<P> Among the 22 scientific disciplines listed in the Thomson Reuters Essential Science Indicators Citation Thresholds ( thus excluding non-science academics ) , physics has the second most citations after space science . During the period January 1 , 2000 -- February 28 , 2010 , a physicist had to receive 2073 citations to be among the most cited 1 % of physicists in the world . The threshold for space science is the highest ( 2236 citations ) , and physics is followed by clinical medicine ( 1390 ) and molecular biology & genetics ( 1229 ) . Most disciplines , such as environment / ecology ( 390 ) , have fewer scientists , fewer papers , and fewer citations . Therefore , these disciplines have lower citation thresholds in the Essential Science Indicators , with the lowest citation thresholds observed in social sciences ( 154 ) , computer science ( 149 ) , and multidisciplinary sciences ( 147 ) . </P>
