Posthumous ArXiv Posting [The Quantum Pontiff] Thursday, March 11, 2010 @ 5:52PMHm, today we seem to have a posting from beyond the grave, arXiv:1003.2133 : Proof of the Ergodic Theorem and the H-Theorem in Quantum Mechanics Authors: John von Neumann Abstract: It is shown how to resolve the apparent contradiction between the macroscopic approach of phase space and the validity of the uncertainty relations. The main notions of statistical mechanics are re-interpreted in a ...
New charging method could greatly reduce battery recharge time Thursday, March 11, 2010 @ 5:33PM(PhysOrg.com) -- Part of the headache of having to constantly recharge batteries is not just how often they need to be charged, but also the time it takes to charge them. In a new study, researchers have proposed a charging method that could greatly reduce the charging time of lithium-ion batteries, which are used in everything from electronic devices to electric vehicles. The new method uses an ...

'We don't know what 96% of the universe is made of' Monday, March 8, 2010 @ 10:52AMPop star-turned-physicist Brian Cox speaks about his new TV series on the solar system It's big space, isn't it? It's 93 million miles to the Sun: that's a long way . It takes light eight minutes to do that. There are 100bn galaxies in the observable universe. If you take a 5p coin and hold it 75 feet away, the space in the sky it would obscure would hold 10,000 galaxies. It's mindblowing. I don ...

Photons led astray: Investigating the random motion of quantum particles Tuesday, February 23, 2010 @ 9:46AM(PhysOrg.com) -- Life would sometimes be so much easier if we were quantum particles. For example, if we were trying to find our way out of a strange town allowing chance telling us which way to go at every intersection. As objects of classical physics, this would mean becoming more and more lost in the centre of the road network. If we were particles that obeyed the laws of quantum mechanics ...
