"I was fascinated by Prof. William Carney's charismatic personality and the love of life he was radiating. His style can be best described by the following quotation from the novel Faust by Johann Wolfgang Goethe: "Dear friend, all theory is grey, and green the golden tree of life". Instead of dryly delivering the underlying truths contained in the textbooks, he kept provoking his audience with questions and emphasising the most important points illustrated by abundant audiovisual materials."
