Martmatics is a project to show how Mathematics and Art have been related to each other throughout history and how they are still linked today. There are many bonds and the authors have chosen the most attractive and significant ones. You will find a brochure and also an activity book with excercices to accompany the examples from the brochure.

The Art Gallery problem is a classic problem in Computational Geometry: Given an art gallery (a polygon), how many stationary guards do you need to guard it? We show practical applications of this problem and how it can be solved.

C. F. Gauss (1777-1855) showed that it is impossible to preserve all ratios of distances when drawing a planar map of a region of the Earth. But do we need to sacrifice everything?

Have you already remarked that the middle of the day (or solar noon) is not always at the same time on your watch? The sunset is sooner on December 10 than at the winter solstice. If you observe the Sun at noon every day, then its position draws a figure eight curve, called analemma, with endpoints at the winter and summer solstices.

From the inner core to the surface the Earth temperature decreases. This induces convection movements in the Earth’s mantle. The warmer magma moves closer to the surface where it cools down. It then sinks inside the mantle and a new cycle is started. This induces movements of the rigid tectonic plates at the surface, and shears.

Telecommunications, navigation, meterorology, etc., but also cell phones, GPS, Internet, provide numerous reasons to install satellites orbiting around the Earth. For this purpose, mathematicians select and optimise trajectories and orbits of spacecrafts with more and sophisticated techniques.

The study of the diffusion of liquids in the soil, also called percolation, allows scientists measuring how water is diffused in the soil, how fast aquifers refill, and to understanding the diffusion of gas, petrol and pollutants in the soil.
It is the English mathematician J. M. Hammersley who, in 1965, highlighted that diffusion and percolation also occur in telecommunication networks, the spreading of epidemics, propagation of fires, and the phase transition from water to ice.
In Tamilnadu, one would find a finest drawn and artistic drawing decorating every house at the front entrance.
These drawings are not just merely a decoration, but it has lot more significance to this practice.
During festival seasons and on any auspicious functions, the drawing is drawn still larger even extending up to the street! A classic example can be noted from these, a woman’s creative at its best, talent to make it an even more attractive.
A kolam is a geometrical drawing composed of curved loops drawn around a grid pattern of dots. It is sometimes called Rangoli and can be very elaborate and colorful.
Kolams originated about 2500 BC in the Indus Valley Civilization and are believed to help bring wealth and prosperity to the home or business.
Kolams are thought to bestow prosperity to homes.
Every morning in Tamil Nadu, millions of women draw kolams on the ground with white rice powder
