A new study posits that this muon might be the result of a dark matter particle that decayed as it passed through the Earth, which would also explain why the IceCube Observatory in the South Pole ...

In this woodworking video, I use a woodturning lathe to turn some coloured card into a decorative art piece. The sound of chisels shaping wood, the smooth finish, and the spinning lathe ...

A new variant of particle swarm optimization (PSO), named phase angle-encoded and quantum-behaved particle swarm optimization (θ-QPSO), is proposed. Six versions of θ-QPSO using different mappings are ...

Space 'Impossible' particle that hit Earth may have been dark matter We may already have had our first-ever encounter with dark matter, according to researchers who say a mysteriously high-energy ...

The particle swarm is an algorithm for finding optimal regions of complex search spaces through the interaction of individuals in a population of particles. This paper analyzes a particle's trajectory ...
