Weyl points: Long-sought phenomenon finally detected
Part of a 1929 prediction by physicist Hermann Weyl—of a kind of massless particle that features a singular point in its energy spectrum called the "Weyl point,"—has finally been confirmed by direct observation for the ...

New kirigami-inspired models predict how new metamaterials behave
A traditional paper crane is a feat of artistry. Every fold in origami leads to the transformation of a single square sheet of paper into a bird, a dragon, or a flower. Origami discourages gluing, marking or cutting the paper, ...

Zoom-up star photos poke holes in century-old astronomical theory
(PhysOrg.com) -- The hottest stars in the universe spin so fast that they get a bit squished at their poles and dimmer around their middle. The 90-year-old theory that predicts the extent of this "gravity darkening" phenomenon ...

Mathematicians ask: What's in a ripple?
When a fluid or a gas experiences a sudden disturbance, such as a change in pressure or elevation, it often gives rise to a phenomenon known as an undular bore, which consists of a series of rapid oscillations that propagate ...
