Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
Portal:Chemistry
The chemistry portal Featured article This element occurs in numerous minerals with the main sources being rutile and ilmenite, which are widely distributed over the Earth. There are two allotropic forms and five naturally occurring isotopes of this element; Ti-46 through Ti-50 with Ti-48 being the most abundant (73.8%). One of titanium's most notable characteristics is that it is as strong as steel but is only 60% its weight. Titanium's properties are chemically and physically similar to zirconium. Selected picture Copper(II) sulfate is one of the most familiar compounds of copper. It also occurs naturally as the mineral chalcanthite. It is commonly used in schools for growing crystals. The pictured substance is the pentahydrate form. Categories
History and Philosophy of Chemistry Many chemists have an interest in the history of chemistry. Those with philosophical interests will be interested that the philosophy of chemistry has quite recently developed along a path somewhat different from the general philosophy of science. Other articles that might interest you are: There is a Wikipedia Project on the History of Science and a portal for the philosophy of science. Chemistry Resources Wikipedia:WikiProject Chemicals/Data is a collection of links and references that are useful for chemistry-related works. This includes free online chemical databases, publications, patents, computer programs, and various tools. Science is Fun University of Wisconsin–Madison Chemistry Professor Bassam Z. Shakhashiri, shares the fun of science. unit-conversion.info A good place to figure out what equals what.

The Element Song A goofy little song about all of the elements. Selected biographyYuan Tseh Lee (born 1936) is a Taiwanese chemist, and the first Taiwanese-born Nobel Prize laureate. Along with John Charles Polanyi and Dudley R. Herschbach, he received the 1986 Nobel Prize in Chemistry "for their contributions to the dynamics of chemical elementary processes." Lee's particular work was on crossed molecular beams, to further its use in general reactions, a method for the study of important reactions for relatively large molecules. Since 1994, Lee has been the President of the Academia Sinica of the Republic of China.
