Wein's displacement law is

E (T,ν) = = v3F (v/T)

This is from Omnes' book on QM

He doesn't explain why the total radiation is infinite. I'd like to know why.

E is increasing with $\nu$, if you integrate $\nu$ from 0 to infinity to get the full energy content (as all frequencies are allowed) you will see that the integral diverges.
