How Do Cicadas Make Noise? (In Slow Motion) – Smarter Every Day 299
In this lesson, we explore how cicadas produce their distinctive sounds using a specialized structure called the tymbal, which operates similarly to a Snapple bottle cap. Through high-speed filming, we observe that the tymbal opens and closes in just six milliseconds, creating various frequencies amplified by the cicada’s hollow body. The lesson also highlights the cicada’s life cycle, their periodic emergence, and the unique anatomy that enables their loud calls, culminating in a deeper understanding of these fascinating insects.
Nature’s Incredible ROTATING MOTOR (It’s Electric!) – Smarter Every Day 300
The lesson explores the flagellar motor, a remarkable molecular mechanism found in organisms like sperm and bacteria, which enables their movement through a rotating whip-like structure called the flagellum. Powered by a gradient of hydrogen ions, this motor converts potential energy into kinetic energy, allowing bacteria to swim and navigate their environment through a process known as chemotaxis. Ongoing research aims to uncover the motor’s intricate structure and evolutionary origins, highlighting the complexity of biological systems and their implications for understanding life.
How Disc Golf Discs Are Made (MVP Manufacturing Tour) – Smarter Every Day 301
