Economic Manuscripts ( Karl Marx)

For an example of labour in common or directly associated labour, we have no occasion to go back to that spontaneously developed form which we find on the threshold of the history of all civilised races.^[31] We have one close at hand in the patriarchal industries of a peasant family, that produces corn, cattle, yarn, linen, and clothing for home use. These different articles are, as regards the family, so many products of its labour, but as between themselves, they are not commodities. The different kinds of labour, such as tillage, cattle tending, spinning, weaving and making clothes, which result in the various products, are in themselves, and such as they are, direct social functions, because functions of the family, which, just as much as a society based on the production of commodities, possesses a spontaneously developed system of division of labour. The distribution of the work within the family, and the regulation of the labour time of the several members, depend as well upon differences of age and sex as upon natural conditions varying with the seasons. The labour power of each individual, by its very nature, operates in this case merely as a definite portion of the whole labour power of the family, and therefore, the measure of the expenditure of individual labour power by its duration, appears here by its very nature as a social character of their labour.

What is the size of the Galaxy?

ScienceDaily (June 10, 2009) — Dark matter is an enigmatic energy that makes up most of the mass in the Universe, whose nature has not yet been identified. Researchers have succeeded in estimating the percentage of dark matter in the Universe and describing the processes related to the very existence of this matter. But, until now, no one has established the distribution and behavior of the dark matter in a galaxy.

Now, astronomers in the Theoretical Physics and Cosmos Department of the University of Granada, led by Eduardo Battaner, in collaboration with researchers in the Applied Mathematics Department, have made great progress: establishing the distribution and behaviour of the dark matter in a galaxy.

New mathematical calculations on the dark matter describe the density profiles which define how the dark matter changes in a galaxy. This had not been specified in the astronomy field yet. Until now, the behaviour of the dark matter had been estimated through simulations, but the new mathematical description approach based on equations and functions which describe each characteristic of the dark matter make this result much more reliable.

Socialism Vs Communism

Socialism is liberal. More people (preferably everyone) have some say in how the economy works. Democracy is liberal. More people (preferably everyone) have some say in how the government works. "Democracy," said Marx, "is the road to socialism." He was wrong about how economics and politics interact, but he did see their similar underpinnings.

Communism is conservative. Fewer and fewer people (preferably just the Party Secretary) have any say in how the economy works. Republicans are conservative. Fewer and fewer people (preferably just people controlling the Party figurehead) have any say in how the government works. The conservatives in the US are in the same position as the communists in the 30s, and for the same reason: Their revolutions failed spectacularly but they refuse to admit what went wrong.

A common mistake is to confuse Socialism, the economic system, with Communism, the political system. Communists are "socialist" in the same way that Republicans are "compassionate conservatives". That is, they give lip service to ideals they have no intention of practicing.

What is a Fractal ?

A fractal is generally "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,"[1] a property called self-similarity. Roots of mathematical interest on fractals can be traced back to the late 19th Century; however, the term "fractal" was coined by Benoît Mandelbrot in 1975 and was derived from the Latin fractus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion.

Shiva's Cosmic Dance at CERN

Nice one! On June 18, 2004, an unusual new landmark was unveiled at CERN, the European Center for Research in Particle Physics in Geneva — a 2m tall statue of the Indian deity Shiva Nataraja, the Lord of Dance. The statue, symbolizing Shiva's cosmic dance of creation and destruction, was given to CERN by the Indian government to celebrate the research center's long association with India.
