An array of speakers lined up for their lightning talks at the Dutch Semantic Web Meetup #dswm #conference

In August 1999 a solar eclipse moved over Europe. It was complete in a small band from the tip of French Normandy to the east-north-east. All of Europe went out on that single day to get a glimpse of the totality.

The morning of June 8, 2004 the planet Venus moved in front of the sun. Since it was beautiful weather, I mounted my telescope on top of our office building in Delft and projected the image of the sun on a white sheet of paper. During the six hours of the event, we regularly paid a visit with different colleagues to take a live look.
