With over 300 entries from the ancient abacus to X-ray diffraction, as represented by a ca. 1900 photo of an X- ray machine as well as the latest research into filmless x- ray systems, this tour of the history of scientific instruments in multiple disciplines provides context and a bibliography for each entry. Newer conceptions of "instrument" include organisms widely used in research: e.g. the mouse, drosophila, and E. coli. Bandw photographs and diagrams showcase more traditional instruments from The Science Museum, London, and the Smithsonian's National Museum of American History.
