The Museum’s science collection comprises mostly of photographs and documents relating to the history of Andrew Carnegie’s steel industries in America, the Carnegie-funded 60-inch telescope at Mount Wilson Observatory and the establishment of the Carnegie Institution for Science. The collection also contains some original artefacts such as early photographic equipment, a Line of Position computer and life-ring from the non-magnetic research vessel 'Carnegie' (1909-1929), a section of Carnegie steel rail rolled at the Edgar Thomson Steel Mill and a section of early T-shaped rail, the first ever to be manufactured at the mills of Sir John Guest in Wales (1831).
