Todos hemos oído hablar de la física cuántica, aunque realmente no sepamos ni qué es ni para qué sirve. Hasta hace poco, ni siquiera los físicos parecían tenerlo demasiado claro.En las últimas décadas se ha aprendido algo mas, y ahora sabemos que la fisica cuantica no va de particula y ondas, ni de "cosas que hacen cosas raras", sino que es una teoria sobre la propia informacion, sobre el espacio y el tiempo, sobre las relaciones entre causa y efecto, y sobre el conocimiento en si mismo.

Por primera vez se reúnen en un libro los escritos místicos de los científicos más eminentes de nuestra era, los padres fundadores de la Relatividad y de la Física Cuántica. Todos ellos, con un lenguaje asequible y ajeno a la terminologia tecnica, expresan su conviccion de que la fisica y la mistica, de alguna manera, son complementarias.Ciertamente, el autor de la compilacion, Ken Wilber, nos previene contra la ya abusiva tendencia a ligar la suerte de la mistica con el nuevo paradigma de la ciencia. Son cosas diferentes que, precisamente en tanto que diferentes, pueden convivir. Pero queda intacta una pregunta: ¿que fue lo que llevo a cientificos tan diversos a compartir una vision mistica de la realidad? Ello es que Heisenberg, Schroedinger, Einstein, Jeans, Planck, Pauli, Eddington, todos, sin excepcion, acabaron teniendo una concepcion trascendente del mundo donde la dualidad entre materia y espiritu quedaba sobrepasada. Y que esta concepcion les vino como remate de una postura critica y no irracional.Nos encontramos, pues, ante el aspecto mas hondo y apasionante de la ciencia de nuestro tiempo. La aventura intelectual mas fascinante contada por sus protagonistas mas preclaros.

Establecer los principios fundamentales de la Física con claridad y precisión es una misión de los textos de Física general. Pero normalmente esto no basta para entender la Física. Es necesario ilustrar estos principios con ejemplos sobre sus aplicaciones y los textos generales no pueden recargar excesivamente sus paginas con el numero necesario de ejercicios, cuestiones y problemas.Este es en lineas generales el proposito de los autores al escribir este libro.Completar la formacion del alumno de Fisica de la Universidad o Escuelas Tecnicas mediante una exposicion de cuestiones, ejemplos e ilustraciones tomadas en su mayor parte de la vida real.

Marie Curie fue un ejemplo para las mujeres que luchaban por el reconocimiento y la independencia y su contribución a la ciencia le mereció con dos premios Nobel. Su trabajo sobre la radioactividad amplio nuestros conocimientos de la fisica nuclear y produjo enormes avances en el tratamiento del cancer, pero los peligros inherentes a su trabajo eran desconocidos."Curie y la radiactividad" presenta una brillante instantanea de la vida y la obra de Marie Curie y ofrece una explicacion clara y accesible del significado e importancia del descubrimiento de la radioactividad y de las implicaciones que ello tendria para la vida en el siglo xx y el futuro.

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: 5/5All 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.

This is an adventure that began almost fourteen billion years ago, one that so often threatened to fail. Its truly a miracle Im still here. Despite everything, I wouldnt have wanted to miss one second of it. And the best is yet to come.With the help of an extraordinary narrator, youre invited to discover the wonder and drama of the history of the cosmos. In this story we follow the journey of one proton who comes into existence at the beginning of creation and makes it all the way through history to today. By becoming a part of atoms and molecules that turn up at some of the universes most important moments, our friend Proton witnesses emerging galaxies, the origin of life, its evolution into a wild diversity of life forms, the first human beings, the birth and life of Jesus, the beginnings of the Christian church, all the way up to the present day. Through it all, the mysterious, seemingly unbelievable plans of the Creator continue to unfold. . . .Combining its authors mind-bending scientific knowledge, storytelling skills, and insights from theology, Dawn provides a fresh look at the fundamentals of cosmology, evolutionary biology, and the good news of God in one overarching adventurein the form of a gripping story. Readers who love both science and Scripture will discover an engaging, thought-provoking tale that reminds us we each have a big place in Gods plan of creationeven if were very, very small.BioLogos Books on Science and Christianity invite us to see the harmony between the sciences and biblical faith on issues including cosmology, biology, paleontology, evolution, human origins, the environment, and more.

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.

The analyzes carried out by artificial intelligence must start from a complete and integrated data structure, which is classified and grouped with the intention of synergistically producing mental and predictive captures. In this perspective, the objective of this study is to analyze the possibility of contribution of artificial intelligence in guiding decision-making in the public planning of sustainable electrical matrices. The methodological procedures of this investigation, built a structure of analysis of electricity sources, based on the economic, social, environmental and technological dimensions; as well as a sectoral analysis structure of energy sustainability indicators, supported by linear correlations of an economic, social, environmental and political nature. The planning of electrical matrices, according to the inferences of this investigation, can use artificial intelligence as a strategic guide for decisions, as long as they are based on analysis structures focused on the strategic use of electricity sources and the use of sectoral and multidimensional indicators. This investigation constitutes an original contribution insofar as it discusses the possibilities of connections between artificial intelligence and the construction of electrical matrices, from the perspective of improving the decision-making process in Brazilian public planning. The discussion about these connections helps to raise subsidies for machine learning to process and develop methodologies, based on algorithms, that automate the construction of decision analysis models in the planning and sustainable construction of the use of electricity.
