Iron-Bike 2007

Iron-Bike 2007

I had more kilometers done this year than ever before and I expected just a short trip of about three hours. But there were over 600 participants in my group and the race went straight on from the beginning.

I gave what I had but could not avoid to be overtaken until the last meters. This race was much more exhausting than I had expected. But when you have finished you are proud of your performance independent of the rank you have.

For the next season I want to do more kilometers and try to start for the next higher class. Mountain biking is one of my favourite sports. Its a wounderful feeling to rave down a hill, sometimes a little dangerous and rushing adrenalin

Sihlseelauf 2007

Sihlseelauf 2007

This summer my neighbors and I we joined the Sihlseelauf, a run of 14.5 kilometers along the Shilsee lake. The distance was longer and there were more ups and downs than in other years because the bridge above the lake is being repaired.

We started the race almost in the first line with the consequence that a lot of other participants overtook me during the race. But the race was even so a great fun for me.

I had an average of 5 minutes per kilometer and are very proud of my performance.

This was our first holiday with both children and our first flight with them. But it ran better than expected. Flying was wounderful and an adventure for the girls.

The weather was very good, I like the greek kitchen and the sea. I hope, we can repeat the summer holidays until the childs are not longer interested in going away with their parents.

Here is a link to our all inclusive hotel LOUIS CORCYRA BEACH in Gouvia, Corfu.

Mandelbrot

Mandelbrot

A long time ago I was impressed from this bizarre images made of the mandelbrot set. And a few weeks ago I developed a screensaver which draws different details of the mandelbrot set.

Meanwhile I know a little bit more about this image and it is much more fascinating than ever before. I invested at lot of time to get this screensaver running. But now it works. It randomly selects a part of the currently painted image and zooms inside this part. The zooming goes on until the computer is not able to calculate more detailed information.

You can download the screensaver Mandelbrot and copy the file into the system directory. Then select the screensaver in the desktop property screen and make some odd settings there. You will enjoy it and be impressed of the different images of the Mandelbrot set.

Peters Map

Peters Map

If you look at the mercator map you must think that scandinavia is almost as large as india. But the real dimensions are at the contrary. India is mor than 10 times larger than scandinavia.

And you could realize that africa is a quite small continent. But in reality africa is much larger as europe. Europe could be a small part of africa.

The mercator map does not display the real size of the continents and countries. It is absolutly europe concentrated. Europe is displayed much larger than it realy is. The petersmap gives a much better image of the real world.

Triangle

Triangle

When I attended school and had some lessons about the triangle I was deeply impressed from this odd figure.

And since I tried some calculations with vector analysis my idea was to develope a screensaver which randomly draws a triangle and calculates and paints all important points, lines and circles of the triangle.

You can download the screensaver Triangle and copy the file into the system directory.

Sudoku

Sudoku

When my wife first introduced this famous game to me I immediatly was impressed and tried to find out the logic behind the game.

After a bulk of solved Sudokus I tried to develope a Jave routine which is able to do the work. My consideration was that the program should make the same decisions as a human. The solution was quite easy.

The Jave routine implements two steps. Step one is to remove all values from the possible values of a cell that are not allowed because they are alread used in another cell of the cell group. If there is a cell with only one remaining possible value, it is the cells value.

Step two is to remove all possible values from a cell that are also possible in another cell of the cell group. If there remains only one possible value in a cell, it is the cells value. Repeat both steps until the

G. W. Bush

G. W. Bush

I really hoped that the Republicans will loose these elections and was shoked when I heard the day before on television that it will not be so sure as expected. But then it went all OK for me.

The Democrats won the absolute majority in both houses and Mr. Bushs hands are bound now.
