Paul Doherty is one of the worlds best science teacher and communicator I know, and as one of the senior scientists here he is also my adviser at the Exploratorium. Here is Paul in his element, showing off one of his fun, cool physics toys and teaching about Newtons laws on public television:

Paul was my teacher when I was at the Teacher Institute at the Exploratorium in 1997. He is great. A wonderful explainer. Here, he interchanges Newton’s second and third laws. Only the labels; his explanations are (as usual) right on.
Hi Paul!
Best regards,
Marty
