This is a continuation of "As is well known about elliptic trajectories" where I have put it as a sort of homework to find out which force fields support elliptic trajectories. The "problem" has…

Chinese researchers have created a hypothesis for a quantum cloning machine able to produce several copies of the state of a particle at atomic or sub-atomic scale, or quantum state, which if…

The Arxiv today features a quick-and-dirty study of the occurrence of electron-positron pair signal in the NOMAD detector, which obtains very strong bounds on the superluminal behaviour of energetic…

Scientists in Australia are claiming that the laws of physics might be like local by laws which vary from one location to the next and that if this is true then Einstein’s relativity may also be…

In a recent study, scientists used simulations to model the behavior of a closed, granular system comprising a chain of equal-sized spheres that touch one another and are sandwiched between two walls…

From time to time and against strong resistance from the scientific establishment, inspired scientists come out of the closet and dare to publicly consider whether the future can influence the…

The following is an excerpt from a book I am working on intermittently. I do not know whether the project will ever see the light, and it just occurred to me that I could share a tiny bit of it with…

RETRACTION: I have decided to retract three blogs (Deriving … 4/5, 5/5, 6/5+1). I was unable to figure out a reasonable statement concerning gauge symmetry. When the blogs were initially written, I…

Europe is moving forward at high speed to build ELI (Extreme Light Infrastructure Ultra-High Field Facility), to be completed by the end of the century. The location for the facility will be…

There is a certain amount of confusion on the relationship between Einstein's Theory of Relativity and the recent experimental results that seem to point towards neutrinos that are faster than light…
