Lleno de anécdotas divertidas, Neil deGrasse Tyson explica con claridad qué son las estrellas enanas, los agujeros negros, los quásares y las posibilidades de que no estemos solos en el universo.Tambien habla de la imposibilidad de viajar mas rapido que la luz y de la esperanza de encontrar los agujeros de gusano, que nos permitirian conocer otros mundos.Desde que era niño, a Neil deGrasse Tyson le encantaba mirar las estrellas, asi que para comprarse su primer telescopio se dedico a pasear perros en el Bronx, el barrio de donde es originario. Su afan de conocimiento no se detuvo ahi: fue aumentando a medida que descubria nuevas cosas, como los anillos de Saturno o de donde viene cada uno de los elementos de la tabla periodica.Y ese afan no se detiene, porque la astrofisica es una ciencia que todos los dias descubre algo nuevo: un asteroide, un planeta, una galaxia.

A la mayoría nos gustan las matemáticas, el problema es que no lo sabemos. La historia de las matemáticas fue escrita por hombres y mujeres con un intelecto sorprendente, pero no se equivoquen: los verdaderos heroes de esta gran novela son las ideas. Esas pequeñas ideas que germinan un dia y se propagan de un siglo a otro, las que nos dicen que hay un mundo de impresionante riqueza justo delante de nuestros ojos.Junto con Mickael Launay, descubriremos que las matematicas son hermosas, poeticas, sorprendentes, emocionantes y estimulantes. El numero Pi es fascinante. La sucesion de Fibonacci y el numero aureo nos llevan por caminos inesperados donde se unen el arte y la naturaleza. Las ecuaciones son un desafio y tambien representan el infinito universo matematico.Si nunca llegaste a comprender las matematicas. Incluso si las llegaste a odiar... ¿Que te pareceria darles una segunda oportunidad? ¡Te sorprenderas!

¿Quién inventó el número cero? ¿Por qué hay 60 segundos en un minuto? ¿Cómo es de grande el infinito? ¿Dónde se cruzan las líneas paralelas? ¿Es cierto que el aleteo de una mariposa puede causar una tormenta en la otra punta del mundo?50 cosas que hay que saber sobre matematicasdesgrana uno a uno los cincuenta conceptos matematicos -antiguos, modernos, cotidianos y esotericos- que nos permitiran entender y dar forma al mundo que nos rodea.

La vida de las abejas, «un mundo aéreo, optimista y exterior», es estudiada por el poeta con ciencia y paciencia de entomólogo y con exactitud e ingenio, el escritor observa la vida dentro y fuera de

Air pollution affects us all in a number of crucial ways, causing lasting damage to our health and our environment. While primary pollution can result from local activities, the extent of the impact can be felt at spatial scales from the individual up to the whole planet and temporal scales from minutes to decades. Consequently, pollution of our atmosphere remains a critical concern, warranting continued scientific investigation and the development of effective local and global solutions. The World Atlas of Atmospheric Pollution clearly and engagingly summarises current understanding of the state of air pollution on city to global scales.

This book is a tribute to Professor Pedro Gil, who created the Department of Statistics, OR and TM at the University of Oviedo, and a former President of the Spanish Society of Statistics and OR (SEIO). In more than eighty original contributions, it illustrates the extent to which Mathematics can help manage uncertainty, a factor that is inherent to real life. Today it goes without saying that, in order to model experiments and systems and to analyze related outcomes and data, it is necessary to consider formal ideas and develop scientific approaches and techniques for dealing with uncertainty

Harmful algal blooms HABs blooms that cause fish kills contaminate seafood with toxins or cause human or ecological health impacts and harm to local economies are occurring more often in more places and lasting longer than in past decades This expansion is primarily the result of human activities through increased nutrient inputs and various aspects of climate change The Global Ecology and Oceanography of Harmful Algal Blooms GEOHAB programme promoted international collaboration to understand HAB population dynamics in various oceanographic regimes and to improve the prediction of HABs This volume introduces readers to the overarching framework of the GEOHAB programme factors contributing to the global expansion of harmful algal blooms the complexities of HABs in different habitats and the forward looking issues to be tackled by the next generation of GEOHAB GlobalHAB The programme brought together an international team of contributingscientists and ecosystem managers and its outcomes will greatly benefit the international research community

This book documents the effects of natural hazards on coastal ecosystems in detail The sea is an indispensable component of the Earth system and human societies obtain many goods and services from the marine environment Global warming threatens marine ecosystems through seawater temperature rise acidification sea level rise and the increased frequency of severe storms The repeated effects of tsunamis also have major impacts on coastal ecosystems Increases in population and industry activities along the coast cause the degradation of coastal ecosystems through direct and indirect uses of the environment such as reclamation overexploitation of bioresources and pollution Given these facts we need to improve our understanding of the physical chemical and biological mechanisms characterizing marine ecosystems in order to better measure the effects of anthropogenic and natural impacts on the sea and its ecosystems Equipped with a comprehensive understanding of the sea including the effects of the main pressures on it we will have a better idea of the future state of the sea based on several scenarios of global warming The 16th France Japan Symposium on Marine Science focused on using advances in oceanography to better understand the current status of the sea

Quantum Optics for Engineers provides a transparent and methodical introduction to quantum optics via the Dirac's bra-ket notation with an emphasis on practical applications and basic aspects of quantum mechanics such as Heisenberg's uncertainty principle and Schrodinger's equation. Self-contained and using mainly first-year calculus and algebra tools, the book: * Illustrates the interferometric quantum origin of fundamental optical principles such as diffraction, refraction, and reflection * Provides a transparent introduction, via Dirac's notation, to the probability amplitude of quantum entanglement * Explains applications of the probability amplitude of quantum entanglement to optical communications, quantum cryptography, quantum teleportation, and quantum computing. Quantum Optics for Engineers is succinct, transparent, and practical, revealing the intriguing world of quantum entanglement via many practical examples. Ample illustrations are used throughout its presentation and the theory is presented in a methodical, detailed approach

Nowhere on Earth is the challenge for ecological understanding greater, and yet more urgent, than in those parts of the globe where human activity is most intense - cities. People need to understand how cities work as ecological systems so they can take control of the vital links between human actions and environmental quality, and work for an ecologically and economically sustainable future. An ecosystem approach integrates biological, physical and social factors and embraces historical and geographical dimensions, providing our best hope for coping with the complexity of cities.This book is a first of its kind effort to bring together leaders in the biological, physical and social dimensions of urban ecosystem research with leading education researchers, administrators and practitioners, to show how an understanding of urban ecosystems is vital for urban dwellers to grasp the fundamentals of ecological and environmental science, and to understand their own environment.
