|You have discovered enough of myself in reading my homepage. Here a few more things.|
|The picture on the left dates from the time Brigitte Bardot was the most acclaimed French actress... Algeciras, Spain. Photo taken by Bernard on our way to the Sahara.
On the right, windsurfing in Corsica, 1980.
I grow all sorts of edible and ornamental plants on the terrace.
If you want to know in what sort of trade I am active, this is a chemical technology called ion exchange. It is mainly used to purify industrial water, but has also many applications in the chemical, mining, petrochemical, pharmaceutical, and food processing industries. I have almost 40 years of experience in ion exchange that I spent advising customers in the entire world, and I offer now consultancy for projects related to industrial water treatment. I can work in four languages: French, English, German, and Spanish.
|Persistence of vision
Have you heard about Ray Tracing? No, this is not the latest Californian pop-star, it is a computer technique to create synthetic — or virtual — images. Click on the picture at the left for an example. A serious business. See 110 different pictures I created, with explanations about the whole process of ray tracing, including panoramic pictures.
I also made a special chemical page with pictures showing the structure of molecules and crystals.
Another hobby: soilless (hydroponic) culture. Principles and examples. Also in French. My version of hydroculture uses ion exchange fertilization. I have been practicing this type of culture with indoor plants for 40 years.

|I changed my good old Vespa for the latest model by Piaggio. The picture on the left with an early Vespa is from the film "Roman Holiday", by William Wyler. In the picture on the right, I am driving the Vespa of my friend Fernando in the region of Zürich, around 1965.|
|I also drive occasionnally this Citroën 11 BL Traction Avant, which I bought in 1984. The picture on the left was taken in Bagatelle, a park near Paris, in 2016, the picture on the right at the Mont Saint-Michel in 1984. Click the small images.|
