Find the best way to go from place to other places in order to : deliver, put tunnels, put bridges, irrigation network, short means and more ecological.
Subjects:
- Geography: cruises on the sea, shipping container, putting bridges and tunnels (like the Hyperloop (underground loop of Elon Musk project), water network, real time trafic optimization (GPS, trafic jam ...)
- Economy: Goods or mail delivery for carriers, distribution centres, Hyperloop, modifying the public transport or the circulation (jams, pollution, accessibility, …), Optical fiber network.
- Mathematics: measures, geometry (GIS), scales, combinatorics, graph theory, optimization.
- Computer science: algorithmic, coding.
- Physics: surface tension, water properties, soap elasticity,
- Chemistry: soap molecules.
- Technology: models production.
- Life and Earth Science: Irrigation in agriculture, minimal surfaces in biology (DNA, cells, …).

The project addresses the problem of building a net connecting different places (travel, railways, short tunnels, irrigation pipes, …).
We ask to find the optimal (in space and time) and ecological solutions to do that.

Create a model of your neighborhood or the given area as it is illustrated in the images below.
Create a soap solution by dilution of some quantity of soap in a basin.
Put the model ine the soap basin and remove it. a soap film appears betwin the 2 layers of the model. This film will connect the different points on the map.
The length of the film is optimal since the soap has an elastic property and get always the minimal position. The solution is not unique.
Student can compare after that the minimal solution among the optmal solutions.
