The quantum physics pioneer Enrico Fermi reportedly once said that every scientist should change fields every ten years, in order to keep a fresh viewpoint. In my case, a transition from theoretical physics to photography was an obvious choice.
It's all about visualization, you see.
As a teenager, Einstein visualized running at the speed of light alongside an electromagnetic wave, and it greatly influenced his thinking about special relativity. Imagine you are waving goodbye to a friend from the platform when his train departs. If you run alongside the train at the same speed as the train to keep waving goodbye to your friend, from your point of view the train doesn't seem to move. Similarly, Einstein realized that if he ran alongside an electromagnetic wave at the speed of light, he would see a wave whose oscillations in space do not change with time. The problem was that, unlike a stationary train, such a stationary electromagnetic wave had never been observed. A possible answer to this paradox is that it is simply not possible to catch up to an electromagnetic wave travelling at the speed of light.
In my research, I extensively used computers to solve physics problems, and I had to find ways to look at the reams of data produced by the computer simulations. In the field I used to work in, quantum ordering, visualization is quite a bit of a challenge. The quantum state of two particles is a mathematical object that lives in six dimensions (three for each particle). For three particles, it's nine dimensions. A simple carbon atom has twelve electrons and a nucleus. That's three times thirteen or thirty nine dimensions. It gets really complicated, really fast. The visualization challenge is to simplify the graphical representation enough so it can be displayed on a computer screen, while keeping enough of the information to gain useful insights into the behaviour of the system.
Superconductivity, the dissipationless flow of electric current, is an example of quantum ordering in which electrons in a metal pair up into so-called Cooper states. Nearly fifty years after their discovery, I found a way to visualize the Cooper states of various kinds of superconductors, so one could see for the first time what these objects actually looked like. These graphical representations were published in the magazine Nature, which is to scientific publications what Vogue is to fashion magazines.
I could go on and on about the fundamental role that visualization plays in physics and the sciences in general. But I'm sure that by now, you understand that I not only bring to photography strong analytical, computer and problem solving skills, but also a different way of looking at the world I developed as a theoretical physicist. The relationship between photography and my scientific background is a topic I am going to explore in detail in my blog.
You may very well have noticed that for an Edinburgh based photographer, I don't really have a Scottish sounding name. There is a very simple explanation for that. I was born and raised in Lausanne, Switzerland. My path from Switzerland to Scotland was a rather convoluted one. I spent a number of years in the United States, first as an undergraduate exchange student at Carnegie Mellon University in Pittsburgh. After graduate studies at Los Alamos National Laboratory and the University of Illinois, where I got my PhD in theoretical condensed matter physics under the supervision of David Pines, I spent a couple of years as a postdoctoral research associate at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara. I then took faculty positions at the Florida State University, the University of Cambridge and the University of Edinburgh.
