LEE SMOLIN 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. iFixit: The free repair manual. 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. To handle the interest generated by the LHC, CERN has built a new visitor's center to introduce the public to the work that goes on there.

For this visit, however, the tour started across the street, next to the CERN gift shop (yes, it has a gift shop). Other hardware doesn't quite get this honorable treatment. Inside, however, the hardware was cutting edge. Retraction Watch. ScienceBlogs.

Study Hacks. The Opposite of the Open Office October 19th, 2016 · 12 comments The Bionic Office A couple weeks ago, I wrote about Joel Spolsky’s claim that Facebook’s massive open office is scaring away talent.

The comments on the post added many interesting follow ups; e.g., a pointer to a recent podcast episode where a Facebook developer claims the office is rarely more than a third full as people have learned to stay home if they want to produce anything deep.

Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it!

Spectrum: A Robot That Balances on a Ball

Masaaki Kumagai, director of the Robot Development Engineering Laboratory at Tohoku Gakuin University, in Tagajo City, Japan, has built wheeled robots, crawling robots, quadruped robots, biped robots, and biped robots on roller skates. Then one day a student suggested they build a robot that would balance on a ball. Dr. Kumagai thought it was a wonderful idea. The robot they built rides on a rubber-coated bowling ball, which is driven by three omnidirectional wheels.
