All time best Math video ever. Moebius transformation visualized in higher dimension
Video produced by Douglas Arnold and Jonathan Rogness.
The video demonstrates the transformations in two dimensions but then backs away and adds a third-placing a sphere above the plane and shining light through it. As the sphere moves and rotates above the plane, suddenly all the transformations become linked, in a way that conveys visually in minutes what would otherwise take “pages of algebraic manipulations.
This video has been viewed more than a million times on YouTube, so it is not new, but every time I see it, I am fascinated. Going to higher dimensions and visualizing moebius transformation is just a bonus.
