Codata Library: All physical constants

[mskocic]

GitHub - MilanSkocic/codata: Codata constants.

I would like to present a tiny library which contains physical constant from codata. The source code is auto-generated from a list of constants. The constants are interoperable with C and there is python wrapper with binaries on pypi. The library integrates with the Fortran Package Manager.

Thanks a lot. This is huge!

The CODATA were discussed previously in Physical constants

There are two other Fortran projects implementing these:

• GitHub - vmagnin/fundamental_constants: Fortran modules with the CODATA fundamental physical constants, generated by a Python script. (@vmagnin)
• Bob Apthorpe / stdlib-codata · GitLab (@arclight)

Any news about CODATA 2022? The constants should have been put online in May or June 2023. I guess the COVID years have slowed the work on the new values…

Usually the releases are associated with publications:

• codata 2018
• codata 2014
• codata 2010

I didn’t find any publication related to CODATA 2022.

@mskocic

I didn’t find any publication related to CODATA 2022.

Yes, they are late as they say on their page:

DEADLINE NOTICE
The 2022 CODATA adjustment of the fundamental constants is the next regularly scheduled adjustment. Data being used in this adjustment is required to have been discussed in a publication preprint or a publication prior to 31 December 2022.

I guess we just have to wait
