INTRODUCTION

A first step to theoretical physics is the mathematical description of space and time. This is based on coordinate systems consisting of an origin, basis vectors and coordinates.

We parameterize a Mexican hat by

We consider spherical coordinates \[\vec r = \left( {\begin{array}{*{20}{c}} {r\sin \theta \cos \varphi } \\ {r\sin \theta \sin \varphi } \\ {r\cos \theta } \end{array}} \right)\]

Trajectories

In contrast to water waves or sound waves, for light signals there is no medium to which the velocity of the signals can relate. There is only the observer, and nothing else. Light signals

For the formulation of classical mechanics, Isaac Newton distinguished sharply between content and dynamics. His dynamic laws apply in general, regardless of any content. They are then

Here we calculate the reflection and transmission of a plane quantum wave at a 1D Woods-Saxon potential.

Instead of coordinates of lines points, movements of the pen are specified. There are commands for forward movement, rotation, color and storage of states:
