Never mind that twisty compact fluorescent. The new energy-efficient way to light your home is with LEDs. An upcoming crop of bulbs draw 12 watts or less, edging out a typical fluorescent, and they have a more conventional shape, contain no mercury, and last at least 25,000 hours, three times as long.
Nikola Tesla, pioneering inventor, died penniless and unrecognized. We have previously mentioned his hipster cred, but it has taken until 2010, almost 70 years after his death, for the man and his achievements to be apotheosized in the medium of Drunk History.

Thomas Edison has been dethroned as the father of recorded sound. The New York Times is today reporting on a find by American audio historians in Paris of a 10-second recording etched on paper in 1860, seventeen years before Edison invented the phonograph. The device, called a phonautograph, captured the snippet of song by scratching marks onto a paper blackened by smoke. Its inventor, Édouard-Léon Scott de Martinville, was a typesetter who was interested in the written preservation of speech. The resulting document was never intended for playback.

The papers Einstein wrote in 1905 covered a broad swath—special relativity, electrodynamics, Brownian motion, light quanta. Churned out in less than a year, these ideas had lasting impact: scientists today still devote their lives to evaluating Einstein´s work on gravity, space and time. Einstein isn´t the only scientist, however, to pull off such compacted productivity. Newton, Galileo and others had their own superproductive 12-month stretches—but as far as we can tell, no post-Einstein scientist has managed one. Why? Read on.
