Hints of New Physics Crop Up at LHC
Preliminary findings from CERN’s Large Hadron Collider may have uncovered experimental evidence for physics beyond the Standard Model. Data from the CMS experiment is showing significant excesses of particles known as leptons being created in triplets, a result that could be interpreted as evidence for a theory called supersymmetry.
The findings, presented during a talk Oct. 19 at a conference dedicated to LHC searches for new physics, have piqued the interest of some members of the field.
“This is clearly something to watch closely over the coming months,” physicist Matt Strassler wrote on his blog. That’s because these particular triple lepton signatures are sometimes called the “golden channel” to revealing supersymmetry, a theoretical model that posits the existence of a heavier partner to all known subatomic particles in order to solve certain problems with the Standard Model.

Link The Secret Lives of Photons

3DPhoton

Is the Heisenberg uncertainty principle under attack?  An international team of researchers claims to have mapped complete trajectories of single photons in Young’s double slit experiment.

Physicist Aephraim Steinberg of the University of Toronto and his team say they have used a technique called “weak measurement” to accurately measure both position and momentum of single photons in a two-slit interferometer experiment.  If true the results would seem to violate Heisenberg’s uncertainty principle which declares that nature limits the amount of information that can be measured from complimentary variables of a quantum system.  It could also undermine the foundation of the Copenhagen interpretation of Quantum Mechanics.

The research is published in the journal Science.

Multiple pendulums of varying length and thus frequency are set off at the same time. This creates an awesome pattern which phases in and out of order, at times looking chaotic, and eventually comes back to roughly where it started.

Link Martin Rees wins £1m Templeton Prize

Martin Rees

One of the most amazing experiences I ever had was listening to cosmologist Martin Rees speak at Stanford in 2002 on the multi-verse theory.  In a talk that lasted less than an hour he transformed the way I view classical physics, and the relationship between science and religion.  Although the linked article identifies Lord Rees as an athiest, one comes away from his presentation with profoundly religious thoughts.  I will never forget the short time I was able to spend in his presence.  There is no scientist alive today who I hold in higher regard.
