If you arrived here by chance, you deserve a word or two of explanations. This is the blog of a real-world person. Like all real world people I am sometimes Serious and sometimes Not so serious, and sometimes too I just let my mind wander and speculate on various subjects.


Serious side covers mainly climatology, global agriculture and food security

Vaguely philosophical

Issues that puzzle me for various reasons, basically dealt with Seriously

not serious articles

Not so serious

Not so serious side is mostly made of subjectivity and a fair dose of derision

eifel articles

4 – A time of moving boundaries and variable weather! (3/18/2023) Posted in: Eifel This chapter attempts to put the locations the spouses originated from in the broader historical context of “Germany” and of “Europe” between 1800 and 1935, as it is clear that most people who married between Hallschlag, Virneburg and Mehring were “Germans” who came from areas that were part of the “Germany” of the time.

3 – Locating places and sampling the database (3/2/2023) Posted in: Eifel About 2500 localities were eventually selected (sampled) and assigned coordinates. The post describes the problems, sources of the coordinates and some other issues encountered in the preparation of the final “clean” list of places used in the statistical analyses. 2.1 Finding coordinates Place names were located using a number of webtools, each with their specificities, […]
2 – The project database (2/28/2023) Posted in: Eifel This project aims at describing some features and trends affecting weddings in the Eifel, including their geography i.e. finding out, for instance, how far away from home brides would marry.

The purpose is to contribute to the statistics and geography of weddings in the region in a broader sense, and hopefully identify some generic patterns and trends.

Be my guest: save the Planet! (1/25/2023) Posted in: Vaguely philosophical Almost 13 years ago I published a post with the title Projects that will (perhaps) save the planet.

(11/15/2022) Posted in: Vaguely philosophical By Marton Bussay (MB) and Wergosum Cranes and their migrations have been around forever. They are associated in our memories with cold and short fall days, but they also bring up thoughts about freedom and the comforting side of cyclic natural phenomena: the Cranes are free birds living their free lives but they are dependable, […]
