Over 2,000 years after the discovery of the compass, Einstein known as the resource of Earth’s magnetic box considered one of maximum unsolved mysteries of physics. right here, for the 1st time, is the entire heritage of the search to appreciate Earth’s magnetism―from the traditional Greeks’ fascination with lodestone, to the geological discovery that the North Pole has now not regularly been within the North―and to the superb smooth conclusions that eventually published the genuine source.

Richly illustrated and assuredly informed, North Pole, South Pole unfolds the human tale at the back of the technological know-how: that of the inquisitive, persevering, and sometimes dissenting thinkers who unlocked the secrets and techniques at our planet’s core.

Download E-books Deus, um Delírio PDF

By Richard Dawkins

Num pace de guerras e ataques terroristas com motivações religiosas, o movimento pró-ateísmo ganha força no mundo todo. E seu líder é o respeitado biólogo Richard Dawkins, eleito recentemente um dos três intelectuais mais importantes do mundo (junto com Umberto Eco e Noam Chomsky) pela revista inglesa Prospect. Autor de vários clássicos nas áreas de ciência e filosofia, ele sempre atestou a irracionalidade de acreditar em Deus e os terríveis danos que a crença já causou à sociedade. Agora, neste "Deus, um Delírio", seu intelecto afiado se concentra exclusivamente no assunto e mostra como a religião alimenta a guerra, fomenta o fanatismo e doutrina as crianças. O objetivo relevant deste texto mordaz é provocar: provocar os religiosos convictos, mas principalmente provocar os que são religiosos "por inércia", levando-os a pensar racionalmente e trocar sua "crença" pelo "orgulho ateu" e pela ciência. Dawkins despreza a idéia de que a religião mereça respeito especial, mesmo se moderada, e compara a educação religiosa de crianças ao abuso infantil. Para ele, falar de "criança católica" ou "criança muçulmana" é como falar de "criança neoliberal" - não faz sentido. O biólogo united states seu conceito de memes (idéias que agem como os genes) e o darwinismo para propor explicações à tendência da humanidade de acreditar num ser better. E desmonta um a um, com base na teoria das probabilidades, os argumentos que defendem a existência de Deus (ou Alá, ou qualquer tipo de ente sobrenatural), dedicando especial atenção ao "design inteligente", tentativa criacionista de harmonizar ciência e religião.

Download E-books The Evolution of Everything: How New Ideas Emerge PDF

The manhattan occasions bestselling writer of The Rational Optimist and Genome returns with a desirable argument for evolution that definitively dispels a deadly, common fable: that we will command and keep an eye on our world.

Human society evolves. swap in expertise, language, morality, and society is incremental, inexorable, sluggish, and spontaneous. It follows a story, going from one degree to the subsequent; it creeps instead of jumps; it has its personal spontaneous momentum instead of being pushed from open air; it has no objective or result in brain; and it mostly occurs via trial and error—a model of ordinary choice. a lot of the human international is the results of human motion yet no longer of human layout: it emerges from the interactions of hundreds of thousands, now not from the plans of a few.

Drawing on attention-grabbing facts from technological know-how, economics, background, politics, and philosophy, Matt Ridley demolishes traditional assumptions that the good occasions and developments of our day are dictated by way of these on excessive, even if in govt, company, academia, or equipped faith. to the contrary, our most vital achievements advance from the ground up. simply as skeins of ducks shape Vs within the sky with no desiring to and ter-mites construct dust cathedrals with out architects, so brains take form with out brain-makers, studying occurs with no educating, and morality alterations for no cause except the present style. even if we forget, defy, and forget about them, bottom-up traits form the realm. the economic Revolution, mobile phones, the increase of Asia, and the web have been by no means deliberate; they occurred. Languages emerged and advanced by means of a kind of usual choice, as did universal legislations. Torture, racism, slavery, and pedophilia—all as soon as largely appeared as acceptable—are now obvious as immoral regardless of the decline of faith in fresh many years. during this wide-ranging and erudite e-book, Ridley brilliantly makes the case for evolution, instead of layout, because the strength that has formed a lot of our tradition, our know-how, our minds, and that even now's shaping our future.

As compelling because it is arguable, as authoritative because it is bold, Ridley’s deeply thought-provoking booklet will swap the way we take into consideration the realm and the way it works.

Download E-books Political Animals: How Our Stone-Age Brain Gets in the Way of Smart Politics PDF

By Rick Shenkman

Can a soccer online game impact the result of an election? What approximately shark assaults? Or a drought? In a rational global the reply, after all, will be no. yet as bestselling historian Rick Shenkman explains in Political Animals, our global is something yet rational. Drawing on technology, politics, and heritage, Shenkman explores the hidden forces at the back of our usually illogical choices.

Political Animals demanding situations us to move past the headlines, which frequently specialise in what politicians do (or say they’ll do), and to pay attention as a substitute on what’s relatively vital: what shapes our reaction. Shenkman argues that, opposite to what we inform ourselves, it’s our instincts instead of arguments attractive to cause that typically be successful. popular culture tells us we will belief our instincts, yet technology is proving that once it involves politics our Stone Age mind frequently malfunctions, misfires, and leads us astray.

Fortunately, we will be able to learn how to make our instincts paintings in our prefer. Shenkman takes readers on a whirlwind journey of laboratories the place scientists are exploring how sea slugs keep in mind, chimpanzees perform deception, and sufferers whose brains were cut up in inform tales. The scientists’ findings provide us new methods of realizing our historical past and ourselves—and turn out we don’t need to be prisoners of our evolutionary past.”

In this attractive, illuminating, and sometimes riotous chronicle of our political tradition, Shenkman probes the depths of the human brain to discover how we will develop into extra political, and not more animal.
