Dr Lyn Evans has spoken of his pride that Wales was involved in the discovery of what's believed to be the Higgs Boson particle.
Dr Evans from Aberdare was the project leader for research into Higgs Boson, which gives matter mass and and holds the physical fabric of the universe together.
Scientists have been looking for the Higgs since the 1960s, but the search began in earnest more than 20 years ago with early experiments at Cern in Europe and Fermilab in the US.
