Much has been made of the excessive power demands of AI, but solutions are sparse. This has led engineers to consider ...

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 ...

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 ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...

(Nanowerk News) Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

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 ...

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 ...

(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 ...
