Many processes in nature are emergent, diffusion, which was discussed in the intro- duction, and electric current being prime examples. In the case of electric current, electron motion in metals is largely random and dominated by thermal fluctuations. It is, however, slightly more probable for an electron to travel in the direction opposite to the electric field than any other, but the particles travel in all directions. The drift is only noticeable due to the large number of individual particles affected and would barely be apparent to a hypothetical microscopic observer. However, the macroscopic observer has a sense of flow through the conductor, not unlike that of water in a stream, due to effects such as the magnetic field that surrounds the conductor. The electrons are not collectively flowing through the wire in the same way that gas molecules are not pressing down on one another due to gravitational effects, yet a scale is affected as if the later were true
