For forsta gngen forklaras vad som ligger bakom och "driver" alla de fyra naturkrafterna; gravitationen, magnetismen och de tv typerna av karnkrafter i en atomkarna. Den enhetliga och sammanhllande teorin, eftersokt av forskare p omrdet, banar ocks vagen till en logisk forklaring p de krafter som driver elektriciteten, samt de krafter vi kallar kemiska bindningar. I det senare fallet ges det en forklaring p varfor atomer forsoker f tillgng till 8 elektroner i sitt yttersta skal, vilket styr utformandet av alla molekyler.Eftersom allt "hanger" ihop, fr vi samtidigt ocks en forklaring till fenomen som bl.a. tunneleffekten, Cooper-par, supraledare och supravatska. I tillagg visar boken att fotonen inte finns, och att den ej heller behover finnas for att forklara forandringar i atomers vikt vid fusioner/fissioner.Och den kosmiska bakgrundsstrlningen ar, trots alla fina detaljer frn forskning, inget annat an vgor och brus frn strangarnas hav. Det ar detta hav, tillsammans med oar i form av stjarnor och planeter, som utgor vrt universum.Se och forst verklighetens hela bild. Boken presenterar den klart och tydligt, en bild dar alla pusselbitar passar, en bild som tidigare bara har visat delar av sin utsida, tolkad av matematiska formler, figurer och diagram, baserade p bl.a. Lorentz faktor. En faktor, som enligt boken, aldrig borde ha formulerats.Fotonen finns inte,Big Bang hande aldrigoch kejsaren har heller inga klader.

Der NameMichael Faradaygehort einem der seltenen Geister an, welche der Menschheit neue Bahnen auf dem Gebiete der Naturwissenschaft eroffnet haben. AberMichael Faradaywar nicht nur ein groer Naturforscher: er war zugleich auch ein guter und edler Mensch, der seine Mitmenschen, und nicht am wenigsten die Jugend liebte. Gern stieg er selbst zu den Kindern herab, um ihnen in seiner schlichten und herzerfreuenden Weise aus dem reichen Schatze seines Wissens goldene Fruchte zu bieten. Darum wird es gut sein, wenn wir den Mann, von dem man so treffliche Dinge lernen kann, auch selbst ein wenig kennen lernen. Es soll daher in den folgenden Zeilen einiges aus seinem Leben erzahlt werden.

Os textos que compem esta obra apresentam reflexes de estudantes de um Curso de Mestrado Profissional em Ensino de Ciencias e de um Curso de Licenciatura em Ciencias Exatas, em parceria com seus professores e orientadores, sobre o ensino de Ciencias e Geociencias, fundamentadas na teoria da complexidade de Edgar Morin. O metodo de ensino e aprendizagem proposto pela teoria da complexidade se faz aberto a possibilidades, ao vir a ser a incertezas, ao erro e, tambem, a inovaço proprios do estudo de transformaçes sociais, de culturas escolares e de outros tantos fenomenos complexos de natureza existencial. No processo de aprender, educador e aprendiz so mutuamente influenciados pelas possibilidades abertas por estrategias pedagogicas que modificam o percurso do programa curricular previamente estabelecido. Tanto o refinamento de estrategias quanto novos conhecimentos surgem durante a experiencia, enquanto no seu inicio apresentavam-se apenas como possibilidades. Discutindo a ciencia da complexidade, que busca compreender o devir natural, esta obra traz reflexes sobre as instabilidades, o inusitado e as indeterminaçes proprias da vida. Em suas escritas, os autores defendem a importancia de superar os modelos baseados em programas lineares e organizados para transmitir informaçes sequencialmente.

A symbolization of Heaven on Earth as a supreme religious tribute by the Nuraghic people or just a mere coincidence? The visual similarity of the position of the nuraghes as compared to the Open star cluster Messier 45 (known as the Pleiades) is absolutely striking.The daily life of ancient societies was very much influenced by the movements of the sun, moon, planets and specific stars and constellations such as the Great Bear, Orion and the Pleiades. This was even more true before calendars and time markers came into use. The significance was such that the observation and prediction of the celestial events became of profound religious importance and also represented a way to condition the political power over human communities all over the world. The Bronze Age Nuraghic Civilisation in Sardinia was no exception.This book explains in detail the prominent role that the Pleiades had in many civilizations and also an enterprising hypothesis made by the archaeologist Augusto Mulas that the unusual arrangement of a group of nuraghes around the Santu Antine of Torralba was purposely set up by its ancient constructors to represent the Sacred star cluster. To support this hypothesis, in the second part of the book, engineer Marco Sanna illustrates a probability calculus which demonstrates that the positioning of the group of nuraghes was almost certainly deliberate, with nearly 96% of likelihood.

Proiettandosi nel futuro si analizzano le tendenze a lungo termine, demografiche, economiche, sociali e ambientali, nonché i modelli politici e culturali delle varie regioni del mondo e le risorse naturali. Si ritiene che il futuro venga plasmato sulla base delle nuove tecnologie e della situazione dei mercati. Purtroppo, la crescita economica irregolare e isole di prosperita accanto a oceani di poverta e disperazione lascerebbero prevedere un possibile crescente degrado ambientale e caos sociale. Rimane la speranza che i cambiamenti sociali e politici e lemergere di nuove tecnologie migliorino la qualita di vita dei popoli e che nascano nuove forme di partecipazione politica con uneconomia verde e sostenibile. Il futuro sara plasmato dalle scelte che facciamo oggi ed e importante che tutti ci impegniamo per un futuro sostenibile e inclusivo, basato sui valori della giustizia, dellequita e della solidarieta. Solo cosi si possono affrontare le sfide del futuro e costruire un mondo migliore.

Herbert George Wells (1866-1946) was one of the most popular British writers of all time. Prolific in many genres, he wrote more than fifty novels and dozens of short stories. His non-fiction output included works of social commentary, politics, history, popular science, satire, biography and autobiography. Wells is now best remembered for his Science Fiction novels and has been called the Father of Science Fiction. In addition to his fame as a writer, he was prominent in his lifetime as a forward-looking, even prophetic social critic who devoted his literary talents to the development of a progressive vision on a global scale. A futurist, he wrote a number of utopian works and foresaw the advent of aircraft, tanks, space travel, nuclear weapons and satellite television. His Science Fiction imagined time travel, alien invasion, invisibility, and biological engineering before these subjects were common in the genre.Zoological Retrogression, first published in September 1891 in The Gentlemans Magazine, is one of Wells most interesting scientific studies.In the second half of the 19th century was widespread the theory that civilization could be in decline and that the causes of the decline lay in biological change. Wells concludes his study with this caveat: The Coming Beast must certainly be reckoned in any anticipatory calculations regarding the Coming Man.

Have you read Baruch? La Fontaine used to cry, enthusiastically. To-day he would have troubled his friends with the question Have you read Einstein?But, whereas one needs only a little Latin to gain access to Spinoza, frightful monsters keep guard before Einstein, and their horrible grimaces seem to forbid us to approach him. They stand behind strange moving bars, sometimes rectangular and sometimes curvilinear, which are known as co-ordinates. They bear names as frightful as themselvescontravariant and covariant vectors, tensors, scalars, determinants, orthogonal vectors, generalised symbols of three signs, and so on.These strange beings, brought from the wildest depths of the mathematical jungle, join together or part from each other with a remarkable promiscuity, by means of some astonishing surgery which is called integration and differentiation.In a word, Einstein may be a treasure, but there is a fearsome troop of mathematical reptiles keeping inquisitive folk away from it; though there can be no doubt that they have, like our Gothic gargoyles, a hidden beauty of their own. Let us, however, drive them off with the whip of simple terminology, and approach the splendour of Einsteins theory.

Part I of this book series puts vertebrates (Chordata) of the North Sea, from sea-squirts to lampreys, sharks and rays, bony fishes, seals and whales, in the context of the changing living conditions in this small part of the one big ocean. The book presents a balance between long-established species and immigrants from the subtropics. Aspects of fishing, ecology and aquarium keeping were also included in this work. In addition, the preparation of fish was also addressed. It would be very welcome, if in the future more people would concern themselves with the care and preservation of the wondrous and multifarious inhabitants of the North Sea. For unfortunately, many of the species shown here seem to be largely unknown to a wider public, which is why they hardly seem to have a real lobby in practice. So, we`d better get to know our endemic species, before they become extinct.

In questo suo breve saggio, Daniele Biancardi riassume sinteticamente le cause del celebre libro di Charles Darwin Lorigine della specie (1859), nel quale il famoso biologo spiega la sua teoria dellevoluzione, riportando le osservazioni che egli stesso aveva compiuto durante una spedizione, secondo cui gruppi di organismi di una stessa specie si evolvono gradualmente nel tempo, attraverso il processo di selezione naturale.
