Have your HP-41 right where it should be (in your hand) and unable to find the Internetz to look up nifty details of obscure chemical elements? Worry no more, the solution is here, the HP-41 program, “PERIOD”.
The program will display:
- Atomic number, Name and Symbol
- Group, Period and Block
- Atomic Weight
- Property (Alkali metal, Noble Gas, etc.)
- Type (Gas, Liquid, Solid or Unknown)
- Occurrence in nature (Primordial, From Decay, Synthetic)
- Melting Point, Boiling Point (in Kelvin)
- Year of discovery (“OLD” if known in ancient times)
- Electron Configuration
- Atomic Radius (empirical and calculated)
- Origin (Big Bang, Cosmic Rays, Small & Large Stars, Large Stars, Large Stars & Super Nova, Super Nova and Man Made)
You will find the ROM pages, program listing and element details on the Github project page. It is also included in the HP Museum’s “HP-41C Software Library“. Enjoy 🙂

The “Fuck It” people have made a Magic 8 Ball book of 108 answers that works as an oracle. Cute.
Hehe. Cute. It should have been 118 answers. though to keep with the OP.
Well, you an put them into your HP and program your very own oracle!
I could do just that 😀
