← Dimensions: a walk through mathematics

Season 1

9 episodes · 2008

Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed!

  1. 1Dimension Two

    18 Jul 2008 · 15 min

    Hipparchus explains how two numbers can describe the position of a point on a sphere. He then explains stereographic projection: how can one draw a picture of the Earth on a piece of paper?

  2. 2Dimension Three

    25 Jul 2008 · 15 min

    M. C. Escher tells the adventures of two-dimensional creatures who are trying to imagine three-dimensional objects.

  3. 3The fourth dimension (1)

    01 Aug 2008 · 15 min

    Mathematician Ludwig Schläfli talks to us about objects in the fourth dimension and shows us a procession of regular polyhedra in dimension 4, strange objects with 24, 120 and even 600 faces!

  4. 4The fourth dimension (2)

  5. 5Complex Numbers (1)

    15 Aug 2008 · 15 min

    Mathematician Adrien Douady explains complex numbers. The square root of negative numbers is explained in simple terms. Transforming the plane, deforming pictures, creating fractal images.
