Episode notes
Electric Fish Navigation
- Regina Barber, Anil Oza, and Elsa Chang discuss electric elephant-nose fish.
- These fish use weak electric signals to navigate murky African rivers.
Collective Electric Field
- Elephant-nose fish combine electric fields for collective sensing.
- This creates a larger electric field, enhancing predator detection.
Simplifying Rhythms
- Humans tend to simplify complex rhythms, imposing order on randomness.
- This varies across cultures but shows a universal bias toward simpler rhythms.
