As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects, and plans for high-tech hardware that could deflect an incoming object from a collision course a procedure depicted, with little regard for scientific accuracy, in several Hollywood movies. Astrophysicist and science writer Andrew May disentangles fact from fiction in this fast-moving and entertaining account, covering the nature and history of comets and asteroids, the reason why some orbits are more hazardous than others, the devastating local and global effects that an impact event would produce, and more optimistically the way future space missions could avert a catastrophe.

No resulta difícil imaginar a nuestros ancestros contemplando admirados el maravilloso cielo nocturno. Y fue ya en la Antigüedad cuando empezaron a elaborarse las primeras teorías sobre los component

Hay demasiados libros que prescinden del mundo y al mismo tiempo pretenden describírnoslo. Este olvido nihilista del cosmos me parece más determinante que el olvido del ser. Los monoteístas han entronizado un libro que pretendia decir la totalidad del mundo. Para ello han ignorado muchos libros que expresaban el mundo de forma distinta a la de ellos. Se ha instalado una inmensa biblioteca entre los hombres y el cosmos, la naturaleza, lo real.Michel OnfrayEste es el punto de partida de Cosmos, primer volumen de una trilogia titulada Breve enciclopedia del mundo, en la que Michel Onfray presenta una filosofia de la naturaleza que ha cautivado a miles de lectores en Francia. Onfray nos propone una meditacion filosofica en contacto directo con el cosmos. Contemplar el mundo, recuperar las intuiciones fundadoras del tiempo, de la vida, de la naturaleza, comprender sus misterios y las lecciones que nos proporciona. He aqui la ambicion de esta obra personalisima, que enlaza con el ideal griego y pagano de una sabiduria humana en armonia con el mundo.

I continue my saga of investigating the world, feelings, animals, plants and other living beings looking for traces that indicate that all of this is not before our eyes by accident, by blind, random and stupid evolution, but that the world reveals that there is a brilliant mind who designed it and who created natural laws to make the great mechanism of the universe work automatically. We clearly realize that there are millions or billions of gears that make the universe work. We cannot talk much about the universe because our knowledge is minimal about the celestial bodies and the possible creatures that infest the infinite. But planet Earth has a variety of species of life that is astounding. While scientists are looking for some trace of life in the universe, even if it is bacteria, here on Earth there are so many species of life that we have not yet cataloged them all. But all creatures have peculiar characteristics and embedded biological technologies that can only have arisen because they were created in God s space laboratory. I m absolutely sure that we are like worms in God s stomach, worms don t understand men, and men don t understand God. But I don t think it takes much reasoning to understand that so many technologies embedded in living beings are products of all types of engineering projects. God holds the secrets of life, and that is what I seek to show in this fourth volume of creationist biology.

La NASA está en un punto crítico; después de décadas de supremacía mundial, canceló su programa de transbordadores cerrando su acceso al espacio. Hasta 2020, ningún astronauta será lanzado fuera de la orbita terrestre desde suelo estadounidense, y pronto su programa espacial podria ser eclipsado por el de otros paises.Con su caracteristico humor y sus provocadoras ideas, Neil deGrasse Tyson, el celebre presentador del programa Cosmos, ilumina el pasado, el presente y el futuro de la exploracion del espacio y nos recuerda de manera brillante por que la NASA importa mas que nunca.Estas cronicas son una lectura provocadora y agil que representan lo mejor del pensamiento del autor y reflexionan sobre temas tan diversos como la literatura cientifica y los tropiezos de las misiones espaciales, brindando una vision del futuro necesaria, clara y, sobre todo, inspiradora.

Clear and compact ... Its hard to fault as a brief, easily digestible introduction to some of the biggest questions in the UniverseGiles Sparrow, BBC Fours The Sky at Night, Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That something is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

Ao longo da história, encontramos grandes pensadores, cientistas e inventores que, num rompante criativo, desafiam nossos paradigmas e nos atiram sem piedade a uma nova realidade, que a princípio pode parecer desconfortavel, incompreensivel ou ate questionavel.Mas, afinal, de onde surgem as grandes ideias?Ao tomar como exemplo cientistas e inventores que mudaram nosso modo de viver, Larissa Santos expe alguns dos elementos essenciais para acender as centelhas da criatividade. Desmistificando a viso romantica do genio solitario e da inspiraço divina, esta obra revela que boas ideias no surgem do nada, mas so fruto de um processo de construço e reformulaço das experiencias acumuladas ao longo da vida, e que dependem absolutamente de tempo, contexto e, por que no, uma pitada de acaso.Compreenda o fascinante mundo das mentes criativas, e deixe-se inspirar para um futuro de inovaçes transformadoras.

La Mitología Clásica son lo suficientemente atractivos y formativos per se como para abarcar la duración de uno o dos cursos. Este libro, apoyándose en tal afirmación, pretende, por un lado, atraer al del 2º ciclo de la ESO e incluso del Bachillerato, al maravilloso mundo de la Mitologia Clasica y, por otro lado, facilitar al profesor de Cultura Clasica un instrumento didactico util y fructifero con respecto a su tarea docente.Este libro, fruto de la experiencia docente con alumnos del 2º ciclo de la ESO principalmente, tiene como objetivo, didactico fundamentalla ptenciacion de la comprension lectora y de la expresion y escrita, junto con la adquisicion de los referentes clasicos necesarios, que faculten al estudiante el acceso a una formacion cultural tanto basica como superior.Se intenta conseguir, mediante este libro, que el alumno, a traves del placer de la lectura y bajo la sabia direccion del profesor, transite desde un posible vacio, confusion, oscuridad o desorden hacia el orden, la luz, la claridad y el conocimiento que porpociona la Mitologia Clasica. De ahi el titulo DEL CAOS AL COSMOS.Este libro se divide en dos partes: una de contenidos conceptuales (aprendizaje de saberes, datos, hechos y conceptos) y actitudinales (actitudes, valores y normas de cara a formar personas en el ambito familiar, laboral y social); y otra de contenidos procedimentales (adquisicion y desarrollo de destrezas, habilidades, estrategias y tecnicas).Estos contenidos se aprenden, basicamente, a traves de la lectura, el analisis y el comentario de texto ya que el conocimiento del mundo clasico se ve altamente favorecido por el contacto con los textos originales de los autores clasicos.Debido a que en todo grupo hay alumnos con diferentes capacidades, intereses y actitudes, los contenidos de este libro se han incardinado atendiendo a los siguientes criterios metodologicos:Abundancia de contenidos procedimentales, segun su dificultad unas actividades pretenden conseguir objetivos minimos, esenciales, y otros objetivos mas ambiciosos, es decir, de refuerzo, profundizacion o ampliacion.Graduacion de los contenidos, de lo facil a lo complejo, de lo esencial a lo complementario.Recurrencia de los contenidos, es decir, insistencia periodica en el aprendizaje de los conceptos, procedimientos o actitudes fundamentales.

La aparición de dos teorías de la física moderna: la mecánica cuántica y la relatividad, cambiaron radicalmente las ideas que se tenían sobre la materia y la energía, la fuerza, el tiempo y el espacio. Otro cambio radical se produjo con el descubrimiento de la expansion del Universo. Esta obra reseña la relacion entre lo atomico y lo cosmico, entre las propiedades de la materia y la cosmologia moderna.

En los últimos años se ha descubierto que el sistema solar externo es mucho más complejo de lo que imaginábamos, pues su estructura resulta ser más intrincada que la del Sol, los nueve planetas, los satelites, los asteroides y los cometas. En este libro se presenta, en un formato de articulos breves, una vision contemporanea del sistema solar. Se describen las caracteristicas mas relevantes del Sol, los planetas y los objetos menores que han marcado un hito en el conocimiento de nuestro sistema planetario.

A astronomia é um exercício de humildade e reconhecimento de que pouco conhecemos sobre o Universo. Estamos avançando na tentativa de desbravar o Cosmos e temos que começar do nosso lar: o Sistema Solar. A invenço do telescopio foi um divisor de aguas e ajudou a humanidade a desbravar sua vizinhança e alem. Porem, apenas observar de longe no era suficiente para saciar a curiosidade humana. Sempre se desejou ir alem. Antigamente, olhavamos para os ceus e viamos pontos de luz sem imaginar o que ocorria nas vizinhanças desses objetos. Com os avanços tecnologicos podemos vislumbrar quais fenomenos ocorrem ali e, o mais intrigante, podemos enviar sondas espaciais para investigar outros Mundos. Escrito por Fernando Henrique Martins e Jose Leonardo Ferreira, dois entusiastas das ciencias espaciais, este livro leva, de maneira instigante, o leitor a uma viagem pelo Sistema Solar com a sonda planetaria Cassini-Huygens, mais especificamente a Saturno, que e um dos pontos brilhantes que o ser humano percebe no ceu. E mostra algumas das fantasticas descobertas que essa sonda espacial conseguiu fazer, cujos sensores se somaram aos olhos do ser humano para ampliar o entendimento humano acerca do Sistema Solar. Essa sonda revelou detalhes de Saturno que nunca haviam sido observados a partir da Terra. Ate mesmo os voos da imaginaço humana no foram capazes de idealizar as maravilhas escondidas nesse planeta.

Una visión distinta del juego del universo.La curiosidad por saber qué es el universo me llevó a su estudio, mostrando una realidad que no se ha analizado desde este nuevo punto de vista, como es el porque de la forma y composicion de sus conjuntos ordenados. Hasta ahora, las descripciones que se han realizado para explicarlas han sido desde el punto de vista mecanico, basadas en los Principios Matematicos de la Filosofia Natural expuestos por Isaac Newton. Sin embargo, ellas no explican de manera explicita por que, en el nucleo de estos sistemas, que representan el 0,00001 % del volumen total, se encuentra el 99,9 % de la materia newtoniana, mientras que, en la corteza, que representa el 99,9999 % de su volumen, esta ocupada por una oscura entidad llamada espacio. Este orden desperto en mi mas interes al conocer la estructura de los llamados elementos quimicos, propuesta por Rutherford, en la que expreso una disposicion, composicion y proporcion semejante a la de los citados macrosistemas. Sin embargo, estudios posteriores llevaron a la conclusion de que las mecanicas que explican ambas estructuras no son las mismas. Fue la evolucion que sufren los microsistemas, asi como la filosofia que nace de la Teoria General de la Relatividad y de la Fisica Cuantica, lo que me llevo a concluir lo que se presenta en esta exposicion de ideas.
