Why Is Glass Rigid? Signs of Its Secret Structure Emerge.
At the molecular level, glass looks like a liquid. But an artificial neural network has picked up on hidden structure in its molecules that may explain why glass is rigid like a solid.
The Cartoon Picture of Magnets That Has Transformed Science
One hundred years after it was proposed, the Ising model is used to understand everything from magnets to brains.
‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles
Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.
To Make the Perfect Mirror, Physicists Confront the Mystery of Glass
Sometimes a mirror that reflects 99.9999% of light isn’t good enough.
Ideal Glass Would Explain Why Glass Exists at All
Glass is anything that’s rigid like a crystal, yet made of disordered molecules like a liquid. To understand why it exists, researchers are attempting to create the perfect, still-hypothetical “ideal glass.”
The Man Making Rwanda Into a Hub for Physics
As the founding director of a new institute for fundamental research in Rwanda, the physicist Omololu Akin-Ojo hopes to stem the brain drain of Africa’s brightest minds.
Toward a Grand Unified Theory of Snowflakes
Snow crystals come in two main types. The “pope” of snowflake physics has a new theory that explains why.
Strange Metal-like Bonds Discovered in Customized Crystals
While studying materials made from DNA-coated nanoparticles, researchers found a new form of this matter: lattices in which smaller particles roam like electrons in metallic bonds.
What’s the Magic Behind Graphene’s ‘Magic’ Angle?
A new theoretical model may help explain the shocking onset of superconductivity in stacked, twisted carbon sheets.
