Cartwright was appointed, on the advice of each Hardy and Littlewood, to an assistant lectureship in mathematics in Cambridge in 1934, and he or she was appointed an element-time lecturer in arithmetic the next 12 months. In 1936 she became director of research in mathematics at Girton College, and in 1938 she began work on a brand new challenge which had a major impression on the direction of her research. The Radio Research Board of the Department of Scientific and Industrial Analysis produced a memorandum concerning certain differential equations which came out of modelling radio and radar work.

Easter Island, with its sad stone faces, becomes Bronowski’s metaphor for a world without the wheel and with out the polestar. Without these two triggers to the creativeness, more than simply astronomy is missing. The entire dream-pushed know-how that shapes our world is absent.
