4x4
You have a train station with four different directions, and you can choose one of those for arrival and departure each. 42=16. For each one of those 16 possibilities there is one railway, so it is 16 railways and 8 platforms.

Radio
When you transmit electromagnetic waves, how do they look depending on the sound or information, the frequency and the kind of modulation, let it be AM (amplitude modulation) or FM (frequency modulation)? Find it out.

S-Bahn München
If you had a map of the rapid transit system of Munich with all stations in one single row, this is what it would look like, and you completely lose the feeling for which stations are near or directly next to each other and which are not.

Mirroring music
Imagine that you turn all the notes' heights of a piece of music around.

Computer science
My dad is a computer scientist. Once he asked me to write a mathematical text with LaTeX but I did not know any LaTeX commands yet. However, I am a quick learner. He showed me the most important ones and I began.

Regular dictations
In the second, third, and fourth grade of primary school we took many dictations but we learned them by heart before. The teachers called that kind of dictation “Nachschriften”, which would be postscripts in English.
I should warn you that I am very weak in Spanish, French and Italian at the moment. It will still take a while for me to properly improve. When the time has come, I will correct all mistakes in those bad translations, well, at least those I find myself.

Mushrooms and cathayas
Drawn images of the mushrooms and cathayas
I have always been interested in mushrooms and cathayas. Unfortunately, I do not like to eat mushrooms but I enjoy finding and collecting them for others.

Cattle
I like cattle so much. They are so beautiful and nice. At the border between Germany and the Netherlands there is a large meadow with cattle. I often go there and look at it.

Great advertisement about C**.

World Trade Center
With the program Povray you can construct three-dimensional objects and then look at them. You must fix the camera location and the direction where it is looking. I made the World Trade Centers with Povray primitively.

Score of most music from that webpage
WARNING: with sound
I was excited when I found out that one can create a sound on webpages with JavaScript. So I made a test page which will most certainly remind you of an audio-CD player. For the case it does not work online you can also download it.

Homepage in high school
In “Computer science” we also had to create our own homepage. However, as far as learning to work with Excel and HTML is concerned, and we did that, I would rather call it “Computer studies.” Therefore, I used a lot of JavaScript, which gets us back to the actual subject.
