The video explores why a circle is divided into 360 degrees, tracing its origins to the Babylonian base 60 system and the properties of a hexagon. It highlights the limitations of using degrees in higher mathematics, particularly in calculus, where real numbers are essential. The video introduces radians as a more effective way to measure angles, eliminating the complications associated with degrees.
