Mr King took the first Spark Lecture of the term entitled The Copernican Revolution.
The lecture was about Thomas Kuhn's influential book, The Copernican Revolution which looks at the transition from the ancient Earth-centred view of our Universe to the modern 'Sun-centred' view. The book shows how this transition was actually a gradual process over many centuries and involved the work of many scientists as well as Nicolaus Copernicus.
The lecture showed pupils how a study of the movements of the Sun, Moon and stars is arguably the oldest area of human study, since it is essential for keeping track of the seasons, farming and growing food.
It also showed pupils how Copernicus was actually following a tradition of challenging the ancient Greek models of the universe, maintained for many centuries by astronomers in the Middle Eastern countries during the Middle Ages.
