The second law of thermodynamics delineates an asymmetry in how physical systems evolve over time, known as the arrow of time. In macroscopic systems, this asymmetry has a clear direction (e.g., one can easily notice if ...
(Phys.org) —The size of an object can be measured in many ways, such as by its mass, volume, or even the number of atoms it contains. And when it comes to quantum physics, "macroscopic" objects are considered to be larger ...
(PhysOrg.com) -- University of Warwick physicist has produced a galaxy sized solution which explains one of the outstanding puzzles of particle physics, while leaving the door open to the related conundrum of why different ...
