honor of that achievement, Physics Today put together an interactive crossword puzzle with a LIGO theme. Give it a try at the link below.
research, including the cryoelectron microscopy work that won the chemistry Nobel.
concerned not only about plane trigonometry but also spherical, so that astronomers could adequately describe the motion of the stars on the celestial sphere. Here's a primer on this trigonometry for the heavens.
researchers announced that the program had defeated the best computer players of the games chess and shogi. The AI mastered each game in a matter of hours by playing itself many times, having started out with only the basic rules.
measurements led to a conclusion that no one had predicted: the existence of belts of energetic particles, now called the Van Allen belts, that are trapped by the planet's magnetic field. Space physicists Daniel Baker and Mikhail Panasyuk tell the story of the belts' discovery 60 years ago and the puzzling features that scientists are still sorting out.
has written dozens of astronomy books, also shared tips for people interested in science communication.
these materials achieve superconductivity at temperatures as high as 134 K (at normal pressure) is still a mystery. Now a new study shows that cuprates seem to host vortex states that are typical of conventional superconductors described by the Bardeen-Cooper-Schrieffer, or BCS, theory. That's a surprise, since physicists have thought that cuprates operate via a different mechanism.
