How did humans figure out how to record and play back sound? How does a record groove contain an infinity of sound, and how does the speaker play it? Find out in this episode! Also: a long discussion about the hideously awful “Star Wars Holiday Special”, Mark’s backyard “Game of Thrones” viewings, why can’t we send nuclear waste into space?, Tickle deodorant, broke and forgotten inventors, tin can phones and loneliness, and how to become a “Specialist in the Sonic Acoustics of Ancient Spaces.” Thanks for listening!
