All of us know the effects of the mysterious force called gravity. However, the question 'what is gravity' is not easy to answer at all. The reason is that we don't really understand what this force actually is (if it is a force at all). This non-technical article answers the question up to the current well-proven classical understanding of the physics behind gravity. It deals with the evolution of classical gravity theory by Kepler, Newton and Einstein, but stops short of the current developments in quantum gravity. |

It was the ultimate corporate nightmare . A high-profile flagship project – a flagship not merely for the company, but a flagship high-technology programme for an entire continent – went embarrassingly, expensively, and very publicly wrong. And it was a simple industrial-isation issue, a production ramp-up problem, and something that should never have happened. |

Zimbabwe's gold producers are operating below 20% of capacity while some have suspended operations over a deepening economic crisis and electricity cuts, the mining chamber said on Friday.
The news came after President Robert Mugabe on Wednesday threatened to seize and nationalise mines, especially gold producers he accused of smuggling the metal outside the country and stashing foreign currency earnings abroad as part of a campaign to undermine his government. |

In February of this year the European Commission proposed to force automotive manufacturers to cut carbon dioxide (CO2) emissions from cars by 18percent, with new cars expected to meet this target by 2012. In addition, stricter standards have been proposed so that between 2011 and 2020 fuel suppliers in the EU will have to achieve a 10percent reduction in the greenhouse gas emissions their fuels produce when they are refined, transported and used. Improvements in fuel quality will cut emissions even further. |
