Why even physicists still don’t understand quantum theory 100 years on by rntn

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television set when the picture went fuzzy. Today, it might be turning your computer off and on again. Quantum mechanics

Physicists get a first glimpse of the elusive isotope nitrogen-9 by sohkamyung

Researchers may have just spotted the elusive, ephemeral nucleus of nitrogen-9 for the first time. With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of what can even be considered a nucleus at all. Yet signs of its existence seem to be lurking in years-old data from experiments seeking

Physicists confirm 67-year-old prediction of massless neutral composite particle by geox

In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a “demon.” Since then

Quantum Physicists ‘Flipped Time’ (and How They Didn’t) by theafh

Physicists have coaxed particles of light into undergoing opposite transformations simultaneously, like a human turning into a werewolf as the werewolf turns into a human. In carefully engineered circuits, the photons act as if time were flowing in a quantum combination of forward and backward. “For the first time ever, we kind of have a

Physicists find that organelles grow in random bursts by rolph

Research from Washington University in St. Louis suggests that organelles in the eukaryotic cell grow in random bursts from a limiting pool of building blocks. Credit: Shutterstock Eukaryotic cells—the ones that make up most life as we know it, including all animals, plants and fungi—are highly structured objects. These cells assemble and maintain their own

Physicists Simulate a Simplified Wormhole on Google’s Quantum Computer by cheinyeanlim

Wormholes might sound like something that belongs in a Star Trek episode rather than a research paper, but scientists just simulated one on Google’s Sycamore quantum computer. The result suggests these devices could be used to test out fundamental physical theories. The possibility of wormholes was first outlined in a 1935 paper by Albert Einstein…

Physicists Create a Wormhole Using a Quantum Computer by georgehill

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information, even as the work’s interpretation remains disputed. IntroductionPhysicists have purportedly created the first-ever wormhole, a kind of tunnel theorized in 1935 by Albert Einstein and Nathan Rosen that leads from one place to another by passing into an extra dimension of space.…

Physicists Pin Down How Quantum Uncertainty Sharpens Measurements by pseudolus

quantum physicsBy Ben BrubakerMay 3, 2022Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.Quantum fuzziness can sometimes aid measurement rather than hinder it.Quanta MagazineScientific progress has been inseparable from better measurements. Before 1927, only human ingenuity seemed to limit how precisely…

Physicists elucidate connection between symmetry and Mott physics by rbanffy

Credit: CC0 Public Domain Initially regarded as a scientific curiosity upon its discovery in 1911 by Heike Kamerlingh Onnes, superconductivity has provided physicists with numerous theoretical challenges and experimental surprises. From the development of Bardeen-Cooper-Schrieffer (BCS) theory at the University of Illinois Urbana-Champaign in 1957 to the discovery of high-temperature superconducting cuprate ceramics in 1987,…
