Of all the ideas Janna Levin presents, the most provocative and disturbing, perhaps, is her doubt that there is free will in human existence at all. She cannot be sure that we are not utterly determined by brilliant principles of physics and biology. Yet she cleaves more fiercely in the face of this belief to the reality of her love of her children and her hopes and dreams for them.
Janna Levin launches a new film about Alan Turing at the World Science Festival.
An astrophysicist who studies the shape of the universe, Janna Levin has also explored her science by writing a novel about two pivotal 20th-century mathematicians, Kurt Gödel and Alan Turing. Both men pushed at boundaries where mathematics presses on grand questions of meaning and purpose. Such questions, she says, help create the technologies that are now changing our sense of what it means to be human.
