kinetics of a particle: impulse and momentum
... • For application, a careful study of the free-body diagram for the entire system of particles should be made to identify the forces which create external impulses and thereby determine in which direction linear momentum is conserved. – If the time period over which the motion is studied is very sho ...

Nature of Inertia forces
... It is shown in [6,17] that to explain the weak interactions it is not necessary to introduce the Pauli’s hypothesis on existence of neutrino. The laws of conservation are taken over by the physical space structure formed from the object 4b. Now, when we can calculate periods of byuon interaction, x0 ...

... The main effort of science is to describe what happens in nature, in as complete and concise a form as possible. In physics this effort involves observing natural phenomena, relating these observations to previously established theory, and finally establishing a physical model for the observations. ...

Folds, Bosonization and non-triviality of the classical limit of 2D
... im (x, t) − 1 denotes the number of “folds” at the point x at time t. In the absence of folds, one can set β+ (x, t) = p1 (x, t) and β− (x, t) = q1 (x, t) which then implies that all the w±,n = 0. This is the standard bosonization in terms of the collective field theory. As emphasized in [4] and [5 ...
