Optics was significantly reformed by the developments in the medieval Islamic world, such as the beginnings of physical and physiological optics, and then significantly advanced in early modern Europe, where diffractive optics began. These earlier studies on optics are now known as "classical optics".
1861 – the first transcontinental telegraph system spans North America by connecting an existing network in the eastern United States to a small network in California by a link between Omaha and Carson City via Salt Lake City. The slower Pony Express system ceased operation a month later.
The history page on the Google Books website describes their initial vision for this project: "in a future world in which vast collections of books are digitized, people would use a 'web crawler' to index the books' content and analyze the connections between them, determining any given book's relevance and usefulness by tracking the number and ...
