1500 - 1700 A.D. 1588 Agostino Ramelli's reading wheel Agostino Ramelli designed a "reading wheel", which allowed browsing through a large number of documents without moving from one spot to another. The device presented a large number of books - a small library - laid open on lecterns on a kind of ferry-wheel. It allowed skipping chapters and browsing through pages by turning the wheel to bring lectern after lectern before the eyes. Ramelli's reading wheel thus linked ideas and texts and reminds of today's browsing software used to navigate the World Wide Web. 1597 The first newspaper is printed in Europe.

Calculator Calculators are machines for automatically performing arithmetical operations and certain mathematical functions. Modern calculators are descendants of a digital arithmetic machine devised by Blaise Pascal in 1642. Later in the 17th century, Gottfried Wilhelm von Leibniz created a more advanced machine, and, especially in the late 19th century, inventors produced calculating machines that were smaller and smaller and less and less laborious to use.
