> Using existing biological data, researchers at the University of Waterloo built a mathematical model that simulates how an average person's body regulates potassium, both in times of potassium depletion and during potassium intake. I guess a mathematical model of how the average body regulates potassium leaves no room for error... right? No chance of causing the problem the think they will fix? > The model could be used for a virtual patient trial, allowing researchers to generate dozens of patients and then predict which ones would have hyper- or hypokalemia based on different controls. Mathematical models, average person, virtual patients, generating dozens of patients... at some point we will get to reality, I hope! It surely does not need repeating that: the map is not the terrain.
