Atomic Test Effects in the Nevada Test Site Region Thirty-one atomic fission weapons, weapon prototypes, or experimental devices were fired in Nevada from January 1951 to January 1955. All were relatively small in explosive power. They ranged from less than one kiloton up to considerably less than 100 kilotons. (A kiloton is equal to 1,000 tons of TNT.) The forces released by test detonations in Nevada are very small compared to the tremendous forces released by the large fission and hydrogen weapons tested in the Pacific. Listen: Samuel L. Jackson narrates "Go the Fuck to Sleep" Author Adam Mansbach, after repeated struggles to get his two-year-old daughter to fall asleep, once sent out a jokey Facebook post reading: "Look out for my forthcoming children's book, 'Go the Fuck to Sleep.'" The one-liner amused many of his Facebook friends, and the next thing you know, Mansbach had assembled some verses, and bootleg PDF copies of the profanity-laced opus were suddenly going viral. The thirty-two-page Go the Fuck to Sleep was picked up by a small Brooklyn publishing house, and even reached number one on Amazon's bestseller list ahead of memoirs by Tina Fey and Steven Tyler, well before its official publication date, which was yesterday.

A TED Talk by LearnVest: 5 Financial Rules to Live By Last week, LearnVest CEO and Founder Alexa von Tobel visited the New York Stock Exchange to deliver a TEDx speech about personal finance. She told the story of one (hypothetical) girl–and the five financial principles that will shape her life. Like most of us, “Jessica” never took a single personal finance class in college, or ever, for that matter. 15 Amazing Animated Short films We all love short animated films, but creating short film is very hard task. Putting whole story in 5 to 10 minutes is not easy. Can you imagine? Few films produced after working hard more than 6 years! The Oh-My-God Particle by John Walker January 4, 1994 Fly's Eye The University of Utah operates a cosmic ray detector called the Fly's Eye II, situated at the Dugway Proving Ground about an hour's drive from Salt Lake City. The Fly's Eye consists of an array of telescopes which stare into the night sky and record the blue flashes which result when very high energy cosmic rays slam into the atmosphere. From the height and intensity of the flash, one can calculate the nature of the particle and its energy.

Kidrobot's Blog, The KRonikle UK designer, Aled Lewis crosses the streams of reality and 8-bit with a fun new photographic series. Aled is best known for his clever t-shirt illustrations on Threadless, but his latest project superimposes your favorite pixelated video game characters of yesteryear with photographs of real life scenarios. via fubiz Alcubierre Warp Drive Time Travel An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below). The key characteristics of the application of Alcubierre warp drives for time control and time travel are presented in the picture below. This is followed by more detail describing the effect below.

6 Life-Changing Uses for Binder Clips (That You Could've Easily Thought Of) from Look What I Found Yes, it may seem like an ordinary binder clip. And it is. Make no mistake -- it will keep your papers organized with the best of them. The BEST. But it's so much more. Physics envy In science, the term physics envy is used to criticize a tendency (perceived or real) of softer sciences and liberal arts to try to obtain mathematical expressions of their fundamental concepts, as an attempt to move them closer to harder sciences, particularly physics. Evolutionary biologist Ernst Mayr discusses the issue of the inability to reduce biology to its mathematical basis in his book What Makes Biology Unique?.[2] Noam Chomsky discusses the ability and desirability of reduction to its mathematical basis in his article "Mysteries of Nature: How Deeply Hidden."[3]
