 子どもたちの「理科離れ」が指摘されています。学力や知識の低下だけでありません。身近のことに関心を示したり興味を持ったりしなくなりました。さらには、疑問を解くための理論的な考察を避ける傾向が強くなりました。その結果、観察や実験は面倒くさいもの、理科は理屈っぽくて難しいものとして嫌うようになったようです。<br /> その原因は何でしょうか。私は二つ考えています。<br /> 一つは、情報があまりに多く与えられすぎて、身の回りの出来事から体験的に何かを知る喜び、発見する喜びが失われてしまったことです。私が子どもの頃は、知識を持つことは尊敬の対象でした。昆虫に詳しい同級生は「昆虫博士」とあだ名がついていました。今では知識は努力して調べるものではなく手軽に検索するものです。へんに物事に詳しいと「おたく」とか「マニア」とか呼ばれて逆にバカにされてしまいます。知識を蓄積することよりも知識を取捨選択することが大切な時代です。これでは、知る喜びや発見する喜びを得ることはできません。<br /> 二つめは、周りの大人たちが早い時期から物事を教えすぎて、自分の頭で考える機会を奪っていることです。例えば、子どもたちは何歳のときに「地球は丸い」ことを知るのでしょうか。小学校に入学する頃にはたいていの子どもたちは、地球が丸くて太陽の周りを回っていることを知っています。「どうしてそう考えるの」と訊いても「そんなの常識だよ」と答えるばかりです。どう見ても太陽が動いているように見える現実を疑問に思うことはありません。太陽が地球の周りを回っているように見えても実はそうではない。そのことを不思議に思って興味を持たなければ理科を好きにはなれません。なぜならば、理科とはなぜ物事がそうなるのかを根本的に考える学問だからです。<br /> そうした子どもたちのために「1000字で読む科学の話」シリーズを出版します。身近なテーマを一つずつ取り上げて科学的に紹介します。詳細に語り尽くさず概要だけに留め、まずは理科に興味をもってもらうことを主眼に置きました。また、中学受験にも対応できるように時事的な要素も取り込みました。今何が問題になっているのか、未来に向けてどのように考えればよいのか。真剣に考えてくれる子どもたちが一人でも増えてくれるならば、筆者としてこれに過ぎる喜びはありません。子どもたちと一緒に大人の方々にもぜひ読んでいただきたいと思います。<br /> 1000字とはどの程度の文章かと思われるかもしれません。参考までにこの紹介文が約1000字です。<br />

We all know about magnetism right? Where does this force come from in the first place? Did magnetism play a role in the creation of the universe? Why is this force important in everything from atomic structure to the way solar flares form? This easy-to-read, jargon-free essay addresses some of these issues and more and contains many useful references on electromagnetism and thus an aid to physics students.

Science and science fiction have become inseparable--with common stories, interconnected thought experiments, and shared language. This reference book lays out that relationship and its all-but-magical terms and ideas. Those who think seriously about the future are changing the world, reshaping how we speak and how we think.<br /> This book fully covers the terms that collected, clarified and crystallized the futurists' ideas, sometimes showing them off, sometimes slowing them down, and sometimes propelling them to fame and making them the common currency of our culture.<br /> The many entries in this encyclopedic work offer a guided tour of the vast territories occupied by science fiction and futurism. In his Foreword, David Brin says, "Provocative and enticing? Filled with 'huh!' moments and leads to great stories? That describes this volume."

Les observations d'ovnis se multiplient dans le monde. Et notre vision du cosmos explose. Tandis que l'on découvre des exoplanètes chaque semaine, la NASA publie une étude incroyable : il y a au moins 60 milliards de planètes pouvant abriter la vie. Dans notre seule galaxie ! Et le nombre de galaxies vient de passer de 100 milliards à... 2 000 milliards ! Non seulement nous ne sommes pas seuls dans l'univers, mais la vie intelligente foisonne, sur des milliards d'autres planètes ! Avec cette question angoissante : que représentons-nous sur l'échelle des intelligences extraterrestres ? Jean-Pierre Petit, ancien directeur de recherche au CNRS, révèle le résultat de quarante ans de recherches. Oui, le voyage d'une étoile à l'autre est possible... mais en prenant des raccourcis de l'espace-temps. Ainsi, des civilisations extraterrestres utiliseraient les lois physiques d'un autre univers pour rejoindre le nôtre et nous observer depuis des millénaires. Dans ces couloirs du temps, les voyages cosmiques ont des propriétés extraordinaires décrites par Jean-Pierre Petit. Ses calculs et hypothèses ont été publiés dans des revues scientifiques de haut niveau à comité de lecture. Pour la première fois au monde, il vous est proposé de participer à un réseau mondial de détection automatique d'ovnis, grâce à un petit appareil, de faible cout, à installer sur toits et balcons, que les passionnés pourront monter eux-mêmes et dont les schémas figurent en fin d'ouvrage.Enfin, Jean-Pierre Petit révèle l'inquiétant sectarisme de la recherche en France, où les blocages sont immédiats dès que l'on aborde le dossier ovni, tandis que les militaires sont en embuscade pour récupérer les données scientifiques.

<p><strong>Today's most visionary thinkers reveal the cutting-edge scientific ideas and breakthroughs you <em>must</em> understand.</strong></p><p>Scientific developments radically change and enlighten our understanding of the world -- whether it's advances in technology and medical research or the latest revelations of neuroscience, psychology, physics, economics, anthropology, climatology, or genetics. And yet amid the flood of information today, it's often difficult to recognize the truly revolutionary ideas that will have lasting impact. In the spirit of identifying the most significant new theories and discoveries, John Brockman, publisher of Edge.org ("The world's smartest website" -- <em>The Guardian</em>), asked 198 of the finest minds <em>What do you consider the most interesting recent scientific news? What makes it important?</em></p><p>Pulitzer Prize-winning author of <em>Guns, Germs, and Steel </em><strong>Jared Diamond<em> </em></strong>on the best way to understand complex problems * author of <em>Seven Brief Lessons on Physics</em> <strong>Carlo Rovelli </strong>on the mystery of black holes * Harvard psychologist <strong>Steven Pinker</strong> on the quantification of human progress * TED Talks curator <strong>Chris J. Anderson </strong>on the growth of the global brain * Harvard cosmologist <strong>Lisa Randall</strong> on the true measure of breakthrough discoveries * Nobel Prize-winning physicist <strong>Frank Wilczek </strong>on why the twenty-first century will be shaped by our mastery of the laws of matter * philosopher <strong>Rebecca Newberger Goldstein</strong> on the underestimation of female genius * music legend <strong>Peter Gabriel</strong> on tearing down the barriers between imagination and reality * Princeton physicist <strong>Freeman Dyson</strong> on the surprising ability of small (and cheap) upstarts to compete with billion-dollar projects.

<DIV><STRONG>A beautifully written, deeply provocative inquiry into the intersection of animal and disability liberation—and the debut of an important new social critic</STRONG><BR><BR>How much of what we understand of ourselves as "human" depends on our physical and mental abilities—how we move (or cannot move) in and interact with the world? And how much does our definition of "human" depend on its difference from "animal"?<BR><BR>Drawing on her own experiences as a disabled person, a disability activist, and an animal advocate, author Sunaura Taylor persuades us to think deeply, and sometimes uncomfortably, about what divides the human from the animal, the disabled from the nondisabled—and what it might mean to break down those divisions, to claim the animal and the vulnerable in ourselves, in a process she calls "cripping animal ethics." <BR><BR><EM>Beasts of Burden</EM> suggests that issues of disability and animal justice, which have heretofore primarily been presented in opposition, are in fact deeply entangled. Fusing philosophy, memoir, and science—including factory farming, disability oppression, and our assumptions of human superiority over animals—Taylor draws attention to new worlds of experience and empathy that will open up important avenues of solidarity across species and ability. <EM>Beasts of Burden</EM> is a wonderfully engaging and elegantly written work, both philosophical and personal, by a brilliant debut author.<BR></DIV>
