  My favourite Robert Stawell Ball article is "Further development of the relations between impulsive screws and instantaneous screws..."

  But all joking about impulsive screws aside, Ball was a fascinating man, and we're very lucky to have his photos at Library Towers:

  Ball was a very talented amateur photographer. His membership until 1911 of the Commissioners of Irish Lights inspection committee that circumnavigated the Irish coast each year gave him the opportunity to capture many splendid images, not only of lighthouses and other navigational facilities, but also of everyday life in the more remote coastal areas. Many of these photographs are held in the National Photographic Archive (NLI).
