Conditions of Existence as Affecting the Perpetuation of Living Beings

Science & Nature

A philosophical study presented by the biologist author has been depicted in this book. There is no doubt that breeds may be made as different as species in many physiological characters. So with Dogs in their habits and instincts. It is a physiological peculiarity which leads the Greyhound to chase its prey by sight, —that enables the Beagle to track it by the scent, that impels the Terrier to its rat-hunting propensity, and that leads the Retriever to its habit of retrieving. These habits and instincts are all the results of physiological differences and peculiarities, which have been developed from a common stock, at least there is every reason to believe so.

Voyage aux frontières de la vie

Science & Nature

Nathalie A. Cabrol a cinq ans lorsqu'elle regarde le premier homme poser le pied sur la Lune. Pointant du doigt l’écran de télévision, elle dit à sa mère que c’est ce qu’elle veut faire. Quand on la questionne sur sa vocation, elle répond qu’elle n’a jamais rien voulu faire d’autre. Aujourd'hui, après avoir participé à la mission Mars Exploration Rover de la NASA, elle dirige le Centre de recherche Carl Sagan de l'Institut SETI aux États-Unis, une organisation scientifique à but non lucratif qui cherche à comprendre et expliquer l'origine de la vie dans l'univers et l’évolution de l’intelligence. Mais elle est aussi une exploratrice des milieux extrêmes terrestres qu’elle étudie comme analogues à Mars au début de son histoire. Dirigeant des expéditions scientifiques de haute altitude dans les Andes, elle plonge dans des lacs comme celui du volcan Licancabur à près de 6 000 mètres pour comprendre si la vie a pu apparaître sur Mars et y laisser des traces.À travers ses expéditions, elle tente de répondre à des questions qui nous habitent tous : y a-t-il une vie au-delà de la Terre ? Qu’est-ce que la vie ? Mais si son regard tourné est vers les étoiles, cela ne l'empêche pas de considérer le changement climatique comme une priorité de sa recherche. Un plaidoyer pour une compréhension du monde et de l’univers comme un tout vivant.Voyage aux frontières de la vie présente un renversement de perspective : chercher sur la Terre les conditions d’une vie ailleurs. Vertigineux et dépaysant ! Le récit d’un parcours passionnant, exaltant, exemplaire. Au-delà de cette quête dans l’espace au travers de missions planétaires ou sur Terre dans des milieux extrêmes, c’est aussi l'histoire d’une exploration de soi-même.

Quando Einstein passeggiava con Gödel

Science & Nature

Il momento della giornata preferito da Albert Einstein a Princeton era la passeggiata per tornare a casa dall'Institute for Advanced Studies, dove era considerato una celebrità. A rendere la camminata ancora più gradita fu l'arrivo dall'Europa, nei primi anni Quaranta, di un collega eccentrico e bizzarro, che a molti appariva sospetto. Si trattava di Kurt Gödel, un logico e matematico austriaco sconosciuto al pubblico ma ammirato dagli scienziati di tutto il mondo. Einstein amava quelle chiacchierate in tedesco, e coloro che li osservavano lungo la strada, probabilmente, avrebbero voluto sapere cosa ci trovasse di tanto interessante in un personaggio così inavvicinabile, annichilito dal terrore di essere avvelenato dai gas del frigorifero. Che cosa li appassionava tanto? La politica, la teoria quantistica, la relatività?Ispirato dalle loro ipotetiche conversazioni e affascinato da questa insolita amicizia, Jim Holt, divulgatore scientifico di fama internazionale, ha raccolto i suoi saggi più brillanti scritti negli ultimi vent'anni per raccontare alcune tra le teorie e le scoperte più innovative in campo matematico, fisico e filosofico degli ultimi secoli: dal teorema dei quattro colori al panpsichismo, dai frattali all'infinitesimo, dalla macchina di Turing all'ipotesi di Riemann, dalla natura della verità all'illusione del tempo.I progenitori di questi concetti così disparati hanno tutti vissuto vite stravaganti, incredibili e spesso dall'esito tragico, come Sir Francis Galton, cugino di Darwin e primo eugenista della storia, che visse avventure strabilianti nell'Africa meridionale e affrontò re Nangoro, che si diceva fosse l'uomo più grasso del mondo. Le loro idee hanno tutte esercitato un'influenza fondamentale sul nostro modo di concepire la realtà, la conoscenza e la condotta morale: fisica, astronomia, matematica pura, metafisica e neuroscienze condividono una serie di domande su di noi e su come viviamo, ma anche la ricerca estenuante di risposte tanto plausibili ed efficaci quanto semplici e belle.In Quando Einstein passeggiava con Gödel la spigliatezza del filosofo e la disciplina dello scienziato, che contraddistinguono l'autore, si mescolano in una lettura sagace e al tempo stesso spassosa. Una vera e propria visita guidata in un museo cosmico, in cui ogni opera è introdotta da una guida preparata e capace di suscitare uno stupore genuino di fronte ai capolavori più sconvolgenti e misteriosi mai elaborati dall'uomo.Jim Holt, saggista, filosofo e giornalista statunitense, scrive di matematica, scienza e filosofia per «The New York Times», «The New Yorker», «The Wall Street Journal» e «The New York Review of Books». Il suo Perchè il mondo esiste? Una detective-story filosofica (2013) è stato un bestseller internazionale.

Śmiech ma po matce. Tajemnice genów

Science & Nature

Z tej książki dowiesz się:•Jak to się dzieje, że dziedziczymy florę bakteryjną?•Dlaczego wciąż nosimy w sobie geny odpornościowe neandertalczyków?•Jaką rolę w rozwoju genetyki odegrał groszek?•Kiedy XX + XY = XY, a kiedy XX?Wszystkim nam się wydaje, że z dziedziczeniem jesteśmy na ty. Już wiele wieków temu ludzie dostrzegali podobieństwa dzieci do rodziców – podobny kolor oczu lub sposób zachowania w określonych sytuacjach. Nie zastanawiali się jednak, dlaczego tak się dzieje, i nie nazwaliby tego dziedziczeniem. Dziedziczenie oznacza dar lub klątwę. Definiuje to, jacy jesteśmy, na podstawie naszej biologicznej przeszłości. Daje nam również nieśmiertelność, przenosi bowiem naszą cząstkę w przyszłość.Carl Zimmer, jeden z najbardziej uznanych amerykańskich naukowców, opowiada nam o historii dziedziczenia i genetyki od pierwszych chorób przenoszonych z pokolenia na pokolenie aż po czasy współczesne przyglądając się równocześnie swojej rodzinie. Wybiega również w przyszłość, zastanawiając się, w jakim stopniu etyczne jest modyfikowanie genów i pojedynczych komórek na wczesnym etapie rozwoju człowieka. Gdyby człowiek musiał przeczytać tylko jedną książkę o genetyce, powinien z pewnością sięgnąć po Śmiech ma po matce. Tajemnice genów Carla Zimmera. Książki dobre nie tylko w teorii!

Clean and Renewable Energy Production

Science & Nature

CLEAN and RENEWABLE ENERGY PRODUCTIONAccording to the World Renewable Energy Council (WREC), by the year 2100, the world's population will increase to 12 billion and the worldwide energy demand will increase steeply to about five times the present scenario. Researchers are striving to find alternative forms of energy, and this quest is strongly forced by the increasing worry over climate change and planetary heating. Among the diverse varieties of alternative energy sources, biomass has the singular advantage of being carbon neutral. The carbon that is discharged to the atmosphere during its exercise is read back during the utilization of biomass resources for energy output. Currently, biomass provides approximately 13% of the world's primary energy supply and more than 75% of global renewable energy. Indeed, it is estimated that bioenergy could contribute 25–33% of the global energy supply by 2050. Continued adoption of biomass will require efficient conversion rates and avoidance of competition with food and fibers.This book focuses on the recent practices in clean energy and renewable energy. The contributors highlight how newer technologies are reducing the dependency on non-renewable resources, benefiting the researchers who are working in the area of clean and renewable energy production. This new volume will also benefit mechanical engineers, electrical engineers, and bioengineers as they will be updated with the recent work progressing all over the globe. It will benefit the professionals working in the renewable energy sector such as solar, wind, hydrothermal, hydrogen, and bioenergy, including professors, research scholars, industry professionals, and students working in this field.
