From: Josef 'Jupp' Schugt Date: 2003-03-11T09:19:26+09:00 Subject: [ANN] PSE as Ruby module and an RAA question Hi! Announcement - ------------ At http://members.lycos.nl/jupp/linux/soft/ruby/Periodic.html you can find Peridic.rb Periodic.rb is a Ruby module that provides information about all chemical elements as a single constant table named Periodic::Table. The database is taken from Gperiodic that is released under GPL. The character set used for the table is ISO 8859-1. Information that is not available is encoded as nil. Periodic::Table[0] provides descriptions of the table's columns (listed on the page), whereas Periodic::Table[1] through Periodic::Table[118] provide information about H (Hydrogen) through Uuo (Ununoctium) the index being the element's atomic number. RAA question - ------------ RAA seemingly has no Chemistry section. Periodic.rb is rather chemistry-oriented (it e.g. has no information about radioactive decay channels or isotopes but oxidation levels) so that it does not nicely fit in the Physics section. Still I would recommend *not* adding such a section but rather renaming the Physics section into Physics/Chemistry or Chemistry/Physics (because there are not only physics and chemistry but also physical chemistry or chemical physics). What do others people think about that? oyasumi-nasai Josef 'Jupp' Schugt http://jupp.tux.nu/
