Flight Physics: Understanding Air Pressure and Bernoulli's Principle

The video explores the human fascination with bird flight, highlighting Leonardo da Vinci's early sketches and Daniel Bernoulli's contributions to fluid dynamics. It explains Bernoulli's principle, which shows the inverse relationship between air velocity and pressure, and discusses the Wright brothers' first powered flight. The video also covers the basics of air pressure, its composition, and how it changes with altitude, affecting oxygen availability. Finally, it reviews key concepts and poses quiz questions to reinforce learning.

Which inventor is known for creating sketches related to bird flight and flying machines?
