Bridging the Gaps: A Portal for Curious Minds

Astronomy tells the story of humanity's journey from viewing the sky as a flat, two-dimensional dome to understanding it as a vast, dynamic, and ever-expanding three-dimensional universe. This enduring story has been told through countless books, brought to life in words, and crafted into both prose and poetry. But imagine a book that goes beyond simply telling the tale—a book that invites you to actively engage with it, exploring the depths of the universe as unveiled by the most advanced astronomical research and discoveries of our time. The book “Welcome to the Universe in 3D: A Visual Tour” invites you on a captivating journey through the observable universe, showcasing some of the most awe-inspiring sights in the cosmos—in stunning 3D. Featuring a dazzling collection of stereoscopic color images and with a special stereo viewer conveniently folded into the book's cover, you can experience your cosmic surroundings in a breathtaking new dimension. In this episode of Bridging the Gaps, I speak with Dr Neil deGrasse Tyson, one of the authors of this fascinating and truly one-of-a-kind book. Neil deGrasse Tyson is a renowned science communicator and the first Frederick P. Rose Director of the Hayden Planetarium at the American Museum of Natural History in New York City, where he is also a research associate in astrophysics. Tyson has received 27 honorary doctorates and the NASA Distinguished Public Service Medal. His legacy is further honored with asteroid “13123 Tyson” and a leaping frog species, "Indirani tysoni", named after him. We begin by discussing the inspiration behind a book with a built-in stereoscopic viewer and the science behind creating 3D images that come alive through the brain’s intricate processing. This leads to reflections on humanity’s discovery of the universe’s three-dimensional nature, aided by concepts like parallax. We explore some of the book’s stunning images, showcasing the cosmos in breathtaking depth, and address challenges in science communication amidst misinformation. The role of policymakers in promoting science as a societal benefit and the future of space exploration are also key topics. This has been a captivating and enlightening conversation, filled with moments of Neil deGrasse Tyson’s signature laughter. We conclude with his inspiring words: “Very happy to help you and others bridge whatever gaps need bridged.” Complement this discussion with ““The Joy of Science” with Professor Jim Al-Khalili” available at: https://www.bridgingthegaps.ie/2022/05/the-joy-of-science-with-professor-jim-al-khalili/ And then listen to ““A Traveller’s Guide to the Stars” with Physicist, Author and Nasa Technologist Les Johnson” available at: https://www.bridgingthegaps.ie/2023/03/a-travellers-guide-to-the-stars-with-physicist-author-and-nasa-technologist-les-johnson/

“The Evolution of Biological Information” with Professor Christoph Adami

Consider this thought-provoking statement: “Life is information that maintains itself.” This argument, proposed by Professor Christoph Adami in his book “The Evolution of Biological Information: How Evolution Creates Complexity, from Viruses to Brains” places information at the heart of biological systems. Adami's innovative perspective offers fresh insights into phenomena such as the evolution of drug resistance in viruses, the development of cellular communication, and the emergence of intelligence. By framing information as the unifying principle of biology, this approach provides a systematic way to explore the origin of life—both on Earth and beyond. In this episode of Bridging the Gaps I speak with Professor Christoph Adami. Christoph Adami is professor of microbiology and molecular genetics & physics as well as astronomy at Michigan State University. A pioneer in the application of methods from information theory to the study of evolution, he designed the Avida system that launched the use of digital life as a tool for investigating basic questions in evolutionary biology. He has received several awards, including the NASA Exceptional Achievement Medal and the Lifetime Achievement Award from the International Society for Artificial Life. We begin with an in-depth exploration of Shannon’s information theory, focusing particularly on the concept of entropy. This foundation sets the stage for a discussion on how biological systems store and preserve information. We delve into the information content of genes and proteins, highlighting a key idea from the book: “Living organisms know some very important facts about the world they inhabit and thrive in.” Next, we examine the concept of genetic information and its storage within DNA molecules and genomes. This includes a detailed look at the nature of this information and the latest understanding of the data encoded within the genome. We then turn to the core mechanisms—or laws—of evolution: inheritance, variation, and selection, framing these processes as the measurement, processing, and transmission of information. To describe evolution through the lens of information theory, Adami incorporates the concept of Maxwell’s demon, a thought experiment that challenges the second law of thermodynamics. We discuss this thought experiment in detail and its application to understanding the evolution of biological information. Finally, we explore the profound question of the origin of life, accompanied by an engaging discussion on viruses. Before finishing this discussion, we also touch upon the nature and challenges of multidisciplinary research. Overall, this has been an enlightening and highly informative journey into the intersection of biology and information theory.

“From Sensing to Sentience: How Feeling Emerges from the Brain” with Professor Todd Feinberg

Sentience is the feeling aspect of consciousness, encompassing the capacity to experience sensations such as pain, pleasure, and emotions. It is the foundation of subjective experience, distinguishing beings that can feel from those that merely process information or react reflexively. Sentience is a crucial component of consciousness. A key question in studying sentience is how it emerges—whether it arises from complex neural processes, a particular form of computation, or something more fundamental. In his book “From Sensing to Sentience: How Feeling Emerges from the Brain”, Professor Todd Feinberg introduces “Neurobiological Emergentism (NBE)”, a theory explaining how sentience naturally arises as an emergent property of brain functions. Emergent properties are features of a system that do not exist in its individual parts but arise through their interactions. Integrating biological, neurobiological, evolutionary, and philosophical perspectives, Feinberg argues that sentience emerges as a “system-level property” of complex neural interactions. In this episode of Bridging the Gaps, I speak with Professor Todd Feinbergy. Dr. Todd Feinberg is a board certified neurologist and psychiatrist and Clinical Professor of Psychiatry at the Icahn School Medicine at Mount Sinai in New York City. We begin by exploring the basic sensory abilities of single-celled organisms, examining how they react to their environment and survive. We then trace the evolution of multicellular organisms, discussing that when they developed into more complex systems, there is a broader substrate for sensing. A key focus is how sensory abilities laid the foundation for the evolution of advanced neurobiological systems, ultimately leading to sentience. We discuss in detail how simple sensory functions in early life forms gradually evolved into the rich experiences of animals with complex nervous systems. A central idea in the book is that “sentience emerges” as a property of complex neural systems. This perspective helps bridge the gap between neuroscience and philosophy, providing a natural explanation for how subjective experiences arise from the brain. We explore this argument in depth. Overall, this discussion provides valuable insights into the origins of sentience and its role in the evolution of consciousness.
