New theoretical framework sets limits for the realization of quantum processes in spacetime
Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These are principles rooted in Einstein's theory of relati.....»»
Future iPhones getting even more memory: 12GB from next year
This year’s entire iPhone 16 line-up got 8GB RAM to run Apple Intelligence features, and it looks like we can expect 12GB in future models. A previous report suggested that iPhone 17 Pro Max would get 12GB, and it now appears that this may be tr.....»»
In a fusion device plasma, a steep ion temperature gradient slows the growth of magnetic islands
Future fusion power plants will require good plasma confinement to sustain reactions and generate energy. One way to contain plasma for fusion reactions is to use a tokamak, a device that applies magnetic fields to "bottle" plasma. However, magnetic.....»»
