World's smallest reproduction of a printed book requires electron microscope to read
A nano book created at Simon Fraser University is officially the world's smallest reproduction of a printed book. Teeny Ted from Turnip Town, written by Malcolm Douglas Chaplin and published by Robert Chaplin, has made it into that collection of minutia known as Guinness World Records.
The book is made of 30 microtablets etched out of crystalline silicon with a focused gallium ion beam, and measures 0.07 millimetres by 0.10 millimetres. It's valued at $15,000, but you can't even read it without the help of a scanning electron microscope.
