Book cover for Archives of Science In the new open-access volume Archives of Science: Challenges and Opportunities in the 21st Century, editors Polina Ilieva and Venkat Srinivasan bring together archivists and scholars from around the world to confront a central …

The team’s ultra-precise measurement confirms the Standard Model’s predictions. When fundamental particles are heavier or lighter than expected, physicists’ understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists’ …

📖Read Time: 5 minutes 📊Readability: Moderate (Standard complexity) 🔖Core Topics: om, mn, os, op, velocity The “Addition of Velocities” formula (more correctly, the “Composition of Velocities” formula) in Special Relativity [tex]\frac{v_{AC}}{c}=\frac{ \frac{v_{AB}}{c}+\frac{v_{BC}}{c} }{1 + \frac{v_{AB}}{c} \frac{v_{BC}}{c}}[/tex] is a non-intuitive result …

When I was pursuing a PhD at Caltech, so was my friend Jeremy. He used to throw a dinner party every few months. The email invitations welcomed friends to partake of his cooking and, if we wished, to help him …

Progress in quantum computing as an industry has been relatively stagnant for a while now. But over the past few weeks, that’s changed. Multiple groups focused on quantum cryptography (using quantum computers to break previously-unbreakable encryption protocols) published breakthrough papers …

A toad swims across a pond in this award-winning image from photographer Paul Hobson. The shot was actually captured from below the water, with the camera kept dry in a glass housing. Although the frog appears to be mid-leap, the …

In the last posting I explained how a fundamental problem shows up if you try to Wick rotate a Weyl spinor. Wick rotation is supposed to be analytic continuation in a four dimensional complex spacetime which, in terms of spinors, …

On March 20, 2026, Dr. Elise Crull gave the AIP Lyne Starling Trimble lecture “Hertha Sponer and the Path from Electron Diffraction to Wave/Particle Duality,” which focused on the contributions of physicist Hertha Sponer to early quantum experimentation. The recording …

MIT physicists have discovered 3D “moiré crystals” that simulate four-dimensional quantum materials to a T. The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make …
