The ordinary weirdness of quantum mechanics

The spook and the weirdness, they stand in for non-locality and contextuality, they replace correlations and entanglement, pure and mixed states, non-commutativity, error correction, path integrals or post-selection. Unfortunately, all too often the technical vocabulary is entirely absent rather than briefly introduced. This makes it very difficult for interested readers to dig deeper into the topic. (Credit: C.

Mixing in star-forming clouds explains why sibling stars look alike

This is an image from a computer simulation shows a collision of two streams of interstellar gas, leading to gravitational collapse of the gas and the formation of a star cluster at the center. In this image, the gas streams were labeled with blue and red "tracer dyes," and the purple color indicates thorough mixing of the two gas streams during the collapse. Credit: Y. Feng and M. Krumholz

The power of hidden patterns

Interfaces between solid materials are surfaces with intricate, internal structure (shown on the left). To control that structure, and to use it for specific applications, researchers model it a simplified way (shown on the right). Image: Niaz Abdolrahim and Jose-Luis Olivares/MIT

Asteroid 1950 DA’s Encounter with Earth in 2880(PDF)

(29075) 1950 DA is a near-Earth asteroid. Among asteroids more than 1 km in diameter, it is notable for having the highest known probability of impacting Earth.

Krauss, Wilczek honored with first prize from Gravity Research Foundation

The Krauss-Wilczek paper describes how the recent claimed discovery of gravitational waves from the early universe can provide definitive evidence that gravity must be understood as a quantum theory.
