Dave Pepler: Smelt

Dave Pepler’s latest book is about change. Systems, whether complex or simple, remain stable until an external influence causes the entire system to undergo a phase change: ice becomes water, water becomes steam. This phenomenon also applies to humans. One day we are stable and happy, the next we are shattered. One day we are healthy and strong, the next sick or spiritually broken. Smeltexplores this fascinating similarity found in phases in nature and in the human experience. Natasha Harmse talks to Pepler.
