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. Massachusetts, The people of Massachusetts have always stood up for their right to repair.
In 2012, voters passed a law that ensured residents' right to repair their car wherever they wanted. Now, it's time to do the same for electronics. With the Digital Right to Repair Bill, H.3383, we have a chance to guarantee our right to repair electronics — like smartphones, computers, and even farm equipment. We have a chance to help the environment and stand up for local repair jobs—the corner mom-and-pop repair shops that keep getting squeezed out by manufacturers. The Digital Right to Repair Bill requires manufacturers to provide owners and independent repair businesses with fair access to service information, security updates, and replacement parts. 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). Retraction Watch. ScienceBlogs. ScienceBlogs.com.br. Gene Repórter. ESTE OU AQUELE? Pharyngula.

The Collatz conjecture is a conjecture in mathematics named after Lothar Collatz, who first proposed it in 1937.
The conjecture is also known as the 3n + 1 conjecture, the Ulam conjecture (after Stanisław Ulam), Kakutani's problem (after Shizuo Kakutani), the Thwaites conjecture (after Sir Bryan Thwaites), Hasse's algorithm (after Helmut Hasse), or the Syracuse problem; the sequence of numbers involved is referred to as the hailstone sequence or hailstone numbers (because the values are usually subject to multiple descents and ascents like hailstones in a cloud), or as wondrous numbers.

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. Www.whonamedit.com.
