I recently listened to the episode on The Antikythera Mechanism and found it quite fun - https://www.bbc.co.uk/programmes/m0024x0g
Also, I wanted to mention something interesting - back when LLM-driven applications were just emerging, someone posted on Hacker News about how they categorized In Our Time episodes using the Dewey Decimal System with LLMs. Cool stuff - https://news.ycombinator.com/item?id=35073603
I love this one and actually posted the wiki to the The Antikythera Mechanism here (although didn't get traction unfortunately).
Shameless plug, but I have a podcast about the history of astronomy and did an hour long episode on the Antikythera Mechanism a little while back if you're interested in more detail: https://songofurania.com/episode/022
