   ... functions it can differentiate integrate take limits solve equations factor polynomials expand functions in power series solve differential equations in closed form and perform many other operations it also has a programming language that you can use to extend maxima s capabilities the dangers of computer algebra with all this marvelous capability however you must bear in mind the limitations inherent in any such tool those considering the use of computers to do mathematics particularly students must be warned that these systems are no substitute for hands on work with equations and struggling with concepts these systems...

   ... expression for lorentz force is not deduced from maxwell equations or the special theory of relativity expression for this force is usual receive from lagrange equations for dynamics of a particle in which interaction lagrangian steals up in such kind that it corresponded to experiment therefore it is possible to believe that the finding of this force generally is not very simple having a preliminary set of the equations which have been considered by us it is possible to try to estimate character of interaction between particles moving with optional velocity thus it is possible to act in two ways in the beginning to find a kind of a field of the scattered waves from the first particle in view of its movement and then to find force of influence of these waves on the second particle or on the contrary the question on how the moving particle influences on motionless has been solved at a finding of retarded potential 15 33 1 on a moving particle this retarded potential obviously will influence a little differently as it is required to define thus the picture of the scattered waves of physical vacuum which was spherically symmetric in a static is deformed twice in the beginning due to movement of the first particle into physical vacuum and then due to movement of the second particle generally electromagnetic interaction between moving particles is very complex for an estimation of character of this force we shall consider the elementary case namely an example from magnetostatics i e interaction of one moving arbitrarily electron with an electric current or a cloud slowly moving electrons for simplification of calculations we shall consider that velocity of particles is small and therefore consequently some effects of delay of fields can be neglected interaction between moving particles conclusion of the basic equations the force acting on separate motionless electron...
