Il più grande spettacolo della Terra

Science & Nature

Nel 1859 L'origine delle specie di Charles Darwin scosse il mondo dalle fondamenta. Darwin sapeva benissimo che la sua teoria dell'evoluzione avrebbe provocato un terremoto, ma non avrebbe mai potuto immaginare che, un secolo e mezzo dopo, la controversia avrebbe continuato a infuriare. L'evoluzione è considerata un «fatto» da tutti gli scienziati autorevoli, e per la verità anche dai teologi più illuminati, eppure milioni di persone continuano a negarla o per ignoranza o per obbedienza a una religione, con risultati inquietanti. Richard Dawkins si inserisce nel dibattito in corso e fornisce un'esauriente panoramica delle prove scientifiche dell'evoluzionismo, prendendo in esame le varie discipline, dalla chimica alla biologia, dall'embriologia alla paleontologia, e le moderne strumentazioni che contribuiscono a confermare sotto molteplici profili la realtà dell'evoluzione e, dopo aver sfatato la leggenda degli anelli mancanti (in realtà ne mancano sempre meno...), conduce il lettore lungo l'affascinante itinerario di studi aperto da Darwin. E lo fa scavando in una miniera di evidenze scientifiche: analizza gli esempi viventi di selezione naturale e i reperti fossili, gli orologi naturali che hanno segnato le tappe del lungo processo evolutivo e le complesse fasi di sviluppo dell'embrione, le dinamiche della tettonica a placche e i meccanismi della genetica molecolare. Per giungere a una conclusione incontrovertibile: «Non è un caso che ci ritroviamo appollaiati su un ramoscello sottile in mezzo al rigoglioso, fiorente albero della vita. Non è un caso, bensì la diretta conseguenza dell'evoluzione per selezione naturale non casuale». Mentre in tutto il mondo è in atto il tentativo di minare alla radice l'autorevolezza della scienza, con Il più grande spettacolo della Terra Dawkins sceglie di partecipare alla battaglia contro ogni vecchia e nuova forma di oscurantismo riproponendo la lucida visione delle leggi della vita che porta il nome di uno dei più grandi scienziati di ogni tempo.

Anaximander

Science & Nature

THIS BOOK WILL NO LONGER BE AVAILABLE AFTER SEPTEMBER 10, 2021.Carlo Rovelli, a leading theoretical physicist, uses the figure of Anaximander as the starting point for an examination of scientific thinking itself: its limits, its strengths, its benefits to humankind, and its controversial relationship with religion. Anaximander, the sixth-century BC Greek philosopher, is often called the first scientist because he was the first to suggest that order in the world was due to natural forces, not supernatural ones. He is the first person known to understand that the Earth floats in space; to believe that the sun, the moon, and the stars rotate around it—seven centuries before Ptolemy; to argue that all animals came from the sea and evolved; and to posit that universal laws control all change in the world. Anaximander taught Pythagoras, who would build on Anaximander’s scientific theories by applying mathematical laws to natural phenomena.In the award-winning The First Scientist: Anaximander and His Legacy, translated here for the first time in English, Rovelli restores Anaximander to his place in the history of science by carefully reconstructing his theories from what is known to us and examining them in their historical and philosophical contexts. Rovelli demonstrates that Anaximander’s discoveries and theories were decisive influences, putting Western culture on its path toward a scientific revolution. Developing this connection, Rovelli redefines science as a continuous redrawing of our conceptual image of the world. He concludes that scientific thinking—the legacy of Anaximander—is only reliable when it constantly tests the limits of our current knowledge.

Der Wissenschaftswahn

Science & Nature

Rupert Sheldrake hat mit dem "Wissenschaftswahn" ein Standardwerk geschaffen – eine schlagkräftige Antwort auf den "Gotteswahn" von Richard Dawkins. Der berühmte Biologe zeigt anhand von zehn "Dogmen", dass die meisten Forscher an Vorstellungen festhalten, die vollkommen überholt und eindeutig widerlegbar sind. Er fordert ein neues und grenzüberschreitendes Denken und plädiert für mehr Offenheit und Neugier in den Naturwissenschaften. Aktualisierte Taschenbuchneuausgabe eines der Hauptwerke des großen Visionärs. Die 10 Dogmen der Naturwissenschaften:1. Alles ist mechanischer Natur.2. Materie besitzt grundsätzlich kein Bewusstsein.3. Die Gesamtheit von Materie und Energie ist immer gleich.4. Die Naturgesetze stehen ein für alle Mal fest.5. Die Natur kennt keine Absichten.6. Biologische Vererbung ist ausschließlich materieller Natur.7. Der Geist, unser Denken und Fühlen, sitzt im Kopf.8. Erinnerungen sind materielle Spuren im Gehirn.9. Unerklärliche Phänomene wie Telepathie sind reine Einbildung.10. Mechanische Medizin ist die einzig wirksame Medizin.Das materislistische Welt ist obsolet geworden. Nüchtern, sachlich und ohne jede Esoterik zeigt hier ein Naturwissenschaftler, wie fadenscheinig und oberflächlich die Argumente der Vertreter eines reinen Materialsmus geworden sind. sheldrake fodert einen Neuanfang in Philosophie und Wissenschaft, der überfällig ist und Wissenschaft und Spiritualität auf die Dauer zusammenführen wird.

Le roman de la radio

Science & Nature

« (...) Dans ce livre, c’est toute la radio — avant, pendant, après la guerre — qu’il raconte. Cette radio qui lui a toujours été nécessaire, autant que l’air qu’il respire. Roland Dhordain n’a pas seulement fait de la radio toute sa vie, il est la radio. Je l’ai toujours connu débordant d’enthousiasme, épanoui dès qu’il entrait dans un studio, dans une régie, dès qu’il se penchait vers un micro ou invitait quelqu’un à y parler. « Dans cette histoire, qu’il conte avec tant d’allégresse — à chaque instant, le témoin et l’expert viennent donner à l’historien un inestimable coup de main — c’est comme une épopée qu’il ressuscite (...) » Alain Decaux, de l’Académie française.

El orden del tiempo

Science & Nature

Los misterios del tiempo explicados por un eminente físico que, además, es un gran divulgador. Un ensayo apasionante.¿Qué es el tiempo? ¿Hasta qué punto lo entendemos? ¿Existimos en el tiempo o el tiempo existe en nosotros? ¿Por qué recordamos el pasado y no el futuro? ¿Qué quiere decir que el tiempo «corre»? ¿El pasado está cerrado y el futuro abierto? ¿El tiempo es lineal? ¿Existe de verdad?... Carlo Rovelli, físico cuyo anterior libro –Siete breves lecciones de física, publicado en esta colección– se tradujo a cuarenta idiomas y se convirtió en un sorprendente bestseller internacional, responde a estas y otras preguntas.El tiempo es un misterio no solo para los profanos, sino también para los físicos, que a lo largo de la historia han ido modificando su percepción de él: de Newton a Einstein y a la gravedad cuántica de bucles, en la que el autor es experto. Rovelli aborda el tiempo y sus enigmas con una combinación única de rigor, capacidad divulgativa y bagaje humanístico que le permite incorporar al texto la mitología hindú, el Mahābhārata y a Guillermo de Ockham, Proust, Rilke...El libro se divide en tres partes: la primera aborda lo que a día de hoy sabe la física moderna sobre el tiempo y los cambios radicales que se han producido en torno a algunos temas que se daban por cerrados; la segunda se centra en la gravedad cuántica y aborda la idea de un mundo sin tiempo, mientras que la tercera explora el nacimiento del tiempo y el modo en que lo experimentamos.El resultado es un ensayo esclarecedor y apasionante, que nos da claves –científicas, pero también filosóficas– para entender el misterio del tiempo, un tema central de la física y de nuestra relación con la vida y el universo.
