TED-Ed: How do schools of fish swim in harmony? - Nathan S. Jacobs

The video explores the concept of emergence, where complex behaviors arise from simple elements. It uses examples like fish schooling, sand ripples, and snowflakes to illustrate how local interactions lead to emergent patterns. In the brain, neurons follow simple rules to create complex thought processes. Emergence doesn't require a leader; it happens when the right conditions are met, turning chaos into order.

What is the primary reason fish swim in schools?

• To find food more easily

• To conserve energy

• To enjoy each other's company

• To evade predators

What is a key characteristic of emergent systems?

• They require a central leader

• They are unpredictable

• They arise from simple local interactions

• They are always chaotic

How do neurons in the brain contribute to complex behaviors?

• By acting independently

• By exciting or inhibiting other neurons

• By following complex individual rules

• By forming static patterns

What happens when neurons are connected in a network?

• They form a simple circuit

• They create chaotic patterns

• They generate rhythmic patterns

• They become inactive

What is a common feature of emergent phenomena across different scales?

• They are unique to each system

• They follow the same basic rules

• They require a central control

• They are unpredictable

What is the role of inhibitory neurons in neural circuits?

• To activate other neurons

• To prevent any activity

• To create static patterns

• To remove inhibitory brakes

How do complex systems like cities and economies organize?

• By following emergent rules

• Through individual decisions

• By random chance

• Through central planning
