Second Law of Thermodynamics May Explain Economic Evolution
Physicist Proposes Solution to Arrow-of-Time Paradox
Could Maxwell's Demon Exist in Nanoscale Systems?
Thought experiment proposed to reconcile psychological versus thermodynamic arrows of time
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
Physicist finds that E. coli replicate close to thermodynamic limits of efficiency
All living things must obey the laws of physics—including the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow. Highly ordered cells and organisms appear ...
Surfing on acoustic waves (w/ Video)
(Phys.org) —ETH researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control ...
Atoms at negative absolute temperature: The hottest systems in the world
(Phys.org)—In cold regions on earth, negative temperatures on the Fahrenheit or Celsius scale can often occur in winter; in physics, however, they were so far impossible. On the absolute temperature scale ...
New theoretical technique applied to properties of ultrathin solar cells
Rice's 'quantum critical' theory gets experimental boost
New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that ...
