What your teachers (probably) never told you about the parabola, hyperbola, and ellipse

The video explores the concept of triangulation through a scavenger hunt, explaining how GPS works using satellites. It discusses the application of triangulation in earthquake detection and introduces hyperbolic navigation, highlighting its historical use in the LORAN system. The video also covers the properties of ellipses and their role in acoustics, as well as the practical applications of parabolas in technology and architecture.
