Social networks are everywhere. Personally I like Facebook to keep track of old friends and add new ones. These friends are mostly of nonscientific background. Until recently I had never realized the importance of social networks in science. When you do your PhD and perhaps some postdoc projects here and there, it is hard to think about what it takes to become a successful scientist other than doing brilliant science. Although scientific skills are undoubtedly important, I believe that one of the key ingredients which can make or break a scientific career is a good network of friends.

I’m at a conference and I have noticed something that I have seen before: the top scientists are surprisingly nice. Now I wasn’t quite completely sure if this was true but at least some of my friends thought the same thing. Here’s is what happened. I’m at a conference that is a bit outside of my normal field, so I do not know most people but I certainly saw a lot of famous names of people who have published major papers in the field. I would muster my courage and just walk up to these famous people and say something pleasant to break the ice. Their reply typically is very courteous and you can see their eyes flitter to your conference badge immediately followed by a question like “where is Strathclyde?” Typically, you end up talking very pleasantly about science. In different situations I have found that top scientist tend to reply to your emails quickly, are happy to send you reprints (quickly), are happy to tell you about what they are doing.

Last week, my wife accused me of being rude. Not so much to her – although it’s quite possible that I am, she’s probably got used to it by now – but to others. This sort of happened because our son, Guus, is going to nursery school soon and we were interviewed by the head of the nursery school. She extolled the virtues of their bulletproof entrance door, which (according to her) had become a necessity since Dunblane. In case you don’t remember, “Dunblane” refers to a town in Scotland where in 1996 a mad man entered a school and shot dead several kids. Terrible obviously. However, I couldn’t help myself and started arguing that this was silly and that surely because this happened once in Britain, this was extremely unlikely to happen again, let alone at the particular nursery school that my child was about to attend. Her answer: “Belgium”. Clearly referring to another more recent occasion where a child was hurt. At this point, I decided to give up, judging that further discussion of probabilities or, say, Bayes theorem or shot noise wouldn’t really go over very well.
