Topic Overview

We will come to know different approaches to determine the classical equations of motion of mechanical systems, and to discuss the features of the solutions of these equations. The following topics will be covered

Mathematical Methods.     Vectors, coordinates, complex numbers, equations of motion, conservation laws
basics of variational calculus, solutions of differential equations
Newtonschian mechanics. axioms, Galileo-transformations, phase space
Lagrange mechanics. derivation, equations of motion
Model systems. motion of planets and asteoroids: Kepler problem
solid bodies: center of mass, rotation, reflection

PhyPhox, Python, and Sage

I will use PhyPhox to illustrate the relation between observations, models and theory.
Python and Sage will be used for numerical studies and visualization. The script files are notebooks that run interactively in Jupyter. Please store them on your computer, start Jupyter, and then open the notebook. The files contain absolutely minimalistic explanations and comments. I assume that you know what they are intended to do because we discussed the problems in a seminar or in class.

As introductions to Python and Sage I recommend the books Steward: "Python for Scientists" and Zimmermann u.a.: "Computational Mathematics with SageMath".

Lecture Notes

I am striving to TeΧ my lecture notes. The present state of this project is available here. Help is greatly appreciated. I offer guest access to the full project such that you get access to the files, follow tickets, open issues, and submit contributions to the project. Please register at the GitLab Server of the University, enter a comprehensible name in the settings dialog of the top right drop-down menu, and let me know that you wish to participate.



Home Work Problems

The first homework will be published here on Thursday after the lecture.
In subsequent weeks it will be ready by Wednesday such that there is the opportunity for feedback on Thursday.
