The Large Scale Structure of Space-Time

Science & Nature

Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein's field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

Le temps des algorithmes

Science & Nature

Ils transforment les sciences, l’industrie, la société... Ils bouleversent les notions de travail, de propriété, de gouvernement, de vie privée... et d’humanité. Qui, aujourd’hui, n’a pas entendu parler des algorithmes ? Avec eux, nous passons facilement d’un extrême à l’autre : nous nous réjouissons qu’ils nous facilitent la vie, mais redoutons qu’ils nous asservissent…Pour en finir avec cette vision manichéenne, cet ouvrage propose un nouveau regard sur notre époque, sur le temps des algorithmes. Les algorithmes sont probablement les outils les plus sophistiqués que les hommes aient eu à leur disposition depuis les commencements de l’histoire de l’humanité. Créations de l’esprit humain, ils sont ce que nous avons voulu qu’ils soient. Et ils seront ce que nous voulons qu’ils soient : à nous de choisir le monde que nous voulons construire.

The Pressure Point

L'animal médecin

Science & Nature

Papillons, ours, moutons, chimpanzés ou dauphins connaissent les plantes, écorces et autres végétaux qui peuvent les soulager. Comment se transmettent-ils ce savoir ? Mieux : l’origine de notre médecine ne vient-elle pas de l’observation des sorciers et chamans qui regardaient les animaux guérir certains de leurs maux ? Ce livre explore un domaine encore peu connu qui porte l’étrange nom de zoopharmacognosie (l’automédication des animaux) mais aussi le pouvoir que les chats, les chevaux ou les chiens exercent sur les humains tant physiologiquement que psychologiquement. 12 spécialistes qui travaillent sur des domaines très variés, nous expliquent comment nos frères de poils et de plumes possèdent des savoirs qui nous échappent et comment ils peuvent nous les transmettre pour nous aider dans notre quotidien. Journaliste de presse écrite et radio, autrice de plusieurs livres, Yolaine de la Bigne a été sensibilisée à la nature grâce à ses collaborations avec Nicolas Hulot pour l’émission Ushuaïa. Elle se consacre aujourd'hui au sujet de l’intelligence animale à travers son association "L'Animal & l'homme" et ses deux évènements annuels, l'Université d'été au château de la Bourbansais en Bretagne, et la Journée mondiale des intelligences animales à la Cité des sciences et de l'industrie.

It seems that a significant capacity gain is achievable, particularly if they are employed on both sides of the connection. There are several essential characteristics of these systems that need scientific and technical investigation. Included in the book are beamforming, massive MIMO, network MIMO, mmwave transmission, compressive sensing, MIMO radar, sensor networks, vehicle-to-vehicle communication, location, and machine learning.

L'humérus et ses articulations chez les hominidés plio-pléistocènes

Science & Nature

L’étude comparative de la scapula, de l’humérus et des extrémités proximales de l’ulna et du radius — chez des primates actuels (platyrhiniens et catarhiniens) et chez les Hominidés plio-pléistocènes — a permis de distinguer les genres Australopithecus et Homo. Alors que les pièces rapportées à Homo ressemblent à l’homme moderne, celles attribuées à Australopithecus présentent des caractères à la fois humains et proches des formes suspendues de primates. On peut donc se demander s’il n’existait pas, chez ces dernières, une forme particulière de suspension.

Brainstorms

Science & Nature

«Credo che quest’opera di filosofia della mente sia di grandissima importanza» ha scritto Hilary Putnam a proposito di «Brainstorms». E Noam Chomsky: «Con tocco sicuro e una grande capacità di comprensione Dennett ha sottoposto ad analisi questioni che si pongono sulla frontiera dello studio scientifico della mente e del cervello – o forse già un po’ al di là di essa». Da parti ben distinte, dunque, questo libro è stato accolto come un passo decisivo in un’area dove oggi si svolge la ricerca più palpitante – la stessa che viene attraversata da Hofstadter nel suo «Gödel, Escher, Bach». Ma a tutto questo va aggiunto che, pur nel rigore della sua indagine, Dennett è riuscito a dare al suo libro una forma estremamente invitante, che «obbliga il lettore a pensare», come ha scritto Ned Block. «Brainstorms» è apparso per la prima volta nel 1978.

Svampenes forunderlige liv

Science & Nature

Svampenes hemmelige liv er en forunderlig bog om svampenes vidtrækkende rige skrevet af den britiske biolog Merlin Sheldrake. Der er noget fascinerende ved svampe. Hvad enten man tænker på dem, som vi kan finde i skoven eller i supermarkedet, eller dem der kan bruges til at fremstille penicillin og redde os fra alle mulige sygdomme, eller skimmelsvampe, der kan gøre os syge – eller gærsvampe, der bliver brugt til at lave øl, eller måske de magiske af slagsen, der kan ændre vores bevidsthedstilstand. Men hvad er de for nogle organismer? Merlin Sheldrake åbenbarer svampenes natur, sofistikerede eksistensform og muligheder for os. Det er overraskende og tankevækkende læsning. Nyere forskning tyder fx på, at svampe kan bruges til behandling af psykiske sygdomme som angst og depression, og der bliver arbejdet på at udvikle teknologi til at få svampe til at spise plastik, sprængstoffer og pesticider. Svampenes hemmelige liv henvender sig til et bredt publikum, den blander naturfortælling, videnskabsformidling, kulturhistorie og personlig beretning, og man er grundlæggende i godt selskab. Bogen efterlader læseren både klogere, mere nysgerrig og fuld af forundring og med et udvidet verdenssyn.

Protestare mentre tutto scorre

Science & Nature

Non è facile opporsi allo scorrere delle cose. È il progresso, dicono, non ha senso cercare di fermarlo. Non ha senso bloccare un treno che trasporta materiale radioattivo, utile soltanto a costruire bombe inutili. Non ha senso rimpiangere un mondo antico che verrà spazzato via per fare posto a enormi depositi per testate missilistiche in grado di distruggere l'intero pianeta. O forse protestare contro ingiustizie tanto grandi che sembrano ineluttabili è uno dei pochi modi per dare senso a un'esistenza? Forse, per trovare uno scampolo di felicità in vite di quieta disperazione, è necessario battersi per difendere un rivolo d'acqua che sgorga nel deserto. Edward Abbey, con gli occhi di un Thoreau disilluso, ci ricorda come la fragile meraviglia della natura venga sempre minacciata dal potere, e ci ricorda il costo e la gioia che si provano lottando per difenderla.

Reading in the Brain

Science & Nature

A renowned cognitive neuroscientist?s fascinating and highly informative account of how the brain acquires readingHow can a few black marks on a white page evoke an entire universe of sounds and meanings? In this riveting investigation, Stanislas Dehaene provides an accessible account of the brain circuitry of reading and explores what he calls the ?reading paradox?: Our cortex is the product of millions of years of evolution in a world without writing, so how did it adapt to recognize words? Reading in the Brain describes pioneering research on how we process language, revealing the hidden logic of spelling and the existence of powerful unconscious mechanisms for decoding words of any size, case, or font. Dehaene?s research will fascinate not only readers interested in science and culture, but also educators concerned with debates on how we learn to read, and who wrestle with pathologies such as dyslexia. Like Steven Pinker, Dehaene argues that the mind is not a blank slate: Writing systems across all cultures rely on the same brain circuits, and reading is only possible insofar as it fits within the limits of a primate brain. Setting cutting-edge science in the context of cultural debate, Reading in the Brain is an unparalleled guide to a uniquely human ability.
