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

Spark Book Review at Bridging the Gaps

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.

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

Forgetting: The Benefits of Not Remembering

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.
