Why National Science Day is celebrated?

 

It is our fundamental duty to develop a scientific spirit, says our Constitution. It’s, perhaps, the only Constitution in the world to say that. No wonder then that India has a dedicated day to celebrate science – the National Science Day. It is celebrated on February 28, to mark the discovery of light scattering – or the Raman Effect – by Nobel laureate Indian physicist, Sir CV Raman.

Nearly a century has passed by since the Raman Effect was discovered, revolutionizing the study of Physics and our understanding of the world. During this period, despite all the challenges and intermittent derailment of efforts, India has upheld its commitment to science, thanks to the efforts of successive generations of policymakers.

We have overcome a multitude of challenges, since our Independence, through the deployment of scientific solutions. India’s scientific community saved the country from the brink of starvation and famines through the Green Revolution. Today, India is a leading exporter of several agricultural commodities.

It also saved India from multiple health disasters. Polio and smallpox were effectively eradicated. An AIDS epidemic was brought under control. Maternal and Infant Mortality Rates were brought down by our health experts who worked with rural and urban poor communities to raise awareness and adopt medical procedures. Even during Covid-19, India was among the first few countries to indigenously produce a vaccine to control the pandemic

From a time when Western media and leaders mocked our space-tech ambitions, India has risen to challenge the Western hegemony over the skies and beyond. From being a defence equipment importer, we are now looking to export our products to other countries.

All of this was made possible through the advancement of science. India and Indians have been at the forefront of the IT and digital revolution. Engineers and technocrats from India lead several global technology corporations today. This has been possible because of the large-scale adoption of STEM education by Indians across the country.

According to the World Economic Forum, amid a global short supply, it’s India that is producing the highest number of STEM graduates in the world, year after year. Nearly 35% of all our graduates passing out of colleges have specialized in STEM subjects. They are major contributors to the global economy.

Yet, not all is hunky-dory. The changing socio-political climate has watered down the scientific temperament of the collective society. India ranks at 40th place in the global innovation index, while countries much smaller than us rank higher. Singapore, for instance, is ranked fifth.

While the deep science ecosystem has witnessed significant growth in the country, the scientific tools for sustainable development are yet to reach the hands of frontline communities. Scientific approach to problem-solving in other fields, such as public administration, city planning, and urban development is also lacking.

In this National Science Day special issue, we look at some of these pertinent topics. How students can inculcate scientific temper. What major deep-tech innovations are disrupting the Indian startup market. How space junk is a growing menace. Is India spending enough on Research and Development… We will be discussing these points in this Issue.

This Issue also has a curated set of articles written by scientists, educators, and research scholars. On the fun side, we look at the real-life experiment that inspired Mary Shelly to write the incredibly popular Frankenstein, and the common tropes on robots in books and movies. We hope this Issue inspires and entertains you in equal measure.

Where does sunbird live?

Tiny jewels with wings – that would describe sunbirds perfectly. As the bird flies busily, dipping its long, down-curved beak deep into the flowers to suck at the nectar, its feathers glint with a metallic sheen when the light catches it. The amazing thing is that tiny though it is (measuring 10-12 cm), you can count a number of colors – crimson, green, orange, blue, scarlet, yellow and mauve – in a single bird! And it is only the males which sport these colours. The females are generally drab olive green or dull brown. The males are bigger and have longer tails. Sunbirds are distantly related to honeyeaters and hummingbirds. They have the same habit of hovering before a flower, their wings a blur of movement. Sometimes they hang upside-down, pushing their tube-like furry tongues into the centre of flowers which are trumpet-shaped or bell-shaped.

Nests are small, delicate cups, constructed mostly of cobwebs with a few strands of dried grass thrown in. Up to four tiny eggs are laid. Both male and female take turns in feeding the young.

There are 12 species of sunbirds in India and the commonest is the purple sunbird.

What is the name of the smallest bear in the world?

The sun bear is the smallest bear species in the world. It gets its name from the yellow or creamy white mark on its chest that resembles the rising sun. It is also known as the Malayan bear.

Compared to the biggest bear species – the polar bear and the Kodiak or grizzly bear, which stand almost 3 metres (9.8 feet) tall and weigh around 635 kilos, the sun bear grows to about 1.2 metres (36 cm) in length and weighs around 40 kilos. It has a black coat and a light grey or orange nose. The feet are tipped with long sickle-shaped claws, which are sharper and curvier than in most other bear species. The soles are hairless.

Sun bears build nests in trees by breaking or bending the branches. They spend the day in the nests, sleeping and basking. They hunt only at night.

In 1978, the IUCN included the sun bear in its Red List of endangered species. Although its population has decreased due to hunting, a few thousand can still be found in the forests of the Malay Peninsula, Java, Sumatra, Myanmar, Borneo and Thailand.

Why are stonefish so poisonous?

Stonefish is perhaps one of the world’s best camouflaged fish. But it is also the most venomous. Found in shallow waters of the tropical Indo-Pacific, stonefish stay in the muddy or rocky bottoms of marine environments, living among rocks or coral. It may look like a stone on the ocean floor and deceptively stays blended with the ocean floor while hunting. The skin covered by wart-like lumps helps it in camouflage. It has venomous spines and when stepped on accidentally or there is a contact, it can sting. The sting is painful and can be fatal. Did you know that the fish is a delicacy in certain parts of Asia after its venomous spines are removed.

What is a venomous lizard native to parts of the US and Mexico?

Native to the USA and Mexico, the Gila monster is a small, venomous lizard that is known to spend more than 90% of its life below the ground. As such you may not encounter the Gila monsters in the wild but bites are known to occur at times. The venomous lizard is known to use its venom only for defensive purposes. A mild neurotoxin, the venom of the creature is produced in the lizards’ salivary glands. The saliva is toxic and is found to contain the hormone exendin-4 which could be used to treat type 2 diabetes. Although its venom is deadly, it also has potential medicinal use. While the lizard is strictly nocturnal, above-ground sightings of it are also seen during the day.

Why is the box jellyfish so dangerous?

 

BOX JELLYFISH

The box jellyfish can perhaps be regarded as one of the most dangerous animals in the sea because of the deadly venom produced by some species. They dwell in the warm coastal marine waters. The deadliest species is the Chironex fleckeri or the Australian box jellyfish. It is also the largest species among the box jellyfish. The venom is considered deadly because of the toxins that can attack the nervous system, skin and heart. Death is known to occur quickly. Also called sea wasps and marine stingers, the box jellyfish are pale blue and transparent in colour. One look at the marine creature and you will know why it received the unique name. The distinct cube-like shape of their bell is how the name came about. Another interesting fact about box jellyfish is that they are highly advanced when compared to other jellyfish rather than drifting. They have developed the ability to move.

Is the inland or western taipan oxyuranus microlepidotus?

Native to central Australia, the Inland Taipan snake usually lives in desert areas. Also called a fierce snake, the Inland Taipan is the world’s most venomous snake. The venom of the snake is very potent with experts noting that a drop of the snake’s venom is enough to kill 100 people. The snake is quite shy and encounters with humans are rare. The venom is so powerful that it could kill the victim within hours if medical treatment is not given.

What is a mother tongue and why is it called so?

A mother tongue, also known as a native language or first language, is the language that a person learns from birth or infancy within their family or community environment. It is called a mother tongue because it is typically taught by the mother or primary caregivers within the family setting. The term “mother tongue” (although a bit old-fashioned) emphasizes the intimate connection between a person’s language and their familial and cultural background. It represents the language that is passed down from generation to generation within a particular community or cultural group, shaping the individual’s identity, communication skills, and cultural heritage.

When does a language die?                                                                                     According to UNESCO, it is estimated that more than 40% of the approximately 7,000 languages spoken worldwide are endangered or at risk of extinction if no efforts are made to preserve and revitalise them. This means that over 2,800 languages are in danger of disappearing. Languages that have either no native speakers left or are on the verge of extinction, with very few speakers remaining are called dead or dying languages.

Why are languages dying?

The United Nations suggests that several factors influence the status and retention of a language within a community like:

• Poverty: In economically disadvantaged areas, access to education and resources may be limited, leading to lower levels of literacy and language proficiency. As a result speakers of minority or indigenous languages in impoverished regions may face challenges in preserving and transmitting their languages to future generations. Economic disparities can also contribute to language shift, as speakers may prioritise leaming the dominant language of the majority population in order to access opportunities for education, employment, and social mobility.

• Migration: When individuals or groups migrate to new countries or regions, they often encounter linguistic diversity and may need to leam the language(s) of the host society in order to communicate and integrate effectively. This can lead to language shift, particularly among second or thing-generation immigrants who may prioritise the majority language(s) for social, economic, and educational reasons.

• Complexity of language syntax the syntactic complexity of a language can influence its status and retention within a community. In communities facing socio-economic challenges or undergoing rapid socio-cultural changes, languages with difficult syntax may be perceived as barriers to communication, education, and social mobility. As a result, speakers may gradually shift towards simpler or more widely spoken languages that offer greater accessibility and utility in everyday interactions.

A mother tongue is crucial for a child’s all-round development

• Cognitive development: Research suggests that children who are proficient in their mother tongue tend to develop stronger cognitive skills, including problem-solving, critical thinking, and memory retention. This foundation in their first language provides a scaffold for learning additional languages and academic subjects.

• Emotional connection: The mother tongue is closely linked to a child’s sense of identity, culture, and belonging. It forms the basis of communication within the family unit, fostering emotional connections and a sense of security when children are able to express themselves fluently in their mother tongue, they feel validated and understood which contributes to their overall well-being. Moreover, this connection to their cultural heritage instills a sense of pride and appreciation for diversity, fostering cultural continuity and resilience.

• Academic success: Research suggests that kids who receive education in their first language often perform better in school, as they are able to grasp complex concepts more easily and engage more actively in learning activities. Additionally, a strong foundation in the mother tongue provides a smoother transition to learning additional languages.

How Do We Save Our Mother Tongues

To safeguard our mother tongues, it is imperative that we take proactive measures. Parents can play a crucial role by introducing their children to rhymes and stories from their native languages. Teachers should advocate for linguistically appropriate curricula, particularly by prioritizing early education in mother languages. In 1999, countries globally adopted a resolution promoting multilingual education, yet the implementation often falls short. While schools mandate learning three languages, the focus on regional languages is often minimal. Shockingly, 40% of people worldwide lack access to education in their native language, leading to marginalized communities avoiding schools altogether. To address this, we must raise awareness and strive for more inclusive educational policies that honors and preserve our rich linguistic heritage.

What are the characteristics of a slow loris?

SLOW LORIS

With its big eyes and cute face, slow Loris is perhaps one of the most adorable creatures in the wild. But it is also the world’s only venomous primate. Native to the rainforests of South and Southeast Asia, the slow loris lives in trees. These lethal furballs are known for their bites that are loaded with venom. The animal’s venom gets activated when its saliva mixes with an oil that is secreted by the gland on its upper arm. When threatened, the slow loris raises its arm. It then licks the gland and the saliva and oil mix produces the venom, which then goes to the animal’s canines and is delivered to the victim through a bite. Its venom is said to cause anaphylactic shock and even death in humans...
