Vortex (OAM) particle beams might complement or replace spin-polarized beams in accelerators. Timescale for OAM loss by photon emission significantly exceeds typical acceleration times and radiative OAM dynamics is governed by precession at a frequencies distinct from those of spin. Linacs could accelerate vortex beams, and Siberian snakes adapted for OAM control journals.aps.org/prl/pdf/10.…

Happy to announce I built a Greek/English reader site with all the surviving plays of Aeschylus, Sophocles, Euripides, & Aristophanes. Multiple translations for each play; click to parse & define for any Greek word; full Greek & English search. greekdrama.johnhboyer.com

The Greek Drama Reader — Greek tragedy and comedy, Greek and English side by side

Read the Greek plays in the original Greek with a facing English translation, side by side — with click-to-parse morphology, dictionary lookup, citation, and full-text search across the corpus.

A Quantum Cyclotron for Antimatter

A device that stores a single positron and controls its quantum states could measure its magnetic moment with unprecedented precision, testing a symmetry principle central to quantum field theory.

Projected AI data-center buildout: $10.3 trillion by 2032—larger than railroads, highways, or the internet boom. Needs $3.7T/year in revenue by 2032 just for a 10% return. Funded increasingly with hidden debt. Biggest single-industry bet in U.S. history papers.ssrn.com/sol3/papers.…
