Conservation laws, consisting of the existence of quantities which do not change in time, independent of the dynamical evolution of a system, are crucial and...

The answer could be yes, because of a small detail that has been overlooked for decades and that was not known in 1905. Applying the...

The covariant derivative of the 4-components electromagnetic potential in a flat Minkowski spacetime is split into its antisymmetric and symmetric parts. While the former is...

Cell biology has entered the age of quantum biology. In some situations even a single electron matters, particularly with respect to the mind-body dialogue. More...

We apply the perturbative technique which was previously developed in cosmology to now describe the gravitational field of a galaxy with arbitrary rotation curve. We...

This communication presents a simulation of the stability characteristics of nonlinear surface waves propagating along a left-handed substrate (LHM) and a non-linear dielectric cover. The...

What is "electronic charge"? Why there are two kinds of charges? Why do the same charges repel, and dissimilar charges attract each other? Why does...

Analyzes the Big Bang theory, recession of galaxies, Hubble's law, multi-dimensional space, curved space and a black hole in modern cosmology and points out that...

What is the nature of light? Particle or wave? How fast is the speed of light? These are all basic questions of physics. From points...

Selection of the coordinate system is essential for rotation problems. Otherwise, mistakes may occur due to inaccurate measurement of angular speed. Approximate inertial coordinate system...
