About the Cartoons
Nick's cartoons have appeared on the web since about 1994, and in print form in quite a number of (mainly science-related) publications, including: The Annals of Improbable Research, Physics Today, Chemical Innovation, New Scientist, Skeptic (UK), Chemistry in Australia, and New Zealand Science Monthly. In addition, a cartoon calendar has been produced by the School of Science and Technology at the University of Waikato every year since 1995. Nick frequently refers to himself in the third-person.
