Bridging the Gaps: A Portal for Curious Minds

Most history of science publications narrowly focus on specific periods in human history, or particular disciplines of scientific discovery, or small sets of scientists and philosophers. However there is a view that history of science can be better understood against the background of a history of knowledge including not only theoretical but also intuitive and practical knowledge. This can be further broadened by including cognitive, material and social dimensions of knowledge. Studying how knowledge structures are formed and evolve as knowledge spreads should further enrich our understanding of development and progress of science and technology. In his new book “ The Evolution of Knowledge: Rethinking Science for the Anthropocene” Jürgen Renn presents a new way of thinking about the history of science and technology, one that offers a grand narrative of human history in which knowledge serves as a critical factor of cultural evolution. Jürgen Renn is a director at the Max Planck Institute for the History of Science in Berlin, where, together with his group, he researches structural changes in systems of knowledge. Jürgen Renn is honorary professor for History of Science at both the Humboldt-Universität and the Freie Universität Berlin. He is currently serving as Chairperson of the Humanities Sciences Section of the Max Planck Society. In this book Jürgen Renn examines the role of knowledge in global transformations going back to the dawn of civilization while providing vital perspectives on the complex challenges confronting us today in the Anthropocene—this new geological epoch shaped by humankind. He reframes the history of science and technology within a much broader history of knowledge, analyzing key episodes such as the evolution of writing, the emergence of science in the ancient world, the Scientific Revolution of early modernity, the globalization of knowledge, industrialization, and the profound transformations wrought by modern science. He investigates the evolution of knowledge using an array of disciplines and methods, from cognitive science and experimental psychology to earth science and evolutionary biology. The result is an entirely new framework for understanding structural changes in systems of knowledge—and a bold new approach to the history and philosophy of science. In this episode of Bridging the Gaps, I speak with professor Jürgen Renn, one of today’s preeminent historians of science. We discuss fascinating research that he presents in The Evolution of Knowledge. We discuss the origin, evolution and spread of knowledge, and other insights that Jürgen Renn discuss in this thorough book.

In the era of big data and super-fast information capturing and processing systems, it is easy to imagine that we have all the information that lead to actionable insights, that we need to make good decisions. However, according to David Hand, Emeritus Professor of Mathematics and Senior Research Investigator at Imperial College London, the data we have are never complete. Just as much of the universe is composed of dark matter, invisible to us but nonetheless present, the universe of information is full of dark data that we overlook at our peril. In his new book “Dark Data: Why What You Don’t Know Matters” Professor David Hand takes us on a fascinating and enlightening journey into the world of the data we don't see. As in his book “Brief Answers to the Big Questions” Stephen Hawking notes “No matter how powerful a computer you have, if you put lousy data in you will get lousy predictions out”, it is essential to understand anomalies and imperfections that a dataset may have. These imperfections may lead to incorrect and misleading insights. The book “Dark Data: Why What You Don’t Know Matters” explores the many ways in which we can be blind to missing data and how that can lead us to conclusions and actions that are mistaken, dangerous, or even disastrous. Full of real-life examples, from the Challenger shuttle explosion to complex financial frauds, the book outlines a practical taxonomy of the types of dark data that exist and the situations in which they can arise, and informs the readers how to recognize and control dark data. Professor David Hand guides us not only to be alert to the problems presented by the things we don’t know, but also shows how dark data can be used to our advantage, leading to greater understanding and better decisions. Data is essential for decision making; the books shows us all how to reduce the risk of making bad decisions.

Mathematics is everywhere. We use numbers, quantities, values and measurements almost all the time. Counting and quantifying is part of almost everything that we do. An interesting question is how did it all start. When did humans start thinking mathematically and what is the origin of mathematical thinking. As we start tacking these questions, we stumble upon few more queries: how did our brain evolve to do mathematics; what are fundamental capacities that enable humans to do mathematical thinking; what are major milestones in the evolution of mathematical thinking and in the history of mathematical innovations; is mathematics discovered or is it invented. I invited Dr Keith Devlin to join me in this episode of Bridging the Gaps for a discussion that focuses on these questions. Dr Keith Devlin is the director of the Stanford Mathematics outreach project at Stanford University. His current research is focused on the use of different media to teach and communicate mathematics to diverse audiences. He has written 33 books and over 80 research articles. He is a World Economic Forum Fellow, a Fellow of the American Association for the Advancement of Science, and a Fellow of the American Mathematical Society.

Our planet’s history, from its initial formation to present day, spans over a long period of time. It is not easy to conceptually imagine such a large timescale and most of us adopt a narrow perspective of temporal proportion. This constricted view, according to professor Marcia Bjornerud underlies many of the environmental problems we are creating for ourselves. The lifespan of Earth can seem unfathomable compared to the brevity of human existence, but a narrow view of time makes it difficult for us to understand our roots in Earth’s history and the magnitude of our impact on the planet. Bjornerud, in her recent book “Timefulness: How Thinking Life a Geologist Can Help Save the World” stresses that an awareness of Earth’s temporal rhythms is critical to our planetary survival. I speak with Professor Marcia Bjornerud in this episode of Bridging the Gaps and we discuss fascinating research and intriguing ideas that she presents in this book. We explore in detail, one of the main points presented in this book, which is “how knowing the rhythms of Earth’s deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future”. Bjornerud emphasizes that overlapping rates of change in the Earth system -- some fast some slow-- require a poly-temporal worldview that she calls “timefulness”. Marcia Bjornerud is professor of geology and environmental studies at Lawrence University. She is the author of Reading the Rocks: The Autobiography of the Earth and a contributing writer for Elements, the New Yorker's science and technology blog. “Timefulness: How Thinking Like a Geologist Can Help Save the World” presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. “Timefulness reveals how knowing the rhythms of Earth’s deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future. Featuring illustrations by Haley Hagerman, this compelling book offers a new way of thinking about our place in time, showing how our everyday lives are shaped by processes that vastly predate us, and how our actions today will in turn have consequences that will outlast us by generations”.

An intriguing set of questions that is being explored by researchers across the globe and is being discussed and brainstormed in various organisations and think tanks is: “what is the future of work”; “how forthcoming AI and Automation revolution will impact on the nature and structure of work”; and “what would be the impact of these changes on the fabric of society from social, economic and political perspectives”. In a 2013 study “The Future of Employment: How Susceptible are Jobs to Computerisation?” researchers Dr Carl Benedikt Frey and Dr Michael Osborne made an important observation: about 47% jobs in the US will be lost to automation. Dr Carl Frey is the co-director of programme on technology and employment at Oxford Martin School at Oxford University. His research focuses on “how advances in digital technology are reshaping the nature of work and jobs and what that might mean for the future”. In 2016, he was named the 2nd most influential young opinion leader by the Swedish business magazine Veckans Affärer. A recent book by Dr Carl Frey presents a thorough review of the history of technological progress and how it has radically shifted the distribution of economic and political power among society’s members. The title of the book is “The Technology Trap: Capital, Labour and Power in the Age of Automation”. The Industrial Revolution was a defining moment in history, but few grasped its enormous consequences at the time. This books demonstrates that the lessons of the past can help us to more effectively face the present and the forthcoming AI and automation revolution. Dr Carl Frey shows the Industrial Revolution created unprecedented wealth and prosperity over the long run, but the immediate consequences of mechanization were devastating for large swaths of the population. Middle-income jobs withered, wages stagnated, the labour share of income fell, profits surged, and economic inequality skyrocketed. These trends, Frey documents, broadly mirror those in our current age of automation, which began with the Computer Revolution. Just as the Industrial Revolution eventually brought about extraordinary benefits for society, artificial intelligence systems have the potential to do the same. But Frey argues that this depends on how the short term is managed. The decisions that we make now and the policies that we develop and adopt now will have profound impact on the future of work and job market. In the nineteenth century, workers violently expressed their concerns over machines taking their jobs. The Luddite uprisings joined a long wave of machinery riots that swept across Europe and China. Today’s despairing middle class has not resorted to physical force, but their frustration has led to rising populism and the increasing fragmentation of society. As middle-class jobs continue to come under pressure, there’s no assurance that positive attitudes to technology will persist. Dr Carl Frey joins me for this episode of Bridging the Gaps. In this podcast we discuss the ideas that Dr Frey presents in this book. Before discussing the future of work, we look at the history of work and how the nature of work evolved through various ages and how did it impact the equality in the society. Dr Frey notes in his book that the age of inequality began with the Neolithic revolution; we discuss this in detail. We then discussed first and second industrial revolutions and the age of digital transformation. We also discuss the rise of politics of polarisation and finally we discuss the future of work. This has been a fascinating conversation with a thought leader, on a hugely important subject.

Humans are the only animals that cook their food. One of the implications of cooking food, as noted by Oliver Goldsmith is, “of all other animals we spend the least time in eating”. In a ground-breaking theory of our origins, primatologist Richard Wrangham argues that the shift from raw to cooked food was a key factor in human development. When our ancestors adapted to using fire, humanity as we know it, began. Wrangham notes that as a result of eating cooked food, the human digestive tract shrank and the brain grew. Eating cooked plants or meat makes digestion easier and the energy we formerly spent on digestion was freed up, enabling our brains to grow. Cooking increases the proportion of nutrients that can be digested, makes food easier to digest and kills pathogens (harmful bacteria and viruses). Time once spent chewing tough food could be used instead to hunt and undertake other tasks and activities. Cooking became the basis for pair bonding and marriage, created household and shaped family structures, and even led to a gender based division of labour. Richard Wrangham is a professor of Biological Anthropology at Harvard University and founded the Kibale Chimpanzee Project in 1987. He has conducted extensive research on primate ecology, nutrition, and social behaviour. In his book “Catching Fire: How Cooking Made Us Human” Wrangham argues that cooking food is obligatory for humans as a result of biological adaptations and the cooking, in particular, the consumption of cooked food might explain the increase in human brain size, smaller teeth and jaws, and smaller more effective digestive system. Wrangham’s “Catching Fire” presents an interesting narrative that how we came to be the social and intelligent beings that we are today. “Cooking was a great discovery not merely because it gave us better food, or even because it made us physically human. It did something even more important: it helped make our brains uniquely large, providing a dull human body with a brilliant human mind” – Richard Wrangham For more high quality in-depth discussions with researchers and thought leaders, reach us at: https://www.bridgingthegaps.ie/ https://soundcloud.com/bridging-the-gaps

Since 2003, in a unique Earth-trailing orbit around the sun, the Spitzer Space Telescope has been observing in infrared an optically invisible universe dominated by dust and stars. Astronomers have been studying visible universe for thousands of years; however due to interstellar dust clouds and other obstructions to visible light, it was not possible to observe various regions of the universe. The Spitzer Space Telescope, the most sensitive infrared space observatory ever launched, has enabled us to study such optically obscure regions and processes in infrared. “The Spitzer Space Telescope has opened up a new window on the cosmos, yielding new perspectives and crucial insights into the genesis of planets, stars and galaxies”. Michael Werner and Peter Eisenhardt are among the scientists who worked for decades to bring this historic mission to life. Their book “More Things in the Heavens: How infrared astronomy is expanding our view of the universe” outlines an inside story of how Spitzer continues to carry out cutting-edge infrared astronomy to help answer fundamental questions that have intrigued humankind since ancient time: Where did we come from? How did the universe evolve? Are we alone? In this episode of Bridging the Gaps podcast, I speak with Michael Werner, one of the authors of this insightful book. Discussing various features of Spitzer’s mission and numerous topics covered in the book, this podcast presents a fascinating view of how infrared astronomy is aiding the search for exoplanets, enabling us to study exoplanet atmospheres, and is transforming our understanding of formation of stars and galaxies, and of the history and evolution of our universe. Michael Werner is a senior research scientists at the NASA Jet Propulsion Laboratory, California Institute of Technology. He has been the lead scientist for the Spitzer Space Telescope since 1984.

In his new book, "Irrationality: A History of the Dark Side of Reason" philosopher Justin Smith presents a fascinating narrative that reveals the ways in which the pursuit of rationality often leads to an explosion of irrationality. Smith, a professor of the history and philosophy of science at the University of Paris, acknowledges that we are living in an era when nothing seems to make sense. Populism is on the rise, pseudoscience is still around and there is no shortage of of conspiracy theories. Smith discusses the core of the problem that the rational gives birth to the irrational and vice versa in an endless cycle, and any effort to permanently set things in order sooner or later ends in an explosion of unreason. He notes that despite the fact logic and reason are well understood, methods and practises that were supposed to have been setup to counter irrationality, ended up mired in the very problem that they were meant to solve, and that is irrationality. "Irrationality: A History of the Dark Side of Reason" is rich and ambitious and ranges across philosophy, politics and current events. It challenges conventional thinking about logic, natural reason, dreams, art and science, pseudoscience, the Enlightenment, the internet, jokes and lies and death and shows how history reveals that any triumph of reason is temporary and reversible, and that rational schemes often result in their polar opposite. Smith argues that it is irrational to try to eliminate irrationality and describes irrationality an ineradicable feature of life. It has been an absolute pleasure speaking with Professor Justin Smith in this episode of Bridging the Gaps. This has been a fascinating conversation.

Professor Toby Walsh is a world leader in the field of artificial intelligence, and has spent his life dreaming about machines that might think. He is a Professor of AI at the University of New South Wales and leads a research group at Data61, Australia’s Centre of Excellence for ICT Research. In this episode of Bridging the Gaps Professor Toby Walsh discusses his latest book ““2062: The World That AI Made”. By 2062 there will be huge developments in the field of Artificial Intelligence and some researchers believe that by that time we will have built machines as intelligent as us. But what will this future actually look like? When the quest to build intelligent machines has been successful, how will life on this planet unfold? In 2062, Toby Walsh considers the impact AI will have on work, war, politics, economics, everyday human life and, indeed, human death. Will robots become conscious? Will automation take away jobs? Will we become immortal machines ourselves, uploading our brains to the cloud? What lies in store for homo digitalis – the people of the not-so-distant future who will be living among fully functioning artificial intelligence? In “2062: The World That AI Made” Professor Toby Walsh describes the choices we need to make today to ensure that future remains bright.

Adrienne Mayor is an author and historian of ancient science and human curiosity. She is a research scholar at Stanford University who investigates natural knowledge contained in pre-scientific myths and traditions. In this podcast Adrienne Mayor discusses the fascinating research that she presents in her book "Gods and Robots: Myths, Machines and Ancient Dreams of Technology". This is a captivating account of the earliest expressions of the enduring urge to create machines that imitate life. Adrienne Mayor presents ancient Greek, Roman, Indian and Chinese myths and traditions that envisioned artificial life, robots and self moving contraptions. It is interesting to observe that some of today's most advanced innovations in robotics and artificial intelligence were envisaged and imagined in ancient myths and traditions. After discussing a number of myths and traditions, Adrienne Mayor presents stories of a number of real machines and innovations that were developed long before the age of modern science and technology. This book is an account of ingenuity and creativity, and that how science has always been driven by imagination.
