Mark Miodownik is the materials scientist and engineer whose new book is It’s a Gas: The Magnificent and Elusive Elements that Expand Our World. The book is an exploration of that most ethereal of material states – gas – that can be as light as a substance to make us laugh or hang as heavy as one of the roots of the carbon-fuelled climate crisis. Miodownik is Professor of Materials and Society at University College London and he is also Director of the Institute of Making. Joining him to discuss the book is Alex Wilkins, reporter for New Scientist. We are sponsored by Indeed. Go to Indeed.com/IS for £100 sponsored credit.
