WEAVING LEGACY, EMPOWERING ARTISANS

Indian Handloom 

India’s handloom sector is a living testament to the nation’s rich cultural heritage. Rooted in tradition, the art of handloom weaving has been passed down through generations, embodying the diverse cultural ethos of various regions. From the intricate Banarasi silks of Varanasi to the vibrant Phulkari from Punjab, Indian handlooms represent a confluence of history, artistry, and sustainability. This heritage not only showcases India’s craftsmanship but also provides livelihoods to over 35 lakh artisans.

10th National Handloom Day: A Tribute to Weavers

The 7th of August holds a special place in India’s history, marking the beginning of the Swadeshi Movement in 1905. This movement, which encouraged the use of indigenous products, played a crucial role in promoting the handloom industry. In recognition of this legacy, the Government of India, in 2015, declared August 7th as National Handloom Day. This day is dedicated to honouring the handloom weaving community and highlighting their contribution to the socioeconomic fabric of the nation. National Handloom Day, resolves to protect and promote our handloom heritage and to make it stronger than ever.

Initiatives Empowering Weavers

Prime Minister Narendra Modi is making every effort to promote handloom and support the weavers who uphold this rich tradition. Under his 5F Vision—Farm to Fibre to Fabric to Fashion to Foreign—the handloom sector is undergoing a remarkable transformation. Initiatives such as the Design Resource Centres are providing weavers, manufacturers, and designers with access to extensive design repositories, fostering innovation and driving excellence in the craft. Moreover, handloom villages located in popular tourist destinations like Kanihama in Jammu & Kashmir and Sharan in Himachal Pradesh are creating new opportunities for tourism and handloom sales, allowing visitors to take home a piece of India’s vibrant weaving tradition.

THE LANGUAGE OF NUMBERS

Sanskrit 

Sanskrit, the ancient language of India, is revered not only for its literary and philosophical richness but also for its profound influence on mathematics. The term ‘ganita,’ which means mathematics, originates from the Sanskrit root ‘gana,’ signifying ‘to count’ or ‘to enumerate.’ This connection underscores the deep relationship between Sanskrit and the development of mathematical thought in India.

Mathematical Foundations in Vedic Period: The seeds of mathematical inquiry were sown as early as the Vedic period. The Vedas, foundational scriptures of Indian knowledge, contain references to numbers, arithmetic progressions, and geometry. The intricate designs of Vedic altars, which required precise mathematical calculations, are evidence of this early engagement with mathematical concepts.

Pioneering Mathematicians: Indian mathematicians such as Aryabhata and Brahmagupta later elevated these early concepts to unprecedented heights. Aryabhata’s Aryabhatiya is a landmark work that covers arithmetic, algebra, geometry, and trigonometry. Brahmagupta’s Brahma-sphutasiddhanta expanded on these ideas, introducing quadratic equations and the concept of zero. 

Interplay of Language and Logic in Sanskrit Mathematics: The precision and conciseness of Sanskrit make it an ideal language for expressing complex mathematical ideas. The structure of Sanskrit grammar, with its patterns and symmetries, mirrors the underlying principles of mathematics. This linguistic framework enabled Indian scholars to articulate sophisticated mathematical concepts with clarity and elegance.

India’s Mathematical Contributions: India’s contributions to global mathematics are unparalleled, particularly the concept of zero, known as ‘shunya’ in Sanskrit, meaning void. This numeral revolutionized mathematics and introduced the concept of infinity. India also pioneered the decimal system, algebra, algorithms, square and cube roots, centuries before these ideas reached the rest of the world.

As we seek to revitalize Sanskrit today, it is crucial to recognize its invaluable role in the history of mathematics. By studying ancient Sanskrit texts, we not only honor the intellectual brilliance of our ancestors but also gain new insights into contemporary mathematical challenges. The deep connection between Sanskrit and mathematics offers a unique perspective on the evolution of human knowledge and innovation.

A SPOOKY CELEBRATION

Halloween

Halloween is a fun and spooky holiday celebrated on the night of October 31st. It’s a time when children and adults dress up in costumes, go trick-or-treating, and have lots of fun with eerie decorations. But do you know where Halloween comes from and why we celebrate it? Let’s dive into the world of Halloween and find out!

The Origins of Halloween: 

Halloween has a fascinating history that dates back over 2,000 years. Its roots can be traced to the ancient Celtic festival of Samhain, which marked the end of the harvest season and the beginning of winter. The Celts believed that on the night of October 31st, the boundary between the living and the dead became blurred. They would light bonfires and wear costumes to ward off evil spirits.

Trick-or-Treating:
One of the most exciting parts of Halloween for kids is trick-or-treating. Children dress up in costumes and visit houses in their neighbourhood, knocking on doors and shouting, “Trick or Treat!” People give them sweets and treats to prevent any tricks from being played on them. It’s all in good fun, and kids often collect a big bag of candy on Halloween night.

Spooky Decorations:
Halloween wouldn’t be the same without creepy decorations. Houses and gardens are adorned with carved pumpkins, also known as Jack-o’-Lanterns. These are pumpkins with scary faces lit up from the inside by a candle or a light. They are said to ward off evil spirits and add a spooky atmosphere to the celebration.

Dressing Up in Costumes:
Another exciting aspect of Halloween is choosing and wearing costumes. Children and adults love to transform themselves into spooky or funny characters. You can be anything you like, from a ghost to a superhero or even your favourite movie character. It’s a chance to let your imagination run wild!

Haunted Houses and Ghost Stories:
You might hear spooky ghost stories and tales of haunted places as Halloween approaches. Many people enjoy visiting haunted houses for a good scare. Some even believe that on Halloween, the spirits of the dead return to visit their old homes.

Halloween Around the World:
While Halloween is most popular in the United States, it’s celebrated in various forms in many countries. In India, for example, there are similar traditions during the days of the dead, and people light lamps and candles to honour their ancestors.

In Conclusion:

Halloween is a spooktacular holiday filled with fun and excitement. It has ancient origins, and today, it’s a time for children and adults to dress up in costumes, go trick-or-treating, and enjoy spooky decorations. Whether you believe in ghosts or enjoy the sweet treats, Halloween is a time to celebrate with friends and family.

VR

Virtual Reality 

Virtual Reality is an exciting technology that allows individuals to explore new environments, play games and learn in a completely immersive manner. It offers an interactive and educational experience that is both enjoyable and engaging. 

In 1968, Ivan Sutherland and his student, Bob Sproull, created first AR/VR mounted display connected to a computer, also known as the Ultimate Display. 

What is Virtual Reality?

Virtual Reality (VR) is computer-generated 3D environment that enables users to explore and interact with scenes and objects that appear to be real. Software is used to produce games, sounds and other sensations that create the illusion that the person is physically present in that environment. 

How does VR work?

VR headsets are wearable devices that track sensory information. When wearing a VR handset, your natural field of view is replaced with a computer-generated one. The headset projects a 360-degree digital environment that can be explored and navigated. Various electronic components such as display screens, 3D graphics and sound cards and process accelerator cards, enhance the content produced using cameras, motion sensors, infrared LEDs and speakers. The future of virtual reality is moving towards multisensory experiences, aiming for greater realism to enhance user immersion. 

Types of Virtual Reality 

● Non-immersive VR: Non-immersive interaction in the virtual environment is indirect, users do not experience the sensation of being physically present. The user remains aware of their physical surroundings while simultaneously accessing a 3D simulated environment through a computer screen. Control over the digital environment is achieved using devices like a keyboard, mouse, joystick and other peripherals. Examples of non-immersive VR include video games or websites that enable users to design room decor. 

● Semi-immersive VR: Interaction in the semi-immersive virtual environment is partial. Users feel as if they are in a different reality when focused on the digital image, yet remain connected to their physical surroundings. This set up involves a large concave screen, a projection system, a monitor and glasses or handsets with high-end computer graphics. An example of semi-immersive virtual reality is a flight simulator used by airlines and militaries to train pilots. 

● Fully-immersive VR: Fully-immersive VR completely envelopes the user in a simulated 3D world. This type of VR incorporates sight, sound and sometimes touch. Users wear specialised equipment such as helmets, goggles or glasses, a head-mounted display (HMD) and gloves, effectively disconnecting them from the physical world. Although fully-immersive VR technology is still in its early stages, it has already made significant advancements in the gaming industry. 

Applications of Virtual Reality 

● Training: VR provides an active experience during training, offering more than just passive information absorption. It proves particularly beneficial in areas requiring high-risk or highly specialised skills, such as training firefighters, police officers, soldiers and surgeons. 

● Education: Students can grasp complex concepts, subjects or theories better. VR enhances memory retention, recall, hand-eye coordination and spatial awareness. For instance, a history teacher might use VR to illustrate life in ancient Greece or China. 

● Entertainment: VR has had a profound impact on the gaming industry, offering gamers a chance to navigate challenges in a virtual world alongside virtual characters. The film and television sectors are also exploring ways to provide viewers with immersive experiences. Virtual tourism enables people to virtually experience distant locations, going beyond mere pictures. 

● Healthcare and Medicine: VR enables doctors to practise various surgeries in a virtual space using haptic controllers with VR software guiding surgeons through necessary steps. VR can also be used to explain surgical procedures to patients. 

● Real Estate and Interiors: VR allows home buyers to virtually tour properties, architects to showcase detailed 3D plans and homeowners to preview remodelled homes. This offers an accurate feel for scale, depth and spatial awareness. 

● Engineering: VR engineering involves using 3D modelling tools and visualisation techniques during the design phase. Engineers can view projects in 3D, gaining better understanding and identifying potential risks before implementation. This also provides a safe environment for design adjustments. 

A BIRD-WATCHER'S PARADISE

Keoladeo National Park

India is privileged to have a national park that is acknowledged as one of the world’s most important bird breeding and feeding grounds. This is the Keoladeo National Park, formerly known as the Bharatpur Bird Sanctuary, where hundreds of exotic migratory birds from faraway Siberia, Central Asia, and Africa arrive to spend the winter.

The park, spanning an area of 29 sq km in the Bharatpur district of Rajasthan, about 55 km west of Agra and 175 km southwest of Delhi, occupies a strategic location in the middle of the Central Asian migratory flyway and also has abundant water. These two factors have caused it to become an internationally important region where birds migrating down the Central Asian flyway congregate before dispersing to other regions.

This park is the only known wintering site of the central population of the critically endangered Siberian crane. It also serves as a wintering area for other globally threatened species such as the greaterspotted eagle and imperial eagle.

Originally a private hunting ground of the Maharaja of Bharatpur, the site was notified as a bird sanctuary in 1956. In 1982, it was elevated to the status of a national park and renamed after the Keoladeo temple, an ancient temple dedicated to Lord Shiva that stands at the centre of the site. The same year, it was designated as a Ramsar site(wetland of international importance under the Ramsar Convention). 

In 1985, the Keoladeo NationalPark was listed as a World Heritage Site by UNESCO.

Today, it not only is a haven for birdwatchers and nature enthusiasts, but also serves as an important research and conservation centre for ornithologists and ecologists. The park has an interesting history. The area where it stands was originally a natural depression that was inundated when Maharaja Suraj Mal, the ruler of the then princely state of Bharatpur, constructed a bund at the confluence of the Gambhir and Banganga rivers between 1726 and 1763 to prevent floods in his capital. This resulted in the development of an area comprising lakes and ponds, woodlands, wetlands and marshes with a lot of aquatic vegetation that attracted numerous migratory birds. 

It was subsequently designated as the ruler’s private duck-hunting reserve for the use of the royal family and their colonial visitors, and was later formally inaugurated in 1901 by Lord Curzon, the then Viceroy of India. As per an inscription found on a pillar near the temple, the then Viceroy, Lord Linlithgow, set a record on November 12, 1938 by shooting 4,273 birds here in a single day. 

Even after the site was turned over to the Forestry department, the Maharaja continued to retain shooting rights until 1972, when the Wildlife (Protection) Act was passed, prohibiting hunting.

With a wide diversity of habitats ranging from marshes, woodlands, scrublands, and grasslands to denuded saline patches, the park supports an amazing variety of plant and animal species. One third of the habitat is wetland with varying types of micro habitats having trees, mounds, dykes, and open water with or without submerged or emergent plants. The remaining terrain consists of tropical dry deciduous forest, scrub woodland, and dry grassland. More than 370 species of birds have been recorded in the park, the most common being the gadwall, shoveler, spotbill, common teal, lesser whistling duck, tufted duck, comb duck, cotton pygmy-goose, great cormorant, little cormorant, Indian shag, ruff, painted stork, white spoonbill, Asian open billed stork, black-headed ibis, oriental darter, common sandpiper, wood sandpiper and green sandpiper. 

Apart from the birds for which itis renowned, the Keoladeo National Park is also home to about 30 species of mammals, including the chital, sambar, nilgai, blackbuck, rhesus macaque, wild boar, Bengal fox, jackal, striped hyena, common palm civet, small Indian civet, crested porcupine, and Indian hare; 13 species of snakes including the python, cobra, krait and Russell’s viper; 5 lizards; 7turtles; and 7 amphibians.

COMBATING POLLUTION

Space debris

Space above Earth is turning progressively crowded. Space debris, or orbital debris, refers to the accumulation of non-operational items around Earth’s orbit, including old satellites, rocket stages that no longer operate, and pieces from collisions or explosions. As the number of space constellations and exploration grows at a never-before-seen rate, one question becomes important about space junk: This debris itself poses a great degree of danger to operational satellites, space missions, and other future exploratory undertakings. In these respects, battling orbital pollution is actually of the essence in order to guarantee that space operations are sustained appropriately for future generations.

Space debris refers to any human-made object that is no longer serving its functional purpose but still in Earth’s orbit. The sizes vary from tiny paint flecks to large and derelict satellites. The majority of the debris is housed in what is termed the Low Earth Orbit, which extends up to 2,000 kilometers above Earth’s surface. It is, particularly, pretty congested, as it is where most of the satellite operations take place: communication, Earth observation, and scientific research, among others. Some of the reasons why such buildups of space debris occur include the following: failed spacecraft, spent rocket stages, and fragments from explosions or collisions. The first significant awareness of the problem was the collision between the defunct Russian satellite Kosmos-2251 and an operational Iridium communications satellite back in 2009, adding several thousand fragments of debris into LEO. Since that accident happened, things have only gotten worse due to the increased number of launches.

Space debris poses a number of different risks to current and future space operations. Active satellites, space stations, and manned missions face the risk of being hit by debris with velocity mostly exceeding the speed of 28,000 kilometers per hour. In such great speed, even small fragments may cause serious damage: a paint chip is able to puncture the surface of a spacecraft, and collision with a big piece can destroy the whole satellite, thus contributing to the problem of debris. The Kessler Syndrome (1978), theorized by NASA scientist Donald Kessler, is an exponential growth cascade where space debris collides with satellites and other debris, creating fragments that collide further until possibly rendering parts of space unusable for decades or longer. Not yet collective, the Kessler Syndrome is a reason for concern due to the growing density of objects in LEO, which should be met with proactive measures.

Recently, the efforts to reduce space debris have been gaining momentum. Most of the efforts now go toward prevention rather than removal of debris. International guidelines such as those by UNOOSA and IADC, for instance, recommend designing satellites in such a way that they can deorbit no longer than 25 years after the end of their mission. This is often done by lowering their orbits so their re-entry into the atmosphere causes them to burn up. 

In addition, satellite operators are also summoned to carry out end-of-life maneuvers that safely remove those spacecraft from operational orbits. For geostationary satellites, that normally includes separation in a “graveyard orbit,” a place far away from the critical orbital zones where those defunct satellites can stay in without interfering with operational spacecraft.

While prevention is paramount, guidelines and best practices alone cannot solve the issue of the already existing debris.

ANCIENT LANGUAGES RICH IN LITERATURE

Classical Languages

The Union Cabinet has recently approved giving the status of ‘classical language’ to five more languages - Marathi, Bengali, Pali, Prakrit, and Assamese. With this cabinet decision, the number of languages that have the status will nearly double from six to 11. The languages that had the tag earlier were Tamil, Sanskrit, Telugu, Kannada, Malayalam, and Odia. Tamil was granted the status in 2004 and the last language to get it was Odia, in 2014. Prakrit and Pali are two distinct languages that have been derived from Sanskrit.

What is the criteria for a language to be recognised as classical?

The following criteria have to be met:

● High antiquity of the language’s early texts/recorded history over a period of 1,500-2,000 years.

● A body of ancient literature/texts, which is considered a heritage by generations of speakers.

● Knowledge texts, especially prose texts in addition to poetry, epigraphical and inscriptional evidence.

● The classical languages and literature could be distinct from their current form or could be discontinuous with later forms of their offshoots.
