  • Abel Prize awarded to American Mathematician

    The Norwegian Academy of Science and Letters has awarded the Abel prize for the year 2022 to American Mathematician Dennis Parnell Sullivan, for his contributions to topology in its broadest sense, and in particular its algebraic, geometric and dynamical aspects.

    Abel Prize

    • The Abel Prize is a prize awarded annually by the King of Norway to one or more outstanding mathematicians.
    • It is named after Norwegian mathematician Niels Henrik Abel (1802–1829) and directly modeled after the Nobel Prizes.
    • It comes with a monetary award of 7.5 million Norwegian kroner (NOK) (increased from 6 million NOK in 2019).
    • Its establishment was proposed by the Norwegian mathematician Sophus Lie when he learned that Alfred Nobel’s plans for annual prizes would not include a prize in mathematics.
    • The laureates are selected by the Abel Committee, the members of which are appointed by the Norwegian Academy of Science and Letters.

    Has any Indian won this prestigious prize?

    • R. Srinivasa Varadhan, an Indian-American citizen won the Abel Prize in the year 2007 for his valuable contribution in “probability theory and in particular for creating a unified theory of large deviation”.

  • India ranks 136th in the World Happiness Report 2022

    India ranks 136th in the World Happiness Report 2022, while Finland becomes the happiest country for the fifth consecutive year.

    One can definitely question the credibility of such reports whenever India is being grouped with some African countries that too below Pakistan.

    World Happiness Report

    • The WHR is an annual publication of the UN Sustainable Development Solutions Network.
    • It measures three main well-being indicators: life evaluations, positive emotions, and negative emotions (described in the report as positive and negative affect).
    • Since 2011, the World Happiness Report (WHR) is released every year around the time of International Day of Happiness on March 20.
    • It was adopted by the UN General Assembly based on a resolution tabled by Bhutan.

    How is the WHI derived?

    • The ranking is done on a three-year average based on surveys of ‘Life Evaluation’ conducted by Gallup World Poll which surveys around 1000 people from each country to evaluate their current life on a scale of 0-10.
    • On this scale, 10 marks the best possible and 0 as the worst possible life.
    • Further, six key variables GDP per capita, social support, healthy life expectancy, freedom, generosity, and corruption contribute to explaining life evaluations.

    Top performers this year

    • The top five countries in the list are from Europe.
    • While the United States held the 16th spot in the happiest countries list.
    • Following Finland, Denmark bagged the second rank, while Iceland and Switzerland stood at third and fourth rank.
    • The Netherlands was at the fifth rank in the list.
    • Meanwhile, Luxembourg, Norway, Israel, and New Zealand were the remaining countries in the top 10.

    Dismal performers

    • Afghanistan held the last position of 146th in the list, with Lebanon (145th), Zimbabwe (144th), Rwanda (143rd), and Botswana (142nd) following.
    • Bangladesh has improved its ranking by seven notches on the WHI from 101 last year to 94 in 2022 out of 146 countries included in the report.

  • Who is a Chess Grandmaster?

    India’s teenage chess grandmaster Rameshbabu Praggnanandhaa has won praise for a stunning victory over world number one Magnus Carlsen in an online championship.

    Why are we reading this?

    • UPSC had asked three questions on sports in CSP 2021. They were based on Laureus World Sports Award, Summer Olympics, and ICC World Test Championship.
    • Try to ace uncertainties. No one can memorize such facts.

    Grandmaster: Behind the Title

    • Grandmaster is the highest title or ranking that a chess player can achieve.
    • The Grandmaster title — and other chess titles — is awarded by the International Chess Federation, FIDE (acronym for its French name Fédération Internationale des Échecs).
    • It is the Lausanne-Switzerland-based governing body of the international game.
    • The title is the badge of the game’s super elite, a recognition of the greatest chess talent on the planet, which has been tested and proven against a peer group of other similarly talented players.

    Other (lesser) titles

    Besides Grandmaster, the Qualification Commission of FIDE recognises and awards seven other titles:

    1. International Master (IM)
    2. FIDE Master (FM)
    3. Candidate Master (CM)
    4. Woman Grandmaster (WGM), Woman International Master (WIM), Woman FIDE Master (WFM), and Woman Candidate Master (WCM) and so on .

    Titles are for life

    • All the titles, including that of Grandmaster, are valid for life, unless a player is stripped of the title for a proven offence such as cheating.

    Qualifications for Grandmaster

    • The qualifications for Grandmaster were changed several times, including in 1957, 1965, and 1970.
    • Currently, FIDE awards chess’s highest honour to a player who is able to achieve a FIDE Classical or Standard rating of 2,500, plus three Grandmaster norms.
    • Grandmaster norms are defined by a set of complex and rigorous rules regarding tournaments, games, and players, that are set out in the FIDE Title Regulations.
    • The current regulations were approved by the FIDE Council on October 27, 2021, and came into effect on January 1, 2022.
    • Each norm is very difficult to attain.
    • Broadly, a player must have a performance rating of 2,600 or higher in a FIDE tournament that has nine rounds.

    Who holds maximum titles?

    • FIDE has so far recognized fewer than 2,000 Grandmasters out of the millions who play the game around the world.
    • A vast majority of Grandmasters have been male. Russia (and the erstwhile USSR) has produced the most Grandmasters in the world, followed by the United States and Germany.

    Grandmasters in India

    • India became a chess powerhouse in the 2000s, and now has more than 70 Grandmasters.
    • In 2016, Praggnanandhaa had become the world’s youngest IM at age 10 years, 10 months, and 19 days.

    Try this question from CSP 2021:

    Q. Consider the following statements in respect of the Laureus World Sports Award which was instituted in the year 2000:

    1. American golfer Tiger Woods was the first winner of this award.
    2. The award was received mostly by ‘Formula One’ players so far.
    3. Roger Federer received this award maximum number of times compared to others.

    Which of the above statements are correct?

    (a) 1 and 2 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

  • World Employment and Social Outlook – Trends, 2022

    Global unemployment is projected to stand at 207 million in 2022 (21 million more than in 2019 before the COVID-19 pandemic began) says ILO World Employment and Social Outlook – Trends 2022.

    World Employment and Social Outlook – Trends 2022

    • The report examines the impacts of the crisis on global and regional trends in employment, unemployment and labour force participation, as well as on job quality, informal employment and working poverty.
    • It also offers an extensive analysis of trends in temporary employment both before and during the COVID-19 crisis.

    Key highlights

    (1) Job Losses in 2022

    • It is estimated that in 2022 around 40 million people will no longer be participating in the global labour force.
    • The downgrade in the 2022 forecast reflects the impact of ever new variants of COVID-19 on the world of work.
    • Global working hours in 2022 will be almost two per cent below their pre-pandemic level.
    • This is equivalent to the loss of 52 million full-time jobs.

    (2) Pauperization

    • The pandemic has pushed millions of children into poverty.
    • It is estimated that in 2020, an additional 30 million adults fell into extreme poverty (living on less than $1.90 per day in purchasing power parity) while being out of paid work.
    • The number of extreme working poor — workers who do not earn enough through their work to keep themselves and their families above the poverty line — rose by eight million.

    (3) Impact on women

    • Women have been worse hit by the labour market crisis than men and this is likely to continue.
    • The closing of education and training institutions will have long-term implications for young people, particularly those without internet access.

    Key suggestions

    • There is the need for a broad-based labour market recovery — the recovery must be human-centred, inclusive, sustainable and resilient.
    • The recovery must be based on the principles of decent work — including health and safety, equity, social protection and social dialogue.

    Back2Basics: International Labour Organization (ILO)

    • The ILO is a UN agency whose mandate is to advance social and economic justice through setting international labour standards.
    • Founded in 1919 under the League of Nations, it is the first and oldest specialised agency of the UN.
    • The ILO has 187 member states: 186 out of 193 UN member states plus the Cook Islands.
    • The ILO’s international labour standards are broadly aimed at ensuring accessible, productive, and sustainable work worldwide in conditions of freedom, equity, security and dignity.

    Its Governing Body

    • The Governing body is the apex executive body of the ILO which decides policies, programmes, agenda, budget and elects the Director-General.
    • It meets three times a year, in March, June and November.

    Major reports released:

    1. World Employment and Social Outlook
    2. World Social Protection Report
    3. Global Wage Report

  • Places in news: Carmichael Mine in Australia

    The Adani Group will begin exporting high quality, low sulphur coal from its Carmichael mine in Australia as early as this week, tapping a new multi-decade source to meet energy needs.

    Carmichael Mine

    • The Carmichael mine is located in the North Galilee Basin, more than 300 kilometers from the Queensland coastline and approximately 160 km north-west of Clermont in regional Queensland.
    • The Carmichael project, proposed in 2010, had provoked a sustained campaign by climate activists in Australia and other places globally, forcing banks and insurers not to work with the Adani group.
    • The conglomerate run by India’s second-richest man Gautam Adani has planned an initial production of 10 million tonnes a year from the mines in the Galilee Basin.
    • The Coal mined here has low sulfur content and high calorific value.

  • Langtang Project: Nepal’s first hydropower from a glacial lake

     

    Langtang Microhydro Electricity Project, Nepal’s first hydropower from a glacial lake has become functional recently.

    Langtang Microhydro Electricity Project

    • The Project was built three years after the 2015 earthquake-avalanche that devastated the valley, with help from the Hong Kong-based Kadoorie Charitable Foundation.
    • It has a weir and spillway at the moraine, and the water is taken through a fibre glass-insulated penstock pipe to a powerhouse that generates 100kW of electricity.
    • It seeks to provide 24 hours of electricity to 120 households and tourist lodges in Kyanjin and Langtang.

    Uniqueness of the project

    • The project is the first-of-its-kind in Nepal to power a village and holds promise for other remote Himalayan valleys where the risk posed by expanding glacial lakes can be mitigated.
    • At the same time, it provides electricity to tourism-dependent families.

  • Economics Nobel for Natural Experiments

    The 2021 Nobel Prize in Economic Sciences was awarded to three US-based economists.

    Do you know?

    The Nobel Prize is officially called as Sveriges Riksbank Prize!

    Who are the awardees?

    • Nobel Committee awarded half the Prize to David Card for his “empirical contributions to labour economics”
    • Other half to Guido Imbens and Joshua Angrist “for their methodological contributions to the analysis of causal relationships”

    What makes this year’s award special?

    • This is the first time the economic prize has been divided in this fashion with one half going to one awardee and other half divided across two awardees.
    • In the past, prize money was divided equally between the awardees even if the prize was for different topics as is the case this time around.
    • It may appear that the Nobel Prize has been given for two different contributions, but there is a common theme: “natural experiments.”

    What are Natural Experiments?

    • Economists are often interested in causal questions such as the impact of education on incomes, impact of COVID-19 on poverty and so on.
    • They are also interested is understanding the direction of causality.
    • Economists have used two kinds of experiments to study these causality and direction of causality questions: random experiments and natural experiments.

    (I) Random experiments

    • Under randomized experiments, the researchers allocate say medicines to a treatment group and compare the effect of the medicine with the control group which is not given the medicine.
    • In 2019, the Nobel Committee gave awards to three scholars for their contribution to the field of randomized experiments.
    • However, one cannot randomize experiments to study issues such as why certain people and regions are more unequal or have fewer educational opportunities and so on.

    (II) Natural experiments

    • In natural experiments, economists study a policy change or a historical event and try to determine the cause and effect relationship to explain these developments.
    • The trio used such natural experiments to make some landmark contributions to economic development.
    • Natural experiments are more difficult for two reasons. The first is to identify what will serve as a natural experiment.
    • Second, in a random experiment, the researcher knows and controls the treatment and control groups which allows them to study the cause and effect of medicine.
    • But in natural experiments, such clear differentiation is not possible because people choose their groups on their own and even move between the two groups.
    • Despite the limitations, the researchers could use the natural setting to answer some big policy questions.

    Natural experiments conducted by David Card

    • One question of interest for policymakers is to understand the impact of higher minimum wages on employment.
    • Earlier studies showed that increasing minimum wages leads to lower unemployment.
    • Economists were also not sure of the direction of causation between minimum wages and employment.
    • Say a slowdown in the economy leads to higher unemployment amid lower income groups.
    • This could lead to lower income groups demanding higher minimum wages. In such a case, it is higher unemployment which leads higher minimum wages.

    Contribution of Angrist and Imbens

    • Angrist and Imbens showed how natural experiments can be used to identify cause and effect precisely.
    • We have discussed above how natural experiments make it difficult to separate control and treatment groups. This makes it difficult to establish causal relations.
    • In the 1990s, the duo developed a methodology – Local Average Treatment Effect (or LATE) – which uses a two-step process to help grapple with these problems of natural experiments.
    • Say, one is interested in finding the impact of an additional year of schooling on the incomes of people.
    • By using the LATE approach, they showed that effect on income of an additional year of education is around 9%.
    • While it may not be possible to determine individuals in the group, one can estimate the size of the impact.

    What is the importance of the award today?

    • Earlier it was difficult to identify natural experiments and even if one identified them, it was difficult to generate data from these experiments.
    • With increased digitalization and dissemination of archival records, it has not just become easier to identify natural experiments but also get data.
    • Economists have been using natural experiments to help us understand the impact of past policies.
    • As the 2020 pandemic struck, economists used the natural experiments approach extensively to analyse how previous pandemics impacted different regions and tried to draw policy lessons.

    India context

    • The methodology date back to the early and mid-90s and they have already had a tremendous influence on the research undertaken in several developing countries such as India.
    • For instance, in India, too, it is commonly held that higher minimum wages will be counterproductive for workers.
    • It is noteworthy that last year, in the wake of the Covid-induced lockdowns, several states, including UP, had summarily suspended several labour laws.
    • This included the ones regulating minimum wages, arguing that such a move will boost employment.
    • The main learning is that minimum wages can be increased in India without worrying about reducing employment.

  • The Atlantic Niño’s role in India’s erratic monsoon

    Context

    Last month, farmers from Madhya Pradesh threatened to take IMD to court for the inaccurate monsoon forecast this year. A question was also raised in Parliament about whether the Arctic warming had led to an erratic monsoon this year.

    Understanding the role of Atlantic Niño in monsoon prediction

    • Monsoon predictions are a monumental challenge, especially when it comes to the spatial distribution and the northward migration of the monsoon trough.
    • Forecast models tend to rely heavily on El Niño for monsoon predictions.
    • But only about 50 per cent of the dry years are explained by El Niño.
    • Clearly, Atlantic Niño is a significant player in monsoon evolution and models and forecasters must pay attention to this Atlantic teleconnection.
    • Atlantic Niño is El Niño’s little cousin in the Atlantic, also known as the Atlantic Zonal Mode.
    • Indian scientists from INCOIS have argued that the Atlantic Niño is in fact predictable up to three months in advance.
    • Every few years, from June to August, there is a warming in the eastern equatorial Atlantic, which does not get as much attention as its big brother El Niño.
    • The biggest rainfall deficits from the Atlantic Niño tend to occur over the Western Ghats and the core monsoon zone.

    How Atlantic Niño plays a role if Indian and Atlantic Oceans are not connected?

    • The Atlantic and Indian Oceans are not directly connected in the tropics via the ocean.
    • The Atlantic Niño affects the monsoon by producing atmospheric waves, which propagate into the Indian Ocean.
    • These waves affect air temperatures over the Indian Ocean and influence the land-ocean thermal contrast as well as Low Pressure Systems (LPS).

    Way forward

    • Overall, monsoon prediction skill has gone up in the IMD but even a 70 per cent accuracy means the forecasts will be wrong 30 per cent of the time.
    • Many of the Atlantic Niños occur during non-El Niño years and this offers a window of opportunity to increase forecast skills based on the accurate prediction of the Atlantic Niño.

    Conclusion

    No forecasts will ever be 100 per cent accurate. Climate scientists are also aware of the monsoon prediction challenge and they will continue to try to improve monsoon forecasts.

    Back2Basics:  El Niño and La Niña

    • These periodic weather patterns occur as a result of fluctuating ocean temperatures in one part of the world, namely the east-central equatorial Pacific Ocean.
    • This can lead to extreme weather.
    • When warm water builds up along the central and eastern tropical Pacific Ocean, an El Niño occurs.
    • Conversely, when cool water builds up along the same region, a La Niña occurs with the opposite impact.

  • What is Vishnuonyx?

    Between 12.5 million and 14 million years ago, members of a genus of otters called Vishnuonyx lived in the major rivers of southern Asia.

    Vishnuonyx neptuni

    • Vishnuonyx were mid-sized predators that weighed, on average, 10-15 kg.
    • Before this, the genus was known only in Asia and Africa (recent findings show that Vishnuonyx reached East Africa about 12 million years ago, according to the release).
    • Vishnuonyx depended on water and could not travel long distances over land.

    Why in news?

    • German researchers have discovered the fossil of a previously unknown species, which they have named Vishnuonyx neptuni, meaning ‘Neptune’s Vishnu’.
    • Fossils of these now extinct otters were first discovered in sediments found in the foothills of the Himalayas.
    • Now, a newly found fossil indicates it had travelled as far as Germany. ‘
    • The dispersal of Vishnuonyx otters from the Indian subcontinent to Africa and Europe about 13 million years ago. ‘
    • This is the first discovery of any member of the Vishnuonyx genus in Europe; it is also its most northern and western record till date.

    How did it travel as far as Europe?

    • According to the researchers, its travels over 6,000 km were probably made possible by the geography of 12 million years ago, when the Alps were recently formed.
    • These Alps and the Iranian Elbrus Mountains were separated by a large ocean basin, which would have made it easier for the otters to cross it.
    • Researchers believe ‘Neptune’s Vishnu’ first reached southern Germany, followed by Ancient Guenz and eventually, the Hammerschmiede.
