What's new on my WWW pages? - last change:  2 February 2025

• Waterbeelden: an exhibition in June-July 2009 of some of my photos with water -- the Dutch word "beelden" means 'images/pictures' but also 'sculptures'. The few lines of text are in Dutch only.

• I love Scotland for all the beautiful things it has to offer: nature, landscapes, buildings, etc.
  During my 1995 holiday I made a trip along Highlights of Scotland. And in the period June 1996 -- May 1998 I worked at the University of Dundee and therefore have plenty opportunities to look around in Scotland.
  Following the above link leads to a page with links to lots of pretty pictures taken in Scotland!

  See the Scotland photo index for a full list of the 110 photos I scanned for you; here is one of them:

  
  Glen Esk
  

• fresh snow on January 6, 1995 (ca. 32 kb), showing that the weather can be enjoyable in The Netherlands.

• spring of 1994 (ca. 39 kb)

I'm very fond of my pets (ca. 32 kb) and of cats (ca. 13 kb).

Here are some of the pictures I found on Internet (35 kb).
 

• Atmospheric scientist in De Bilt, June 2011 - present
  Assisting in the development of methods for monitoring the composition of the Earth's atmosphere using satellite data, notably development of the NO2 retrieval algorithm for instruments OMI and TROPOMI.

• Guest teacher at after-school care [Dutch: Gastdocent naschoolse opvang], July 2010 - Jan. 2011
  Volunteer for the project "Cool! Climate After School", which intends to introduce sustainable energy and climate change to children -- info in English  |  info in Nederlands.

• Atmospheric scientist in De Bilt, March 1999 - March 2004
  Assisting in the development of methods for monitoring the composition of the Earth's atmosphere using satellite data, notably the distribution of ozone and other trace gases, and the UV radiation reaching the surface (UV index).

• Research scientist in Dundee, June 1996 - May 1998
  A research dealing with numerically and experimentally modelling of Meddy-topography interactions, where the numerical work is again done with a Finite Difference Method.

• Research scientist in Eindhoven, Sept. 1993 - March 1996
  A research concerning numerical simulations of 2D vortex evolution with a Finite Difference Method which I developed and extended.

• Ph.D. thesis research in Utrecht, June 1988 - Jan. 1993
  A numerical investigation of some aspects of the Sun's magnetic field, leading to a thesis called Magnetic energy balance and period stability of the solar dynamo.

• Several pages where I write about Music and lyrics that interest me, with much about:

  Sarah Brightman       and       Loreena McKennitt

• About the start of the third millennium, which was at 1 January 2001 AD !
  (That page is made for a browser that understands JavaScript.)

• Chickens, or: the essence of scientific research

• A citation on the aesthetic excitement of science

• "I always knew sport was bad for your character"

• Zomaar wat recepten (Dutch only)

• Ik ben een fan van de Wonderreizen van Jules Verne (Dutch only)

===> Some statistics, namely:

number of HTML files on my Web site

 
This quote -- often incorrectly credited to Voltaire (1694-1778) -- originates from "The Friends of Voltaire" (1906) by Evelyn Beatrice Hall, summing up Voltaire's beliefs.

In my opinion this applies to any and every aspect of life, whether political, economical, social or religious. And I think that only when every individual can truthfully say these words, the world can be a better place: open, democratic and tolerant.
 
Here is another citation, that does not contradict the previous, nor is it an excuse of any form:

 
===> I am collecting translations of this in as many languages as possible

===> How to pronounce my name

 
All my Web pages satisfy the standard, they are and they satisfy the "luminosity contrast ratio" of the at level 3 -- see this page for some notes.
