Did they manage a whole series of lectures on that? so no, missed that one.Do you remember the one they did on hair shampoo?
I have watched them on and off for years.
Have always loved science even though i am not a natural mathematician, or scientist. Even did Maths and two Sciences at A level though should really have done English, French and Music. so got got rubbish grades, though it has to be said in a better school I would have done better.
