J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

In the years following her role as the lead author of the international best seller, Limits to Growth - the first book to show the consequences of unchecked growth on a finite planet - Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem-solving on scales ranging from the personal to the global. Edited by the Sustainability Institute's Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world....

Cette "Brève histoire de l'humanité" déroule notre histoire globale, des premiers hominidés à aujourd'hui et interroge l'avenir qui nous attend. Comment l'"Homo Sapiens" a-t-il réussi à dominer la Terre ? Quelle singularité nous a permis de s'unir pour créer villes et empires, l'idée de religion, les concepts politiques de nation ou plus récemment des droits de l'homme ? Pourquoi cette dépendance et cette croyance que notre bonheur dépend de l'argent et de la possibilité de consommer ?

In this uniquely all-encompassing book about fungi, mycologist Keith Seifert looks at a variety of different types of fungi, including those that are invisible to the naked eye, and those that live in relationship to humans, agriculture, animals, forests, cities, and more.

No one has done more to transform our understanding of trees than the world-renowned scientist Suzanne Simard. Raised in the forests of British Columbia, where her family has lived for generations, Professor Simard did not set out to be a scientist. She was working in the forest service when she first discovered how trees communicate underground through an immense web of fungi, at the centre of which lie the Mother Trees: the mysterious, powerful entities that nurture their kin and sustain the forest.

Have you ever wondered why you have a brain? Let renowned neuroscientist Lisa Feldman Barrett demystify that big gray blob between your ears. In seven short essays (plus a bite-sized story about how brains evolved), this slim, entertaining, and accessible collection reveals mind-expanding lessons from the front lines of neuroscience research. You'll learn where brains came from, how they're structured (and why it matters), and how yours works in tandem with other brains to create everything you experience.

The periodic table of elements, first encountered by many of us at school, provides an arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, and divided into periodic trends. In this Very Short Introduction audiobook, Eric R. Scerri looks at the trends in properties of elements that led to the construction of the table and shows how the deeper meaning of the table's structure gradually became apparent with the development of atomic theory.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

No running water, no car, no electricity or any of the things it powers: the internet, phone, washing machine, radio, or light bulb. Just a wooden cabin, on a smallholding, by the edge of a stand of spruce. The Way Home is a modern-day Walden - an honest and lyrical account of a remarkable life lived in nature without modern technology. Mark Boyle, author of The Moneyless Man, explores the hard-won joys of building a home with his bare hands, learning to make fire, collecting water from the stream, foraging, and fishing.

By calling everything into doubt, Descartes laid the foundations of modern philosophy. With the celebrated words "I think therefore I am," his compelling argument swept aside ancient and medieval traditions. He deduced that human beings consist of minds and bodies; that these are totally distinct "substances"; that God exists and that He ensures we can trust the evidence of our senses.

Few fish are as beloved, or as obsessed over, as the American shad. Although shad spend most of their lives in salt water, they enter rivers by the hundreds of thousands in the spring and swim upstream heroic distances in order to spawn, then return to the ocean.

Long before Oliver Sacks became a distinguished neurologist and best-selling writer, he was a small English boy fascinated by metals - also by chemical reactions (the louder and smellier the better), photography, squids and cuttlefish, H.G. Wells, and the periodic table. In this endlessly charming and eloquent memoir, the he chronicles his love affair with science and the magnificently odd and sometimes harrowing childhood in which that love affair unfolded.

今回のテーマを取り上げようと思ったきっかけは、先日、米コンシューマリポートが報告した調査記事だった。同社は毎年、自動車メーカーのブランド力をいくつかの切り口からスコアリングして順位を付けている。ドイツのメーカーに比べ、日本メーカーは信頼感で勝るスコアを付けることが多く、とりわけレクサスやトヨタが強いランキングだ。今年もナンバーワンはレクサスだったが、2位には意外なメーカーが顔を覗かせていた。マツダである。3位以下はトヨタ、アウディ、スバル、ポルシェ、ビュイックと続く。マツダは昨年、トップ5にも入っていなかったというのに大躍進したのだ。こうした様々な自動車関連のランキングや評価が掲載されたコンシューマリポートの2015年の自動車特集号の表紙は、数ある新発表車種の中からMAZDA MX-5（日本名：ロードスター）が選ばれている。(本文より)本田雅一　続・モバイル通信リターンズはこちらから→http://yakan-hiko.com/honda.html

Discover magazine recently called Richard Dawkins "Darwin's Rottweiler" for his fierce and effective defense of evolution. Prospect magazine voted him among the top three public intellectuals in the world (along with Umberto Eco and Noam Chomsky). Now Dawkins turns his considerable intellect on religion, denouncing its faulty logic and the suffering it causes.

In a field known for startling ideas, the Many-Worlds Interpretation (MWI) of quantum mechanics may take the prize. It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved.
