Quantum mechanics is the most accurate (and strangest) theory in the history of physics. Yet it has great difficulty making accurate predictions for “many-body” systems — those involving a large number of particles. Physicists Nikolai Prokof’ev and Boris Svistunov at the University of Massachusetts Amherst with three alumni of their group propose a novel solution: [...]
Is “God” necessary for the creation of the universe? This is the central question in Lawrence Krauss’s popular science book, A Universe from Nothing. After a fascinating tour of modern cosmology — including the expansion of the universe, the hot big bang, matter and antimatter, cosmic inflation, dark matter and dark energy — Krauss reveals [...]
“Lord, take care of me now,” Joe silently prayed. USAF Captain and test pilot Joseph Kittinger had just ridden a gigantic helium balloon from the Earth’s surface to nearly 20 miles above the New Mexico desert floor. Then he jumped — out of his cramped gondola, literally into thin air. Kittinger’s Historic Leap “Try anything” [...]
Has science devised a better solar-power plant? Established in December of 2011, the Floating Tracking Cooling Concentrator (FTCC) is a new Photovoltaic (PV) plant system. In this system, the PV panels are placed on floating supports in water reservoirs. The FTCC makes the plant more efficient, and results in a smaller impact on the environment. [...]
How long are Pickering emulsions stable? A new study, published in Nature Materials in December 2011, investigated the time necessary for a Pickering emulsion to reach equilibrium conditions. The results showed that the process is much slower than expected, as the equilibrium timescale can be of the order of months. The slow kinetics of the [...]
