In the Dark

There was an article in today’s Observer in which four scientists from different disciplines talk about how in various ways they all get a bit emotional about their science. The aim appears to correct “the mistaken view that scientists are unemotional people”. It’s quite an interesting piece to read, but I do think the “mistaken view” is very much a straw man. I think most people realize that scientists are humans rather than Vulcans and that as such they have just as many and as complex emotions as other people do. In fact it seems to me that the “mistaken view” may only be as prevalent as it is because so many people keep trying to refute it.

I think anyone who has worked in scientific research will recognize elements of the stories discussed in the Observer piece. On the positive side, cracking a challenging research problem can lead to a wonderful sense of euphoria. Even much smaller technical successes lead to a kind of inner contentment which is most agreeable. On the other hand, failure can lead to frustration and even anger. I’ve certainly shouted in rage at inanimate objects, but have never actually put my first through a monitor but I’ve been close to it when my code wouldn’t do what it’s supposed to. There are times in that sort of state when working relationships get a bit strained too. I don’t think I’ve ever really exploded in front of a close collaborator of mine, but have to admit that one one memorable occasion I completely lost it during a seminar….

So, yes. Scientists are people. They can be emotional. I’ve even known some who are quite frequently also tired. But there’s nothing wrong with that not only in private life but also in their work. In fact, I think it’s vital.

It seems to me that the most important element of scientific research is the part that we understand worst, namely the imaginative part. This encompasses all sorts of amazing things, from the creation of entirely new theories, to the clever design of an experiment, to some neat way of dealing with an unforeseen systematic error. Instances of pure creativity like this are essential to scientific progress, but we understand very little about how the human brain accomplishes them. Accordingly we also find it very difficult to teach creativity to science students.

Most science education focuses on the other, complementary, aspect of research, which is the purely rational part: working out the detailed ramifications of given theoretical ideas, performing measurements, testing and refining the theories, and so on. We call this “scientific method” (although that phrase is open to many interpretations). We concentrate on that aspect because we at have some sort of conception at least of what the scientific method is and how it works in practice. It involves the brain’s rational functions, and promotes the view of a scientist as intellectually detached, analytic, and (perhaps) emotionally cold.

But what we usually call the scientific method would be useless without the creative part. I’m by no means an expert on cognitive science, but I’d be willing to bet that there’s a strong connection between the “emotional” part of the brain’s activities and the existence of this creative spark. We’re used to that idea in the context of art, and I’m sure it’s also there in science.

That brings me to something else I’ve pondered over for a while. Regular readers of this blog will know that I post about music from time to time. I know my musical tastes aren’t everyone’s cup of tea, but bear with me for a moment. Some of the music (e.g. modern Jazz)  I like isn’t exactly easy listening – its technical complexity places a considerable burden on the listener to, well, listen. I’ve had comments on my musical offerings to the effect that it’s music of the head rather than of the heart. Well, I think music isn’t an either/or in this respect. I think the best music offers both intellectual and emotional experiences. Not always in equal degree, of course, but the head and the heart aren’t mutually exclusive. If we didn’t have both we’d have neither art nor science.

In fact we wouldn’t be human.
