Visitors to Saint Paul’s in London are often astonished by the cathedral’s whispering gallery, where words spoken in a whisper along the curving wall of the dome can be heard anywhere along that same ...

A few years later, the engineers Ernst Ruska and Max Knoll built the first electron microscope, which was more powerful than any light microscope. Given that electron waves are diffracted by much ...

Charges are accelerated away from each other by the fluctuating electric field from a terahertz laser. (Courtesy: Brian Long) Researchers at the University of California at Santa Barbara in the US ...

(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 ...

Photoelectrons excited by extreme ultraviolet or x-ray photons in the presence of a strong laser field generally suffer a spread of their energies due to the absorption and emission of laser photons.

(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 ...

Electronics traditionally rely on harnessing the electron's charge, but researchers are now exploring the possibility of ...

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 ...
