Harvest Season

This is thanksgiving week in many parts of India. A week of festivals marked with celebration and gratitude for nature’s bounty that feeds and sustains us. With the winter season drawing to a close, it is time to reap the harvest of the long months of labour and prayers. Lohri in north India, Pongal in south India, Makar Sankranti in the west, and Magh Bihu in the northeast of the country celebrate the harvest with joy, festivities, and food.

Interestingly, in many other parts of the world, it is autumn, before the winter sets in, that is the season of harvests.  In America Thanksgiving weekend is marked by families joining hands in gratitude over sumptuous meals; in Japan generations of poets and painters have tried to capture the spirit of the annual cycle of seasons in Haikus and brush strokes. Other parts of the world have their traditional ways of marking the cycle of sowing and reaping. Increasingly, as more of the world’s population moves from direct links with the soil to urban life, we seem to revel more in the food and festivities related to these festivals, often forgetting these very elements of nature—sunlight, air, water and soil–that make all life possible.

This week also marks the start of a new calendar year, and the start of the period when the sun begins its northward journey. A good time to give thanks for what has made all this possible, and a reminder to value and cherish every new morning.

This poem by Mary Oliver captures the sentiment beautifully.

 Why I Wake Early

Hello, sun in my face.
Hello, you who make the morning
and spread it over the fields
and into the faces of the tulips
and the nodding morning glories,
and into the windows of, even, the
miserable and the crotchety –

best preacher that ever was,
dear star, that just happens
to be where you are in the universe
to keep us from ever-darkness
to ease us with warm touching,
to hold us in the great hands of light –
good morning, good morning, good morning.

Watch, now, how I start the day
in happiness, in kindness.

Mary Oliver was an acclaimed and award-winning American poet whose work reflects a deep communion with the natural world in an age of excesses of modern civilization. She died, almost exactly a year ago, on 17 January 2019, at the age of 83.


A Traffic Jam of Nobel Laureates

Harvard is on top of the pile of institutions when it comes to Nobel Laureates, with 56 currently on the faculty and 160 being associated with the University at some stage of their careers, either as students or faculty. Cambridge University comes second, with 120 Laureates being associated with it; University of California at Berkeley third with 107, followed by University of Chicago at fourth place with a round 100.

I imagine that at any of these places, the probability of bumping into a Nobel would be quite finite.

However, such a possibility is pretty remote in any city or town of India. Until last week, at Bangalore ….

January 3 saw Prof Steven Hell address the Indian National Science Congress held in the city. Prof. Hell is one of the directors of the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany and received the Nobel Prize in Chemistry in 2014 ‘for the development of super-resolved fluorescence microscopy’. The next day saw Prof Ada Yonath address the same gathering. She is a protein crystallographer who was awarded the 2009 Nobel Prize for Chemistry. Both of them stressed the need for scientists to be open minded and for scientific research to be independent.

54E03126-F55D-4DF3-8810-88E1D954EA78January 4 was also the day when Profs Abhijit Banerji and Esther Duflo were in conversation with Manish Sabarwal at the Bangalore International Center, and demystified RCTs, or Randomized Control Trials, the body of work which got them their newly minted Nobels. RCTs are an experimental method to do research on developmental issues like education and poverty, to find what can really be effective to solve the problems, and hence can help policy making.

January 7 saw the 1998 Economics Nobel, Prof Amartya Sen in the city,  felicitating the winners of the prestigious Infosys Prize. Speaking at the event, Prof Sen said ‘There are deep links between friendship and knowledge. Our intellectual horizons expand when we learn from each other.’

January 15 will see Prof Venki Ramakrishnan, who shared the 2009 Chemistry Nobel with Prof Ada Yonath (above) and Prof Thomas Steitz for research on the ‘structure and function of the ribosome’ speak on Science and Society, once again at the Bangalore International Center.

It doesn’t rain, it pours!

Lucky Bangalore, to hear all these messages. And what a great unity in the underlying messages…the importance of evidence-based research, of the need for research to be independent and unbiased, the crying need to base policy on research, and the importance of cooperation and a barrierless world.





It’s the age of startups! Every day one hears of enterprising young 20-somethings making their first million with an innovative product or service that people today lap up with enthusiasm.

I recently read about a number of such ventures that are literally cashing in on sleep (or the lack thereof!) Online mattress brands! In these times when the millennials have too much stress, too little time, inability to get a good night’s sleep, but the ability to afford quick-fix solutions and products, there are smart operators who combine all this into successful commercial ventures. With inviting names like Wakefit, Wink and Nod, Sleepycat and Sunday Mattress, these offer “sleep solutions”. And attractive “offers” from free home delivery and installation, free trial and return, to “sleep internships”, and customised recommendations of the best fit based on an analysis of the customer’s age, height, weight and location!

ripImagine needing so much help to get a good night’s sleep! I have grown up in an age when mattresses had very different connotations. Mattresses were filled with cotton, and were usually of the same size and thickness. Often this cotton was carded by hand by itinerant carders who established camp at the house for a few days marked by the twang of their simple tools, and fluff-filled air. The cotton was filled in covers, stitched in with strong thread, and then beaten heartily with sticks to even out the lumps and bumps. All this done with dexterity and the long experience of a traditional occupation. With mechanisation, these occupations were replaced with neighbourhood shops where the same process was done by a simple machine. Now one took one’s old mattresses there to be opened and redone, with dire warnings that the cotton within was not to be mixed up with any other inferior variety!

This was an exercise carried out every few years. The annual exercise was the sunning of the mattresses. This was a traditional ritual, generally after the rainy season and before Diwali when the strong sun took away the dampness and made the cotton swell. The wonderful smell and feel of freshly-sunned mattresses was guaranteed to induce the cosiest slumber; without any ‘scientific’ testing to arrive at the perfect ergonomic formula.

Furthermore, in addition to supporting the large numbers of family members, most households had a stack of spare mattresses, and quilts. These were stored carefully; many traditional houses had a special space and arrangement for this. They were taken out when guests arrived, and when there were family gatherings like weddings. Over time, as families, and houses grew smaller, and people’s mobility increased, the stacks of mattresses decreased. Then the market began to offer ready-made mattresses, introducing other materials like foam and coir. It became easier to go to a shop and order the one best suited from the limited options available. The familiar childhood mattresses remained at the family home with the parents, to be slept on when visiting them. And as time moved on, and life got faster, the new breed of urban nomads had not the time nor space to go the shop to buy a mattress. Life became so stressed and so frenzied that sleep also became a sought-after commodity. And voila, the market was open for online sleep solutions!

I do appreciate the needs of the times, as well as admire the enterprise to meet the needs. But it also makes me grimace and smile! Belonging as I do to a generation of ‘home-made’ cotton mattresses, I have also inherited several of these. I try, in my own way, to follow some of the annual air-and-sun traditions. And I am grateful that I still get a good night’s sleep without any external help!



2020 is here!

vision chartWell, years come and go, so what is so special about 2020?

Nothing really, except that it is the start of a new decade. And 20/20 is symbolic—understood in common parlance to stand for perfect vision! 2020, a few decades ago, also stood for some far-away date, by which the world would be perfect–a happily ever after year. No particular reason for this, that I can see. Maybe simply because it was an easy-on-the-tongue alliterative year? Or maybe because of the pharmacological implication?

But what is 20/20 vision?

Actually, it denotes clarity of vision—visual acuity, to state it in slightly more ‘ophthalmological’ terms! To explain in layman terms, 20/20 is simply your ability to read a particular line on the eye chart from a distance of 20 feet. The size of the letters on one of the smaller lines near the bottom of the eye chart (or Snellen chart, after the Dutch doctor who developed this system in 1862) is standardized to correspond to “normal” visual acuity — this is the “20/20” line. If the letters on this line are the smallest you can identify, you have normal (20/20) visual acuity. The increasingly larger letter sizes on the lines on the Snellen chart above the 20/20 line correspond to worse visual acuity (20/40, 20/60, etc.). If you can read lines with smaller letters below the 20/20 line, then you have better than 20/20 vision (e.g., 20/15, 20/12, 20/10). The single big “E” at the top of the eye chart corresponds to 20/200 visual acuity. Legal blindness is when this is the smallest letter size someone can read even with corrective lenses.

Vision is more than visual acuity or eyesight. In addition to clarity of sight, “vision” is all interactions between the eyes and the brain, and all neurological processes that take place in the brain to make the sense of vision possible.

Here are some of things we envisioned would happen by 2020:

VISION 2020 was a global initiative that aimed to eliminate avoidable blindness by the year 2020. It was launched in 1999 by the World Health Organization along with over 20 other international non-governmental organisations, I am not sure how well it has succeeded. (https://www.who.int/blindness/partnerships/vision2020/en/)

Closer home, India’s Vision 2020 was a document prepared by the Technology Information, Forecasting and Assessment Council (TIFAC) of India’s Department of Science and Technology under the chairmanship of Dr. A. P. J. Abdul Kalam and a team of 500 experts, which set out a plan to change the country by 2020. In Dr. Kalam’s words the objective of the plan was “Transforming the nation into a developed country, ..based on India’s core competence, natural resources and talented manpower, for integrated action to double the growth rate of GDP and realize the Vision of Developed India”.

The reality is here for everyone to see—even those who don’t have 20/20 vision!

Well, be that it may, let us pray not only for 20/20 vision in 2020, but also that our reality is closer to our vision!

So that these are indeed visions, not dreams!








Happy 2020—To a Year of Peace, Prosperity and Plant Health!

farmerThe UN General Assembly has declared 2020 as the International year of Plant Health. The purpose of this is to ‘raise global awareness on how protecting plant health can help end hunger, reduce poverty, protect the environment, and boost economic development.’ (http://www.fao.org/plant-health-2020/en/)

Plants are the basis of all food chains—in that sense, all life on earth depends on plants for food. And as important—plants give us the oxygen we need to sustain life on earth. The role of plants and trees in regulating climate cannot be over-emphasized. So in very truth, plant health is fundamental to food security and environmental sustainability—the very basis of PEACE and PROSPERITY.

Yet, we don’t pay attention to keeping plants healthy. And that is why the UN has thought of declaring a special year for this.

As we step into the new year and are in the mood of making resolutions, here are a few related to plant health:

  • Ensure that the you minimize use of chemical pesticides and fertilizers in your gardens and lawns. This is essential for long-term health of soil and plants.
  • Avoid transporting plants and bio-products across borders while travelling, as these can become pests or lead to major pest attacks in alien ecosystems.
  • Grow local plants, and support locally grown and local vegetables, fruits and other produce.
  • Buy organically-grown produce.

And while we are on the subject, a tribute to one who worked in the area of plant health all his life.

Dr. HY Mohan Ram was one of India’s pre-eminent botanists. He taught Botany in Delhi University for over 40 years and guided over 35 doctoral students. He wrote textbooks, popularized science, was an eminent planner and science administrator. He recognized the importance of reaching out to young people in inculcating scientific temper. To quote: ‘A demanding but satisfying assignment taken up by me was as Chairman of the Committee for the preparation of biology textbooks for Classes XI and XII, sponsored by the NCERT.’ He mentions the goal of such an endeavour as inculcating in the student ‘a spirit of enquiry, creativity, objectivity, the courage to question, aesthetic sensibility and environmental awareness’. India owes him a huge debt–he was guru to generations of India’s botanists in one way or the other.

Another dedicated botanist-environmentalist is Seema Bhatt. And her message is for aspiring women field scientists: ‘I have often worked in situations where I have been the only woman—a fact that has never bothered me. I have never been made to feel any different. I mention this to emphasize the fact that being a woman should not deter anyone from choosing a career like this.’

May we make and keep many resolutions to contribute to a better world!
