For $20,000 US, you can lay claim to a limited edition of the World's Smallest Book. It measures less than 0.1 millimetres square! It was created with laser beam etchings on a silicon crystal (nanotechnology).
Implications - This brilliant innovation was created by a group of Canadian physicists and only has 30 "pages" (which are actually slices of silicon crystal). If you have prescription glasses, I'm sorry to say that they just won't cut it for this teeny tiny book. You're going to need something a whole lot stronger in order to read the text on these pages. Perhaps you should think about investing in a microscope?
