    It took a year to accumulate enough so that one could actually see it. Now there is so much that we don't know what to do to get rid of it. We have created a monster.The history of plutonium is as strange as the element itself. When scientists began looking for it, they did so simply in the spirit of inquiry, not certain whether there were still spots to fill on the periodic table. But the discovery of fission made it clear that this still-hypothetical element would be more than just a scientific curiosity?it could be a powerful nuclear weapon.As it turned out, it is good for almost nothing else. Plutonium's nuclear potential put it at the heart of the World War II arms race?the Russians found out about it through espionage, the Germans through independent research, and everybody wanted some. Now, nearly everyone has some?the United States alone has about 47 metric tons?but it has almost no uses besides warmongering. How did the product of scientific curiosity become such a dangerous burden?In his new history of this complex and dangerous element, noted physicist Jeremy Bernstein describes the steps that were taken to transform plutonium from a laboratory novelty into the nuclear weapon that destroyed Nagasaki. This is the first book to weave together the many strands of plutonium's story, explaining not only the science but the people involved.

    In April 1868, a very young John Muir stepped off a boat in San Francisco and inquired about the quickest way out of town. “But where do you want to go?” was the response, to which Muir replied, “Anywhere that is wild.” Using Muir’s personal correspondence and published articles, Peter and Donna Thomas have reconstructed the real story of Muir’s literal ramblings over California hills and through dales, with lofty Sierra Nevada peaks, Englishmen, and bears mixed in for good measure. The trip is illustrated by charming cut-paper illustrations that take their inspiration from Muir's love of nature. John Muir’s story-telling is so compelling that even 150 years later, seeing the world through his eyes makes us want to head out into the wild.

    Originally published in The Atlantic magazine in 2008, "Is Google Making Us Stupid?" set off a worldwide debate about the cognitive and cultural consequences of our infatuation with computers and online media.The New York Times called it the article that "everyone is talking about."

This edition of the essay includes an author's note on his sources. Approximately 5000 words in length.Cover hummingbird photo by Dan Pancamo (www.flickr.com/photos/pancamo/) used under Creative Commons license (creativecommons.org/licenses/by-sa/2.0/).

    Surprisingly, a great many players surveyed did not even know you need to hit down to get the ball up in the air. Hit Down @#!*% ! concisely explains the concept - and the technique - of hitting down at the golf ball for proper trajectory, increased backspin, much improved distance, proper divot taking, and best of all: consistent shotmaking.If you are inadvertently - or intentionally - hitting up at the ball, Hit Down @#!*% ! is for you. (Also available as DVD series, and MP3 download, all on Amazon.)If you are a seasoned amateur who has inexplicably “plateaud” - just cannot seem to get to the next level despite lessons and/or acquiring a library of books and videos - Hit Down @#!*% ! is for you.Symptoms of hitting up include (but are not limited to): - topping the ball- skulling the ball- pushing the ball- slicing the ball- poor distance- difficulty getting off back foot- poor backspin- no divot- fat divots- chunking the ball- thin/fat chip shots- roofing the ball with your driver- inability to hit long irons and/or fairway woods- good shots followed immediately by poor shotsHitting down at the golf ball is not a new concept, but it is a hitherto poorly explained (or completely avoided) concept. All pros agree on the need to hit down, so there is no debate there. Even Tiger Woods, in his 306 page “How I Play Golf”, states the need to hit down at the ball – but does not explain how. Hit Down @#!*% ! does. Learn to hit down, watch the ball go up, and your scores go down.

    She describes what habits we need to change to make STEM fun again, as well as a plan for how to increase every child's participation in these disciplines. The 21st century requires a new kind of learner -- not someone who can simply churn out answers by rote, as has been done in the past, but a student who can think expansively and solve problems resourcefully. In order to solve the complex problems of tomorrow, the traditional academic skills of reading, 'riting, and 'rithmetic must be replaced with creativity, curiosity, critical thinking, problem solving, and collaboration skills -- skills inherent in scientific research.
