To understand the path forward, it helps to revisit the physics that underpin our understanding of energy. Einstein’s e=mc^2 ...

The electromagnetic linear momentum and the energy balance in an infinite solenoid with a time-dependant ... electromotive force (which is the negative of Equation (19)) is exactly equal to the stored ...

Abstract: Using long-duration general relativistic magnetohydrodynamic simulations of radiatively inefficient accretion discs, the energy, momentum and mass outflow rates from such systems are ...

Three idealized problems are analysed. The modulation equations comprise conservation of waves, averaged conditions for conservation of mass, momentum, kinetic energy and angular momentum and the ...
