You know what, it makes me feel better just knowing an expert has to dredge for some of that stuff.

The prof mentioned those terms without defining them clearly enough for me, and Wikipedia wasn't helpful.

I finally found a definition of Maxwell body that makes sense to me: "A liquid whose rate of deformation is the sum of a term proportional to the shearing stress acting on it and a term proportional to the rate of change of this stress. Also known as Maxwell body."

Arrhenius plot: OK, I see that it's a way of graphing the effect of temperature on the speed of chemical reactions.

Thanks for providing the impetus to dig further :)
