The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...
A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...
A decade-long effort to measure one of physics’ most fundamental constants culminates in a moment of uncertainty and ...
Google's latest Doodle highlights quantum physics, showcasing the Bloch sphere and qubits. This celebrates World Quantum Day, ...
A researcher at the Department of Physics at Tohoku University has uncovered a surprising quantum phenomenon hidden inside ordinary crystals: the strength of interactions between electrons and lattice ...

From cubits to constants, the story of measurement
From pacing out distances with our feet to defining the kilogram by the Planck constant, measurement has come a long way. Across history, humans have sought consistent ways to compare, quantify, and ...
Images made with the W.M. Keck Observatory in Hawaii show how light from two distant galaxies is distorted into multiple images. UC Davis astronomers have made a new estimate of the Hubble Constant, ...
Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...
