Dreamer and thinker: the life and times of Freeman Dyson

Freeman Dyson was a maverick mathematical physicist who studied everything from quantum foundations and space travel to nuclear power and climate change. In this month’s cover feature, Hamish Johnston explores the life of the unorthodox genius, who was born 100 years ago. Also in this issue, Jack Miller describes a new technique with roots in particle physics that could transform MRI, while Michael Allen looks at the possible dangers of radionuclides from nuclear accidents and weapons testing that occur at unusually high levels inside glaciers.
