Kidnapster comments on master ruseman /u/jeinga starts buttery flamewar with /u/crotchpoozie after he says he's "smarter than [every famous physicist that ever supported string theory]"; /u/jeinga then fails to answer basic undergrad question, but claims. Waffle299 comments on Ultra-rare decay confirmed in LHC "Scientists have confirmed one of the rarest phenomena of decay in particle physics, found about three times in every billion collisions at the LHCb. They observed a particle called a Bs meson decayi. Time Reborn: From the Crisis in Physics to the Future of the Universe (9780547511726): Lee Smolin, Henry Reich. Contents. So You want To Become a Physicist? 19 November 2012 - BaBar Experiment Confirms Time Asymmetry. Interactions NewsWire #91-12 19 November 2012 ******************************************* Source: SLAC National Accelerator Laboratory Content: Press Release Date Issued: 19 November 2012 ******************************************* Time's quantum arrow has a preferred direction, new analysis shows Menlo Park, Calif. — Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss.
But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time reversal symmetry. Now the BaBar experiment at the Department of Energy's (DOE) SLAC National Accelerator Laboratory has made the first direct observation of a long-theorized exception to this rule. BaBar's new time violation analysis was based on a concept proposed in 1999. Media Contact: Related Links: J. I Love Charts. Higgs Papers Out. We were all transfixed by the Higgs seminars on July 4, but the work was nowhere near over for the experimentalists — they had to actually write up papers describing the results.
And of course taking the opportunity to do a little more analysis along the way. Now the papers have appeared on the arxiv. (Via lots of places, e.g. symmetry breaking and Matt Strassler.) Here’s ATLAS: Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHCThe ATLAS Collaboration (Submitted on 31 Jul 2012)A search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC is presented. And here’s CMS: No huge surprises, I would say, but a few tiny tweaks to the earlier announcements.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures.
At the same time, my lecture notes have evolved. This text owes a lot to many.
