Impact factors for physics journals are primarily calculated based on citation counts, though other metrics also contribute to the overall score. The calculation methods can be explored further through resources like "ISI Journal Impact Factors" or "Journal Performance Indicators." The impact factors vary significantly across different areas of physics, including Applied Physics, Atomic, Molecular & Chemical Physics, Condensed Matter, and others. For instance, in 2002, the top-ranked journal in Applied Physics was "Mat Sci Eng R" with an impact factor of 11.893, while "Adv Phys" led in Condensed Matter with 13.952. There is a notable distinction between what the physics community considers "high impact" and the ISI's algorithmic assessment, which can lead to discrepancies in rankings. The discussion also touches on the persistence of researchers in seeking answers to these ranking questions, highlighting the ongoing interest in journal performance metrics within the academic community.
