In this guest InterDialogue, folklorist and InterPlex content and operations strategist Rowan Glass converses with K. Brandon Barker, Associate Professor of Folklore at Indiana University Bloomington and editor of Children’s Folklore Review. Barker co-authored the book Folk Illusions with Claiborne Rice, introducing the term “folk illusions” to study children’s play forms in relation to the science of perception and cognition. He has also written on animal cognition and the folklore of science with comparative psychologist Daniel Povinelli, with whom he co-edited the book The Aesop’s Fable Paradigm. For several years, Barker led the Folklore and Science Section of the American Folklore Society, which he helped found. The conversation begins with two notoriously murky words: how to define both folklore and science when both terms carry so much baggage? Barker makes the case that “the folk” are far less naive than some scientists assume, and that folklore’s ethnographic methods can offer insights into problems like vaccine hesitancy and misinformation by taking seriously perspectives often overlooked by or inaccessible to scholars in other fields. Glass then addresses Barker’s research on folk illusions and what children’s play reveals about adultcentrism, body acquisition, and the science of perception. They probe the epistemological stakes of folklore scholarship in relation to the natural sciences, asking whether folklorists can or should advance universal claims and broad theoretical frameworks. They also talk about computation folklore and Barker’s work on the folklore of animal cognition. The conversation then turns toward humans’ seemingly inherent tendencies toward anthropomorphism and human exceptionalism—whether applied to animals or artificial intelligence. Barker asserts that our seemingly inherent penchant for projecting human qualities onto the non-human world might be more powerful, and perhaps more dangerous, than we realize.

Earth’s Memory, Part One Abstract Every rock carries a fragment of Earth’s memory. Collectively, these fragments preserve an extraordinary geological record spanning more than 4.5 billion years of planetary evolution. This article traces that record through the deep-time history of our planet—from the formation of Earth’s earliest crust and the Great Oxidation Event, when microbial life transformed the planet’s atmosphere, to the five great mass extinctions that repeatedly reset the trajectory of life, and the Snowball Earth episodes, when our planet experienced its most extreme glaciation. Drawing on more than two decades of fieldwork across Himalaya and Peninsular India, among ancient rocks, minerals, and fossils that bear direct witness to these planetary transformations, it explores how geologists reconstruct Earth’s early history from evidence preserved in the geological archives. Taken together, these geological events reveal a recurring pattern: Earth is a dynamic system in which every major crisis has also created the conditions for new and often more complex forms of life to evolve. That pattern, written into rocks billions of years old, continues to shape the planet today.    I first learned to listen to rocks long before I had the words to describe what that meant.  It began in the Himalaya, the youngest mountain range on Earth, still rising, still deforming, and still recording the ongoing collision between continents. During my early fieldwork, I spent long days mapping folded strata, tracing fault scarps, and trying to understand how landscapes preserve evidence of processes operating across vastly different geological timescales. At that time, I often felt that the mountains were trying to say something in a language I had not yet learned. Over time, through fieldwork, mapping, and countless hours spent among rocks and sediments, I began to decipher that silent language.  The lesson deepened across many other landscapes of India....

Jaishri Sanwal Bhatt is an Indian geologist and paleoclimatologist based at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bangalore, where she combines scientific research with a strong commitment to public outreach, advocacy, and science communication. For more than twenty years, Sanwal’s work has centered on reconstructing past climate change and active tectonic processes through the study of cave records and other geological proxies, especially paleolakes and speleothems. Her research has spanned the Indian and Nepalese Himalayas, the Andaman Islands, and both the eastern and western coasts of India, engaging major questions related to earth systems, water security, and natural hazards. In this wide-ranging and engaging InterDialogue, we discuss deep geological time, the proposed nuclear energy transition in India, the value of interdisciplinarity and clearer scientific communication, Sanwal’s efforts to organize science outreach initiatives in rural India, and much more.

Sunil Mukhi is an Indian theoretical physicist at the Indian Institute of Science Education and Research (IISER) in Pune, Maharashtra. Mukhi has led a distinguished career in theoretical particle physics. He received his PhD from Stony Brook University before joining the prestigious Tata Institute of Fundamental Research in Mumbai, where he worked for 27 years. In 2012, he joined IISER Pune as chair of the physics department, where he is now an honorary emeritus professor and the Raja Ramanna Chair. Throughout the years, Mukhi has held sabbatical positions at CERN in Geneva, the Institute for Advanced Study at Princeton University, and Trinity College at the University of Cambridge. He is a fellow of the Indian Academy of Sciences, the Indian National Science Academy, and the World Academy of Sciences. In 1999, he received the Shanti Swarup Bhatnagar Prize, one of India’s highest science awards, for his contributions to theoretical physics. In this InterDialogue, we begin by speaking about Mukhi’s advisory work on academic ethics, the structural incentives for academic misconduct, his concerns about AI use in academia and the difficulties of curtailing it, and India’s international scientific standing. We then speak about Mukhi’s research and contributions to theoretical physics, especially in the field of string theory. Mukhi also discusses his personal background, his career trajectory, and his reasons for returning to India after studying in the United States. We conclude by addressing the importance of science outreach, inclusivity in science, responsible behavior in scientific and public discourse, and the importance of extracurricular interests to maintaining a healthy work-life balance.

Investment in science is a pillar for any dynamic, equitable modern society, and promoting scientific literacy across all levels of society can help foster innovation, dialogue, and consensus that crosses disciplinary and cultural boundaries. Science also helps to uncover answers to foundational questions that have captivated, confounded, and divided our species for millennia. But what is “science,” and what kind of “evidence” ensures that an approach is scientific? If we take “science” to broadly mean, in its purest sense, a “dynamic search for the truth,” or more explicitly, “the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence,” as the Science Council aptly defines it, then science extends beyond the established, highly specialized disciplines of reductionist natural sciences (physics, chemistry, biology, geoscience, and space science) that have been so successful in fostering our understanding of our planet and the cosmos. Under this definition, science also includes the rigorous data-driven (qualitative and quantitative) social sciences, the inherently non-reductionist “holistic” sciences such as ecological and Earth system sciences, and the budding interdisciplinary field of complex systems science, as well as robust traditional knowledge systems based on multi-generational experiences, observations, and reasoning. As with science, “evidence” can mean a lot of things as well, including primary research, pre-existing data, past and planned experiments, and the referencing of peer-reviewed publications and primary sources. It can also include local and traditional knowledge, thought experiments, theoretical proofs, contemplation, verifiable personal experience, and empirical observation. Broadening and weaving together these forms of scientific evidence holds the potential to address complex, interconnected global challenges and explain deep mysteries that could help unify our polarized societies around foundational understandings. Foundational Questions Foundational questions can transcend the divides of generations and cultures: Cosmology, physics, and evolutionary biology have shed...
