Big Bang & beyond: Science for everyone

A theoretical physicist and pioneer of string theory, Brian Greene has spent decades exploring one of physics' biggest questions — can Einstein's gravity and quantum mechanics be brought together? But perhaps his most remarkable achievement is making such difficult ideas accessible to millions. Through books, television, documentaries and science festivals, he has turned the mysteries of the cosmos into stories people want to hear. We recently caught up with him in Beijing. We talked about science, AI — and perhaps the most important question of all: how do we make science matter to everyone?
