Sometimes I wonder what physics will bring me in terms of hard cash. This question may play a larger role in my subconsciousness than I realized. Saturday night I dreamed that me and my fellow PhD students from the summer school I am right now were calculating how a normal wave would traverse a medium of liquid argon. We found out that this wave has a rather complicated equation of motion, in which heavy objects are not seen, but light objects are lifted. In this dream I had the plan to rob a jewellery using liquid argon. All my colleagues agreed, so we went to a nice shop and pumped it until it was filled with liquid argon. One of my colleagues bashed a hole in the ceiling by throwing the guard. A small flame of a lighter was enough to set off a wave in the liquid argon, blowing all the shiny jewellery through the hole into our van. I felt that I had brought physics and making money together in an efficient way. Waking up was a weird experience, I noticed myself checking the room for illegal jewellery. It made me think that a physicist could make a good living in crime.
