[View \| Download]	Método Científico y Pensamiento Crítico By enyitornados El MÉTODO CIENTÍFICO es el "proceso de conocimiento caracterizado por el uso constante e irrestricto de la capacidad crítica de la razón, que busca establecer la explicación de un fenómeno ateniéndose a lo previamente conocido, resultando una explicación plenamente congruente con los datos de la observación". Pasos (según Francis Bacon): 1. Observación: Observar es aplicar atentamente los sentidos a un objeto o a un fenómeno, para estudiarlos tal como se presentan en realidad. 2. Inducción: La acción y efecto de extraer, a partir de determinadas observaciones o experiencias particulares, el principio particular de cada una de ellas. 3. Hipótesis: Planteamiento mediante la observación siguiendo las normas establecidas por el método científico. 4. Probar la hipótesis por experimentación. 5. Demostración o refutación (antítesis) de la hipótesis. 6. Tesis o teoría científica (conclusiones). Ver http://es.wikipedia.org/wiki/Metodo_c... PENSAMIENTO CRÍTICO (Nota: argumento = razón + conclusión). Inducir es un tipo de razonamiento en donde se obtienen conclusiones tan sólo probables. La inducción matemática es un caso especial, donde se va de lo particular a lo general y, no obstante, se obtiene una conclusión necesaria. Típicamente, el razonamiento inductivo se contrapone al razonamiento deductivo, que va de lo general a lo particular y sus conclusiones son necesarias. En otras palabras, un argumento deductivo existe cuando B puede estar lógicamente y necesariamente inferido de A. Sin embargo, la mayoría de los argumentos que uno se puede encontrar en la vida diaria son inductivos. Un pensador crítico debería entender que no importa como de fuerte es la evidencia que sostenga a un argumento inductivo ya que nunca probará su conclusión mediante un necesariamente o con una absoluta certeza (excepto en la inducción matemática). Es decir, el argumento inductivo solo prueba con cierto grado de probabilidad. Ver http://es.wikipedia.org/wiki/Pensamie...

THE BRAIN is an astonishing voyage of discovery into our last biological frontier. Although todays computers can make calculations in one-100th of a second and technology can transport us outside the bonds of Earth, only now are we beginning to understand the most complex machine in the universe. Using simple analogies, real-life case studies, and state-of-the-art CGI, this special shows how the brain works, explains the frequent battle between instinct and reason, and unravels the mysteries of memory and decision-making. It takes us inside the mind of a soldier under fire to see how decisions are made in extreme situations, examines how an autistic person like Rain Man develops remarkable skills, and takes on the age-old question of what makes one person good and another evil. Research is rushing forward. We've learned more about the workings of the brain in the last five years than in the last five thousand.

[View \| Download]	Evolución Biológica By enyitornados Evidencias a favor de la evolución: http://www.sesbe.org/sites/sesbe.org/... EVOLUCION VS CREACIONISMO - En definitiva, los argumentos principales de los creacionistas "científicos" hacen referencia a la corta edad de la tierra, que sería de tan solo unos 6.000 años de antigüedad, haciendo caso omiso de los métodos de datación radiométricos. Además, los restos fósiles serían muy recientes y los hombres habrían coexistido con los dinosaurios. Los fósiles son atribuidos al Diluvio universal, negando los principios más básicos y elementales de la Geología: actualismo, superposición de los estratos, etc., con lo cual todos los fósiles serían prácticamente de la misma edad. Asimismo, niegan todo aspecto geológico o palentológico que pueda estar en contradicción con la Biblia y que apoye la teoría de la evolución. Especial énfasis ponen en negar el valor de los fósiles para documentar la teoría de la evolución. Así atacan los resultados paleontológicos referentes a la existencia de los fósiles intermedios, tales como el Archaeopteryx y los homínidos primitivos, negando que existan formas intermedias. Sacan fuera de contexto el debate entre gradualistas y saltacionistas, ignorando que ninguno de los grupos cuestiona la teoría de la evolución, sino que simplemente discuten aspectos del mecanismo evolutivo. Y utilizan las pequeñas diferencias de los científicos para apoyar sus sensacionales afirmaciones. Ahora bien, a lo largo de este siglo se han descubierto numerosos fósiles que permiten reconstruir muchas lineas filogenéticas, y en lo que respecta a la filogenia humana en las ultimas décadas han aparecido muchos fósiles que permiten detallar como ha sido la evolución hasta llegar al Homo sapiens. Todo lo cual permite afirmar que los fósiles son el documento fáctico de la evolución. Pero, paradójicamente, ahora los antievolucionistas insisten en que los fósiles son uno de los principales problemas para la evolución. Así pues, en realidad sus argumentos son irracionales, no son plausibles ni acordes con los datos científicos y el creacionismo "científico" constituye una de las más típicas pseudociencias. Su interpretación literal de la Biblia les conduce a una ideología de tipo apocalíptico, involucionista e integrista. Confunden sus ideas con la realidad y no parecen tener los pies sobre la Tierra sino más bien en el "Cielo". Su ignorancia y falta de rigor se pone de manifiesto en sus frecuentes afirmaciones de que en todos los campos (Paleontología, Geología, Biología, etc.) se puede ver con toda facilidad que el evolucionismo no goza de ningún apoyo científico. La vieja estrategia de responder acusando de lo mismo que se les imputa les lleva a concluir que el evolucionismo es un mito, una religión y un fraude. Afirmaciones de este tipo se encuentran constantemente en sus publicaciones, lo cual evidencia que son unos ingenuos ignorantes o que mienten(ver http://wzar.unizar.es/perso/emolina/a... ).

Sagan, quien participo del proyecto Voyager 2, fue uno de los impulsores para que esta sonda, al abandonar nuestra galaxia, diera una vuelta sobre su eje y fotografia nuestro planeta. Con esta fotografia, Sagan reflexiona sobre lo diminuto que resulta nuestro planeta, y sobre las lecciones y significado que esta realidad debiera ser internalizada por cada uno de quienes habitamos, en este paseo momentaneo, la Tierrra.

The inspiration for Carl Sagans 1980 series, Cosmos, Jacob Bronowskis 1973 series, The Ascent of Man, alludes to and seeks to somewhat challenge the notion of some of Charles Darwins conclusions in The Decent of Man. Over the course of thirteen episodes, Bronowski travelled around the world in order to trace the development of human society through its understanding of science. Jacob Bronowski was one of a small group of men and women in any age who find all of human knowledge-the arts and sciences, philosophy and psychology-interesting and accessible. He was not confined to a single discipline, but ranged over the entire panorama of human learning. His book and television series, The Ascent of Man, are a superb teaching tool and a remarkable memorial; they are, in a way, an account of how human beings and human brains grew up together.

[View \| Download]	The Cosmic Perspective: Journey To The Edge Of The Universe By FFreeThinker "Of all the sciences cultivated by mankind, Astronomy is acknowledged to be, and undoubtedly is, the most sublime, the most interesting, and the most useful. For, by knowledge derived from this science, not only the bulk of the Earth is discovered ...; but our very faculties are enlarged with the grandeur of the ideas it conveys, our minds exalted above [their] low contracted prejudices." --James Ferguson, "Astronomy Explained Upon Sir Isaac Newtons Principles, And Made Easy To Those Who Have Not Studied Mathematics" (1757) --- Subscribe to Science & Reason: • http://www.youtube.com/FFreeThinker • http://www.youtube.com/Best0fScience • http://www.youtube.com/SagansCosmos --- The Cosmic Perspective Long before anyone knew that the universe had a beginning, before we knew that the nearest large galaxy lies two and a half million light-years from Earth, before we knew how stars work or whether atoms exist, James Ferguson's enthusiastic introduction to his favorite science rang true. Yet his words, apart from their eighteenth-century flourish, could have been written yesterday. But who gets to think that way? Who gets to celebrate this cosmic view of life? Not the migrant farmworker. Not the sweatshop worker. Certainly not the homeless person rummaging through the trash for food. You need the luxury of time not spent on mere survival. You need to live in a nation whose government values the search to understand humanity's place in the universe. You need a society in which intellectual pursuit can take you to the frontiers of discovery, and in which news of your discoveries can be routinely disseminated. By those measures, most citizens of industrialized nations do quite well. Yet the cosmic view comes with a hidden cost. When I travel thousands of miles to spend a few moments in the fast-moving shadow of the Moon during a total solar eclipse, sometimes I lose sight of Earth. When I pause and reflect on our expanding universe, with its galaxies hurtling away from one another, embedded within the ever-stretching, four-dimensional fabric of space and time, sometimes I forget that uncounted people walk this Earth without food or shelter, and that children are disproportionately represented among them. When I pore over the data that establish the mysterious presence of dark matter and dark energy throughout the universe, sometimes I forget that every day—every twenty-four-hour rotation of Earth—people kill and get killed in the name of someone else's conception of God, and that some people who do not kill in the name of God kill in the name of their nation's needs or wants. When I track the orbits of asteroids, comets, and planets, each one a pirouetting dancer in a cosmic ballet choreographed by the forces of gravity, sometimes I forget that too many people act in wanton disregard for the delicate interplay of Earth's atmosphere, oceans, and land, with consequences that our children and our childrens children will witness and pay for with their health and well-being. And sometimes I forget that powerful people rarely do all they can to help those who cannot help themselves. I occasionally forget those things because, however big the world is—in our hearts, our minds, and our outsize atlases—the universe is even bigger. A depressing thought to some, but a liberating thought to me. Consider an adult who tends to the traumas of a child: a broken toy, a scraped knee, a schoolyard bully. Adults know that kids have no clue what constitutes a genuine problem, because inexperience greatly limits their childhood perspective. As grown-ups, dare we admit to ourselves that we, too, have a collective immaturity of view? Dare we admit that our thoughts and behaviors spring from a belief that the world revolves around us? Apparently not. And the evidence abounds. Part the curtains of society's racial, ethnic, religious, national, and cultural conflicts, and you find the human ego turning the knobs and pulling the levers. Now imagine a world in which everyone, but especially people with power and influence, holds an expanded view of our place in the cosmos. With that perspective, our problems would shrink—or never arise at all—and we could celebrate our earthly differences while shunning the behavior of our predecessors who slaughtered each other because of them.

He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series "Cosmos: A Personal Voyage", which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history. A book to accompany the program was also published. He also wrote the novel "Contact", the basis for the 1997 Robert Zemecki's film of the same name starring Jodie Foster. During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, secular humanism, and the scientific method. http://www.carlsagan.com .
