Sound Science Bite: March 26, 2012. Surprisingly, closure on the faster than light neutrinos has come quickly. A loose cable that could have caused a timing error was found by the OPERA team that reported the superfast neutrinos. That timing error could be responsible for making it appear the neutrinos were faster than light ("superluminal"). Another detector at the same laboratory as the OPERA experiment, called ICARUS, has timed neutrinos emitted from CERN and found they did not travel faster than light. It appears the case is closed (unless something else unexpected rears up).

Physics Book, an online physics textbook, work in progress. © Francis Redfern, 2001-10.

Physics Journal. © Francis Redfern 2010. This is a new (and exciting!!) feature (as of May 2010), featuring (as features usually do) a potpourri of physics stuff, ranging from tutorial type material to possibly original work (regarding which I am too lazy to bother with all the peer review wars and to verify whether or not it is really original). Check it out!

Virtual Geological Field Trips to Big Bend National Park, © Francis Redfern, 2006-10, another work in progress. (Are you up to the climb to Telephone Canyon? If so, come along and check out its geology!)
