![]() MATLAB itself offers powerful methods for diverse numerical problems and graphic representations. Students like it, it is play-like, and computers are their way to deal with all kind of affairs.Īs computer language we apply MATLAB’s Symbolic Math Toolbox in the Live Editor. This allows for more complicated problems, vivid graphics and a lot of animations. For exercises, we use symbolic and numeric computer software. This helps avoid long calculations which distract from the actual physics. The laws of interaction evolve from the continuity equation for the gradients of the momentum components, where the latter is the gradient of the action function.įor the derivation of physical laws, we sometimes use symbolic computer software. We get to classical mechanics by action on point particles, and to quantum mechanics by action on detectors. ![]() It is considered as fundamental invariant expression of physics. It is introduced as scalar field whose four-gradient determines the four-momentum. In the center of our considerations is the action field. Since it is assumed that the reader possesses fundamental knowledge of physics and mathematics, a more modern view of physics, mathematics and computation can be taken. We work out the essentials, we try to clarify why the laws of physics are as they are and how the details are connected. This course is intended to help review and deepen the understanding of basics in physics. ![]() MATLAB's Symbolic Toolbox and Live Editor
