Archives of programs and data for physics
This archive provides public-domain programs and data for physics research.
About Archives of programs and data for physics
The site is an archive of public-domain programs and data for physics. It hosts physics calculation programs, other programs intended to help with computer work, physical constants, and experimental or theoretical data such as cross sections, rate constants, and swarm parameters. The material is mainly oriented toward plasma physics, numerical methods, and experimental data processing, with directories for programs, data, texts, and education.
Programs are primarily for IBM PC-compatible computers; programs without graphic units may run on other computers, but graphic parts would need reprogramming. Use is for noncommercial purposes with a copyright statement; other uses require contacting the author. Some files, including all .cs files and education texts, are in Czech.
Key features
- Public-domain physics calculation programs and supporting computer programs
- Physical constants, cross sections, rate constants and swarm parameters
- Directories for programs, data, texts and educational materials
- Index text files describe the content of each directory
- Programs mainly for IBM PC-compatible computers; non-graphic programs may work elsewhere
- Compressed .lzh and .Z files with lha, compress, uncompress and crlf tools
Best for: Researchers, educators, and students working in plasma physics, numerical methods, or experimental data processing who need public-domain physics programs and data.

Archives of programs and data for physics FAQ
What kinds of programs and data are in the archive?
It contains public-domain programs for physics calculations and other computer programs, plus physical constants and experimental or theoretical data such as cross sections, rate constants, and swarm parameters.
Can I copy or redistribute the programs and data?
They can be used for noncommercial purposes, including copying and further distribution, if copyright is stated. Other uses require contacting the author.
What compression and file formats are used?
.lzh files are compressed with lha; .Z files use compress and can be decompressed with uncompress on UNIX or uncomp on MS-DOS. The crlf program corrects line endings for MS-DOS, and unz.bat can combine these actions.
