A deep dive into the Amplituhedron, introduced in 2013 by Nima Arkani-Hamed and Jaroslav Trnka, as a geometric reformulation of scattering amplitudes in planar N=4 supersymmetric Yang–Mills theory. In momentum-twistor space, a positive geometry encodes interaction probabilities as a volume (more precisely, a canonical volume form), bypassing thousands of Feynman diagrams and virtual particles. We’ll unpack how locality and unitarity emerge from geometry, why this approach massively simplifies...

A concise tour of Wilhelm Röntgen’s 1895 discovery of X‑rays, the physics of high-energy photons, and how these invisible rays became one of medicine’s most powerful tools. We cover how X-ray imaging works—from shadowy radiographs to CT and real-time fluoroscopy—why contrast depends on atomic number, and other key applications in industry and science. We also discuss the ionizing hazards, safety measures, and the balancing act between enormous benefits and biological risk. A curious note on t...

In early February 2025, something strange started happening across US government websites. Decades of data began disappearing from webpages for agencies such as the Centres for Disease Control and Prevention, the National Institutes of Health and the Census Bureau. In many cases the entire website went dark. Within a few days some 8,000 government pages and 3,000 datasets had been taken down. Since then, many have been reinstated - but some have not. We speak to Professors Maggie Levinstein and
