Physics-constants library?

[Mirko Vukovic]

I did not find a library with physics constants on cliki or quicklisp.

There is one available from within GSLL, but loading GSLL just for physics constants is an overkill.

Are there any other ones?

I have one of my own (somewhat incomplete) that works for me, and I can clean it up and push it to quicklisp if nothing meaningful is out there.

I gathered a few constants in an old emacs lisp file:

Of course, one would have to keep track of the official best values.
Some source like: http://physics.nist.gov/cuu/index.html perhaps?

Wikipedia also has a lot of constants.

Thanks,

Ralph Schleicher sent me an email with his nist-physics-constants.lisp program with values from http://physics.nist.gov/cuu/Constants/Table/allascii.txt

I hope he will make it available to others via quicklisp.

I've refactored the code to make it future proove, i.e. each revision
of the CODATA recommended values is embedded in it's own package. That
way you can explicitly refer to an individual revision by adding the
package prefix. Default is to use the latest values. I've also added
doc strings and the functions return the relative standard uncertainty
as the third value.

The library is public available from
<https://github.com/SCR4/codata-recommended-values.git>
and I've also submitted an issue to add it to quicklisp.
