Cosmic Rectangle

September 10, 2008

I am delighted that a fellow maths educator is about to run a course on Maths and Art for gifted and talented year 9’s and even more delighted that a session will be devoted to the golden rectangle. It is an excuse for me to make my first origami maths video.

which is show an origami method of making a rectangle with the ratio 1:\frac{\sqrt{5}-1}{2}

Hypercube flickbooks

January 8, 2009

I have been tidying up recently and stumbled across this movie of a flickbook showing the “growth” of:
a point to a line (0D to 1D),
a line to a square (1D to 2D)
a square to a cube (2D to 3D)
and from a cube to a hypercube (3D to 4D).

Not much else to add, it does what it says on the tin!
