Cutting Edge:

Sometimes overlooked in the Sturm und Drang about Google Book Search is any consideration of the mechanics of economically scanning the books in the first place, but a patent awarded to Google gives insight into how the search behemoth accomplishes the task.

In short, Google has come up with a system that uses two cameras and infrared light to automatically correct for the curvature of pages in a book. By constructing a 3D model of each page and then “de-warping” it afterward, Google can present flat-looking pages online without having to slice books up or mash them onto a flatbed scanner.

    darkness and ignorance and the impact it can have in our subconscious minds and also in our present circumstances carries with it long lasting effects even after it is gone it is our shadow. it carries with it the final destructive elements that shall destroy humankind the war on terrorism and the one that is currently being fought for in our present day society. there is a lot of talk going around that it is only in our minds and our present circumstances if they are to improve leaves with me the lasting impression that we cannot solve this problem alone. yes i do believe there is a police state and a war going on in our own frontyards but i think we can help with the right attitudes all of us can fight for and do what is right.
