Ivy's Plant Shop How does water get from the roots to the leaves of a plant? New
This video explores how water is transported from the roots, through the tubes in the stem, to the tip of the plant. The process is demonstrated with an experiment. White carnations are placed in water with different colour dyes in them. Eventually the petals adopt the colour of the dyes, thus highlighting the process.

The Code Fractal geometry in nature and digital animation New
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 Normal distribution in fish populations New
Marcus du Sautoy examines a sample of dover sole from a day's catch, and by measuring the weight of this small number of fish, explores how the bell-curve of the Normal Distribution allows us to predict what the largest fish in the population is likely to weigh, even without catching it. The calculations are not shown in full detail, but ...

The Code Imaginary numbers at use in the real world New
Starting with the logical roots of arithmetic with negative numbers, Marcus du Sautoy explains how mathematicians created imaginary numbers by ‘imagining’ the square root of -1. Though imaginary in nature, he then explores how this abstract mathematical idea has become vital to air traffic control systems. Teacher notes: Use as an enrichment and extension clip during a series of lessons ...

The Code Using patterns in Google searches to predict flu outbreaks New
Marcus du Sautoy explores how internet searches are building up a huge database of linked information which can then be mined for patterns. Visiting Google’s offices, he sees this at work and reveals just how closely Google can predict flu outbreaks, even before hospitals have begun to need to respond to them. Flu kills hundreds of thousands each year, but ...

The Code Hexagons in the natural world New
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 ...
