Professor John Ellis (CERN) gave this years Rochester lecture to a packed audience of undergraduates and academic staff. The lecture was entitled
`Gauguin’s questions in particle physics: Where are we coming from?
Where are we now? Where are we going?''
Within particle physics and cosmology Gauguin’s questions may be interpreted as: What is the status of the Standard Model? What physics may lie beyond the Standard Model? What is the ‘Theory of Everything’? What were the early stages of the Big Bang? What is the material content of the Universe today? What is the future of the Universe? In this lecture I highlight how new facilities and ideas in particle physics and cosmology can shed light on the questions raised by Gauguin.
