On Saturday, skywatchers around the world were treated to views of the so-called "supermoon," the largest full moon of the year. On May 6, the moon approached within 357,000 km (222,000 mi) of Earth, in what is scientifically known as a perigee-syzygy of the Earth-Moon-Sun system (perigee: closest point of an elliptical orbit; syzygy: straight line made of three bodies in a gravitational system). Photographers across the globe set out to capture the event, and collected here are 24 of the most super images of this year's supermoon. [ 24 photos ] The full moon rises over the skyline of Lower Manhattan and One World Trade Center in New York, as seen from West Orange, New Jersey, on May 6, 2012. http://www.theatlantic.com/infocus/

Principles of War, by Carl von Clausewitz

http://www.clausewitz.com/readings/Principles/ by Christopher Bassford Before Clausewitz left Prussia in 1812 to join the Russian army and resist Napoleon, he prepared an essay on war to leave with the sixteen year-old Prussian Crown Prince Friedrich Wilhelm (later King Friedrich Wilhelm IV, r.1840-1858), whose military tutor he had become in 1810. This essay was called "The most important principles of the art of war to complete my course of instruction for his Royal Highness the Crown Prince" [" Die wichtigsten Grundsätze des Kriegführens zur Ergänzung meines Unterrichts bei Sr. Königlichen Hoheit dem Kronprinzen "]. This essay is usually referred to as the "Principles of War." It represented Clausewitz's theoretical development up to that point, translated into a form suitable for his young student.

Great explanations are unfortunately scarce, but UUorld makes them easier to achieve through interactive four-dimensional maps. Our solution has three simple parts: We think you'll find four-dimensional mapping delivers results because the medium exposes the spatial and temporal context inherent to nearly all data. http://uuorld.com/
