This website is not under construction. It is so ancient that it doesn't even serve cookies or ads. No 25-year itch for “classic” to “new” revamp here! It has been more or less like this since 1995 when I started it to offer my radiative transfer course notes - which did not change much either. Subtract What's past? from What's new? for the evolution. Its last major update was the 2021 move from Utrecht University webserving to AWS S3 for better reliability, speed and persistence of links in my publications.

Since September 2022 this website is maintained by my son, Martijn Rutten. This website will not be further updated, but will remain online for many years to come.

The same conditions apply to the photographs of Hans Nieuwenhuijzen (1936-2022) who requested me to post them.

Verantwoording: ik jatte "webstek" niet van onnavolgbare Interim Dichter des Vaderlands Simon Vinkenoog (1928-2009) maar van onnavolgbare collega-sterrenkundige Vincent Icke. However, address robrutten.nl follows Vinkenoog.
