Strong nodes and weak ties

Disclaimer: This is a project management post, *not* a graph theory post!

About a year or so ago, I worked on networks visualization for a while, hoping to integrate such visualizations to my edition (that will still take a while, but I am confident that it will happen someday). So far, I have not really published anything conclusive or very elaborate on that topic, but it is at the core of this paper I gave in Stuttgart, and I strike the subject in this more theoretical paper I gave in Toulouse as well (both in French). (Incidentally, there is a “networks” category on this blog, where you can follow the evolution of my readings and thoughts last winter and spring) Continue reading “Strong nodes and weak ties”

Science vs. – not science?

When I answered the questions for the paper in the Berliner Morgenpost, I had trouble explaining how and where I find the time I invest in the volunteer work for refugees. The answer I gave was not very satisfactory – luckily, the article does not reflect this lack of precision. But of course, I have been thinking a lot about the meaning and consequences of my time management of the past 3 weeks. Instead of working the usual 50 to 60 hours a week for the good of science, I am probably closer to 40, occasionally 30 (which feels like almost not working at all).

Of big meetings, drawing steps in the sand, and the bakery on Saturdays at 7:35 A.M.

I am not sure to ever be able to manage this in my whole life: having an audience of over 100 persons and let people speak up when they need. So I stayed rather by the side when the meeting with the volunteer German teachers took place today and observed the chairing, the hands raising, the questions (some loud, some hardly audible), the answer (oftentimes, the same answer was adequate for the different questions), as if it was happening behind a screen or in a parallel universe. Why the discomfort of the situation, I asked myself. I am used to talking to others, to a whole lot of others sitting in front of me. I am not completely sure why this situation was such a discomfort – probably because I was afraid not to know what the questions would really mean. What the answer should really mean. When you are in class, as a teacher, your answer always means “ask, learn, go one step further”. I have no idea what the step further has to be when it comes to our German language classes for refugees. I have no idea what the expectations of volunteers are – why are they here tonight instead of cooking dinner at home? What are they expecting from the organizers, apart from chairs and pupils in the classrooms? Continue reading “Of big meetings, drawing steps in the sand, and the bakery on Saturdays at 7:35 A.M.”
