We calculate the average speed of a projectile in the absence of air resistance, a quantity that is missing from the treatment of the problem in the literature.
We well know that photon concept is self-contradictory because we assume that it is a particle with wave properties. This contradiction insensibly spoils our su
A much simpler and self-consistent derivation of the non-linear component Gu×Gv of the quantum chromodynamic SU(3) field tensor is given which does not req
In this paper nonconservative systems are investigated within the framework of Euler Lagrange equations. The solutions of these equations are used to find the p
We study classical and quantum dynamics of the symmetric harmonic oscillator and the symmetric bouncer defined in 2-D. For these systems we get each of them for
The purpose of the present work is to derive some solutions for several solid angle cases via a fundamental formula which gives the solid angle for an isosceles
