24 de novembro de 2012 | N° 17263 ARTIGOSPerspectiva, por Aloyzio Achuti* Somos indivíduos naturalmente bastante isolados uns dos outros, embora profundamente interdependentes na conjuntura social. Não existimos, nem conseguimos subsistir sem os outros e sem ligações com o meio no qual vivemos. É um desafio da seleção natural testando-nos ao desvendar os caminhos da comunicação, e buscar o equilíbrio entre o individual e o coletivo.

The Psychology Of Tetris *Last week’s BBC Future column. The original is here. There’s a more melancholy and personal version of this column I could have written called ‘I lost years of my life to Sid Meier’s ‘Civiliation’, but since the game is now out on iphone I didn’t have time to write it.* *How the secret to the popular game’s success is that it takes advantage of the mind’s basic pleasure in tidying up and uses it against us.* Shapes fall from the sky, all you have to do is to control how they fall and fit within each other. A simple premise, but add an annoyingly addictive el... mais »

*The Library of Utopia* Google's ambitious book-scanning program is foundering in the courts. Now a Harvard-led group is launching its own sweeping effort to put our literary heritage online. Will the Ivy League succeed where Silicon Valley failed? - By Nicholas Carr on April 25, 2012 In his 1938 book *World Brain*, H.G. Wells imagined a time—not very distant, he believed—when every person on the planet would have easy access to "all that is thought or known."
