Science communication plays an important role in bridging the gap between researchers and the general public, fostering understanding, engagement, and appreciation for scientific explorations and advancements. In an era where science and technology shape every aspect of our lives, effective communication of research findings is more critical than ever. This is also a time where there are conflicting views about scientific work and polarizations in societies. This makes effective science communication even more important not only to ensure that scientific knowledge is accessible to all, but also to empower individuals to make informed decisions, influences policy-making, and fosters trust in the scientific community. However, effective science communication goes beyond simply disseminating information; it requires clarity, creativity, and engagement strategies tailored to diverse audiences. By employing clear language and compelling storytelling researchers can effectively communicate their findings, thereby enhancing public awareness and understanding of the profound impact that science has on society. In his recent book “Sharing Our Science: How to Write and Speak STEM” Professor Brandon Brown, a scientist-turned-writing teacher, provides a highly valuable resource for STEM practitioners aiming to effectively convey their technical work to both specialised and general audiences. In this episode of Bridging the Gaps I speak with Professor Brandon Brown; we discuss this personal, practical, and inspirational guide for scientists and technical professionals seeking to enhance their written and oral communication skills in STEM fields. Brandon Brown is a Professor of Physics and communications specialist at the University of San Francisco. He is an excellent science communicator. He has written for publications such as Slate, Smithsonian, and Scientific American and served as Deputy Director at the Green Science Policy Institute and a Senior Writing Coach for the Strictly Speaking Group. We begin by exploring the significance of storytelling in effective science communication, delving into diverse tools and approaches such as tension and narrative to enhance the communication of scientific concepts. We further examine the utilisation of relatable examples, including simplifying large numbers and intricate comparisons like the size of an atom relative to its nucleus, to improve clarity and facilitate comprehension. We also address the detrimental effects of disinformation on science communication, which can lead to societal polarisation and divisions. We also reflect on Professor Brandon Brown's personal encounters, highlighting how adept communication of challenging facts can profoundly influence individuals. This has been both informative and insightful discussion.

We live in a society driven by a relentless pursuit of greatness, where we are constantly pushed to attain the highest levels of wealth, power, and fame. This relentless fixation on greatness leads to stress and anxiety, strains our interpersonal connections, fosters extensive political and economic disparities, and contributes to the deterioration of our natural environment. In his book “The Good-Enough Life” author and educator Avram Alpert explores the idea of whether embracing our limitations could pave the way to a more satisfying existence and a more harmonious society. He explains why the relentless pursuit of competition within our social structure ultimately yields no real advantages for anyone and offers a vision of an alternative way of life—an inclusive, good-enough life for all. In this episode of Bridging the Gaps I speak with Dr Avram Alpert Dr Avram Alpert is a writer and teacher. He has worked at Princeton and Rutgers Universities, and is currently a research fellow at the New Institute in Hamburg. His work has appeared in publications such as the New York Times, the Washington Post, and Aeon. We begin our conversation by discussing the concept of 'Good-Enough,' a central theme in the book. Following that, we explore the notion of 'greatness.' In particular, I engage Dr. Avram Alpert in a conversation about his perspective on the achievements of individuals who attain success and fame through their dedication and hard work. We also talk about people who have done great things and made society better. Then our discussion shifts toward the idea of fostering a more equitable and just society, emphasising the potential benefits of reduced competition among individuals. We explore the possibility of a society where each person can rediscover a sense of purpose and meaning, and have their material and emotional needs met.

We experience, thus we exist. Our conscious perceptions form the foundation of our self-awareness. They play a vital role in shaping our understanding of ourselves as sentient beings: present, alive, and significant. However, what is the origin of consciousness, and how does the process of experiencing sensations and developing a sense of awareness contribute to its emergence? Is this capacity limited solely to humans? Do other animals share this ability? And what about the potential for future machines? In his book “Sentience: The Invention of Consciousness” neuropsychologist Professor Nicholas Humphrey uncovers the evolutionary history of consciousness and argues that consciousness evolved to make us feel that life is worth living. Drawing upon his groundbreaking research on social intelligence, as well as his intriguing findings on blindsight in monkeys and profound insights into the philosophy of mind, Professor Humphrey outlines a fascinating narrative to unveil the evolutionary origins of consciousness. In this episode of Bridging the Gaps, I speak with Professor Nicholas Humphrey. Nicholas Humphrey, Emeritus Professor of Psychology at the London School of Economics, is a theoretical psychologist, who studies the evolution of intelligence and consciousness. He was the first to demonstrate the existence of “blindsight” in monkeys. He has also studied mountain gorillas with Dian Fossey in Rwanda, and proposed the celebrated theory of the “social function of intellect,”. His research holds profound significance in exploring and unravelling the mysteries of the mind and its evolutionary underpinnings. We start off by discussing the enigma surrounding the emergence of consciousness and the challenges encountered when attempting to understand its nature and origins. Professor Nicholas Humphrey's book introduces the intriguing concepts of cognitive consciousness and phenomenal consciousness, which we thoroughly explore during our conversation. We then discuss in detail the concept of sentience as presented and explained in this book. We delve into the evolutionary perspective, examining why consciousness became an adaptive trait and how it evolved within living organisms. An intriguing question arises: if our early animal ancestors possessed cognitive consciousness, how did it transition into phenomenal consciousness? Could there exist an observable threshold, such as brain size, neuron count, or processing capacity, at which cognitive consciousness transforms into phenomenal consciousness? We then discuss the fascinating notion of blindsight and its relevance to the theory of consciousness presented in the book. We then delve into the complex concept of sensations, exploring how the firing of neurons and the movement of electric signals within the brain give rise to our subjective experience of consciousness. Lastly, we explore the possibility of consciousness emerging within machines, contemplating its potential evolution beyond organic life.

Smartness has permeated our lives in the form of smartphones, smart cars, smart homes, and smart cities. It has become a mandate, a pervasive force that governs politics, economics, and the environment. As our world faces increasingly complex challenges, the drive for ubiquitous computing raises important questions. What exactly is this 'smartness mandate'? How did it emerge, and what does it reveal about our evolving understanding and management of reality? How did we come to view the planet and its inhabitants primarily as instruments for data collection? In the book 'The Smartness Mandate,' co-authored by Professor Orit Halpern, the notion of 'smartness' is presented as more than just a technology, it is presented as an epistemology — a way of knowing. In this episode of Bridging the Gaps, I speak with Professor Orit Halpern, where we delve into the concept of smartness. We explore its historical roots and its cultural implications, particularly its emphasis on data-driven technologies and decision-making processes across domains such as urban planning, healthcare, and education. Orit Halpern is Lighthouse Professor and Chair of Digital Cultures and Societal Change at Technische Universität Dresden. She completed her Ph.D. at Harvard. She has held numerous visiting scholar positions including at the Max Planck Institute for the History of Science in Berlin, IKKM Weimar, and at Duke University. At present she is working on two projects. The first project is about the history of automation, intelligence, and freedom; and the second project examines extreme infrastructures and the history of experimentation at planetary scales in design, science, and engineering. Our conversation begins by discussing the idea of “smartness” as presented in the book. To understand it better, we look at a few examples. The book suggests that the smartness paradigm relies a lot on collecting data, analysing it, as well as monitoring people through surveillance. We talk about the possible risks and consequences of this data-focused approach for personal privacy and individual rights. Next, we talk about how the smartness idea connects with the concept of resilience. We also touch on the fact, as presented in the book, that the smartness paradigm often reinforces existing power structures and inequalities. We explore the biases and ethical concerns that may arise with the use of these technologies. Furthermore, we explore the possibility of using the smartness approach to promote fairness and equality. We talk about how it could be applied to create a more just society. We discuss the significance of multidisciplinarity, and the role of higher education institutions and educators to create an enabling environment for an informed discourse to address these questions. Professor Orit Halpren emphasises the importance of exploring these questions and addressing relevant concerns to make sure we create the kind of world we truly want for ourselves.

It is difficult to imagine a not-so-distant past when deadly diseases were a routine part of life. Even more astonishing is the fact that during that time, prevailing medical beliefs attributed these diseases to harmful miasmas, bodily humors, and divine dyspepsia. However, a groundbreaking revelation occurred with the discovery of the world of microorganisms, which led to the understanding that these tiny organisms might be responsible for transmitting and spreading diseases. These pivotal discoveries and understandings paved the way for numerous measures and techniques to prevent the transmission of infectious diseases. The history of epidemics and humanity's progress in combating these diseases is full of captivating stories. In his new book, "Ending Epidemics: A History of Escape from Contagion," prolific author Richard Conniff outlines how our comprehension and prevention of some of the most devastating infectious diseases have advanced, consequently doubling the average life expectancy. In this episode of Bridging the Gaps, I speak with Richard Conniff, delving into moments of inspiration and innovation, decades marked by unwavering determination, and periods of profound suffering that have spurred individuals, institutions, and governments to take action in the pursuit of public health. Richard Conniff is a prolific author of several non-fiction books and many articles for magazines such as National Geographic, Simthsonian, and Time. He is a contributing opinion writer for the New York Times, and a former commentator on NPR's “All Things Considered”. He has won the National Magazine Award. He has also written and presented nature programmes for National Geographic television, the Discovery channel and the BBC. Our conversation begins with an exploration of how communities in old days grappled with epidemics, given their limited understanding of the causes behind such widespread outbreaks. We delve into the intricate ways in which communities tried to comprehend and interpret illnesses before the pivotal discoveries of microorganisms and germs. An engaging segment follows, chronicling the efforts of early pioneers who harnessed the power of microscopes to identify microorganisms believed to be responsible for various diseases. One captivating narrative we explore revolves around the remarkable utilization of cowpox to foster immunity against smallpox—an extraordinary breakthrough in the history of medicine. However, we also address the resistance encountered by these novel ideas and concepts. We then delve into the emergence of the concept of immunity, the discovery of microorganisms, and the subsequent development of vaccines and antibiotics. Additionally, we discuss the profound realization that improved sanitary conditions are indispensable for safeguarding public health. Naturally, our conversation turns towards the recent Covid-19 epidemic, examining humanity's response to this global crisis. Richard offers a significant insight that despite our enhanced capabilities in dealing with epidemics, these formidable diseases persist and may pose future threats if we fail to remain vigilant to the dangers they present.

When considering the long-term survival and sustainability of human civilization, two developments hold significant implications. Firstly, humanity has been recklessly depleting resources, causing species extinctions, and degrading essential elements for life on Earth for centuries. Secondly, advancements in the science of discovering habitable planets outside our solar system have opened up the possibility of establishing human civilization beyond our increasingly inhospitable planetary home. In his latest book, "Worlds Without End: Exoplanets, Habitability, and the Future of Humanity," Professor Chris Impey takes readers on a thrilling journey through the frontiers of astronomy and the search for planets that can potentially support life. In this episode of Bridging the Gaps, I speak with Professor Impey about the science behind finding habitable exoplanets, the evolution of space exploration, and the prospect of humans inhabiting a planet far away from our solar system. Chris Impey is a University Distinguished Professor of Astronomy at the University of Arizona. He has made significant contributions to the fields of observational cosmology, astrophysics, particularly in the area of exoplanet research. His expertise and passion for the subject have led to many publications and appearances in documentaries, news outlets, and popular science programmes. He has won numerous teaching awards and authored textbooks and many popular science books. We begin our discussion by examining the historical perspectives on exoplanets, planets beyond our solar system. We then delve into the discovery of the first exoplanet and explore the various methods that scientists have employed to detect these far-off worlds. The Kepler Space Telescope played a pivotal role in this field, and we explore how the James Webb Telescope presents new opportunities for advancing exoplanet research. The diversity of exoplanets is astounding, with variations in size, composition, and orbital characteristics. We delve into these differences and their implications. Additionally, we thoroughly examine the concept of habitability, including how scientists are studying the atmospheric characteristics of these alien worlds. We also touch on the intriguing possibility of orphan planets - large planets without a star - that may sustain habitability characteristics without a sun. We then contemplate the prospect of travelling to these distant planets and potentially establishing human settlements there. We explore the magnitude of such a journey and the challenges involved in interstellar travel. Lastly, we consider the possibility of extraterrestrial life in the universe.

The future of technology is a subject of debate among experts. Some predict a bleak future where robots become dominant, leaving humans behind. Others, known as tech industry boosters, believe that replacing humans with software can lead to a better world. Critics of the tech industry express concern about the negative consequences of surveillance capitalism. Despite these differences, there is a shared belief that machines will eventually surpass humans in most areas. In his recent book "How to Stay Smart in a Smart World: Why Human Intelligence Still Beats Algorithms" professor Gerd Gigerenzer argues against this notion and offers insights on how we can maintain control in a world where algorithms are prevalent. In this episode of Bridging the Gaps, I speak with professor Gerd Gigerenzer to discuss challenges posed by rapid developments in the tech sector, particularly in the field of artificial intelligence. We discuss different approaches that individuals can adopt to enhance their awareness of the potential hazards that come with using such systems and explore strategies to maintain control in a world where algorithms play a significant role. Gerd Gigerenzer is a psychologist and researcher who has made significant contributions to the fields of cognitive psychology and decision-making. He is director emeritus at the Max Planck Institute for Human Development, and is director of the Harding Center for Risk Literacy at the University of Potsdam. He is a professor of psychology at the University of Chicago and is a visiting professor at the University of Virginia. His research focuses on how people make decisions under conditions of uncertainty and how to improve people's understanding of risk and probability. He has trained judges, physicians, and managers in decision-making and understanding risk. Our discussion begins by exploring the limitations of present-day narrow and task-specific artificial intelligence systems in dealing with complex scenarios. Professor Gerd Gigerenzer's argument that simple heuristics may outperform complex algorithms in solving complex problems is particularly noteworthy. In fact, in some complex scenarios, relying on our intuition or "gut feelings" may result in better decisions than relying on sophisticated technological systems. We then discuss the importance of assessing the risks associated with using seemingly free services that actually collect and exploit users' data and information to sustain their business models. We delve into the topic of recommender systems that subtly influence users' choices by nudging them towards certain features, services, or information. Next, we examine various strategies for individuals to become more mindful of the potential risks associated with using such systems, and consider ways to maintain control in a world where algorithms wield considerable influence. This has been an insightful discussion.

The ancient ambition of exploring the cosmos and possibly even inhabiting other planets may one day come true, as we discover more and more exoplanets and intend to develop innovative propulsion techniques suitable for interstellar travel. Projects like 100 Year Starship and Breakthrough Starshot enable us to study the challenges involved with a view to develop solutions, furthering the idea of interstellar travel. In his new book “A Traveller’s Guide to the Stars” physicist and Nasa Technologist Les Johnson takes the readers on an exciting journey through the science and innovations that could help us get to the stars.The book gives a thorough account of the next great frontier of human exploration, outlining exclusive inside look at the amazing advances in science and technology that will aid today's astronauts in setting out for the stars. Les Johnson is a physicist, author, and NASA technologist. He leads the development of advanced, in-space spacecraft propulsion technologies at the NASA George C. Marshall Space Flight Center in Huntsville, Alabama. During his career at NASA, Les served as the Manager for the Space Science Programs and Projects Office, the In-Space Propulsion Technology Project, and the Interstellar Propulsion Research Project. We begin by reviewing the impact of discovery of exoplanets on the ambition of travelling to and inhibiting these distant alien worlds. Next we look at the precursors that we must take into consideration before building the ships and embarking on interstellar journeys. We discuss in detail the presently used propulsion technologies and evaluate their shortcomings for interstellar journeys. While discussing the future, we first discuss in detail two rocket technologies of the future: nuclear fusion and antimatter. Then we discuss in detail the innovative and promising propulsion approaches such as solar sails and laser-beamed energy. We discuss in detail how these technologies may one day enable us to embark on interstellar journeys. Les Johnson has written a number of science fiction books; I ask him to expand on his view that science fiction is an effective tool to imagine future technologies. No discussion on the topic of space exploration is complete without discussing the possibility of life out there; we discuss this as I ask Les to give us his views on the possibility of life out there and on the question “are we alone”. This has been a fantastic discussion.

Looking for the earliest galaxies is like travelling back in time. Something that astronomers do all the time. Astronomers use huge and powerful telescopes to see not only farther and deeper into space, but also back in time. The hunt for the oldest galaxies using observational astronomy needs not only a thorough grasp of the physics and chemistry of the early cosmos, but also the human ingenuity of building large size telescopes and designing innovative instrumentation. Large and complicated telescopes, as well as supporting processes, techniques, and devices, allow astronomers to make more clear and accurate observations in their search for the first galaxies. In his new book “When Galaxies Were Born: The Quest for Cosmic Dawn” professor Richard Ellis presents a firsthand narrative of how a pioneering group of scientists used the world's greatest telescopes to unravel the history of the universe and witness cosmic dawn, when starlight first illuminated the cosmos and galaxies formed from darkness. The book also gives a narrative of a golden age of astronomy, outlining many achievements and disappointments, and discussing rivalries with competing teams. This is also an account of professor Elis’s remarkable career spanning more than forty years. In this episode of Bridging the Gaps I speak with professor Richard Ellis. We discuss amazing progres that astronomers have made in building ever larger and more powerful telescopes; we also dig deep on the fascinating research on the birth of galaxies and our quest for the cosmic dawn. Richard S. Ellis is professor of astrophysics at University College London and a world-renowned observational astronomer who has made numerous discoveries about the nature and evolution of the universe. We start off discussing the human aspects of observational astronomy where teams from all over the world first compete for participating in constructing large telescopes and then compete for securing blocks of time to make observations. We review the taxonomy of large and most powerful ground based telescopes and discuss effectiveness and contribution of space telescopes towards observational astronomy. First light in the universe and the assembly of galaxies in the early universe are among the four main areas that the James Webb Space Telescope will focus on. We dig deep on these points, and what expectations researchers have from this new space telescope. We then discuss how human ingenuity has led to the development of techniques such as adaptive mirrors and application of gravitational lensing to improve our observations. We then focus on the cutting edge research on the quest for cosmic dawn and dig deep on the physics and chemistry of the early universe. We discuss the role dark matter might have played in the formation of early galaxies. We also touch upon the origin of life in the universe, and briefly debate the question “are we alone”. This has been a fun discussion that is highly informative.
