Number 17 (Story #4), January 17, 1991 by Phillip F. Schewe and Ben Stein PHYSICS HAD THE LOWEST "UNCITEDNESS" of all the sciences. A study conducted by the Institute for Scientific Information showed that 36.7% of all physics papers in journals covered by ISI's survey did not receive a single citation in the five years after publication, which was better than for chemistry (38.8%), biology (41.3%) and various other sciences. The rate for engineering papers was 72.3%. Among certain physics subdisciplines, the uncitedness fraction was 9.2% for atomic, molecular, and chemical physics, 16.7% for particle physics, 19.1% for condensed matter physics, 40.1% for acoustics, and 49.1% for optics.
