A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

Light is closely integrated with our intellectual, philosophical and scientific discourse. The exact nature of light has remained a mystery since we stepped on earth. Newton postulated the corpuscular ...

The energy of light is associated with its intensity and is proportional to the square of the amplitude of the electric field ... of an electron of charge e in the field of time varying magnetic ...

Envelope equations for a continuous beam with uniform charge density and elliptical cross-section were first derived by Kapchinsky and Vladimirsky (K-V). In fact, the K-V equations are not restricted ...

The ES90 also features brand-new, in-house-developed battery management software that creates a more robust charging experience. Compared to other electric Volvo cars, this new software reduces ...
