Using Computers to Solve a Material Science Problem

In its full potential, the gap is an exponential so let me explain what i mean by that. The more sophisticated ad material we got to make, the more interactions between these electrons we got to be able to calculate. And that number grows expodentially. You know, pretty soon we need to have a computer with more components than ther are atoms in the universe. It so it's impractical. So what if we do? We approximate things. And when we approximate we don't get the right answer. What is interesting, an quantum is that for modelling those kinds of problems,. Instead of having an exponential meaning, the more electrons we add, you know, the number of calculations blowing up
