The first attempt to explore western South America was undertaken in 1522 by Pascual de Andagoya. The native South Americans he encountered told him about a gold-rich territory called Virú, which was on a river called Pirú (later corrupted to Perú) and from which they came. These reports were related by the Spanish-Inca mestizo writer Garcilaso de la Vega in his famous Comentarios Reales de los Incas (1609).

The Pacific Ocean is the largest of the Earth's oceanic divisions. Its name is derived from the Latin name Mare Pacificum, "peaceful sea", bestowed upon it by the Portuguese explorer Ferdinand Magellan. It extends from the Arctic in the north to Antarctica in the south, bounded by Asia and Australia in the west, and the Americas in the east. At 169.2 million square kilometres (65.3 million square miles) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46% of the Earth's water surface and about 32% of its total surface area, making it larger than all of the Earth's land area combined.[1] The equator subdivides it into the North Pacific Ocean and South Pacific Ocean. The Mariana Trench in the western North Pacific is the deepest point in the Pacific and in the world, reaching a depth of 10,911 metres (35,798 ft).[2]

The Zweihänder could be up to 180 cm (6 ft) long from the base of the pommel to the tip of the blade, with a 120–150 cm (4–5 ft) blade and 30–45 cm (1–1½ ft) hilt. The weight could range between 2 kg and 3.2 kg (4½–7 lb). However, a ceremonial Zweihänder, which was unsuitable for combat, could weigh up to 7 kg (16 lb). Some were shorter, though. Earlier versions, in particular, often had an overall length of about 150 cm (5 ft), weighing as little as 1½ kg (3 lb 5 oz).

In 1616, on the orders of the then pope, Paul V, Cardinal Bellarmine summoned Galileo Galilei, notified him of a forthcoming decree of the Congregation of the Index condemning the Copernican doctrine of the mobility of the Earth and the immobility of the Sun, and ordered him to abandon it.[2] Galileo agreed. When Galileo later complained of rumors to the effect that he had been forced to abjure and do penance, Bellarmine wrote out a certificate denying the rumors, stating that Galileo had merely been notified of the decree and informed that, as a consequence of it, the Copernican doctrine could not be "defended or held".[3] (In 1633 Galileo would again be called before the Inquisition in this matter.)

By the early 1500s, he realized that Ptolemyís system for calculating the positions of the planets was much too cumbersome.

Leonardo DaVinci the renaissance man and one of the most famous artists in the world was also an incredible inventor. This gallery is full of drawings made by Leonardo DaVinci of his ideas for inventions.

In contrast, the impact of Gutenberg's printing press in Europe was comparable to the development of writing, the invention of the alphabet or the Internet, as far as its effects on society. Just as writing did not replace speaking, printing did not achieve a position of total dominance. Handwritten manuscripts continued to be produced, and the different graphic modes of communication continued to influence each other
