Are there laws in economics as well as in physics? We say yes, absolutely. Just like gravitation, classical mechanics, thermodynamics, and even quantum mechanics.

Here, we state a new scientific law governing a living society: rats in a cage, or «The Law of Diving Rats.”
This example introduces Econophysics.
