The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

The unit builds on A-level Physics A2 and some aspects of Core Physics A - Fields, Oscillations and Waves and associated tutorials - to introduce new concepts and put those already taught on to a firm ...

Figure 1: Graphene-clad silicon photonic crystal nanostructures. Figure 4: Parametric four-wave mixing in graphene-clad silicon nanocavities. We have demonstrated, for the first time, a hybrid ...

The quasi-biennial oscillation (QBO) is a nearly periodic reversal in the equatorial stratospheric zonal winds, characterised by alternating easterly and westerly regimes over an average period of ...

Waves of synchronized, coordinated neuronal activity have been observed and studied in the brain for over a century. But for ...

Using light pulses, scientists have recently managed to control theta oscillations in mouse brain. They discovered that these brain waves coordinate movement - enabling signaling between distant brain ...

An international group of astronomers led by a Harvard Ph.D. student reported their discovery that the Radcliffe Wave — a 9,000 light-year-long gaseous structure in the Milky Way — moves in an ...

Remember a few weeks ago when the tropics were quiet in the Atlantic, yet we had three to four tropical systems in the Pacific, and now that trend has seemingly flipped? There's a reason for that.

Alpha and gamma brain waves, which are visualized by means of electroencephalography (EEG) measurements, can provide doctors with information about a patient’s mental state for diagnostic purposes.

A new article suggests that 'unpredictable climate variability' behaves in a more predictable way than previously assumed. The scientists point to the so-called 'stadium-wave' signal that propagates ...
