Physicists in Australia and Britain have reshaped quantum uncertainty to sidestep the restriction imposed by the famous Heisenberg uncertainty principle—a result that could underpin future ultra-precise sensor technology ...
The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843.
The neutral atom array architecture for quantum computing has been rapidly advancing over the last several years, and a recent study published in Nature has just revealed another step forward for this technology. The team ...
On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to reach us at the speed of ...
Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor electronic chips. But ...
A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King's College London reveal. The paper is published in the journal Physical Review X.
In the Cretaceous period, Earth was plagued by widespread volcanic activity, oceanic oxygen depletion events, and mass extinctions. Fossils from that era remain and continue to give scientists clues as to what the climate ...
American historian Josiah Ober, whose studies of Athenian democracy provide insights into current political crises, and U.S. immunologist Carl H. June, who works on gene-modified cell therapy that offers hope for future cures ...
Within our Milky Way galaxy, in the direction of the constellation Vulpecula, a cosmic "lighthouse" named PSR B1937+21 spins at an astonishing rate of 642 revolutions per second. It emits electromagnetic pulses that rival ...
Imagine a clock that doesn't have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, the same materials that ...
