At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first ...

Much has been made of the excessive power demands of AI, but solutions are sparse. This has led engineers to consider completely new paradigms in computing: optical, thermodynamic, reversible—the list ...

Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing the ...

There is no sound in space, at least not the kind of sound we as humans can detect. There is, however, something akin to sound if you have the right tools to listen to it. Share on Facebook (opens in ...

Four years ago the first modern electron microscope was exhibited by the Siemens & Halske A.-G., in Berlin (TIME, June 6, 1938). Two years ago the R.C.A. Laboratories completed the first commercial ...

(Nanowerk News) One of the most fundamental interactions in physics is that of electrons and light. In an experiment at Goethe University Frankfurt, scientists have now managed to observe what is ...

FRANKFURT. It was one of the biggest surprises in the history of science: In the early days of quantum physics around 100 years ago, scholars discovered that the particles which make up our matter ...
