We are sharing two candidate magnets for next-generation computer memory, found by a team of Claude Opus 5.5 agents. Both are predicted to have zero net magnetism yet still sort electrons by spin: one a new compound we designed, the other a material first made in 1999. We're…
Here are the best books to become an expert in Quantum Mechanics, with no experience needed.

The Large Hadron Collider has stopped colliding. It will be four years before it starts again.
Collider in China forges elusive particle, made of force-carrying gluons
Note: Matter is like a Russian doll. Molecules are made of atoms, atoms of electrons and nuclei, and nuclei of protons and neutrons. Protons and neutrons, in turn, consist of quarks held together by a swarm of gluons. A glueball would be different: a particle whose mass comes almost entirely from gluons bound to one another, with little or no quark content.
After 15 years of research, scientists discover definitive evidence of glueballs using the Beijing Electron Positron Collider II.
