Three physicists from RIKEN have illustrated the ability of an ultrafast form of transmission electron microscopy to quantify sound waves in nanostructures. A cutaway of the ultrafast transmission ...

Extremely structured electromagnetic pulse carries not only the ultimate human dream of ultra-fast and ultra-intense energy extraction but also numerous extraordinary fundamental physical effects. As ...

To produce your thoughts and actions, your brain processes information in a hierarchy of regions along its surface, or cortex, ranging from "lower" areas that do basic parsing of incoming sensations ...

What Is A Periodic Wave? A periodic wave is a wave with a repeating continuous pattern which determines its wavelength and frequency. It is characterized by the amplitude, a period and a frequency.
