Dimensions: A Walk Through Mathematics

[Yogesh योगि]

Dear teachers,


Dimensions is a French project that makes educational movies about
mathematics, focusing on spatial geometry. It has animations and the films are released under a Creative
Commons licence.

Download it athttp://www.dimensions-math.org/Dim_download_E.htm and
share to all.

The film is separated in nine chapters, which follow this plot:

Chapter 1: Dimension two explains Earth's coordinate system, and
introduces the stereographic projection.
Chapter 2: Dimension three discusses how two-dimensional beings
would imagine three-dimensional objects.
Chapters 3 and 4: The fourth dimension talk about four-dimensional
polytopes (polychora), projecting the regular ones stereographically
on the three-dimensional space.
Chapters 5 and 6: Complex numbers are about the square root of
negative numbers, transformations, and fractals.
Chapters 7 and 8: Fibration show what a fibration is. Complex
numbers are used again, and there are circles and tori rotating and
being transformed.
Chapter 9: Proof emphasizes the importance of proofs in
mathematics, and proves the circle-conservationess of the
stereographic projection as an example.
