Brian Greene is a theoretical physicist, mathematician and writer, whose area of research is string theory. His books and broadcasts distil the complexities of science for a general audience, leading one critic to say appreciatively “he speaks maths, physics and human.”

Born in New York City, his father taught him the basics of arithmetic when he was a toddler and by the time he was five Brian was multiplying 30-digit numbers by 30-digit numbers - just for the pure joy of working things out by himself. At 11 Brian had exhausted everything his maths teacher could teach him but, thanks to his teacher’s resourcefulness, he managed to get extra tuition from a graduate student at Columbia University.

After graduating from Harvard in 1984, Brian won a Rhodes scholarship to Oxford University to study gravity and quantum mechanics. At Oxford he became captivated by the idea of string theory which was causing much excitement among the physics community at the time. String theory was seen as having the potential to answer life’s big questions about space, time and the universe.

Brian is currently professor of physics and mathematics at Columbia University.
