Thermodynamic systems: spot the invalid fundamental equation
Yeah! The issue is that it would require entropy less than zero.. which may be problematic for lots of other reasons. I got carried away by math and stopped thinking about the physical implications. In chatting with some of my peers, we eventually came to the conclusion that i) was okay but...- Kibble

Thermodynamic systems: spot the invalid fundamental equation
Late reply, but try checking postulate 4 on (i). When I put it into mathematica, I got a non-zero solution for S. $$u1 = \frac{v0 \theta}{R} \frac{S^2}{V} e^{\frac{S}{n R}};$$ Solve[D[u1, S] == 0, S] {{S -> 0}, {S -> -2 n R}}- Kibble

Insights Interview with a Physicist: David J. Griffiths - Comments
I may be alone in this, but I find this statement troublesome: The language he uses here, and throughout the interview, seems to reinforce the rift between the lay-person and the scientist. While it is certainly true that some physical concepts require a lot of math to fully develop, it is...- Kibble
