Pictures of GymGa

In 37 years as a teacher at the high school "Gymnasium an der Gartenstraße" I have always been one of my hobbies, photography, having introduced.

Math/Computer Sciences

The trigger was a sick student who missed several weeks of classes because of hospitalization and asked me to provide her with educational material. Since she had internet access,

My Hobbies

My oldest hobbies are dogs (as a child Collie Tramp) and photography. At primary school, I started with an Agfa Isola (photo Dirk Böhling), a simple camera for roll film sizes 6x6, which at that time was about 40 DM.

My Webprojects

Informatics Q1

The entry into the recursion starts with calculation algorithms such as n!, Fibonacci sequence, gcd and lcm and continues with recursive graphics. A prime example of recursion is the algorithm of the problem "Towers of Hanoi". However, the applet presented here has been using the knowledge of the data structure "stack" forward. At various examples such as term calculators, waiting rooms and car washs linear data structures List, Stack and Queue are demonstrated. It continues with examples of searching and sorting. Finally, tree structures are presented with various examples.

TRS 80 or computer conquer the Gymga

The beginnings of computer use in the grammar school "Gymnasium an der Gartenstraße" can not be determined unambiguously. When I came to this school in 1978, Mr. Dipl . Ing. Maser ( teacher of mathematics at the school at the time )

Open School Server

As of 2003, our school received two new computer classrooms and the infrastructure for networking in this context , I found myself confronted with two problems. The first was the establishment of a domain server.

Programming

First programming experience I gained during my studies of mathematics in Aachen in the languages Fortran and Cobol. At high school "Gymnasium an der Gartenstraße", I learned first of all Basic, because that was the programming language which was already implemented in the ROM of TRS 80 computer.
