The world's most complicated machine

An introduction to this album 

An explosion in the beam tunnel caused a major setback. Accelerator scientists examine what went wrong and outline how the beam gathers speed, ready for collision 

The smaller the thing you look at, the bigger the microscope you need to use. That’s why the circular Large Hadron Collider at CERN, where they discovered the Higgs boson is 27 kilometres long, and its detectors tens of metres across. But to dig deeper still into the secrets of t ...  Afficher plus

We pick up last episode's theme of particle colliders and dive into the most exciting one running today - the LHC. What is it, how does it work, and what new physics can it still reveal?

The machine that discovered the Higgs Boson 10 years ago is about to restart after a massive upgrade, to dig deeper into the heart of matter and the nature of the Universe.Roland Pease returns to CERN’s 27-kilometre Large Hadron Collider (LHC) dug deeper under the Swiss-French bo ...  Afficher plus

Scientists at the Large Hadron Collider claim the discovery of the Higgs boson particle. Alan Barr of Oxford's Physics department, UK physics coordinator for LHC's ATLAS experiment, describes what it means for science.
