Inside Japan’s big physics | Part three: Belle II

In the final part of a new three part series, we go behind the scenes of Belle II, an experiment which could revolutionise the field of particle physics. For more than half a century, Japan has been at the forefront of ’big physics’, asking fundamental questions about the laws which govern the workings of the universe. Questions of this magnitude require cutting edge technology on a truly massive scale. Over three episodes, Nature reporter Davide Castelvecchi travels across to Japan to get a rare look insi
