During sleep some areas of the brain can be more active than during the waking state - laying down memory and the processing of information. So the information coming in throughout the day is processed off-line while you sleep. Sleep supports cognitive ability, memory enhancement, and our ability to come up with innovative solutions to complex problems.

Infographics expert Manuel Lima talks here about the thousand-year history of mapping data — from languages to dynasties — using trees of information. He tells the fascinating history of visualizations, and the urge to map what we know. He talks about networks and the way we use them to explain decentralization, interconnectedness, interdependence. He sees this new way of thinking as critical for us in solving many of the problems we are facing nowadays. The diagrams and pictures are worth a look, just for themselves.
