Osmium introduced commercially in 1902. After only a few years, osmium was replaced by the more stable metal tungsten. Tungsten has the highest melting point among all metals, and its use in light bulbs increases the luminous efficacy and life of incandescent lamps. The light bulb manufacturer Osram (founded in 1906, when three German companies, Auer-Gesellschaft, AEG and Siemens & Halske, combined their lamp production facilities) derived its name from the elements of osmium and Wolfram (the latter is German for tungsten). Like palladium, powdered osmium effectively absorbs hydrogen atoms. This could make osmium a potential candidate for a metal-hydride battery
Otherwise Known as Sheila the Great work with Sheila because of her fear of the water Judy Blume dedicated the book to her father and her mother. The post-2002 reprints of this book have some lines edited and a bit of new content added to update the technology use in it (for instance, record players are replaced with CD players, and the camp's copier keeps malfunctioning, which is why Sheila must use a mimeograph machine, whereas the original had them already still using their mimeograph machine and not having a copier yet).
