Hands On Science - Journal
Founding and Senior Faculty member at Perimeter Institute for Theoretical Physics in Waterloo, Canada; Adjunct Professor of Physics at the University of Waterloo; Author, The Trouble With Physics Perhaps the most embarrassing example from 20th Century physics of a false but widely held belief was the claim that von Neumann had proved in his 1930 text book on the mathematical foundations of quantum mechanics that hidden variables theories are impossible. These would be theories that give a complete description of individual systems rather than the statistical view of ensembles described by quantum mechanics.

A photo tour of the Large Hadron Collider
Back in July, we were fortunate enough to have the opportunity to tour CERN, home of the Large Hadron Collider. In addition to getting some great information on how the machine gets protons up to speeds nearly that of light, and finding out the sorts of physics that scientists hope to find in its collisions, we also got a great view of some of the control rooms and hardware that help keep everything humming along. Unfortunately, with the LHC active, it wasn't possible to actually go down and see the massive detectors that capture the output of the proton collisions, but there's still a lot to see around CERN.Retraction Watch
We’ve been watching with interest an unfolding flap about a controversial 2003 paper in the Archives of Sexual Behavior ( ASB ) by a prominent mental health researcher, Robert Spitzer , which suggested that gays could be deprogrammed by so-called “reparative therapy” to change their sexual orientation.
By gluing radio chips to the backs of 800 honeybees, researchers proved that Neonicotinoid pesticides interfere with their behavior.

Vertebrates are modified segmented worms; that is, their body plan is made up of sequentially repeated units, most apparent in skeletal structures like the vertebrae. Arthropods are also modified segmented worms.
