Alba Moreno, divulgadora científica de referencia en redes, te explica las leyes de la física de manera rigurosa y tremendamente sencilla.¿Por qué el cielo es azul? ¿Hay física cuántica en nuestros ordenadores? ¿Alguna vez te has preguntado como funciona el wifi? ¿Sabes que los agujeros negros pueden llegar a evaporarse?Estas y otras preguntas son las que la fisica Alba Moreno nos plantea en su primer libro, La vida es fisica.La autora habla en el de lo que no se puede ver, del mundo subatomico, asi como de la aplicacion practica que ese universo en miniatura tiene. Tambien nos adentraremos en lo que podemos ver, la luz y la electricidad. Igualmente, nos deslumbraremos con las distintas historias en torno al big bang, la teoria de la relatividad y los agujeros negros.Ademas, el libro esta atravesado por pildoras sobre la historia de la fisica, casos practicos y ejemplos cotidianos que nos terminaran de convencer de una vez por todas de lo facil que puede ser la fisica, desde los atomos hasta los confines del universo.

A Olimpíada Brasileira de Física das Escolas Públicas (OBFEP) é um programa permanente da Sociedade Brasileira de Física (SBF), com o apoio financeiro do Conselho Nacional de Desenvolvimento e Tecnologico (CNPq). A OBFEP teve inicio em 200, ainda em carater de projeto piloto nos estados da Bahia, Goias, Piaui e So Paulo e em 2011 foi aplicado para os estados do Maranho e Mato Grosso. Em nivel nacional, a OBFEP teve inicio em 2012 e permanece anualmente sendo realizada ate os dias atuais. Apenas em 2020, devido a pandemia de COVID-10, no houve ediço. A OBEFEP e destinada exclusivamente a estudantes do ensino medio e do ultimo ano (9º ano) do ensino fundamental de escolas publicas.

g_{ww} y g_{\mu w} , lo que afecta directamente las geodésicas y los fenómenos gravitatorios.2. Ecuaciones de Campo de Einstein ExtendidasLas ecuaciones originales de Einstein son:G_{\mu\nu} + \Lambda g_{\mu\nu} = 8 \pi T_{\mu\nu}donde G_{\mu\nu} es el tensor de Einstein, \Lambda la constante cosmologica y T_{\mu\nu} el tensor energia-momento.En 5 dimensiones, estas se generalizan a:G_{AB} + \Lambda g_{AB} = 8 \pi T_{AB}donde G_{AB} es el tensor de Einstein extendido.El tensor de Ricci y la curvatura escalar se calculan ahora en un espacio de 5 dimensiones:R_{AB} = \partial_C \Gamma^C_{AB} - \partial_A \Gamma^C_{CB} + \Gamma^C_{CD} \Gamma^D_{AB} - \Gamma^C_{AD} \Gamma^D_{CB}R = g^{AB} R_{AB}El nuevo termino \Gamma^C_{AB} , la conexion de Christoffel, incluye derivadas de g_{\mu w} y g_{ww} , introduciendo acoplamientos adicionales entre el espacio-tiempo y la dimension w .

"Isaac Newton was a shy, quiet boy growing up on a farm in England 300 years ago. He was not a very good student and nobody paid much attention to him. Nobody that is, except the school bully. One day the bully punched Isaac in the stomach. That hurt, and that got Isaac very mad! He pulled himself up straight and fought back. Isaac pushed the bully onto the ground and rubbed his face in the mud. All the other kids hated the bully and came and cheered for Isaac.So Isaac taught the bully a lesson, but he wasnt satisfied with that. Now that he knew he could fight better than the bully, he wanted to prove that he could do anything better than the bully. So he started paying attention to school and studying hard. He was soon the top of his class, proving he was smarter than the bully too.Isaac Newton kept on studying and when he grew up he became a math professor at Cambridge University. He discovered lots of important things and is one of the most famous scientists who ever lived.But One day Isaac was reading a book under an apple tree on the farm. An apple fell out of the tree - bonk! Ow!Now, for most people that would be the end of the story, but not for Isaac. Not for somebody who just couldnt stop asking why all the time.Why did the apple fall out of the tree? Does everything fall? What makes things fall? Can anything stop things from falling? Are the sun, moon, and stars falling? Why dont they ever hit the ground?So many questions. Newton spent many years answering these questions by thinking and doing experiments. He made up the law of gravity. According to this law everything pulled everything else to itself by a force called gravity. How strong that force is depends on how heavy the things are and how close together..This book telling this excellent biographic story very simple, teaching and amazingly.."

"She is both dead and alive according to some left brains. But I want to give you the story of what we can learn from this for everyday life and for our work with the daily nature plilosophical system." As you know I was the first that told the world that all the new systems that give themselves very good sounding names like "Quantum worlds, theories" or "Nonlinear or Discrete physics" systems are all random number generators including. Now what is missing in our culture is an appreciation for the "Uncertain" but that this will be the foundation of a new science and that is what we are doing here. For about one hundred years the uncertainty principle has been reconfirmed in hundreds of experiments, which simply says you cannot measure all parameters like coordinates, impulse and so on of atomic particles with any desired accuracy but that there is a limit given by the Heisenberg formula. Why has such a tiny matter kept so many brains spinning for such a long time what is in question here are quantities in the range of 1/billions of a meter and 1/ billions of a secondso who and why care? We all know or should know that "uncertainty" is a common factor in our life and we try to escape it with so much pretense and insurances. This is why the discovery that "uncertainty" is even part of the most simple processes is making so much wind for such a long time. And of course there are those simple minds like Einstein who hold that the "Uncertainty principle" is only the result of the fact that we do not know all the details he called them "the hidden Parameters" and once we know them "voila" no more uncertainty all is calculatable down to the last digit. Simply our common hope/believe/imagination that at the basis there is a really real reality that is unmistakable one way or the other The cat is either alive or dead.." I dont want to bore you with the over and over told stories of the wave-particle duality and Schroedingers cat May be there are hundreds of books that do this. But I tell you a different and deeply story so relation to the paralel universe that contain from ancient Upanishads to modern String theory and beyond with simply forming "Four Equations" and "Four Stories"..

Desde la Antiguedad hasta el siglo xx , treintaiun relatos narran la sorpresa y la inquietud por los fenomenos del universo y los decisivos instantes vividos por algunos hombres de ciencia: Arquimedes, Eratostenes, Ptolomeo, Nicolas Copernico, Tycho Brahe, Giordano Bruno, Johannes Kepler, Galileo Galilei, Isaac Newton, Christiaan Huygens, James Clerk Maxwell, Francisco Jose de Caldas, Urbain Le Verrier, Leon Foucault, Carl Gustav Jakob Jacobi, Ernst Mach, Max Planck, Albert Einstein, Ludwig Boltzmann, Hermann Minkowski, Niels Bohr, Erwin Schrodinger, Paul Dirac, Edwin Hubble, Enrico Fermi, Robert Oppenheimer, Yang Chen-Ning y Tsung-Dao Lee.

El presente texto presenta los fundamentos del análisis exergético y sus aplicaciones. La intención de los autores al redactarlo ha sido tender el arco que va desde su raíz en las leyes de la Termodinamica hasta las aplicaciones mas usuales. Por ello, se ha combinado en el enfoque del libro el tratamiento sistematico de los conceptos con la presentacion de ejemplos resueltos.

Las preguntas mencionadas en el Título del libro son ampliamente conocidas por alumnos y profesores, pero aquí tienen seis características distintivas que las diferencias de las encontradas en la mayoria de los libros de textoLa cantidad (Aqui hay miles, y en los textos o no hay, solo hay algunas pocas decenas en los libros mas destacados en este aspecto)Todas tienen respuesta (En los escasos textos que tienen pregunta, o no tiene respuesta, o no sobrepasan el 10 % de ellas con respuestas)Estan categorizadas por su Grado de Dificultad Academico (Esto, sencillamente, no existe en ningun texto)La inmensa mayoria son ineditas (mas del 95%) (Solo no lo son las que se refieren directamente al enunciado de conceptos, definiciones, leyes, teorias, etc., o sea, las heredadas por la sociedad de la cultura universal)Las preguntas del primer epigrafe de cada capitulo tienen dos propositos diferentes (sirven, en general, para repasar el contenido teorico que aborda el capitulo pero ademas, pueden ser utilizadas para aproximarse por primera vez al contenido del capitulo)Las preguntas de cada capitulo en general, pueden utilizarse para tres propositos diferentes, (aprender desde cero un determinado contenido; repasar lo que ya se sepa; incrementar conocimientos independientemente del nivel que se tenga en la asignatura).
