This chapter presents a mathematical (just arithmetic!) discussion of a photo album which contains every possible digital picture that has or will be taken and illustrates an essay from Omni Science Fiction Magazine (the Great Library of Alexandria in Egypt was destroyed thousands of years ago, and we can only speculate today about what fabulous intellectual treasures were lost forever. But are they really lost? Is there some way that modern science could reconstruct the Library? The amazing answer is: In theory—MAYBE!).
