About the index

Find the turn in the conversation.

A simple question can take you a long way. Is water wet? Why do we cry? Is 100 better than 101?

On The Rest Is Science, Hannah Fry and Michael Stevens take familiar ideas and look at them so closely that they start to feel unrecognisable. Their deep dives follow one big question. Field Notes starts with unusual objects and listener questions. This index helps you find the bit you remember, and watch it from that moment.

How the index works

Search in your own words. The index brings back transcript passages with context and a link to the moment in the original recording. Check the recording when details matter. Captions can contain errors in wording and timing.

Who runs it

Epfolium runs this independent project. Hannah Fry, Michael Stevens and Goalhanger are unaffiliated with it. The index finds where a topic was discussed. It does not speak for them. For corrections or questions about source material, contact Epfolium.
