This map of physics is based on research-front data for the six-year period
ending in August 2009. The map shows the major fields of physics linked
together in a network based on the same principles as our research-front maps
showing highly cited papers. In the case of a field
map, we first identify all research fronts in Essential Science IndicatorsSM
Reuters which were assigned to the Physics category based on journal.
Then the linkage between fronts is computed based on how often they are
co-cited—that is, the frequency that current papers cite the two fronts jointly.
A clustering process then groups fronts into larger aggregates. Thus, each
circle in the map represents a group, or cluster, of research fronts on a broad
topic in physics. Some of these broad topics bring in literature from other
fields, such as computer science, chemistry, and materials science, which are
shown in the descriptions below the map. Hot fields containing concentrations of
recent highly cited papers are shown in yellow.
Annotations may have been added to this map which represent the
main research themes. These appear as labels attached to specific regions on the
Additional information about Research Fronts.
