GS Paper: GS3-16.Achievements of Indians in Science & Technology

  • Black Hole, Resolving the Mistry

    Black Hole

    Context

    • For the very first time, scientists noted that this observation of the Laser Interferometer Gravitational Wave (LIGO) observatories coincided with the measurements made by other telescopes that measured visual and electromagnetic signals.

    What is Black hole?

    • A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
    • Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

    Black Hole

    What is the background?

    • LIGO Observations: In 2017, astrophysicists observed an unusual feat among the stars. The Laser Interferometer Gravitational Wave(LIGO)observatories recorded a signal which indicated that two massive and dense stellar bodies had merged to form a third body, likely a black hole.
    • Generation gravitational waves: In the process they gave off vibrations that quite literally shook the universe and its very fabric of space time.
    • Neutron stars: Scientists, piecing together evidence from complementary measurements, surmised that the event they had observed was of two neutron stars merging and forming a black hole and, in the process, giving off light.

    Black Hole

    What are the observations through telescopes?

    • The matter moving faster than light: An unusual jet of matter was observed that gave an illusion of travelling faster than light. These were all exciting phenomena observed for the very first time by telescopes and observatories.
    • Confirmation by Hubble Space Telescope: Now, using data that had been recorded by the Global astro metric Interferometer for Astrophysics (GAIA) spacecraft and Hubble Space Telescope instruments, scientists have confirmed that the above picture is correct. They have made it more precise and descriptive.
    • Seven times the speed of light: In a paper published in Nature, they describe measuring the “apparent speed” of the jet to be about seven times the speed of light.
    • Lorenz factor: They have also measured more accurately a factor called the Lorenz factor which scales with the actual speed of the particles in the jet. Unlike earlier estimates which placed this factor at about 4, the present paper estimates this factor to be over 40. This is because they measure the speed of the relativistic jet to be close to 0.9997c, where “c” is the speed of light.
    • Clarity about the source as neutron star in block hole generation: This resolves the earlier fuzziness about what the source was and puts the source clearly as massive neutron stars merging to give a black hole and throwing off relativistic jets of particles in the process.

    Black Hole

    Merging of Neutron stars

    • Born out of Supernova explosion: Neutron stars are stellar corpses, left behind after a star has undergone a supernova explosion and reached the end of its lifetime. They are extremely dense, containing more mass than the sun in a sphere that is a few tens of kilometre wide.
    • Produces fast moving material: This has been seen in many active galactic nuclei  galaxy centres that harbour black holes and binary star systems within our galaxy, where one of the stars is a black hole. “Mostly, black holes are responsible for producing such fast moving material

    Why present observations about black Hole are significant?

    • Estimating changing position of sky: The present measurements and observations made with GAIA data are extremely challenging. They amount to measuring the position of an object in sky coordinates. These authors measured a change in sky position one millionth the span of the full moon. Normally, if one were making these measurements from earth-based telescopes, it would require data from radio telescopes spaced apart by intercontinental distances.
    • VLBI technique: This technique is called Very Long Baseline Interferometry (VLBI) and was used in the earlier papers. “Here, the authors could beat VLBI in precision because they calibrated Hubble Space Telescope data with GAIA, which is a precision astrometry mission.
    • It’s an estimate not a measurement: the researchers used both their Hubble Space Telescope and GAIA optical position measurement along with the earlier VLBI position measurement to get a better estimate of the speed of the source and angle (viewing angle) with which it is travelling with respect to us on earth. This estimate requires plugging in equations of the special theory of relativity. “So, it is an estimate as opposed to a measurement.
    • Improvement in estimation: we have learnt that neutron star mergers can result in material moving with speeds as high as 0.9997c.Earlier results using Very Long Baseline Interferometry had pegged this value at about 0.938c. with the new results this lower limit has been improved. Even earlier, with VLBI, it was understood that it was a neutron star merger that produced such ultra-relativistic material. Before the VLBI results, there were several models that could replicate the observations.
    • Explanation using ultra realistic material: The observations could be explained both by ultra-relativistic material and non relativistic material, with some differences in assumptions. That study indicated that the observed gamma ray bursts were produced along with the ultra-relativistic material.

    Conclusion

    • Current discovery strengthens the hypothesis that such neutron star mergers are responsible for a class of gamma ray bursts. Gamma ray bursts are flashes of extreme gamma ray photons that release a huge amount of energy nearly 1047 They come from different galaxies in the universe and are observed here quite frequently.

    Mains Question

    Q. What is the neutron star and how the merger of two stars produces a black hole? How LIGO and Hubble space telescope are useful in demystifying the black Hole phenomenon?

  • Dr. Mahalanabis: the man behind ORS no more

    ors

    While Oral Rehydration Solution (ORS) as a simple, effective remedy for dehydration is known around the world, the physician who pioneered the treatment, Dr. Dilip Mahalanabis, passed away.

    What is ORS?

    • Oral rehydration therapy is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhea.
    • It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium.
    • Oral rehydration therapy can also be given by a nasogastric tube.

    About Dr. Mahalanabis

    • Born on November 12, 1934 in West Bengal, Dr Mahalanabis studied in Kolkata and London.
    • He joined the Johns Hopkins University International Centre for Medical Research and Training in Kolkata in the 1960s, where he carried out research in oral rehydration therapy.
    • When the 1971 war broke out, millions of people from then East Pakistan took refuge in India.
    • Clean drinking water and sanitation were problems at these refugee camps, and cholera and diarrhoea broke out among people anyway exhausted and dehydrated.
    • Dr Mahalanabis and his team were working in one such camp at Bongaon.
    • Stocks of intravenous fluids were running out, on top of which there weren’t enough trained personnel to administer the IV treatment.

    How he discovered ORS?

    • From his research, Dr Mahalanabis knew that a solution of sugar and salt, which would increase water absorption by the body, could save lives from Cholera.
    • He and his team then prepared solutions of salt and glucose in water and began storing them in large drums, from where patients or their relatives could help themselves.
    • The oral solution then consisted of 22 gm glucose (as commercial monohydrate), 3.5 gm sodium chloride (as table salt) and 2.5 gm sodium bicarbonate (as baking soda) per liter of water.
    • This was the simplest formula, containing the minimum number of ingredients, previously found to be effective in severely ill patients with cholera.

    His legacy

    • While initially, the medical fraternity was septical, the WHO eventually adopted ORS as the standard method for treating cholera and other diarrhoeal diseases.
    • Today, the WHO recommends a combination of sodium chloride, anhydrous glucose, potassium chloride and Trisodium citrate dihydrate as the ORS formula.
    • In India, July 29 is observed as ORS Day.

  • India’s Dark Sky Reserve

    Dark Sky ReserveContext

    • The union territory of Ladakh will host India’s first Dark Sky Reserve which will be set up in Hanle area in the next three months. The Dark Sky Reserve is being built as part of Ladakh’s high-altitude Changthang Wildlife Sanctuary.

    What is Dark Sky Reserve (DSR)?

    • Definition of Dark Sky Reserve: The International Dark Sky Association (IDSA) defines an international dark sky reserve (IDSR) as “a public or private land of substantial size (at least 700 km², or about 173,000 acres) possessing an exceptional or distinguished quality of starry nights and nocturnal environment, and that is specifically protected for its scientific, natural, educational, cultural heritage, and/or public enjoyment.

    What is Core Area of Dark Sky Reserve?

    • A dark sky reserve requires a “core” area that has clear sky without any light pollution, which can enable telescopes to see the sky in its natural darkness.

    Dark Sky Reserve

    Why Ladakh is chosen as ideal location for DSR?

    • Ladakh is ideal for long-term observatories and dark-sky sites because of its large arid area, high elevation, and sparse population, extreme cold and minimum temperature drops to minus 40 degree celcius.
    • The Changthang wildlife Sanctuary, the DSR site is situated around 4,500 metres above sea level, which makes it a perfect host for telescopes.

    Who is managing India’s DSR?

    • The Department of Science and Technology and Indian Institute of Astrophysics (IIA) in Bengaluru are providing support for the facility. The IIA already manages the Indian Astronomical Observatory (IAO) complex in Hanle, Ladakh.

    What are the International standards for DSR?

    • International Dark Sky Association’s Recognition: The IDSA recognizes and accredits dark-sky areas worldwide, in three categories. The Mont Mégantic Observatory in Quebec is the first such site to be recognized (in 2007) as an International Dark Sky Reserve.
    • Categorical Certification: Individuals or groups can nominate a site for certification to the International Dark Sky Association (IDSA). There are five designated categories, namely International Dark Sky parks, communities, reserves, sanctuaries and Urban Night Sky Places.
    • Global Recognition: The certification process is similar to that of a site being awarded the UNESCO World Heritage Site tag or getting recognised as a Biosphere Reserve. Between 2001 and January 2022, there have been 195 sites recognised as International Dark Sky Places globally, the IDSA said.
    • Dark Sky Park: IDSA recognized Natural Bridges National Monument in Utah as the world’s first International Dark Sky Park.
    • Dark Sky Sanctuary: In 2015, the IDSA introduced the term “Dark Sky Sanctuary” and designated the Elqui Valley of northern Chile as the world’s first International Dark Sky Sanctuary. The Gabriela Mistral Dark Sky Sanctuary is named after a Chilean poet.

    Dark Sky ReserveWhat is India’s objective with DSR?

    • To promote AstroTourism: The primary objective of the proposed Dark Sky Reserve is to promote astronomy tourism in a sustainable and environment-friendly manner. Scientific methods will be used here to preserve the night sky from ever-increasing light pollution.
    • To offer clear skies for observations: With metros, cities and peripheral areas experiencing light pollution and remaining constantly lit up, there are diminishing areas that offer a view of clear skies on cloudless nights.
    • For training purpose: In the pilot phase, the Indian Institute of Astrophysics (IIA),has procured ten small and easy-to-handle telescopes and light-reflecting shields. IIA’s scientists and outreach experts will identify locals and train them to use these telescopes.
    • Sky gazing and a boost for village economy: This will include basic sky gazing, identification of constellations, and locating the pole star, among others. These telescopes will be installed at the homestays, which is a popular option for tourist accommodation in Ladakh.

    Dark Sky ReserveConclusion

    • The Dark Sky Reserve is likely to boost Astro tourism in India where there has been no such reserve. Once set up, the reserve will be the highest-located site in the country for infrared, gamma-ray, and optical telescopes.

    Mains Question

    Q. What are the Dark Sky Reserves? How DRS will help in astronomical research and observations in India?

  • Places in news: Ram Setu

    ram setu

    A movie has once again generated buzz around the chain of shoals off the southeast coast of India that many believe is the Ram Setu or the bridge to Lanka mentioned in the Ramayana.

    The Ram Setu

    • The Ram Setu, also known as Adam’s Bridge, is a 48-km chain of limestone shoals between Rameswaram on India’s southeast coast and Mannar Island near Sri Lanka’s northwest coast.
    • The structure has significance in both Hindu and Muslim mythology – while Hindus believe this is the bridge (Setu) built by Lord Ram and his army to cross to Lanka and fight Ravan.
    • As per Islamic legend, Adam used this bridge to reach Adam’s Peak in Sri Lanka, where he stood on one foot for 1,000 years in repentance.

    Factual details of the bridge

    • Scientists believe Ram Setu is a natural structure formed due to tectonic movements and sand getting trapped in corals.
    • However, over the years, evidence has been offered to claim that the bridge is man-made.
    • The bridge is not entirely natural, Hindu right wing outfits argue, which proves that it was indeed built by Lord Ram.

    When was the structure came into highlights?

    • The Ram Setu issue snowballed into a major controversy when the Sethusamudram Project, flagged off during the UPA I government.
    • The project aimed to reduce travel time between the eastern and western coasts of India, as ships would no longer have to circle Sri Lanka to travel between the Bay of Bengal and Arabian Sea.
    • The project was perceived as an attack on Hindu sentiments.
    • Various studies have been proposed on the Ram Setu, with the most recent being in 2021, when the government approved an underwater research project to ascertain its origins.

    Ecological arguments against the project

    • The Sethusamudram project has been opposed on environmental grounds.
    • Some claims that it will harm marine life, and that dredging of the line of shoals will make India’s coast more vulnerable to tsunamis.
    • In March 2018, the Centre told the Supreme Court that the Ram Setu will not be affected in the execution of the Sethusamudram Shipping Canal project.

    NASA images, and other proofs

    • Images of the Ram Setu clicked by NASA have been used over and over again to claim that this proves the existence of a man-made bridge.
    • NASA has repeatedly clarified that it does not agree with these claims.
    • Remote sensing images or photographs from orbit cannot provide direct information about the origin or age of a chain of islands.
    • It certainly cannot be determined whether humans were involved in producing any of the patterns seen.

  • Centre’s push for NavIC System  

    navic

    The Union government is pushing tech giants to make smartphones compatible with its home-grown navigation system ‘NavIC’.

    What is NavIC?

    • NavIC, or Navigation with Indian Constellation, is an independent stand-alone navigation satellite system developed by the Indian Space Research Organisation (ISRO).
    • NavIC was originally approved in 2006 at a cost of $174 million.
    • It was expected to be completed by late 2011, but only became operational in 2018.
    • NavIC consists of eight satellites and covers the whole of India’s landmass and up to 1,500 km (930 miles) from its boundaries.

    Note: The numbers of satellites in this constellation is disputed. It is given as 7 and 8 on different sources. Total Nine satellites were launched out of which the very first (IRNSS-1A) is partially failed because of some issue in its Atomic Clock. Another and the last satellite had a launch failure. Hence the number 7/8.

    Why is the Centre pushing for NavIC?

    • Currently, NavIC’s use is limited.
    • It is being used in public vehicle tracking in India.
    • It helps providing emergency warning alerts to fishermen venturing into the deep sea where there is no terrestrial network connectivity, and for tracking and providing information related to natural disasters.
    • Enabling it in smartphones is the next step India is pushing for.
    • India’s 2021 satellite navigation draft policy stated the government will work towards expanding the coverage from regional to global to ensure availability of NavIC signal in any part of the world.

    How does NavIC compare?

    • The main difference is the serviceable area covered by these systems.
    • GPS caters to users across the globe and its satellites circle the earth twice a day, while NavIC is currently for use in India and adjacent areas.
    • Like GPS, there are three more navigation systems that have global coverage – Galileo from the European Union, Russia-owned GLONASS and China’s Beidou.
    • QZSS, operated by Japan, is another regional navigation system covering Asia-Oceania region, with a focus on Japan.

    Strategic significance of NavIC

    • India says NavIC is conceived with the aim of removing dependence on foreign satellite systems for navigation service requirements, particularly for “strategic sectors.”
    • Relying on systems like GPS and GLONASS may not always be reliable, India says, as those are operated by the defence agencies of respective nations.
    • It is possible that civilian services can be degraded or denied.
    • NavIC is an indigenous positioning system that is under Indian control.
    • There is no risk of the service being withdrawn or denied in a given situation.

  • ISRO tests system recoverable rocket ‘Inflatable Aerodynamic Decelerator (IAD)’

    The Indian Space Research Organisation (ISRO) has successfully tested a technology that could aid the cost-effective recovery of spent rocket stages and safely land payloads on other planets.

    What is IAD?

    • IAD is a technique used for an atmospheric entry payload.
    • An inflatable envelope and an inflatant (anything that inflates the envelope, like air or helium) make up the inflatable aerodynamic decelerator.
    • While entering the atmosphere, it inflates like a balloon and decelerates the lander.
    • The inflatant is designed to fill the inflatable envelope to a condition such that it surrounds the payload meant to enter the atmosphere of a planet or satellite and causes aerodynamic forces to slow it down.
    • In simpler words, IAD is designed to increase drag upon entering the atmosphere of any planetary body, like Earth, Mars, or even Moon.
    • Its shape is maintained by a closed, gas-pressured body and the inflatant gas is also generated internally. Some versions also use ram air or both.

    How significant is this IAD?

    • Some space agencies, including NASA, have already successfully tested advanced versions of the technology, including the supersonic and hypersonic variants.
    • However, for near future missions of ISRO, the current version that it tested is perfect.
    • Its use was first proposed by NASA more than 50 years ago for planetary entries.

    Minuscule of ISRO’s IAD

    • The IAD tested by ISRO was inflated at an altitude of around 84 km and the sounding rocket’s cargo dropped through the atmosphere on it.
    • It is fitted with a booster motor. It also has a spin rocket that is ejectable.
    • The inflatable structure is made out of Kevlar fabric, which is a very strong synthetic fibre and also heat resistant to withstand atmospheric pressure and temperature changes.
    • On top of it, it’s coated with polychloroprene, an oil and wax resistant rubber, to withstand extreme temperatures.
    • In the inflation system, it uses compressed nitrogen stored in a bottle.
    • It has consistently decreased the payload’s velocity through aerodynamic drag while maintaining the expected trajectory during the test flight.

    Where does ISRO intend to use it?

    • The IAD will help ISRO in performing many space tasks effectively including recovery of spent stages of rockets, for landing payloads on missions to other planetary bodies.
    • This is the first instance where an IAD has been specially created for spent stage recovery.
    • So inter-planetary missions are certainly one aspect that ISRO wishes to explore.

  • Cervavac: India’s first indigenously developed Vaccine for Cervical Cancer

    Cervavax

    Union Minister of Science and Technology has announced the scientific completion of Cervavac, India’s first indigenously developed quadrivalent human papillomavirus (qHPV) vaccine for the prevention of cervical cancer.

    What is Cervavac?

    • Cervavac was developed by the Pune-based Serum Institute of India in coordination with the Department of Biotechnology (DBT).
    • The project to develop the vaccine was implemented by the then secretary of the DBT, Dr. M K Bhan in 2011.
    • Since then, 30 meetings of scientific advisory groups and site visits conducted by DBT have helped review the scientific merit of the entire journey to develop the vaccine.
    • Cervavac received market authorisation approval from the Drug Controller General of India on July 12 this year.

    What is so unique about Cervavac?

    • HPV vaccines are given in two doses and data has shown that the antibodies that develop after both are administered can last up to six or seven years.
    • Unlike Covid vaccines, booster shots may not be required for the cervical cancer vaccine.
    • Until now, the HPV vaccines available in India were produced by foreign manufacturers at an approximate cost of Rs 2,000 to Rs 3,500 per dose.
    • Cervavac is likely to be significantly cheaper, slated to cost approximately Rs 200 to 400.
    • It has also demonstrated a robust antibody response that is nearly 1,000 times higher than the baseline against all targeted HPV types and in all dose and age groups.

    Significance of the vaccine

    • Despite being largely preventable, cervical cancer is the fourth most common cancer among women globally, according to the WHO.
    • In 2018, an estimated 57000 women were diagnosed with the disease and it accounted for 311,000 deaths across the world.

    How common is cervical cancer in India?

    • India accounts for about a fifth of the global burden of cervical cancer, with 1.23 lakh cases and around 67,000 deaths per year.
    • Almost all cervical cancer cases are linked to certain strains of human papillomavirus (HPV), a common virus that is transmitted through sexual contact.
    • The body’s immune system usually gets rid of the HPV infection naturally within two years.
    • However, in a small percentage of people, the virus can linger over time and turn some normal cells into abnormal cells and then cancer.

    How dangerous is cervical cancer?

    • Cervical cancer is preventable if detected early and managed effectively.
    • Screening and vaccination are two powerful tools that are available for preventing cervical cancer.
    • Still, there is little awareness among women about the prevention of this cancer and less than 10% of Indian women get screened.
    • All women aged 30-49 must get screened for cervical cancer even if they have no symptoms and get their adolescent daughters vaccinated with the HPV vaccine.

    What are the challenges?

    • The biggest task will be in allocating adequate resources and manpower for vaccinating the massive demographic of adolescent girls aged between 9 and 15, to ensure that they are protected from HPV early.
    • There is a huge need for stepping up awareness about the disease and the vaccine in the community.
    • Unlike Covid and the vaccination programme, there is very little awareness about cervical cancer.
    • Overall awareness and screening are very low in the community and that is a concern.
    • Since this is a preventable disease and hence a huge awareness programme is required

    Way forward

    • School-based vaccination programmes might work effectively.
    • Currently, none exist and therefore planning will have to be done along those lines.
    • Those accessing public health programmes will get the vaccine free of cost at government-aided schools.
    • However concerted efforts will have to be made to ensure the involvement of private healthcare facilities and NGOs towards an effective rollout.

  • Solar energy & India

     

    Context

    • Tesla and SpaceX CEO Elon Musk has said that civilisation will be mostly solar-powered in the future, a world without Sun will turn into a dark ice ball as the Earth gets all of its energy from it.

    Definition of solar energy

    • Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy, and solar architecture.

    India’s solar target.

    • Target: India is targeting about 500 GW by 2030, of renewable energy deployment, out of which ~280 GW is expected from solar PV. This necessitates the deployment of nearly 30 GW of solar capacity every year until 2030.
    • Commitment: Solar power is a major prong of India’s commitment to address global warming according to the terms of the Paris Agreement, as well as achieving net zero, or no net carbon emissions, by 2070.

    International solar alliance and India’s pledge

    • Climate action commitment: It symbolizes about the sincerity of the developing nations towards their concern about climate change and to switch to a low-carbon growth path.
    • Clean energy: India’s pledge to the Paris summit offered to bring 40% of its electricity generation capacity from non-fossil sources (renewable, large hydro, and nuclear) by 2030.
    • Global electrification: India has pledged to let solar energy reach to the most unconnected villages and communities and also towards creating a clean planet.
    • Global cooperation: It is based on world cooperation irrespective of global boundaries.
    • India’s Soft power: For India, possible additional benefits from the alliance can be a strengthening of ties with the major African countries and increasing goodwill for India among them.

    Some Interesting facts

    Solar power is the most abundant energy source on earth.

    Solar is the cheapest source of energy in the world.

    Solar electricity has been around since 1839.

    Solar panels can produce power without direct sunlight.

    Challenges before solar future

    • High Imports: Indian solar deployment or installation companies depend heavily on imports. It currently imports 100% of silicon wafers and around 80% of cells even at the current deployment levels.
    • Field deployment: Also, out of the 15 GW of module manufacturing capacity, only 3-4 GW of modules are technologically competitive and worthy of deployment in grid-based projects.
    • Land issue: Land, the most expensive part of solar projects, is scarce in India — and Indian industry has no choice but to move towards newer and superior technologies as part of expansion plans.
    • Lack of investment: India has hardly invested in this sector which can help the industry to try and test the technologies in a cost-effective manner.

    Way forward

    • Supportive policies and innovative technological approaches are needed for the sector to achieve its potential.
    • Indian policymakers need to plan for rooftop solar plus storage, rather than rooftop solar alone with the grid as storage (net / gross metering).
    • The declining cost of storage solutions, along with that of rooftop solar solutions, is likely to change the future of the Indian power sector.

    Conclusion

    • In the foreseeable future, one can witness a just and equitable energy order if solar energy, along with other forms of renewable energy, can be harnessed more positively.

    Mains question

    Q. Fossil fuels have a 60% share in India’s total energy mix in this context discuss solar future for India with challenges for the same.

  • Scientific temper

    Context

    • India has not produced any Nobel Prize winner in science in the last 85 years — largely because of the lack of a scientific environment in the country.

    What is scientific temper?

    • Jawaharlal Nehru coined the term ‘scientific temper’; he defines it as an attitude of logical and rational thinking. An individual is considered to have scientific temper if she employs the scientific method when making decisions.

    Why it is important?

    • Scientific temper is very important for bringing forth a progressive society. It is free from superstitions. Irrational practices in developing the nation are in all aspects like political, economic and social.

    Its components

    • The vital parts of scientific temper are discussion, argument, and analysis. Various elements like fairness, equality, and democracy. The most important characteristic of a scientific temper is: – untiring search for truth with an open mind and spirit of inquiry.

    Constitutional mandate of scientific temper

    • In 1976, the Government of India reemphasised its commitment to cultivate scientific temper through a constitutional amendment (Article 51A).
    • Article 51A in the 42nd Amendment of the Constitution in 1976 says “It shall be the duty of every citizen of Indian to develop the scientific temper, humanism and the spirit of enquiry and reform.”

    Importance of scientific temper in nation building

    • Formation of public policy: Scientific temperament can become a part of the policy formation and plan through analyzing the performance of our nations, especially all the hardships and shortfalls that occurred in the past years.
    • Self -Reliance: There is a relationship between scientific temperament and becoming self-reliant. Our country is becoming self-reliant with the available technology and industrial infrastructure.
    • Quality education: It will help the children to assimilate the knowledge acquired through the practical observations in a scientific framework; thus, laying down a basis for the growth of a scientific perspective in the children.

    scientific temperChallenges before scientific temper

    • Political unwillingness: Most of the policymakers and the politicians to increase their vote banks include the stagnant ideologies and beliefs of the people in their public policies, and the government tends to give away in the popular public opinion rather than try to improve their thinking by including a more scientific approach to the various societal problems.
    • Prevalent orthodoxy: In India, people still have an orthodox ideology and will not adhere to the scientifically obtained solutions.
    • Low budget: Even after seventy years of independence, Indian Scientists are working on tight budgets, and they don’t have resources like other nations for conducting scientific research.
    • Pseudoscience: Pseudoscience is everywhere, whether in denying the science of climate change or the evolution theory that explains the secret of diversity that we see around us.

    Value addition / case study / Innovation

    An IIT Kanpur alumni Mr.Arvind Gupta tries to inculcate a spirit of inquiry among children through toys made from inexpensive everyday items.


    What can be done?

    • Directional efforts: Activities focused on school children can be undertaken like nature walks, visit to museums etc. ‘Science Express’, a collaborative effort of Ministry of railways and Ministry of Environment & Forests & Climate Change, is a progressive step because it provides a platform that can expose children and common people in far-flung areas of the country to scientific aspects of our everday life.
    • Policy initiatives: Children’s Science Congress organized by National Council for Science & Technology Communication (NCSTC) is a good way to encourage scientific temper in children.
    • Public initiative: Civil Society organizations like, Kerala Sastra Sahitya Parishad (KSSP) and Delhi Science Forum, which are People’s Science Movement, can also go a long way in boosting scientific temper amongst the community.
    • From Sensationalism to Sensible Science Journalism:The media must monitor the content to discourage and limit superstition and blind belief.
    • Scientific journalism: Science communicators do the critical job of bridging the gap between science, society, and policymakers. Science journalism should be promoted at the university level. Science agencies should fund science communication activities in their domains.
    • From Exclusive to Inclusive Science: Inequitable participation concerning gender and social diversity must be eliminated. The ‘open source science’ or ‘open science’ movement includes, at the core, open access, open data, open-source, and available standards that offer unfettered dissemination of scientific discourse.
    • Open science: Government has a significant role in facilitating open science and promoting and preserving a free-thinking, open-minded society.

    Conclusion

    • Let’s hope that someday all cultures free themselves from the shackles of blind faith  with science likely to play a major hand in this endeavour. Unto a similar goal, we should celebrate India’s constitutional provision for the scientific temper and vigorously safeguard it.

    • Dr Shanti Swarup Bhatnagar
    • He was the Founder Director (and later first Director-General) of CSIR who is credited with establishing twelve national laboratories. He played a significant role in the building of post-independent Science and Technology infrastructure and in the formulation of India’s S & T policies

    CSIR’s Vision

    • “Pursue science which strives for global impact, technology that enables innovation – driven industry and nurture trans-disciplinary leadership thereby catalyzing inclusive economic development for the people of India”

    Why CSIR is important?

    • Innovation: Regarding intellectual property, the CSIR has over 2971 patents filed internationally with 1592 patents filed in India. Since its inception in 1942 over 14000 patents have been granted worldwide. It was awarded the National Intellectual Property Award in 2018 by the India Patent Office.
    • Pandemic handling: CSIR identified the unmet needs, assessed its strengths and capabilities for addressing the pandemic and adopted a multi-pronged strategy of working on diagnostics, surveillance, drugs, hospital assistive devices, personal protective equipment and supply chain and logistics. This strategy is now beginning to yield exciting solutions.

    Contribution of CSIR

    Strategic Sector

    • Head-Up-Display (HUD) In high-tech areas, CSIR-NAL made significant contribution by developing indigenous Head-Up- display(HUD) for Indian Light Combat Aircraft, Tejas. HUD aids the pilot in flying the aircraft and in critical flight maneuvers including weapon aiming.

    Some of the challenges faced for sustainable growth of R&D in India are

    • Low research professionals: India has an estimated full-time equivalent R&D professional strength of only 150 professionals per million, compared to that of other countries.
    • Low investment: Indian research is mostly skewed towards basic research and lacks in application oriented R&D. The vast majority of organizations would rather go for quick acquisition of technology rather than invest in internal R&D.
    • IPR enforcement: Inadequate enforcement of intellectual property rights (IPR). While India has improved its IPR regime, the protection of intellectual property remains weak in some areas owing to inadequate laws and ineffective enforcement.

    Some positive suggestions to improve innovation

    • Embrace technology: Technologies, such as machine learning, can be used to improve R&D decision-making. Documents need to be filed throughout the R&D process, for example, and the process could be automated to free up employees to do more complex tasks.
    • Invest in innovation hubs: Companies that invest in innovation hubs expand talent and relationships with local universities and startups can support a two-way learning process and faster innovation cycles.
    • Promoting startups: Most radical innovations are coming from startups and more of them are needed. Tilting higher education towards science and encouraging more students to take degrees in science-based subjects can provide the people needed for R&D.

    Conclusion

    India is a strong contender in the field of Global R&D. For India to derive maximum growth and sustainability of R&D, its R&D fundamentals have to be strong and excellent.
