Discovery Mondays - "Seeing the Universe in a different light"

This evening should shed a little more light on CERN! Come and discover the role played by light in the research performed at CERN or how physicists make use of it to gain a better understanding of particles and the history of our Universe.

Legend

The fibre-optic cables for the ALICE experiment.

Scientists will therefore be inviting you to discover light in all its guises through a series of interactive demonstrations and fun activities open to the whole family.

For example, you will be able to measure the speed of light with the help of a microwave oven and a bar of chocolate! You'll also find out how a camera or a telescope works. Children (aged between 8 and 10) will be able to make Newton's disc, an astonishing rainbow-coloured disc. The ALICE experiment will demonstrate to older participants how an electric signal produced following a collision between particles is first converted into a digital signal before being transmitted as a light signal to computers via a fibre-optic cable. In addition, a physicist from the experiment will present the crystals used to convert very high-energy particles into a blue light. Finally, you will be able to become better acquainted with the photo-electric effect, one of Einstein's most famous discoveries...

Come to this Discovery Monday and talk to some of the â€ﾜluminaries” in matters of light!

This Discovery Monday will be taking place as part of the World Year of Physics, as its theme is closely associated with one of the three articles published by Einstein in 1905, his â€ﾜannus mirabilis”.
