Answer: What is Physics and Astronomy Classification Scheme mean?

The Physics and Astronomy Classification Scheme (PACS) is a scheme developed in 1970 by the American Institute of Physics (AIP) for classifying scientific literature using a hierarchical set of codes. PACS has been used by over 160 international journals, including the Physical Review series since 1975. Since 2016, American Physical Society introduced the PhySH (Physics Subject Headings) system instead of PACS.
