The wonderful creatures of the Valkenburg County Cave (Updated)

The town of Valkenburg is located in gently rolling hills on the southern border of the Dutch isthmus of Limburg, bordered by Belgium to the south and west, and Germany to the east. For centuries, people have been mining the rich sandstone deposits in the area, and have thus stumbled upon numerous fossils. Perhaps none are more famous than those of Mosasaurus. The first of these was found in 1764 and now resides in the wonderful Teylers Museum in Haarlem (which also happens to be my part-time employer). The other, found around 1772, found its way to Paris through the evil machinations of the devious French (note that I’m not judging anyone).

Meeting Hydrarchos in Person(s)

As you might have guessed from the title of this blog, I have a bit of a ‘thing’ going for Albert Koch’s Hydrarchos harlani. Last week, we were lucky enough to meet up with Hydrarchos (or part of her) in person, in the basement of the Museum für Naturkunde in Berlin.

Why a historian of science needs to remain a tiger outside of the zoo

From Hans Schouwenburg’s ’emotional call to arms’ for a more activist history of science, on the Shells and Pebbles blog:

I think that we, PhD candidates in the history of science, should help our colleagues in the labs. For too long we have passively described science in action, without answering the climate scientist’s call for practical action. Even worse, as Latour observed, our critical apparatus of cultural deconstruction is now being used by the ‘worst possible fellows’ to deny global warming. We are scholars who try to describe the political, ideological and social aspects of science, but we are also humans who care about the future of our planet and humanity. Because of climate change, and because of ‘bad guys’ who refer to us to trivialize the problem, our very future is at stake! We can no longer observe these developments from a distance. It is about time to draw a firm line and come into action.

I can hardly express how much I believe we should remain passive. Or at least, if we choose to get active as concerned citizens, we should seriously doubt whether we can still function as historians.

The book behind Gustav Tornier

A bit of a panic yesterday. We’re in the middle of moving house at the moment, from a rather large apartment without a garden to a large garden with a smaller house. Unfortunately, that calls for a significant culling of our book collection or, if you will, a fortunate separation of the chaff from the corn. I had brought a few boxes of books to a nearby second-hand bookseller’s when I noticed I missed one particular volume – and one of those spine-freezing sensations set in.
