This provides an orientation, or arrow of time, and it is generally believed that all other time asymmetries, such as our sense that future and past are different, are a direct consequence of this thermodynamic arrow.”

In their study, Feng and Crooks have developed a method to accurately measure “time asymmetry” (which refers to our intuitive concept of time, that the past differs from the future, in contrast with time symmetry, where there is no distinction between past and future). They began by investigating the increase in energy dissipation, or entropy, in various arrangements.

While time blatantly moves forward in the macroscopic world, the direction of time becomes confusing on the scale of a single molecule

Only on the scale of everyday experience, our intuitive sense of time correlates to the physical phenomenon of time.

So Crooks has replaced Shui.
