| Although his reception was on May 20th (see the image of that day), today marks the formal date of Jaap's retirement. The reception was the usual ASTRON retirement party, with a raft of eminent speakers emphasizing the salient aspects of Jaap's career and character.
But the real highlight was the ASTRON cabaret. Since Jaap is finally getting around to writing his PhD thesis, a set of images of ASTRON 'Professors' was collated into an intimidating decor. See whether you can identify them all (the one at the top right is Moore, of Moore's Law). A mock examination committee then did a remarkable job in interrogating a mock promovendus, who passed with flying colours. We trust that the real one will do as well, when the time comes.
