VIDEO: Geometry Applications: Circles

Topic

Circles

Description

This video series, "Geometry Applications: Circles," delves into the mathematical and cultural significance of circular geometries through historical and architectural examples. The first segment introduces the geometry of circles, covering key concepts such as the center, radius, diameter, chords, and arcs, while emphasizing their applications in ancient structures like Pueblo Bonito and Stonehenge for tracking celestial events and designing ceremonial spaces. The second segment explores the Roman Colosseum's elliptical structure, explaining the differences between circles and ellipses, with a focus on terms like ellipse, foci, and perimeter, and demonstrates the Romans’ innovative use of circular arcs to approximate an ellipse in construction. The final segment highlights the Pantheon, using its oculus to illustrate chords, inscribed angles, and intercepted arcs, connecting geometric principles to light dynamics and their symbolic representation in architecture.
