Only after a while did it become apparent that he was
talking of
the English Wikipedia. Some surprised librarian asked "are you
now talking of the English Wikipedia?" His answer was something
like "yes, the Swedish is almost completely useless" (for advanced
astronomy). In the undergraduate astronomy classes he was
teaching, all literature is in English. This seemed like an
unknown planet to the Swedish librarians. And I guess that their
surprise came as an equal surprise to the astronomer.
After eight years of teaching physics at a Dutch university and active
participation in scientific activities all over the country, I am still to
see a scientific talk given in Dutch.
