Ars Technica: Some of the hardest problems in physics are phase transitions, such as freezing water or cooling a metal until it can superconduct. When a physical system goes through a phase transition its fundamental properties change. Even if we understand the material in either state, the behavior right near the phase transition can be very complex and difficult to understand. In developing our understanding of what happens during phase transitions physicists have developed some sophisticated mathematical tricks to help them. So how does this help with drug development?
