Adam Walton interviewed Sir John Cadogan, President of the Learned Society of Wales, at his home for a lively and wide-ranging conversation. They look back over Sir John’s scientific career and discuss the importance of pure scientific research, his concerns about the effectiveness of renewable energy sources and why it’s taken so long for Wales to get its own Learned Society.
