Can we store summer’s heat to warm our homes in winter? Could humans perceive a fourth dimension? And why does light bend around gravity even though it has no mass?

Small questions from YOU which open doors to enormous worlds.

In this episode of Field Notes, Hannah Fry and Michael Stevens discuss underground heat batteries in Canada and Einstein’s thought experiments, from how the universe hides its secrets and how we uncover them.

Later, Michael presents a story which leads to an exploration of human behaviour, the experiments that reveal how authority influences our actions and why ordinary people can be pushed to act against what they say their values really are.

Welcome to The Rest Is Science: Field Notes. Every Thursday, Hannah and Michael share the science behind the world around us from the surprising to the unsettling and show how it shapes both the universe and ourselves.
