"The Joy of Science" with Professor Jim Al-Khalili

Can living scientifically empower us to navigate the complexities of today’s complex and unpredictable world? Can the joy of critical thinking and the effectiveness of the scientific method assist us in making better decisions? Can living a more rational life help us navigate modern life more confidently? In his new book “The Joy of Science” acclaimed physicist Jim Al-Khalili invites readers to engage with the world as scientists have been trained to do. He shows how the fundamental principles at the heart of scientific thinking, as well as the scientific process, are profoundly relevant to the perplexing times we live in and the tough choices we make. In this episode of Bridging the Gaps, I speak with professor Jim Al-Khalili and we thoroughly discuss very interesting and deeply intriguing ideas that he presents in this book. Professor Jim Al-Khalili is a theoretical physicist at the University of Surrey where he holds a Distinguished Chair in physics as well as a university chair in the public engagement in science. He is a prominent author, broadcaster and one of Britain’s best-known science communicators. I start our discussion with the question that how the discipline of science should be perceived. We acknowledge that there are many ways scientific work is carried out in many different disciplines. We discuss the issue of “relative truth” and how biases held by individuals impact their opinions and distort their view and lead them to their own version of truth. We explore how science deals with the issue of relative truth. We probe how the scientific method enables us to continue researching in the presence of uncertainty. We investigate the impact of misinformation and disinformation on the disciple and cause of science. We also touch upon how rational humans can become; can we think rationally only up to certain point. We discuss in detail how scientific information should be presented to policy makers that should enable and empower them to make better decisions and to make the right choices. Finally, I ask Professor Jim Al-Khalili to tell us about his research in the field of open quantum systems. This has been a fantastic discussion.

"Artificial Intelligence: A Guide for Thinking Humans" with Professor Melanie Mitchell

Recent developments in the field of Artificial Intelligence are fascinating as well as terrifying; there are extravagant promises as well as frustrating setbacks; there is great progress in narrowly focused AI applications, and there is lack of progress in the field of Artificial General Intelligence. In this episode of Bridging the Gaps I speak with professor Melanie Mitchell and we discuss the history, recent successes, huge expectations and emerging fears and frustrations in the field of Artificial Intelligence. We discuss fascinating and intriguing research that professor Melanie Mitchell discusses in her book "Artificial Intelligence: A Guide for Thinking Humans". Melanie Mitchell is a professor of complexity at the Santa Fe Institute in New Mexico. Her research focuses on genetic algorithms, conceptual abstraction, analogy-making and visual recognition in Artificial Intelligence Systems. Professor Mitchell originated the Santa Fe Institute's Complexity Explorer project, an online learning resource for complex systems. We begin our discussion by reviewing the history of this fascinating field and by discussing initial claims and hype that emerged at the start. We then discuss the transition from rule-based AI systems to machine learning approaches. We look into the successes of AI in narrowly defined task-based systems; we discuss the anomalies that emerge when the data is mildly changed. We then discuss the future development in this field and the challenges involved in making any meaningful progress towards Artificial General Intelligence and creating common sense in AI systems. The challenge of creating common sense seems similar to the challenge of finding and understanding dark matter in the field of physics, we discuss this. We look into the profound disconnect between the continuing hype and the actual achievements in AI, what the field has accomplished and how much further it has to go. We also discuss the approach of conceptual abstraction and incorporating analogy-making in AI systems. This has been a fascinating discussion about this ambitious and thought-provoking field.

The End of Astronauts, Robotic Space Missions and Our Future on Earth & Beyond with Prof Martin Rees

Human space exploration is challenging as well as fascinating. However, the excitement of space flight for astronauts comes at a high cost and is riddled with danger. As our robot explorers become more capable, governments and corporations must consider whether the ambition to send astronauts to the Moon and Mars is worth the cost and risk. In this episode of Bridging the Gaps, I speak with professor Martin Rees who is one of the authors of “The End of Astronauts: Why Robots Are the Future of Exploration”. The book makes the provocative argument for space exploration without astronauts and suggests that beyond low-Earth orbit, space exploration should proceed without humans. In this discussion, we also touch upon some intriguing points the professor Martin Rees discusses in one of his previous books “On the Future: Prospects for Humanity”. Martin Rees is an emeritus professor of Cosmology and Astrophysics at the University of Cambridge. He is the UK’s Astronomer Royal, a fellow of Trinity College and a co-founder of the Centre for the Study of Existential Risks at Cambridge University (CSER). We start by discussing our fascination with human space journeys and exploration. We discuss the title of the book “The End of Astronauts” which seems a bit strong. We then discuss the progress in developing better and smarter robots for robotic space exploration. We discuss the progress made by private space companies in reducing the cost for space missions. Professor Rees emphasise the point that space is hostile and difficult environment and we should avoid using terms as space tourism, instead you should call it space adventures. We then discuss the book “On the Future: Prospects for Humanity” and touch upon topics such as colonisations of Mars, post human era; genetic engineering and our future on earth and beyond.

"Spark: The Life of Electricity and the Electricity of Life" with Professor Timothy Jorgensen

When we think about electricity, we most often think of the energy that powers various devices and appliances around us, or perhaps we visualise the lightning-streaked clouds of a stormy sky. But there is more to electricity and “life at its essence is nothing if not electrical”. In this episode of Bridging the Gaps, I speak with Professor Timothy Jorgensen and we discuss his recent book “Spark: The Life of Electricity and the Electricity of Life ”. The book explains the science of electricity through the lenses of biology, medicine and history. It illustrates how our understanding of electricity and the neurological system evolved in parallel, using fascinating stories of scientists and personalities ranging from Benjamin Franklin to Elon Musk. It provides a fascinating look at electricity, how it works, and how it animates our lives from within and without. We start by discussing the earliest known experiences that humans had with electricity using amber. Amber was most likely the first material with which humans attempted to harness electricity, mostly for medical purposes. Romans used non-static electricity from specific types of fish. Moving on to Benjamin Franklin, we discuss how he attempted to harner the power of electricity and we discuss the earliest forms of devices to store electric charge. We then discuss experiments conducted by Luigi Galvani on dead frogs and by his nephew on dead humans using electricity. As interest in electricity grew, many so-called treatemnts for ailments such as headaches, for bad thoughts and even for sexual difficulties also emerged that were based on the use of electricity; we discuss few interesting examples of such treatments. We then move on to reviewing the cutting edge use of electricity in medical science and discussed medial implants, artificial limbs and deep stimulation technologies and proposed machine-brain interfaces. This has been a fascinating discussion.

Asking Better Questions for Problem Solving, Innovation and Effective Leadership with Hal Gregersen

Every problem or issue raises new questions, which must be correctly answered in order to address the problem or resolve the issue. What if we could get a better answer to our most troublesome problem—at work or at home—just by altering the question? If asking right questions is essential for creative problem solving and innovation, and for effective leadership, shouldn’t we know more about how to arrive at right questions? In his book “Questions Are the Answer: A Breakthrough Approach to Your Most Vexing Problems at Work and in Life” Hal Gregersen gives many examples of people who had used questions in specific ways to solve problems. He gives many examples of how managers have used questioning in a variety of ways to obtain better results and provides additional information sources on key topics for those who want to dig deeper. In this episode of Bridging the Gaps I speak with Hal Gregersen. Hal Gregersen is a senior lecturer in leadership and innovation at MIT Sloan School of Management. He is a former executive director of the MIT Leadership Center and a cofounder of the Innovator’s DNA consulting group. He is a prolific author and a motivational speaker, and has helped leaders around the world to create cultures of fearless inquiry and to transform their organizations into innovative powerhouses. He is one of the authors of “The Innovator's DNA: Mastering the Five Skills of Disruptive Innovators” a book cited by managers, creative problem-solvers and leaders around the world as a highly recommended read for anyone interested in innovation. I open the discussion by asking Hal Gregersen about the evolving and ever changing landscape of leadership. We then discuss catalytic and recursive questions. How to learn to ask the right questions is essential for creative problem solving; we discuss this. Although the primary focus of this discussion is on Gregersen’s book “Questions are Answer: A Breakthrough Approach to Your Most Vexing Problems at Work and in Life”, we do touch upon the book that he co-authored “The innovator's DNA: Mastering the five skills of disruptive innovators''. I ask him to outline, compare and rate these five skills of disruptive innovators. We then discuss how leadership should evolve in this age of “working from home”. Finally I ask him for tips and suggestions for our young listeners and for future leaders; what skills they should acquire so that they are ready to meet future challenges. This has been a fascinating and highly informative discussion.

On Public Communication of Science and Technology with Professor Bruce Lewenstein

From the museums of the fifteenth century, to the public lectures of Michael Faraday in the nineteenth century, and to various science fairs & festivals of the twenty-first century, public engagement of science has evolved immensely. Public engagement of science in this age of hyper connectivity is “a multidimensional and multi-directional activity”. In this episode of Bridging the Gaps I speak with professor Bruce Lewenstien, a widely-known authority on public communication of science and technology. Bruce Lewenstein is a professor of science communication at Cornell University. He has done extensive work on how science and technology are reported to the public and how the public understands complex and sometimes contested scientific issues. He studies and documents the ways that public communication of science is fundamental to the process of producing reliable knowledge about the natural world. We begin by discussing the “multidimensional” and “multidirectional” nature of science communication. We then focus on the evolution of science communication from the early days of science to present time. We touch upon the huge impact on the public understanding of science that few books published in the mid-twentieth century had. We discuss in detail documentaries such as “The Ascent of Man” and “Cosmos” and the emergence of the phenomenon of “celebrity scientists”. The effectiveness of science communication in the age of information overload and in the age of misinformation and disinformation is an important topic that we discuss. We then discuss the challenges faced by the process of science communication and the societal challenges that effective science communication can help us to deal with.

"Forgetting: The Benefits of Not Remembering" with Dr Scott Small

We all wish to have a better memory, yet there are times when it fails us. Until recently, most people, even memory scientists, believed that forgetting served no purpose. However, new research in psychology, neuroscience, medicine, and computer science paints a different picture. It informs us that forgetting is not a failure of our minds. It's not even a benign glitch. It is, in fact, good for us and, alongside memory, it is a required and a separate function for our minds. It benefits our cognitive and creative abilities, emotional well-being, and even our personal and societal health. It appears to be a shortcoming and a failure, but forgetting opens up our minds to making better decisions, it clears up our minds to experiencing joy and relationships. In this episode of Bridging the Gaps, I speak with Dr Scott Small who explains why forgetfulness is not only natural and normal, but also beneficial. We discuss research that he presents in his book “Forgetting: The Benefits of Not Remembering”. Dr Scott. Small is a physician specializing in aging and dementia and is a professor of neurology and psychiatry at Columbia University, where he is the director of the Alzheimer's Disease Research Center. We start by discussing the working of human memory. I then ask Dr Small to unpack the statement “forgetting something is not a failure of the remembering process; forgetting is an independent feature of the brain managed by the processes that are different from the processes in the brain that manage remembering”. I ask Dr Small to explain the term “normal forgetting”. We then discuss the impact of aging on the brain. We discuss in detail the cutting edge research on Alzheimer’s disease and regions of the brain where it attacks. We then discuss the possible treatment for Alzheimer’s disease. We also touch upon how to look after our brains as we age.

"Learning How to Learn": Techniques to Help You Learn with Dr Barbra Oakley (CLASSIC)

Humans have fundamental ability and cognitive resources to learn new concepts and acquire new skills and knowledge, although this may not seem natural to most of us at first. The key is to understand how the brain works so we can harness its potential by developing and adopting learning techniques that are effective and more rewarding. In this episode of Bridging the Gaps, I speak with Dr Barbara Oakley about “Learning how to learn”. Dr. Oakley encourages learners to recognize that everyone learns differently. Recognizing the benefits and drawbacks of various learning approaches depending on a learner’s natural brain functioning, she argues, is the first step in learning how to handle new information. Dr Barbara Oakley is a professor of Engineering at Oakland University in Rochester, Michigan. She is an inaugural “Innovation Instructor” at Coursera, an online course provider, where she co-taught one of the world’s most popular massive open online course “Learning How to Learn”. Her work focuses on the complex relationship between neuroscience and social behavior. She has written many books including “Learning How to Learn: How to Succeed in School Without Spending All Your Time Studying; A Guide for Kids and Teens”. Her book “Mindshift: Break Through Obstacles to Learning and Discover Your Hidden Potential” is also relevant to this discussion. We start the conversation by discussing Dr Oakley’s education and professional journey, which led to her developing interest in “Learning how to learn”. We then discussed our present understanding that how learning occurs in the brain and how the brain acquires new knowledge. Dr Oakley explains why it is important to understand the working and functioning of the brain for developing and adopting effective learning techniques. She then explains a number of effective techniques for effective learning such as when to focus and when to take a break, she discusses significance of practice and being persistent. Dr Oakley then discusses in detail the effectiveness of Pomodoro technique. We then discuss the future of MOOC (Massive Open Online Courses) and universities in the age of online teaching and learning. We also touch upon the possible impact of over-reliance on and excessive use of technology for online learning.

"The Self-Assembling Brain" and Quest for Improved AI with Professor Peter Robin Hiesinger

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: Building and Harnessing the Power of Quantum Machines with Prof. Andrea Morello

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.
