Fields like physics and economics have a lot in common. If you can understand the mathematical models of physics then you have a gateway into understanding economics. However, while practitioners in the field of economics like to call their theories scientific, they are not always so scientifically sound. And in today's lesson, we see how it takes a physicist to point that out.
The theoretical physicist Lee Smolin says economists before the economic crisis were seduced by physics because it made their arguments for deregulation seem more scientific. They believed, for instance, that an equilibrium was possible. The rest is history.
