Auf geht's ins Deutsche #Bienenmuseum #Weimar.
Dort werden wir heute im Rahmen des Lehrprojekts "The Taste of History" verschiedene #Honigrezepte aus dem #Mittelalter nach weitgehend originaler Zubereitungsart ausprobieren. Ich bin schon gespannt, was funktionieren wird.

Zum heutigen #Bienstag gibt es mal wieder etwas Längeres zum Lesen. Auf dem Blog ist der letzte Woche erwähnte Beitrag zu einem bienenhaltenden Apotheker des 15. Jahrhunderts online gegangen. Lest gern mal rein und lasst mir eure Gedanken dazu da!

I made a meme for the lecture I'm giving tomorrow because I'm hip with the lingo. #Histodon #EnvHist

I may have written something useful in the regard: https://press.uchicago.edu/ucp/books/book/chicago/S/bo221935080.html

Mit der Großen #Halligflut begann heute vor 200 Jahren eine der schwersten #Flutkatastrophe​n an der #Nordseeküste.
Wir erinnern daher an eine Sammelbesprechung zur historischen Naturkatastrophenforschung:

In preparing for a paper I’m giving next week (‘The #Names of the Mangel Wurzel’ if you insist on asking!) I found this amazing #picture of Carters’ Root Stand at the 1876 Smithfield #Cattle Show. Mangel Wurzels galore! Just look at the tonnages (82 and 97) produced per acre. Achieved by growing them in #Sewage, of course. #Victorian #Farming #EnvHist

Today at 16:00 CET I’ll present online my latest book Sea Level: A History at the Greenhouse book talk https://hcommons.social/@wilko/113821932025117829 #envhist #histsci

Forbes published a nice new review of my latest book: https://www.forbes.com/sites/brucedorminey/2025/01/23/new-book-offers-reality-check-on-sea-level-rise/

“In a revelatory new book, Sea Level: A History, author Wilko Graf von Hardenberg, […], deftly chronicles just how difficult it was to come up with a standard method of measuring mean sea level. In the process, Hardenberg gives us a richly detailed yet very accessible history of how over five centuries, the concept of measuring mean sea level was a painstaking process that advanced in fits and starts.”

‘Where there’s a will there’s a way. It is the want of will and belief that keeps Sewage in our rivers instead of on the land. I call it National Suicide.’

Words that could have been penned in 2025 but actually written in 1877 with considerable prescience and wisdom by John Joseph Mechi, industrialist, London alderman, and champion of Victorian high farming. Why after nearly 150 years are we still getting it so wrong?

(this *is* a research post but it may take me a decade to get around to the writing, if I do)

I'll be presenting 'Sea Level: A History' at the Greenhouse Book Talks on January 27 at 16:00 CET. Join me to discover how our main geodetic baseline was created and how reference systems serve as powerful environing tools, starting with the conceptual history of mean sea level.

BIG thanks to #ASEH for doing this series of "remote conference" talks! (I'm doing one in late February, will post later)

It's terrific to include this flexibility and accessibility in an academic conference, wish other org's would do same @academicchatter

"Beaches and ports are among the twentieth century’s most significant and polyvalent cultural geographies. The fates of these spaces sharply diverge, however, as the rise and consolidation of the leisure beach coincides with the cultural forgetting of ports."

New! My talk for the #Reformed Institute of Metropolitan Washington on Nov. 20: "Reformed Contributions to the #Ecological Movement"--great discussion afterward!
