Nobel Prize: Physics
Announced 6 October by the Royal Swedish Academy of Sciences
 |
Winner: Francis HalzenPrize share: 1/1
|
Awarded for
Halzen won for his key role in building the IceCube Neutrino Observatory and for the discovery of high-energy neutrinos that come from outer space.
First, what is a neutrino? It is a tiny particle with almost no mass and no electric charge. It passes through almost everything, including your body, without stopping. Billions of them pass through your hand every second and you feel nothing. High-energy neutrinos are created by some of the most violent events in the universe, far away from Earth.
Because they are so hard to stop, they are also very hard to catch. IceCube solves this with a simple idea. It uses a full cubic kilometre of clear ice deep under the South Pole, with light sensors buried inside it. When a neutrino hits an atom in the ice, it makes a faint flash of light. The sensors record that flash, and scientists can work out where the neutrino came from.
Why it matters
A normal telescope collects light, and light can be blocked or bent on its way to us. Neutrinos travel in straight lines and nothing blocks them. So they act like messengers that bring information straight from the most extreme places in space. The Nobel Committee said his work has opened the way to a new kind of astronomy.
Nobel Prize: Chemistry
Announced 7 October by the Royal Swedish Academy of Sciences

Winner: Henri B. KaganPrize share: 1/2
|
 |
Winner: Kenso SoaiPrize share: 1/2
|
Awarded for
Kagan and Soai won for discovering non-linear effects and autocatalysis in asymmetric organic synthesis. That sounds heavy, so let us break it down.
Many molecules come in two forms that are mirror images of each other, like your left hand and right hand. They look alike, but they do not fit the same way. Think of a left-handed glove. It will not fit your right hand. Chemists call this property chirality.
Here is the puzzle. Living things use only one of the two mirror forms. The amino acids that build the proteins in your body are almost all the ‘left-handed’ type. For over a hundred years, chemists asked how nature ended up choosing just one side. The Nobel Committee chair said the two winners provided a solution to this old mystery, showing how a one-sided mix can appear on its own.
Kagan found that in certain reactions, a small imbalance in the helper molecule (the catalyst) can create a much bigger imbalance in the final product. This is called a non-linear effect. Soai went further. In his reaction, the product helps to make more of itself, which is called autocatalysis. Even a tiny starting excess of one hand grows step by step until almost everything is of that one hand. Imagine a classroom where a few more students start turning left, and each new left-turner pushes others to turn left too. Soon almost everyone turns left.
Why it matters
Medicines often work only in one mirror form. The other form can be useless or even harmful. The reactions these two scientists developed help chemists make medicines in the correct form, which is why the committee said their work is decisive for drug manufacturing.
Nobel Prize: Physiology or Medicine
Announced 5 October by the Nobel Assembly at Karolinska Institutet
 |
Winner: Karl DeisserothPrize share: 1/3
|
 |
Winner: Peter HegemannPrize share: 1/3
|
 |
Winner: Georg NagelPrize share: 1/3
|
Awarded for
The three scientists won for discoveries about light-gated ion channels, which led to a method called optogenetics. They share the prize equally.
The story begins with a tiny single-celled alga called Chlamydomonas, which swims towards light. Hegemann and Nagel found out how it senses light. It has a protein, channelrhodopsin, that opens a small gate in the cell wall when blue light falls on it. In simple words, it is a gate that opens with light, like a door with a light sensor.
Deisseroth then took the gene for this protein and placed it into nerve cells. The cells began to react to light. Now scientists could switch chosen nerve cells on or off just by shining light, which is like using a light switch for one particular wire in a huge electric board.
Why it matters
The brain has billions of nerve cells, and earlier tools could not target single types of cells easily. With optogenetics, researchers can study how nerve cells shape memories, feelings and behaviour in a living brain. It is also being tested in clinical research, for example to restore sight in people with visual impairment. The Nobel Committee chair said it allows brain mapping that researchers could once only dream of.
Nobel Prize: Literature
Announced 8 October by the Swedish Academy
 |
Winner: Anne CarsonPrize share: 1/1
|
Awarded for
The Swedish Academy honoured her bold and inventive body of work, which talks in a playful way with the classical tradition and has created new forms for modern literature.
In simple words, Carson takes old Greek and Roman stories and ideas and brings them into today’s world. She does not stick to one form. Her books mix poetry, prose, essays, translation and even dramatic dialogue. Her first book, Eros the Bittersweet (1986), looks at the pleasure and pain of desire in ancient Greek writing. Her best known work, Autobiography of Red (1998), is a novel written in verse. It retells the myth of the monster Geryon, who is killed by Herakles, as a story about a young man with red wings and his love and loneliness. Another book, Nox, was written in memory of her brother Michael.
Why it matters
Her work shows that ancient stories are not dead. Retold with imagination, they can speak about love, grief and identity in a fresh way. She has also widened what a book can look like, which is the kind of new form the Academy praised.
Nobel Prize: Peace
Announced 9 October by the Norwegian Nobel Committee
 |
Winner: Navanethem ‘Navi’ PillayPrize share: 1/1
|
Awarded for
The Norwegian Nobel Committee honoured her for her efforts to promote peace and international law.
In simple words, she spent her life using the law to protect people. She faced racial discrimination herself, and she turned that experience into a career defending human rights. As a judge in the Rwanda tribunal, she helped hold people responsible for genocide. As UN human rights chief, she spoke up for dignity and equality across the world.
Why it matters
The Committee reminded the world that the rule of law, within countries and between countries, is what holds peace together. When disputes are settled in courts and not by force, conflicts can be solved without violence. In short, the message of this prize is that peace needs justice.
Nobel Prize: Economic Sciences
Announced 12 October by the Royal Swedish Academy of Sciences. Both winners are from the United States.
Officially called the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. It was not in Alfred Nobel’s original will. Sweden’s central bank set it up in 1968, and it was first given in 1969.

Winner: Robert E. HallPrize share: 1/2
|
 |
Winner: Michael WoodfordPrize share: 1/2
|
Awarded for
Hall and Woodford won for the microeconomic foundations of macroeconomic stabilisation. Let us make that simple.
An economy has good times and bad times, such as booms, recessions and sudden price rises. Governments and central banks try to keep the economy steady. This is called stabilisation. To do it well, they need good models, which are like maps of how the economy works.
The winners built these maps from the ground up. They started with how real people and firms make choices, and then showed how those choices add up to what happens in the whole economy. This made policy tools more reliable. Three ideas from their work are now used everywhere:
Sticky prices
Prices do not change immediately when demand changes. They adjust slowly. For example, a shop does not change its menu prices every day, even if costs go up.
Output gap
A measure of how far the economy is from its healthy, full-use level. The aim of policy is to push this gap towards zero.
Forward guidance
The central bank openly tells people what it is likely to do with interest rates in the future. This became very important after the 2008 financial crisis, when rates were already near zero.
Woodford also showed that central banks can steer the economy by setting interest rates, and not only by controlling the amount of money.
Why it matters
Central banks and finance ministries around the world use models based on this work. When you hear that a central bank has changed its policy rate or has signalled its future path, this is the kind of thinking behind it.

Steve Ovett, the famous British middle-distance athlete, won the 800-metres gold medal at the Moscow Olympics of 1980. Just a few days later, he was about to win a 5,000-metres race at London’s Crystal Palace. Known for his burst of acceleration on the home stretch, he had supreme confidence in his ability to out-sprint rivals. With the final 100 metres remaining,
[wptelegram-join-channel link=”https://t.me/s/upsctree” text=”Join @upsctree on Telegram”]Ovett waved to the crowd and raised a hand in triumph. But he had celebrated a bit too early. At the finishing line, Ireland’s John Treacy edged past Ovett. For those few moments, Ovett had lost his sense of reality and ignored the possibility of a negative event.
This analogy works well for the India story and our policy failures , including during the ongoing covid pandemic. While we have never been as well prepared or had significant successes in terms of growth stability as Ovett did in his illustrious running career, we tend to celebrate too early. Indeed, we have done so many times before.
It is as if we’re convinced that India is destined for greater heights, come what may, and so we never run through the finish line. Do we and our policymakers suffer from a collective optimism bias, which, as the Nobel Prize winner Daniel Kahneman once wrote, “may well be the most significant of the cognitive biases”? The optimism bias arises from mistaken beliefs which form expectations that are better than the reality. It makes us underestimate chances of a negative outcome and ignore warnings repeatedly.
The Indian economy had a dream run for five years from 2003-04 to 2007-08, with an average annual growth rate of around 9%. Many believed that India was on its way to clocking consistent double-digit growth and comparisons with China were rife. It was conveniently overlooked that this output expansion had come mainly came from a few sectors: automobiles, telecom and business services.
Indians were made to believe that we could sprint without high-quality education, healthcare, infrastructure or banking sectors, which form the backbone of any stable economy. The plan was to build them as we went along, but then in the euphoria of short-term success, it got lost.
India’s exports of goods grew from $20 billion in 1990-91 to over $310 billion in 2019-20. Looking at these absolute figures it would seem as if India has arrived on the world stage. However, India’s share of global trade has moved up only marginally. Even now, the country accounts for less than 2% of the world’s goods exports.
More importantly, hidden behind this performance was the role played by one sector that should have never made it to India’s list of exports—refined petroleum. The share of refined petroleum exports in India’s goods exports increased from 1.4% in 1996-97 to over 18% in 2011-12.
An import-intensive sector with low labour intensity, exports of refined petroleum zoomed because of the then policy regime of a retail price ceiling on petroleum products in the domestic market. While we have done well in the export of services, our share is still less than 4% of world exports.
India seemed to emerge from the 2008 global financial crisis relatively unscathed. But, a temporary demand push had played a role in the revival—the incomes of many households, both rural and urban, had shot up. Fiscal stimulus to the rural economy and implementation of the Sixth Pay Commission scales had led to the salaries of around 20% of organized-sector employees jumping up. We celebrated, but once again, neither did we resolve the crisis brewing elsewhere in India’s banking sector, nor did we improve our capacity for healthcare or quality education.
Employment saw little economy-wide growth in our boom years. Manufacturing jobs, if anything, shrank. But we continued to celebrate. Youth flocked to low-productivity service-sector jobs, such as those in hotels and restaurants, security and other services. The dependence on such jobs on one hand and high-skilled services on the other was bound to make Indian society more unequal.
And then, there is agriculture, an elephant in the room. If and when farm-sector reforms get implemented, celebrations would once again be premature. The vast majority of India’s farmers have small plots of land, and though these farms are at least as productive as larger ones, net absolute incomes from small plots can only be meagre.
A further rise in farm productivity and consequent increase in supply, if not matched by a demand rise, especially with access to export markets, would result in downward pressure on market prices for farm produce and a further decline in the net incomes of small farmers.
We should learn from what John Treacy did right. He didn’t give up, and pushed for the finish line like it was his only chance at winning. Treacy had years of long-distance practice. The same goes for our economy. A long grind is required to build up its base before we can win and celebrate. And Ovett did not blame anyone for his loss. We play the blame game. Everyone else, right from China and the US to ‘greedy corporates’, seems to be responsible for our failures.
We have lowered absolute poverty levels and had technology-based successes like Aadhaar and digital access to public services. But there are no short cuts to good quality and adequate healthcare and education services. We must remain optimistic but stay firmly away from the optimism bias.
In the end, it is not about how we start, but how we finish. The disastrous second wave of covid and our inability to manage it is a ghastly reminder of this fact.
