My first love

No, I do not tell who she was. At the age of 14 I was grasped by the sky. My application for the membership of the 'Nederlandse Vereniging voor Weer- en Sterrenkunde', (the Dutch Association of Meteorology and Astronomy) was refused because of my age. So without telling him my father became member of the 'NVWS'.

Later on I became a member myself. I still am.

Astronomy at the University of Utrecht.

As a student in Math, Physics and Astronomy I was in 1961 lucky to have the opportunity to attent the last two years of lecturing of the late professor Marcel Minnaert. Most famous for his 'Natuurkunde van 't vrije veld', partially published as The Nature of Light and Colour in the Open Air (1954), reprinted as Light and Color in the outdoors by Springer, N.Y. 1993, 1995.

More recent activities

Not so recent, but I intent to update the site ASAP: PyNOVAS.

Updated PyNOVAS on January 24, 2006

I would like to port this software to Sage. Cyton could be the alternative for swig.
