The first proposal for the World Wide Web (WWW) was made at CERN by Tim Berners-Lee in 1989, and further refined by him and Robert Cailliau in 1990.

Antimatter – or the lack of it – remains one of the biggest mysteries of science. Matter and its counterpart are identical except for opposite charge, and they annihilate when they meet. At the Big Bang, matter and antimatter should have been produced in equal amounts. However, we know that our world is made up of matter: antimatter seems to have disappeared. To find out what has happened to it, scientists employ a range of methods to investigate whether a tiny difference in the properties of matter and antimatter could point towards an explanation.

CERN – European Organization for Nuclear Research is the world’s leading laboratory for particle physics. It has its headquarters in Geneva.
