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…

I just recently watched a video where they were explaining the double slit experiment. I understand that the interference pattern would be observed if you send photons or electrons one after the other. The conclusion that the author seems to make is that it is as though the particle/packet of energy travels through both the slits after somehow splitting into two. Has anyone done an experiment whe…

Artificial womb technology is approaching over the scientific horizon. Recent proof-of-principle experiments using foetal animals have prompted a new surge of bioethical interest in the topic: scholars have asked what ectogenesis would mean for individuals, family, oppressed groups, and society at large; how we can or should regulate the technology; and whose interests motivate ectogenic research…

An assistant can be honest, obedient and caring, yet become the only route through which a person finds evidence, frames alternatives and prepares disagreement. The right to correct survives; the capacity to form a correction narrows. Responding to Jakub Pachocki's call for AI that retains honesty, integrity and love for humanity across unfamiliar situations and optimization pressure, this essay …

Most of the self-hosting advice you'll find was written against 2024 assumptions. API pricing is expensive and linear, hardware is fixed and amortizes, so past some volume you break even. Buy the GPU, stop paying rent. Two things broke that this year, and they moved in opposite directions. Inference got cheaper OpenAI cut GPT-5.6 pricing twice over the summer, dropping Luna by 80% and Terra by 20…

The recent Landtag election in Sachsen-Anhalt has received widespread media attention beyond Germany's borders (AP, Reuters, Le Monde, SRF). The AfD received 43.8% of the vote, by far the largest ...

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

Quantum computers are supposed to have abilities far beyond conventional ones, but verifying that they...

Nature Reviews Drug Discovery, Published online: 07 September 2026; doi:10.1038/s41573-026-01514-3 There are currently no approved therapies for sarcopenia, the age-related loss of skeletal muscle mass and strength. This Review discusses advances in understanding of the cellular, molecular and metabolic mechanisms driving muscle wasting with ageing, while assessing emerging therapeutic approaches…

A new study in mice and patients shows that atherosclerosis meets the criteria for an autoimmune disease.
