Friday math movie: Moebius Transformations Revealed

By Murray Bourne, 01 Dec 2007

This is cool.

According to this Wikipedia article, a Möbius (or in anglicised form, 'Moebius') Transformation is the result of performing...

a stereographic projection from a plane to a sphere, rotating and moving that sphere to a new arbitrary location and orientation, and performing a stereographic projection back to the plane.

The mathematics involves matrices, determinants, transformational geometry (translation, rotation, dilation), complex numbers, group theory, conic sections (parabola, ellipse, etc) and iterations.

Apart from all that, it is a nice visual piece with an appropriate soundtrack (a piano solo that I used to play, from Schumann's Kinderscenen, Op. 15, I) . The movie has been accessed almost a million times on YouTube.

Enjoy.

    Hi Maria and "th" - I'm glad that you enjoyed this math movie. It certainly presses a few buttons in us (artistic, mathematical, musical).

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
