 === Effective diffusion coeffiient ==
 
-The effecitve diffusion coefficient is $\frac{n \chi}{\rho c_v}$
-which determines the diffusion time scale etc...
+The traditional diffusion equation looks like
+
+$\frac{\partial T}{\partial t} =  D \nabla^2 T$
+
+where $D$ is the diffusion coefficient.  For uniform density, magnetic field, and for $lambda = 0$, the equations revert to the traditional diffusion equation with 
+
+$D = \frac{n \chi}{\rho c_v}$
+
 
 === Isotropic Case ===
