165th Anniversary of Charles Darwin’s Monumental Publication : On the Origin of Species.






This day, 24th November 2024, we commemorate the 165th anniversary of Charles Darwin’s monumental publication, On the Origin of Species, which was published on 24 April, 1859, based on his ground breaking research following a five year expedition on board the HMS Beagle five year voyage between 1831 to 36, the experience and findings of which Darwin used to publish his book under the title On the Origin of Species. Darwin was fifty when he published his findings. Darwin was precocious child with an extraordinary interest for reading and desire for exploration. He briefly studied medicine and then theology, before charting a path for himself to be as a geologist, naturalist and a scientist par excellence whose findings on the origin of species by natural selection has etched his name eternally in history. 

 Charles Darwin was born on 12 February 1809 in Shrewsbury, England. His interest in exploration motivated him to take up a challenging job as an unpaid naturalist on a science expedition on board the HMS Beagle. To his luck, the Beagle expedition was headed by captain, Robert FitzRoy, who wanted an enthusiastic and well-trained gentleman naturalist to join him on the Beagle’s second surveying expedition. Incidentally, Captain FritzRoy, had just completed a brief voyage on HMS Beagle and was back.

 HNS Beagle was commissioned to serve as a survey ship that was tasked ‘to survey Magellan’s Streights’. It took to the seas in May 1826 until returning back to the base on October 1830. Unfortunately, the Ships original Captain who had set sail in 1826, died by suicide on the seas in 1828 and therefore a new Captain of the Ship, Captain Robert FitzRoy, was appointed to command the ship, which was left headless. Notwithstanding the death of the commander of the Ship, the voyage and the survey continued under the command of its new captain until returning back to the base in 1830. 

 The success of the first edition of exploration by HNS Beagle helped it to undertake even more serious and challenging task, with necessary refitting of the ship. In 1831 HNS Beagle set sail on its most famous voyage to survey the South American coast and the Galapagos Islands. This expedition was to last for five years before returning back to England via New Zealand in 1836. It was on this voyage that Darwin set foot on the voyage as a young naturalist who would work under the command of Captain of the Ship FitzRoy.

 Captain FitzRoy, assigned the task of exploring the inland to his young naturalist, Darwin, so that this could help in understanding the geological changes that had happened over millennia. It helped Darwin to explore the Islands, even as the Beagle continued to survey the coasts. Darwin used this opportunity to study various plants and animals, collecting specimens for further analysis. In South America, Darwin found fossils of extinct animals that were similar to modern species. It was on the Galapagos Island that Darwin observed many variations of plants and animals that were similar to those he found in South America, suggesting that species adapted over time and to their environment. He collected plants, animals, and fossils, taking diligent field notes on many of his observations. His examination of finches on the Galápagos Islands (off the coast of Ecuador) led him to develop his ideas on evolution by natural selection.

 This experience and his findings and collection of samples and his own well documented drawings in his note books would later help him in the development of his theory of evolution by natural selection, which he finally published in 1859 as a book under the titled “On the Origin of Species”. His findings helped in the understanding of evolution and how species evolve over long period of time, which he later described as natural selection in his revised edition of the book published under the title “ On the Origin of Species by Natural Selection. Incidentally, in the Hall of Evolution, an exhibition at the Nehru Science Centre, Mumbai, there is a large exhibit with the scaled down replica model of HNS Beagle and a virtual book of Darwin, whose pages can be flipped by the visitor. There are also models of the finches of the birds which the visitor can feel and so also the drawings and sketches of Darwin from his nite books. This gallery was developed in 2016, when I served as the Director of this centre. 

 Darwin’s works reshaped our understanding of the diversity of life on Earth. However, within the brilliance of Darwin's ideas, a notable controversy emerged on his erroneous assumption of blended inheritance, which was later proved to be a blunder in the journey of evolutionary biology. The key contributions of Darwin’s book included his thesis which proposed the concept of natural selection as the driving force behind the gradual change in species over time. This laid the groundwork for the theory of evolution, challenging prevailing beliefs about the fixity of species. Darwin’s book explains how species evolve through the differential survival and reproduction of individuals with advantageous traits, leading to the adaptation of populations to their environments. Darwin presented compelling evidence from the fossil records and biogeography, supporting his theory by demonstrating the gradual changes in species over geological time and the distribution of species across different regions.

 "On the Origin of Species" sparked intense debates, not only within the scientific community but also in wider society. It influenced fields beyond biology, including philosophy, theology, and ethics, challenging prevailing worldview. 

 While Darwin's contributions to evolutionary theory are monumental, his assumption of blended inheritance reflects the limitations of scientific knowledge in his time. Darwin's assumption of blended inheritance was a logical extension of the scientific understanding of heredity in the mid-19th century. However, subsequent advancements in genetics, particularly the works of Gregor Mendel - which Darwin did not have an opportunity to read and understand - revealed the flaw in the assumptions of Darwin. The scientific logic behind genetic inheritance was first discovered by Gregor Mendel in the 1850s before the publication of the works of Darwin. Mendel experimented on pea plants and recorded how traits get passed down from generation to generation. He noticed that offspring weren’t simply a “blend” of their two parents, as falsely assumed by Darwin. 

 Darwin's failure or oversight in assuming blended inheritance does not diminish the overall significance of his work. It underscores the reality that failures are an integral part of everyone's lives including Darwin and this must be strongly communicated to our youngsters. Darwin's "On the Origin of Species" remains a foundational text in evolutionary biology, challenging and reshaping our understanding of life's diversity. While one can now say in hindsight that Darwin failed by falsely assuming blended inheritance, however, his mistake must serve as a reminder that failures are an integral part of our lives and we must teach our youngsters that failures are inevitable and that we only need course corrections as we move on with life and not be afraid of such failures. 

 Charles Darwin was not the first to propose a theory of evolution but his work had a great impact on society at the time. While other thinkers used his research to support their various (often opposing) views and ideas, Darwin avoided talking about the theological and sociological aspects of his work. He continued to write on botany, geology and zoology until his death on 19 April 1882. He is buried in Westminster Abbey, London.

TMM 2025 Fund Raising Target : Recollections of a Nostalgic Memory.

 



This post is courtesy of an Instagram post by the United Way Mumbai under the caption “Meet our Change Runners and Young Leaders” for the Tata Mumbai Marathon (TMM 2025), under which yours truly has also been featured. Although I have an Instagram account, I don’t use it but then this post by United Way Mumbai, which was shared with me by Ajay Mehta, a Trustee of Adhar, an NGO which I am supporting under the aegis of TMM 2025, has tempted me not only to revive my Instagram post but also to pen this article, whose caption may appear rather confusing.

The Instagram post, while coming as a pleasant surprise, also came in with a challenge, which perhaps was an ‘incentive’ - government type - for achieving a target of Rs 5 Lacs ( Five hundred thousand) that was set for me to raise, through crowdfunding, for Adhar, using the platform of TMM 2025. Adhar (An Association of Parents of Mentally Challenged Adults) an NGO that is working in a rather difficult area of addressing the challenges that parents and guardians of mentally challenged adults face. One of the main worries for these parents is a question that haunts them all - what happens to their special children after their demise? This question struck a chord with the visionary founder of Adhar (www.adhar.org) late Shri Madhav Rao Gore, who founded Adhar with a mission to take lifetime care of such special adults even after their parents and guardians breathe their last.  Passing through trials and tribulations Adhar has now established itself as a leading institute in providing lifetime care for special adults and has developed and is operating three Adhar units in Badlapur, Nashik, and Satara, Maharashtra, which take care of 350 plus special children, including 70 plus women, who require lifetime support and care. Adhar will need a separate write-up to describe their noble work, therefore, I am confining this post to the title of my article.

After reaching the target of Rs Five Lacs, assigned to me by one of the go-getter Trustees of Adhar who spearheads Adhar participation in TMM 2025, I thought I could relax in the glory of meeting my target. But then – surprise, surprise! – just as I crossed the finish line – the target of Rs 5 Lacs -, my target was doubled to Rs. 10 Lacs! The reward for success is… well, more target! A mantra that most successful senior government officials follow. This twist in the upward revision of the target as a reward for achieving one’s target brought back memories of my early days as Director at the National Science Centre, Delhi, where a similar situation had unfolded much to my annoyance and argument with my bosses, at a cost of course.

 In the middle of March 2007, I assumed the charge of Director of the National Science Centre, Delhi (NSCD). In one of those meetings of the heads of science centres, which decide the targets for science museums and centres, the then DG of NCSM, which governs all science centres and museums that function under the Ministry of Culture, Government of India, assigned visitor and revenue targets for each of the heads of the four zones, under which the NCSM science centres function. As the Director of the NSCD, my responsibility was the three science centres in the north zone – NSCD, RSC Lucknow, and KPSC Kurukshetra. I was assigned a visitor target of 2 Lac visitors for the year 2007-08 for NSCD. Although during the preceding couple of years, the visitors to NSCD had hovered around 1.4 to 1.6 Lacs, I did accept the target. Fuelled by an unending enthusiasm, I rallied my team, setting an ambitious internal target of 3 Lacs. We pulled together and brainstormed and evolved ideas and strategies that could help us reach this stiff target of 3 Lac visitors to NSCD, a target which was almost 50% higher than the highest ever achieved by NSCD, barring when the Dinosaur Alive Exhibition was presented. We had a series of follow-up meetings to monitor our set goals, and by December 2007, my team achieved a visitor figure of 3 Lacs, and we still had another three months to go before the financial year 2007-08 ended. My team, who spearheaded this initiative for which I was incidental as the head of the institute, did not rest and kept the momentum and when the financial year ended on 31st March 2008, they had clocked an impressive 4,26,000 visitors, with a 50% revenue increase to boot! Here comes the twist to the tale.

During a meeting of heads of science museums to fix the targets for the next financial year (2008-09), the then DG, rather than going by established norms to increase the target by 10% of the previous year's target, strangely and much to my annoyance and heated argument used a yardstick completely unscientific to assign target for NSCD, which was an increase of 10% on our extraordinary achievement for previous year which was more than 100% of our assigned target. The target assigned was 4.70 Lacs. All my pleas and heated arguments had gone in vain while assigning a target for NSCD.

Now, here is another extraordinary twist to the tale: Another national-level museum, the Birla Industrial and Technological Museum (BITM), Kolkata, a much older museum, which too was assigned a target of 2 Lac visitors for the financial year 2007-08, had ended up achieving a paltry 1.30 Lacs visitors when the year ended. Since NSCD was assigned 4.70 Lacs visitors and a corresponding revenue for the year 2008-09, I expected that a similar target would be given to BITM, which too was headed by a new Director, my contemporary. But then, the adage “all are equal some are more equal” kicked in, and the DG based on his so-called discussion with the Director, BITM assigned a 1.7 Lac visitor target to BITM, and lo and behold, justified it by stating that he had increased the target by 20% over what BITM had achieved.

Notwithstanding the fact that any discussion on this matter with the DG, even with rational thoughts, would only result in vituperative arguments and perhaps would also adversely impact my career prospects, I could not hold back. At the end of the heated argument with the DG, I ended my argument by saying his decision has only disincentivized NSCD and its extraordinary achievement of more than doubling its target and incentivized BITM, Kolkata the unit which had fallen much short of the assigned target. It is another matter that all my arguments fell on deaf ears and perhaps may also have had an impact on my career.

The TMM 2025 target of Rs 10 Lacs has brought back those old memories, which I thought would be an interesting read for my friends. Interestingly, most senior officers in the government work with the same principle and assign more work and higher targets for those who work sincerely to achieve their targets and the ones who don’t, remain untouched, rather incentivized, which it was in our case.

This case is not unique or specific to NCSM, I am sure this cuts across government institutions. One can witness people who are problem creators are never targeted, and mostly kept at arm’s length, and no coercive action or otherwise taken against them, while those who work sincerely are rewarded with more work with no incentives to motivate them. It is this quagmire that, unfortunately, breeds inefficiency in government and no one wants to dive deep into solving this problem. Although things have improved, an introspection will reveal there is a lot that needs to improve. There is an unwritten belief that the more one works there is that much more chance of going wrong and even if one comes out successful with ten and fails in one, the concerned will have to answer for that one failure, while in another case if an officer has achieved nothing, but the fact that nothing wrong has happened will get him scot-free. It is time for these changes and those who achieve must be incentivized and those who don’t must be disincentivized. Will this happen? A million-dollar question for sure.

Be that as it may, let me also take this opportunity to once again appeal to you all to please help me achieve the revised fundraising target of Rs 10 Lacs for TMM 2025 for Adhar by your kind donation using the link below.

The Tango of Science (Brownian Motion) and Art (Virar Fast - Art Installation of Valay Shinde): A Personal Experience Working with Science and Art Museums.

 








After my retirement from service as the Director of Nehru Science Centre, Mumbai after a brief stint in Delhi and a break, I joined the CSMVS, Mumbai, as an Advisor. Contrasting experience of working with the science museums for 35 years and now - for nearly three years - with the CSMVS has been quite enriching and educative. It is this tango of science and art that has come my way and motivated me to pen this article, differently!

One of the many new exhibitions that the CSMVS has completed and thrown open to the public is the Mumbai Gallery, which was opened on 14 October 2024. This gallery is dedicated to the city of Mumbai. It features historical artefacts that narrate the story of the people of Mumbai who have made this city the economic capital of India and a cosmopolitan city, which is also a dream city and a city of opportunity, for those who wish to dream. One of the significant artefacts in the Mumbai gallery is the “Virar Fast” art installation created by Valay Shende, which is prominently displayed at the entrance to the Mumbai gallery.

Mumbai, a cosmopolitan city of hope and aspiration for millions is majorly dependent on the suburban electric local rail transport for commute. The Mumbai Suburban Rail (Central, Western, and Harbour line) on an average commute 7.24 million commuters daily and is inextricably linked to most Mumbaikars, for whom Rail is their lifeline. The crowded suburban trains in Mumbai are sites that Mumbaikars experience daily. Virar Fast local during peak hours, quintessentially represents this scene. This daily phenomenon, experienced by Mumbaikars has motivated artist Valay Shende to craft his beautiful art installation “Virar Fast” which now finds a pride of place in the Mumbai gallery at the CSMSV Museum. This installation, no wonder made it prominently to the headlines in the Times of India, which covered the Mumbai gallery. The concept note provided by the artist for his work “Virar Fast’ describes his work of art as a representation of the “essence of relentless battle faced by the working class in their daily grind (travel)”.

The EMU (Electric Multiple Unit) that is used to run the Mumbai suburban trains is a household name in Mumbai. Mumbai electric rail transport began almost a century ago, on February 3, 1925, when the Great Indian Peninsular Railway (GIPR) introduced the first electric run trains that ran between Bombay VT (now CSMT) and Kurla Harbour. Incidentally one of these earliest electric engines that ran the trains in Mumbai (Bombay then) is in the collections of the Nehru Science Centre, Mumbai, and this pride collection was restored to its pristine beauty during the COVID pandemic period.

The heading for this article - “The Tango of Science and Art” - comes from my experience from one of those typically crowded peak time travel days in the Virar Fast local (Western Railways) that I used for commuting to Church Gate from Andheri. Most rail commuters by the Virar Fast local, during the peak hours, are confronted with the challenge of searching for foot space in a train that does not even have an additional square inch of space left. Although it is a usual occurrence for daily commuters, however, for me who uses the Virar Fast rarely, something profound struck me while travelling in this crowded local. As I stood, barely able to move amidst the sea of passengers on the Virar Fast local - which I had boarded at Andheri for travelling to Church Gate - the familiar jostling, swaying, and chaotic shuffle of bodies, its indescribable odour, the sound, and noise, which I was experiencing, reminded me of something unexpectedly scientific: the Brownian motion.

For over 35 years, I worked with science museums, dedicated to science communication, immersed in the language of molecules, atoms, and scientific phenomena through my work with science museums across India. Creating exhibits to explain the microscopic world of science to the uninitiated visitor in science, almost always, makes a science museum curator rely on analogies. Brownian motion is one such scientific phenomenon, which was one of the first exhibits that I had developed as a young curator way back in 1988. I vividly remember having used a mechanical analogy to explain the complicated motions of molecules that constitute the Brownian motion. Post my retirement, I found myself stepping into a different realm - an art museum, the CSMVS Museum in Mumbai. At first, this transition was like moving to an entirely different universe. CP Snow’s essay on “The Two Cultures”—the stark divide between the world of sciences and that of the arts—suddenly made perfect sense to me. I felt the chasm between the analytical, data-driven logic of science and the subjective, emotional world of arts and literature. Yet, as the months passed, I began to realize that perhaps these two worlds weren't as distinct as they first appeared. Slowly, I started seeing how creativity was the common thread weaving them together, regardless of their different forms of expression or understanding.

But it wasn’t until that epiphanic moment in the Virar Fast Local train—a crowded, bustling, Mumbai local—that everything truly crystallized for me. The human movement in that compartment was not unlike the random motion of particles in Brownian motion, which Einstein predicted. In this seemingly chaotic environment, every jolt, every push, every nudge appeared to be dictated by some kind of an invisible force: the crowdedness of the train, the positioning of passengers, and their collective aim to reach their workplace – destination, in time. That instant of epiphany helped me see some kind of a parallel between the everyday scene of Mumbai peak time local travels and the microscopic world of science, Brownian motion.

Just like molecules in a substance, the crowd in the Virar Fast Local was densely packed, with passengers barely moving, constrained by those around them, pushing and shoving each other. This reminded me of how molecules in a solid vibrate but are confined to fixed positions, unable to move freely. As the density of the crowd decreased slightly at each station – with people alighting, it felt akin to the molecular behaviour in a liquid state—where the passengers (like molecules) could now flow past each other, with more freedom of movement, though still closely bound by the space limitations. Finally, as the train neared Churchgate, passing through intermittent stations at Bandra, Dadar, Mumbai Central, Grant Road, Churni Road, and Marine Line where more and more people alighted, few boarded, the compartment felt almost gaseous as it passed Charni Road, with passengers dispersed, with an ability to move freely and randomly in any direction, unlike what they could do earlier at Andheri, or Bandra and to some extent at Dadar. This experience helped me understand the Brownian motion as a fascinating and relatable way to conceptualize the movement of particles in different states of matter, described below

Solids and Packed Crowds: In peak hours, when the train is densely packed, people have minimal space to move, much like particles in a solid. Here, movement is constrained, and individuals can only shift slightly, often bouncing off each other within the confined space—analogous to the restricted vibrational motion of particles in a solid.

Liquids and Moderate Crowding: As more passengers alight at Bandra, Dadar, and Mumbai Central, and few board, there’s a slight increase in movement of people. The density of commuters is lower than in the packed train, providing a bit more freedom for the commuters to navigate within the coach. This state is comparable to the behaviour of particles in a liquid, where movement is still random but particles can flow past each other within a confined space.

Gases and Spacious Trains: As the train nears the destination (Church Gate) the number of passengers in the coach decreases, and people have ample space to move freely. This situation mirrors the random, high-energy movement of particles in a gas, where they occupy more space and move independently without frequent interactions.

The Virar Fast train ride became a living analogy for me—a vivid, real-life comparison to the randomized movement of particles in different states of matter. The random movements of people mirrored the Brownian motion described by Einstein in the Annus Mirabilis year, 1905, in one of his five acclaimed papers, which were published in that year. Although Brownian motion, had been observed before Albert Einstein’s time, what made Einstein’s 1905 paper "On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat," the third of his five papers written in May 1905, remarkable was that the paper provided a theoretical explanation and a mathematical framework for understanding the motion of the particles in the fluid. His paper was one of the five revolutionary papers in Einstein's annus mirabilis (1905). The Brownian Motion - the random movement of particles in fluids - was already identified by physicists before Einstein. However, Einstein used the knowledge of this phenomenon to prove the existence of atoms, through his paper.

My personal experience of the movement of passengers in the Virar Fast Local and the clarity it provided for the Brownian motion, wasn’t just about physics or the scientific explanation of the movement of molecules in fluid. It made me realize how science and art—two seemingly separate worlds—intersect in ways I hadn’t previously considered. The Virar Fast Local art installation of Valay Shinde, displayed in the Mumbai Gallery, perhaps, helped me look at the experience of Mumbai local travel differently. Art, with its focus on the human experience and creativity, can be found in the very randomness of the movement in that train. Science, with its focus on understanding phenomena, finds itself expressed in the chaotic yet measurable motions of people.

As someone who has spent years working in a science museum including a few years heading an art institution – NGMA Mumbai, and now working at the CSMVS, I now fully appreciate the delicate balance between the world of science and arts, two worlds. They are intertwined more intricately than CP Snow’s "Two Cultures" would suggest. Art and science, both expressions of human creativity, aren’t just complementary—they are essential to one another. My experience in science helped me understand the structure and patterns of the physical world, while my exposure to art at the CSMVS Museum opened my eyes to the beauty and meaning that lie within those structures.

Today, as I stand at the crossroads of science and arts, I see the power of interdisciplinary understanding. My epiphany on the crowded Mumbai local has given me a profound appreciation for how science and art come together, just as the motion of particles can be beautifully reflected in the movement of people in the everyday chaos of life. Through this lens, I can see how the randomness of life—whether in a crowded train or a scientific phenomenon—holds both scientific explanation and artistic beauty, as articulated by Valay Shinde in his art installation. And in that realization, I feel more connected to both fields than ever before.

Long live Sciences and Arts and their practitioners and may they come closer than ever before.

As someone who has spent years working in a science museum including a few years heading an art institution – NGMA Mumbai, and now working at the CSMVS, I now fully appreciate the delicate balance between the world of science and arts, two worlds. They are intertwined more intricately than CP Snow’s "Two Cultures" would suggest. Art and science, both expressions of human creativity, aren’t just complementary—they are essential to one another. My experience in science helped me understand the structure and patterns of the physical world, while my exposure to art at the CSMVS Museum opened my eyes to the beauty and meaning that lie within those structures.

Today, as I stand at the crossroads of science and arts, I see the power of interdisciplinary understanding. My epiphany on the crowded Mumbai local has given me a profound appreciation for how science and art come together, just as the motion of particles can be beautifully reflected in the movement of people in the everyday chaos of life. Through this lens, I can see how the randomness of life—whether in a crowded train or a scientific phenomenon—holds both scientific explanation and artistic beauty, as articulated by Valay Shinde in his art installation. And in that realization, I feel more connected to both fields than ever before.

Long live Sciences and Arts and their practitioners and may they come closer than ever before.edia
