U most certainly is a function of V when the entropy is held fixed; your partial derivative for a closed system should be written
[tex]\left(\frac{\partial U}{\partial V}\right)_S=P[/tex].
It doesn't bode well for your argument that all the thermo texts are wrong when you have an error in your first quantitative statement.

Thanks for pointing out this error in my first post in this thread (dec15 09).
However this error does not affect my arguments against the Legendre transform in my second post (dec21 09).
