this question is a modified version of my previous question:https:[//physics.stackexchange.com/q/875717/589276] Consider the coordinate system S'. In the S' frame, there is a uniform magnetic field of magnitude B' in the x'y'-plane. The magnetic field lines are perpendicular to the x'y'-plane and point outward from the plane. There is also a uniform electric field E' in the x'y'-plane, directed d…

Quantum theory says a vacuum isn’t truly empty, but proving it directly has remained out of reach. A new experiment using immensely powerful lasers could finally expose its hidden structure – and perhaps offer clues to dark matter

Insider Brief PRESS RELEASE — Matt Pines, Alex Klokus and Dr. Alexander Wissner-Gross has launched Physical Superintelligence(PSI), an AI-focused physics research lab developing computational models and tools for designing and optimizing physical systems. PSI also announced $58 million in seed funding led by Breakthrough Energy Ventures, with participation from Dragon Global, Robot Ventures, Sola…

A cooling cup of coffee seems to follow a simple rule: heat moves from warmer areas to cooler ones. This familiar process has been described successfully for about two centuries. But at the tiny scales found inside modern computer chips, heat can behave in much stranger ways. A new theoretical framework developed by Auburn University […] The post Heat Can “Remember” Its Past, New Theory Reveals a…

This technical treatise establishes the unified mathematical extension of the Primary Logical Infrastructure (PLI) framework (Sottosanti, 2026). By mapping the continuous spacetime manifold onto a discrete, graph-theoretical matrix (G_p), the analytical and physical breakdowns of orthodox continuous physics are systematically regularized. First, bridging the author's foundational work on syntacti…

Nuclear weapons have been banned from space for nearly 60 years. A new detection method could help verify whether nations are keeping that promise.

Fred James (1939 – 2026) — Fred James, CERN’s renowned expert on data analysis and statistics, pioneer of numerical methods, and co-author of the popular book Statistical Methods in Experimental Physics, sadly passed away on 31 July.  Fred was born in Detroit, USA, on 28 May 1939, and graduated in 1960 from Princeton University with a degree in physics.
