Bridging the Gaps: A Portal for Curious Minds

How does a network of individual neural cells become a brain? How does a neural network learn, hold information and exhibit intelligence? While neurobiologists study how nature achieves this feat, computer scientists interested in artificial intelligence attempt to achieve it through technology. Are there ideas that researchers in the field of artificial intelligence borrow from their counterparts in the field of neuroscience? Can a better understanding of the development and working of the biological brain lead to the development of improved AI? In his book “The Self-Assembling Brain: How Neural Networks Grow Smarter” professor Peter Robin Hiesinger explores stories of both fields exploring the historical and modern approaches. In this episode of Bridging the Gaps, I speak with professor Peter Robin Hiesinger about the relationship between what we know about the development and working of biological brains and the approaches used to design artificial intelligence systems. We start our conversation by reviewing the fascinating research that led to the development of neural theory. Professor Hiesigner suggests in the book that to understand what makes a neural network intelligent we must find the answer to the question: is this connectivity or is this learning that makes a neural network intelligent; we look into this argument. We then discuss “the information problem” that how we get information in the brain that makes it intelligent. We also look at the nature vs nurture debate and discuss examples of butterflies that take multigenerational trip, and scout bees that inform the bees in the hive the location and distance of the food. We also discuss the development of the biological brain by GNOME over time. We then shift the focus of discussion to artificial intelligence and explore ideas that the researchers in the field artificial intelligence can borrow from the research in the field of neuroscience. We discuss processes and approaches in the field of computing science such as Cellular Automata, Algorithmic Information Theory and Game of Life and explore their similarities with how GENOME creates the brain over time. This has been an immensely informative discussion.

Quantum computers store data and perform computations by utilizing properties of quantum physics. Quantum computations are performed by these machines by utilizing quantum state features such as superposition and entanglement. Traditional computers store data in binary “bits,” which can be either 0s or 1s. A quantum bit, or qubit, is the fundamental memory unit in a quantum computer. Quantum states such as the spin of an electron or the direction of a photon, are used to create qubits. This could be very useful for specific problems where quantum computers could considerably outperform even the most powerful supercomputers. In this episode of Bridging the Gaps I speak with professor Andrea Morello and we discuss fascinating science & engineering of conceptualizing and building quantum computers. Professor Andrea Morello helps us to unpack and tackle questions such as what a quantum computer is and how we build a quantum computer. Andrea Morello is the professor of Quantum Engineering in the School of Electrical Engineering and Telecommunications at the University of New South Wales Sydney, Australia. I begin our conversation by asking professor Morello what a quantum computer is, and how it differs from classical and conventional computers. The no-cloning theorem's implications in the field of quantum computers are next discussed. The no-cloning theorem states that it is impossible to create an independent and identical copy of an unknown quantum state. Professor Morello's team uses single-spin in silicon to construct quantum computers, and we go over their approach in depth. The true value of quantum computers can only be realised if we develop creative algorithms that make effective use of quantum computers' exponentially huge information space and processing capability. We discuss this in detail. We also touch upon the concept of quantum chaos and discuss research in this area. This has been a fascinating discussion.

Nanotechnology allows scientists to better understand, interact with, and manipulate biology by creating and manufacturing artificial structures and even machines at the nanoscale out of DNA, proteins, and other biological molecules. From nanoscale machines that can target individual cancer cells and deliver drugs more effectively to nanoantibiotics that can fight resistant bacteria, to the engineering of tissues and organs for research, drug discovery, and transplantation, nanotechnology is revolutionizing medicine in ways that will have profound effects on our health and longevity. In this episode of Bridging the Gaps I speak with Professor Sonia Contera and we discuss fascinating research that she presents in her book “Nano Comes to Life: How Nanotechnology Is Transforming Medicine and the Future of Biology”. The book introduces readers to nanotechnologies, which are fast advancing and allowing us to influence the basic building components of life. Sonia Contera provides an insider's view of this new frontier, explaining how nanotechnology permits a new sort of transdisciplinary science that has the potential to give us power over our own biology, health, and lifestyles. Sonia Contera is professor of biological physics in the Department of Physics at the University of Oxford. Her work lies at the interface of physics, biology, and nanotechnology, with a particular focus on the role of mechanics in biology. We start this discussion by looking at the scale at which nanotechnologies function. The evolution of instruments and technology that allow us to perceive and interact with matter on such a microscopic scale is then discussed. The convergence of numerous sciences that are at the heart of such breakthroughs are then discussed, allowing us to build nano-scale structures from the ground up. We then discuss the fascinating research that enables researchers to design proteins on a computer simulator, figure out what kind of GENOME will make such protein from that simulated protein, create that GENOME, and then put it in a real cell to create that protein in reality. We also touch upon the cutting edge research in DNA Nanotechnology and other enabling technologies such as Artificial Intelligence, and the future of biology and medicine. This has been a fascinating discussion.

The debate over whether or not free will exists is not new. The main points of contention in this discussion are whether or not we have control over our actions, and if so, what kind of control we have and to what extent. On the one hand, we have a strong sense of liberty, which causes us to trust in our own free will. An intuitive and instinctive sense of free will, on the other hand, could be misinterpreted. In this episode of Bridging the Gaps, I speak with Dr Aflred Mele and we discuss the concept of “Free Will” from the perspective of philosophy and from the perspective of neuroscience. Dr Alfred Mele is a Professor of Philosophy at Florida State University. His research interests include issues about human behavior located at the intersection of philosophy and science such as free will, personal autonomy, self-deception, self-control, intention, intentional action, motivation, and moral responsibility. He is also the past Director of the Philosophy and Science of Self-Control Project and the Big Questions in Free Will Project. I open this discussion by asking Dr Mele to unpack the concept of “Free Will”. I then ask Dr Mele to outline important philosophical views about the concept of “Free Will” that emerged over time. We discuss in detail the relevant concepts of determinism, compatibilism, incompatibilism, and libertarianism. We then discuss the concept of Free Will through the lens of neuroscience. We discuss a number of experiments conducted by neuroscientists. The finding of these experiments seems to suggest that that free will is an illusion. But the question is, is it right to extrapolate the findings of these experiments that focus on simple choices and are conducted in controlled environments to conclusively suggest that free will does not exist. Dr Mele discusses this point in detail. Complement this conversion with fascinating discussion with Professor Renata Salecl on the “Passion for Ignorance and Denials” available at: https://www.bridgingthegaps.ie/2020/10/a-passion-for-ignorance-and-for-denials-and-negations-with-professor-renata-salecl/ And then listen to Professor David Chalmers at: https://www.bridgingthegaps.ie/2015/03/from-consciousness-to-synthetic-consciousness-from-one-unknown-to-another-unknown-with-david-chalmers/

What is time? Is time real or just an illusion? Time is an enigma, a mystery that never ceases to perplex us. Philosophers, poets, painters and thinkers have long debated its significance, while scientists have discovered that its structure differs from our intuitive understanding of it. Our view of time has changed dramatically throughout the years, from Boltzmann to quantum theory, and from Einstein to loop quantum gravity. In the huge cosmos, time moves at various speeds in different places, the past and future differ considerably less than we might assume, and the whole concept of the present vanishes. In this episode of Bridging the Gaps I discuss with Dr Carlo Rovelli the nature of time, the nature of space, and the fundamental nature of reality through the lens of quantum mechanics. Carlo Rovelli is professor of physics at Aix-Marseille University, where he is director of the quantum gravity group at the Center for Theoretical Physics. He is one of the founders of loop quantum gravity theory and is one of the world’s biggest experts in this field. In his books and in his presentations Rovelli says time is not what we think it is. He also says that space is not what we think it is. I open our conversation by asking him to unpack these statements for us. We then discuss the “impossibility of now”. In physics, from one moment to the next, the only concept that gives some notion of continuity is the flow of heat; it is the concept of entropy. We discuss how entropy plays an important role in this perceived continuity. Along the way we touch upon the concepts of past, present and future that we hold in our minds. Dr Rovelli’s new book, Helgoland begins with a detailed description of the development of quantum theory in 1925; we discuss the main observations and discoveries that led to the development of quantum theory. We then discuss the fundamental nature of reality by unpacking the statement in one of his books “if the backdrop of space has disappeared, time has disappeared, classic particles have disappeared, along with the class fields, so then what is the world made of?” And finally we discuss the efforts to develop models and theories to reconcile general relativity with quantum theory. We discuss how loop quantum gravity theory attempts to reconcile general relativity with quantum theory.

Neurons are the fundamental building blocks of the brain. In the human brain, billions of these neurons communicate and liaise with one another using spikes, blips of electric voltages. Studying and understanding how these spikes emerge in the brain, how they travel through the brain and how this communication leads to meaningful actions are part of the cutting edge research in the field of neuroscience. In this episode of Bridging the Gaps I speak with professor Mark Humphries and discuss the research that he presents in his new book “The Spike: An Epic Journey Through The Brain in 2.1 Seconds”. This is a deeply informative account of the journey that these electrical signals take as they move from one neuron to another and eventually lead us to act. The tackles previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? In this thorough discussion with professor Mark Humphries, we touch upon these fascinating questions and intriguing concepts. Mark Humphries is Chair in Computational Neuroscience at the University of Nottingham. He is the founding editor of “the Spike” an online publication available at Medium dot com. I begin our conversation by asking Mark about the structure of an individual neuron and how spikes emerge in a single neuron. We then discuss the concept of Dark Neuron and talk about the spikes that don’t lead to new spikes and just fail. A very interesting question is what do these spikes mean and how do these spikes carry messages from one point in the brain to another. In the book, Mark reports two groups of researchers holding two different viewpoints, these are “The Timers” and “The Counters”. I ask Mark “who are the timers” and “who are the counters” and what are their viewpoints on the question that how these spikes carry messages from one point in the nervous system to another. And finally we discuss how research is conducted in the fields of neuroscience and computational neuroscience. We particularly discuss progress that the researchers are making in the field of computing neuroscience.

Over centuries “information has shaped and been shaped by human society”, writes professor Paul Duguid at the start of the book “Information: A Historical Companion”. Duguid is one of the editors of this book that reconstructs the rise of human approaches to creating, managing, and sharing facts and knowledge. The book is organised as thirteen long form chapters and more than hundred short form entries in a list of thematic objects, tools and concepts that are critical for our understanding of information. Each long-form chapter discusses the role of information at an important point in time in the history, at a particular geographical setting. Written by an international team of experts, “Information: A Historical Companion” is a wide-ranging, deeply immersive and a large publication. In this episode of Bridging the Gaps I speak with Paul Duguid, a professor in the School of Information at the University of California, Berkeley and one of the editors of this book. We start our discussion by exploring the concept of “information age” and addressing the question: has every age been an information age or is this title unique to this present time. We then discuss the significance of viewing history through the lens of information and viewing information through the lens of history. We also discuss our over reliance on information in the present time and the impact of increased volume and velocity of misinformation and disinformation on society. Professor Paul Duguid then discusses few entries in the list of thematic objects, concepts and tools. This has been a fascinating discussion, particularly for those who are keen to study our obsession with an informed existence.

Neural mechanisms in the human brain that are responsible for generating and keeping track of plans, and influencing a cascade of brain states that can link our goals with the correct actions are known as Cognitive Control. These mechanisms and processes enable us to transform plans and goals into actions. Cognitive Control, also known as Executive Control inhibits automatic responses and supports flexible, adaptive responses and enables sophisticated actions to achieve desired goals. From making a cup of coffee to buying a house, from planning a trip to a shopping mall to outlining a career path, humans are uniquely able to execute necessary actions. How do we do it? In his book “On Task: How Our Brain Gets Things Done”, cognitive neuroscientist David Badre presents the first authoritative introduction to the neuroscience of Cognitive Control. In this episode of Bridging the Gaps I speak with Professor David Badre to discuss this astonishing phenomenon, these fascinating mechanisms that have profound impact on our well-being. David Badre is professor of cognitive, linguistic, and psychological sciences at Brown University, where he is also on the faculty of the Carney Institute for Brain Science. He and his lab have made pioneering contributions to the neuroscience of Cognitive Control and Executive Function. I open our discussion by asking professor Badre why the scale of Cognitive Control activities is very large in the human brain as compared to all other animals. We discuss the effectiveness of Cognitive Control which is unique to the human brain. These days it is widely accepted that the prefrontal cortex is crucial for our highest mental functions, including cognitive control. But it took us a while to understand this. Professor Bare discusses the research on “the puzzle of the frontal lobe” that informs us that the prefrontal cortex is crucial for our highest mental functions. Cognitive control is about transforming knowledge into actions; so before actions can happen, the knowledge must exist. Professor Badre explains our present understanding of how the brain acquires knowledge through learning and how acquired knowledge is retained in the memory. Professor Badre explains how the brain aims to balance stability and flexibility in general and how it aims to balance cost and reward during the information retrieval process. We also touch upon fascinating research questions that professor Badre and his colleagues are presently working on in BadreLab.

Philosophical reflection on technology is not new, it is about as old as philosophy itself. However, as the impact of technology on everyday human life and on society keeps increasing, and new and emerging technologies permeate nearly every aspect of our daily lives, it is crucial that human-technology relationships are studied extensively and understood thoroughly. In this episode of Bridging the Gaps, I speak with philosopher Professor Peter-Paul Verbeek who suggests that human-technology relationships should be studied by focusing on how technologies mediate our actions and our perceptions of the world. Peter-Paul Verbeek is Distinguished Professor of Philosophy of Technology at the Department of Philosophy of the University of Twente. He is chair of the Philosophy of Human-Technology Relations research group and co-director of the DesignLab of the University of Twente. He is also honorary professor of Techno-Anthropology at Aalborg University, Denmark and is chairperson of the UNESCO World Commission on the Ethics of Science and Technology (COMEST). His research focuses on the philosophy of human-technology relations, and aims to contribute to philosophical theory, ethical reflection, and practices of design and innovation. I open this discussion by asking Professor Verbeek why humans are usually worried about new technologies. This is not a new phenomenon; even in ancient Greek, philosophers expressed their concerns about the emerging technologies of their time. We see similar concerns expressed at the time of the invention of the printing press. And now we see similar views being expressed by technologies such as Artificial Intelligence and Robotics. We discuss in detail philosophy of technology, technology ethics, ethics from with-in and the challenges posed by powerful and intelligent technologies of the future.

Ignorance, denials and negations have always been part of human experience. In this post-truth, post-industrial world, we often feel overwhelmed by the information and misinformation overload. Although we claim to live in an information age, consciously or unconsciously, actively or passively more and more we are choosing to ignore, deny and negate facts and valid opinions. In this episode of Bridging the Gaps, I speak with philosopher and sociologist Professor Renata Salecl and we this discuss this “passion for ignorance”. In her recent book “A Passion for Ignorance: What We Choose Not to Know and Why” Renata Salecl explores how the passion for ignorance plays out in many different aspects of life today. Renata Salecl is professor at the School of Law at Birkbeck College, University of London and senior researcher at the Institute of Criminology at the Faculty of Law in Ljubljana, Slovenia. I open our discussion by asking Professor Salecl to unpack and explain various faces of ignorance that she outlines at the start of the book. We discuss the transformation of the knowledge economy to ignorance economy as she reports in the book. This book is organised very well; most chapters in the book start by outlining some kind of ignorance, this could be an active or passive ignorance, conscious or unconscious ignorance, and then Salecl discusses underlying reasons and possible impact of these denials and negations. In this discussion we touch upon a variety of denials and negations and forms of ignorance. We start with an important form of negation which is “choosing to ignore scientific evidence”. We also discuss the emergence of new forms of denials and ignorance in this age of Big Data. Drawing on philosophy, social and psychoanalytic theory, popular culture, and her own experience, Salecl explains that ignorance is a complex phenomenon that can, on occasion, benefit individuals and society as a whole.
