Big Bang Fears
The world's biggest physics experiment will suffer another setback in two years time when it is expected to be shut down for repairs, pushing full operating capacity back another year.
The world's biggest physics experiment will suffer another setback in two years time when it is expected to be shut down for repairs, pushing full operating capacity back another year. "Scientists in charge of the Large Hadron Collider (LHC) in Geneva announced yesterday that the machine will only be able to run on half energy before it is temporarily shut down in two years' time. Its full operating capacity designed to probe the frontiers of science will not be achieved until at least 2013 – several years later than planned. However, the European Centre for Nuclear Research (Cern), which operates the £2.6bn atom-smasher on the Franco-Swiss border, said that the additional costs of correcting the problem in the machine's copper sheaths or "stabilisers" would come out of its existing budget and it would not be asking for any additional funding from contributing countries, including Britain. On 19 September 2008, the LHC had to be shut down just days after it was switched on for the first time because of an electrical fault that led to helium gas being accidentally released into the machine's underground tunnel. The fault took £25m to fix but Cern's engineers found that further work on the copper stabilisers designed to soak up spare electrical current from the supercooled magnets was needed before the machine could go to full energy. 'I wouldn't call it a design flaw. It is just that some of the copper stabilisers are not up to the quality needed to go to the full energy level,' said Steve Myers, director of accelerators and technology at Cern."
The ability to speak clearly, succinctly, and powerfully is easier than you think
The ability to communicate effectively can make or break a person's assessment of your intelligence, competence, and authenticity.
The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
