
    • National Security Issues: Drones have demonstrated the potentials for their threat to the security of a country. Drones are operated remotely and can strike where it want it to strike. Raising serious security issues.
    • Terrorism: Drones have been used by various terrorist organisations like ISIS in Syria and Iraq to hit their targets.
    • Aviation safety: Drones flying too close to commercial aircraft has called for regulations.
    • Privacy: Drones have been used by the paparazzi to take the images of individuals breaching their privacy.

    Conclusion

    Drones can indeed be a fantastic tool for good projects, from helping save the planet to identifying and nabbing criminals, and preventing the loss of human life. However, for that, we will have to change the DNA that they were born with, as lethal weapons of war. Otherwise, they will remain anonymous killers, wreaking death and destruction as they hover innocuously above.
