Lesson Summary:

In this lesson, we explore the concept of fibration and topology with a focus on the torus of revolution and families of circles on the torus. The torus is covered by four families of circles, each of which do not intersect each other. The Villarza theorem states that a plane that is tangent to the torus will cut it along two circles, and we can obtain four circles through each point on the torus. We also learn about hopped circles and the dupern cyclades, which are surfaces covered by four families of circles. Finally, we see how a simple rotation in the fourth dimension can switch the colors of the inner and outer faces of the torus.

    This video continues the series on further dimensions, complex numbers, and fibrations. The images produced by such geometry is truly remarkable. The torus and topology is discussed in depth, including rotations in four dimensions and families of circles on the torus, created by cross-sectional slices from planes. An intriguing video to watch.
