E A Milne was one of the giants of 20th century astrophysics and cosmology. His bold ideas, underpinned by his Christianity, sparked controversy OCo he believed two time scales operate in the universe.Struggling against poverty, Milne won five scholarships to Cambridge, but he never finished his degree. In World War I he was invited to develop Horace Darwin''s device for anti-aircraft gunnery and after the Armistice his prowess in ballistics took him straight to a Fellowship at Trinity College, Cambridge. By the age of thirty he was a Manchester professor and a Fellow of the Royal Society. At Oxford he battled to improve the university''s attitude towards science, and established a world-centre of astrophysics. He suffered from Parkinsonism in his forties, the consequence of his having had encephalitis lethargica as a young man. However, buoyed by his Christian faith, he did not slacken his pace. When he died, twice widowed, the author OCo Milne''s daughter OCo was a teenager.This book is born out of curiosity. The author''s aim is to show the human face of science, how the course of her father''s life was shaped by circumstance and by the influence of illustrious friends and colleagues such as Einstein, Eddington, G H Hardy, J B S Haldane, Hubble, F A Lindemann and Rutherford. Against all odds, Milne emerged as a scientific powerhouse OCo and a rebellious one at that.
