The Code Fractal geometry in nature and digital animation
Marcus du Sautoy describes how fractal geometry can be used to describe natural objects, and how it is used in digital animation. Trees use the simple rule of trying to maximize surface area, and this is something that can be simulated mathematically to give a very realistic result. Mandelbrot explored this fractal property of infinite complexity in his work, which ...

The Code Hexagons in the natural world
Marcus du Sautoy visits a beekeeper and explores how bees create their honeycombs. If they are going to tessellate they have a limited number of regular polygons they could choose from, but the hexagon is the most efficient – giving the maximum storage area for the least amount of wax. In fact, the bees do not create hexagons, but circular ...

Bitesize Space Science Gravity on Earth and in space
Jon Chase explains that the mass of an object is constant but its weight depends on the gravitational force. This force is higher on more massive planets and he would weigh more on Jupiter than on Earth. He uses a fairground ride to simulate the feeling of lower and higher gravitational forces. He explains that gravity is the force that ...
