Around the year of [our Lord](jesus.md) 1450 a major technological leap known as the **Printing Revolution** occurred. Johannes Gutenberg, a German goldsmith, perfected the process of producing [books](book.md) in large quantities with the movable type press. This made books cheap to publish and buy and contributed to fast spread of [information](information.md) and better education. Around this time the **Great Wall of China** is being built.
They year 1492 marks the **discovery of America** by Christopher Columbus who sailed over the Atlantic Ocean, though he probably wasn't the first in history to do so, and it wasn't realized he sailed to America until after he died (he thought he sailed to India). This is sometimes taken to mark the **end of Middle Ages** and transition to **Renaissance**. This was a time of increased interest in rationality, science and art; Renaissance saw man as a potent creation of God, who is capable of creating on his own rather than being mere blind, obedient servant of God. Great many polymath lived at this time, most notably **[Leonardo da Vinci](da_vinci.md)** (probably [gay](gay.md)) who was an excellent painter, explored human anatomy and even subjects such as astronomy and engineering. On one hand Renaissance brought beautiful art and new technology, on the other hand it further shifted society toward capitalism and selfish thinking, human became more self centered, [egoistic](egoism.md) and art became even more a matter of business -- for example the great painters infamously hired lesser artists to make copies of their paintings which were then sold almost like consumer products.

In 1642 Blaise Pascal, a french mathematician/inventor/philosopher, invented *Pascaline*, a simple [mechanical](mechanical.md) calculator (however building on ideas dating back to antiquity), laying some very early foundations for automatic computation. (The [Pascal](pascal.md) programming language is named after him.) Shortly after Pascal another genius, Gottfried Wilhelm Leibniz, further developed some basic theory (related e.g. to [binary](binary.md) system and [algorithms](algorithm.md)) that would much later on evolve into computer science.
