singularity

For a while I thought this was a case of numerical difficulties caused by the very large value of C in your equation, but now I think Maple is right: there really is a singularity here. I changed epsilon0 to 1E-3 to make things gentler (C is now 79.57747152), and Maple reports the singularity at t = .23214044. Plotting T(t) for t from 0 to 0.23 shows what looks very much like a vertical asymptote, with T(t) going to -infinity.

Thank you very much for your
