Today, the physicists' grail is more than ever the theory that will unify General Relativity and Quantum Mechanics, the infinitely large and the infinitely small, so these scientists construct new theories. The most publicised of these is “string” theory, which implies a ten or eleven-dimensional Universe! Apart from the three dimensions of space that we know, the other dimensions could be microscopic and rolled up, totally beyond our perception. In another approach, physicists are trying to…

Images have always been at the core of the scientific research. Thanks to computer processing and new visualization tools, they have acquired movement, volume and new resolutions, from the smallest atomic scale to cosmic dimensions. This film tries to give meaning to these 21 images and offers the keys to decode them.

Each year 600,000 hectares of forest around the Mediterranean basin are destroyed by fire. The breadth of this destruction calls for research into the development of forest fires. Scientists at the University of Corte have developed mathematical models from which computer simulations of fires can be constructed. The goal is to understand the propagation of the forest fire fronts in order to improve prevention and control of the fires. To make the simulation more accurate, large-scale tests…

Through the description of his researches, Claude Cohen-Tannoudji depicts his daily life as a physicist in a human-sized team.

On a circuit devoted to the motorcycle racers ' training, three men talk about the innovations concerning the two-wheeled vehicles, specifically stability and handiness matters, linked to the conception of suspension.

In Hamburg, the particle accelerator HERA is located under the city's soccer stadium. At each end of the accelerator two teams of 400 researchers face each other around the H1 and ZEUS detectors. The object of their rivalry is to unlock the secrets of the basic constituents of the atom and in particular to study proton structure.
