My standby is <a href="http://www.webelements.com/">Web Elements</a>, a site that seems to have been around forever.</p> <p>I recently happened onto Jorge Goncalves' <a href="http://pontotriplo.org/triplepoint/">Triple Point</a>, which summarizes the <a href="http://pontotriplo.org/triplepoint/2007/05/the_best_55_online_periodic_tables.html">best 55 online periodic tables</a>. Although some of the links are broken, there's plenty to choose from if Web Elements doesn't do the job.</p> <p>The various forms of elemental periodic tables are in many ways the ultimate chemical information systems. They summarize what's already known and even after a century still light the way to new areas of discovery. Periodic tables demonstrate, like perhaps nothing else in chemistry, the power of organizing information.</p> <p><em>Image Credit: <a href="http://flickr.com/photos/bonfire2k4/">Mike Mertz</a></em></p> Mon, 06 Aug 2007 06:47:00 +0000 urn:uuid:462a9221-fe21-4df5-93bd-02240f68749b Rich Apodaca http://depth-first.com/articles/2007/08/06/the-best-55-online-periodic-tables Meta periodictable informationsystem
