Never watched it, (either of them) so don't know of her.
Very selective concerning what I watch ont telly.
I think it is mostly rubbish, so usually only watch news and film, and maybe the occasional drama.

I always thought that there was a kind of elegance in Calculus, so I guess the interest remained long after my using of it had ceased.
Have bought another calculus book since, but to get the most from it, I really need the software package called 'MAPLE'. I cannot afford it! Four figure sum for personal licence!
