For newcomers seeking information on physics and applied mathematics journals, understanding journal rankings, particularly impact factors, is essential. Impact factors reflect how often journals are cited relative to the number of papers they publish, indicating their prestige within the field. Prestigious journals include the Physical Review series and Nature, with the latter being a significant achievement for published articles. For those starting to read journal articles, Physics Today is recommended for its accessible content across various topics. Resources for finding journal impact factors include Science Gateway and In-Cites, which provide comprehensive rankings across disciplines.
