“We can change. We are not desperate idiots of history, unable to take their destiny in their own hands. It has been told us for centuries. Many historical signs indicate that history is not an eternal circle where only the negative must triumph. Why should we renounce to this historical possibility and say: we give up, we cannot make it, sometime this world will come to an end. Exactly the opposite. We can construct a world as humanity has never seen before; a world that will distinguish itself for the absence of war and hunger. And this on the whole globe. This is our historical possibility, and we should let it go? I’m not a professional politician, but we are men who do not want the world to follow this way, and for this reason we will fight, we already started to fight…” Rudi Dutschke (1967)

From Physorg.com: “A group of three researchers from KEK, Shizuoka University and Osaka University has for the first time revealed the way our universe was born with 3 spatial dimensions from 10-dimensional superstring theory in which spacetime has 9 spatial directions and 1 temporal direction. This result was obtained by numerical simulation on a supercomputer. […]

I learned almost nothing about Chinese history when I went to school in Germany. In our times, it is really important to learn global history, and not just the history of our own countries or continents. The following short overview of Chinese dynasties is a frame for understanding at least the outline of Chinese history. […]

This is a simple computer-simulated rotation from a point, which has 0 dimensions, to a line (1 dimension), a square (2), a cube (3), all the way up to 6 dimensions, and then down. Multi-dimensional objects are much more complex than we can imagine.   Related posts: Tesseracts: from 3 to 4 Dimensions. Klein Bottle […]

The short video clip below shows the 3D rotations of a 4D object. The deeper questions concern the nature of a “dimension”. How do we know what a dimension is, and if we live in a 3D universe, could we possible also exist in a higher-dimensional universe? it is best to start with simple examples in order to train the mind to think about these questions. The clip below shows a tesseract, which is the four-dimensional analog of a cube. (In geomery, it is called a regular octachoron or cubic prism.) The tesseract is to the cube as the cube is to the square.

I found this picture in a power point presentation from Intel. Their newest chip,  Knights Corner, can do in 2011, what a super computer with  9298 cores, distributed over 72 cabinets, could do in 1997.  Where will we be in another 14 years?

I found this on Wikipedia, reading about prime numbers: “Inevitably, some of the numbers that occur in nature are prime. There are, however, relatively few examples of numbers that appear in nature because they are prime. One example of the use of prime numbers in nature is as an evolutionary strategy used by cicadas of […]
