Lyn Evans – nicknamed ‘Evans the Atom’ in the grand tradition of Welsh people going by their jobs because so many people share the same few names – was originally going to study chemistry. He eventually switched to physics because he found it easier! You may not have heard his name before, but you’ve almost certainly heard of the Large Hadron Collider (LHC), the largest particle collider in the world. Evans was the project leader of the LHC, a role that earned him a CBE among many other honours.
