North Sentinel : L'île sauvage dont on ne revient pas vivant

Pourtant, tout visiteur qui a tenté d’y pénétrer n’a pu goûter qu’aux flèches et aux lances de ses occupants. Car l’île est habitée par une tribu qui refuse tout contact avec le monde extérieur. Il s’agit en quelque sorte d’un des derniers coins encore immaculés par notre civilisation. Située dans le golfe du Bengale, l’île de North Sentinel a une superficie de 72 km² et est officiellement administrée par l’Inde depuis 1947. Toutefois, ce petit bout de terre est le territoire d’une tribu autochtone qui rejette tout contact avec la civilisation moderne. Leur hostilité vis-à-vis des étrangers n’est toutefois pas difficile à comprendre.

Fra Mauro’s Mappamundi « Landsat Science

Imagine a half a millennium earlier when only those who had traveled could describe distant lands. Imagine watching the hustle and bustle of merchants and sailors returning to the port of Venice. What stories could they tell to paint a portrait of our planet? Fra Mauro, a Venetian monk and cartographer from the mid-15th century, made it his life’s work to chart the course of merchants and travelers in order to create the most definitive map of the world. Accounts from travelers interviewed by the monk are found throughout the map as citations of integrity. 40 more maps that explain the world.

Maps seemed to be everywhere in 2013, a trend I like to think we encouraged along with August's 40 maps that explain the world.

Maps can be a remarkably powerful tool for understanding the world and how it works, but they show only what you ask them to. You might consider this, then, a collection of maps meant to inspire your inner map nerd. I've searched far and wide for maps that can reveal and surprise and inform in ways that the daily headlines might not, with a careful eye for sourcing and detail. I've included a link for more information on just about every one. Enjoy. 1. Data source: Oak Ridge National Laboratory, World Bank.

Volta do mar

The further south ships went, the wider off sailing required to return "Volta do mar", "volta do mar largo" or "volta do largo", (the phrase in Portuguese means literally turn of the sea but also return from the sea) is a navigational technique perfected by Portuguese navigators during the Age of Discovery in the late fifteenth century, using the dependable phenomenon of the great permanent wind wheel, the North Atlantic Gyre. This was a major step in the history of navigation, when an understanding of winds in the age of sail was crucial to success: the European sea empires would never have been established had the Europeans not figured out how the trade winds worked.

Colonial Settlements That Failed: Photos. Before there was the success of Jamestown, there was the famous failure at Roanoke.

Colonial Settlements That Failed: Photos

Dispatched by Sir Walter Raleigh in 1587, a group of 150 colonists attempted to settle Roanoke Island. It was the second attempt after an earlier expedition to the same island by Raleigh failed. The new group of colonists would be led by John White, who was a friend of Raleigh and had been on the first trip to Roanoke. For the second expedition, rather than sticking with a male-exclusive group as was the case with the first, White brought over entire families, including his daughter, who would bear a child on the expedition. The colonists grew to realize that Roanoke Island could not sustain them over the long term, so White returned to England to bring back supplies, leaving the colonists and his daughter and granddaughter. As a result of conflict with the Spanish, White would not be able to return to Roanoke for three years.
