This is a collection of unrelated short videos in the field of physics. ...Dont know what an isotope is? ...Much less how carbon-fourteen difers from carbon-twelve? Well let us show you how carbon-fourteen can tell you how long ago something died! And if that doesnt whet your apetite, ask yourself how we can get energy both from splitting atoms and from joining them together! This was not made by myself. It was made by the Cassiopeia Project. www.cassiopeiaproject.com "The Cassiopeia Project is an effort ot make science education videos available for free to anyone who wants them. We believe that if you ca visualise it, then understanding is not far behind. Teachers and stufdents are particularly welcome to use these materials." I want to make clear they say nothing about people who are not teachers and students not being allowed to use this, so I think Im okay. They also have a youtube channel with all this. www.youtube.com Please rate and comment.

www.artehistoria.jcyl.es A comienzos del siglo XI, la Península Ibérica se halla muy fragmentada en diferentes territorios. En la España musulmana, a la muerte de Almanzor, primer ministro del califa Hixam II, que había frenado el avance de los reinos cristianos, comienza la desintegración del califato y su fragmentación en pequeños reinos de taifas, como las grandes de Zaragoza, Lérida, Toledo, Badajoz, Sevilla, Córdoba y Murcia, acompañadas por otras de menor extensión.

Los árboles son poemas que la tierra escribe en el cielo, nosotros los cortamos y los convertimos en papel para dejar constancia de nuestra necedad. Para mí, la naturaleza es sagrada; los árboles son mis templos y los bosques son mis catedrales." Algunas fotografias son de Rarindra Prakarsa The trees are poems that the Earth writes in the sky. We cut them and converted them in paper, to be able to leave witness of our foolishness For me, the nature is holy; the trees are my temples and the forests are my cathedrals." With photograps of Rarindra Prakarsa

Science & Reason on Facebook: tinyurl.com Physics (Chapter 3): Gravity, Branes And Hidden Dimensions (The Fourth Dimension / 4D Tesseract) --- Subscribe to Science & Reason: ? www.YouTube.com ? www.YouTube.com ? www.YouTube.com ? www.YouTube.com --- Why is gravity so weak? Why can a small magnet pull or push something away from the entire earth? There is an idea that may explain it, but before we go there, lets explore some preliminary ideas. The most popular quantum gravity theory of today describes all fundamental particles as vibrating strings of energy. And the theory is constructed in a whopping nine or ten spatial dimensions instead of the three that we experience in our everyday lives. But what is a dimension? A line is a familiar geometric figure. It can be completely described by giving its length. It is a one-dimensional object. It can be imagined that the dimensionality of an object can be created by taking an object of one less dimensions and moving it at a right angle to that dimension. You can create a line in your imagination by thinking of taking a point and moving it. Next consider a surface: A surface is also quite familiar. A surface has both length and width and requires two measurements to define it and therefore is a two-dimensional object. Similar to the generation of a line from a point, we can generate a two-dimensional surface by taking a line and moving it in a direction other than the direction of its length. And a solid figure is the stuff of ...
