Help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time.Here’s a question for you dear listener. What’s the link between music and physics? What is the sound of physics? Today we're diving into a fascinating world where art, science, and music intersect. Joining us in our studio are two incredible individuals who have embarked on a journey that brings together the realms of sound, physics, and human emotion. Ain Bailey is a composer and the second Cavendish Arts Science Fellow. Cavendish Arts Science creates collective encounters between art and science that explore the world, our humanity and our place in the world. Ain’s practice explores sonic autobiographies and the constellation of sounds that form individual and community identities. Her compositions are often inspired by reflections on silence and absence, feminist activism and architectural acoustics. Dr Gemma Bale is an assistant professor of Medical Therapeutics at the University of Cambridge, and the head of the Neuro Optics Lab. Sitting at the junction of engineering and physics, her team develops new, non-invasive optical devices to monitor brain metabolism in areas which traditional brain monitoring can’t. Lately, she’s been exploring the relationship between music and dementia, and it was only a matter of time before she and Ain’s worlds collided, and a conversation sparked.  With Ain and Gemma, we talk about music of course, and how our brains react to it, exploring the unknown and bridging the gap between art and science.
