Will Self concludes his 50 kilometre circumnavigation of the Large Hadron Collider at CERN just outside Geneva - entirely on foot. Following the course of the Collider through the French and Swiss countryside, Will stops at regular intervals to descend to the tunnel below and view the experiments. As Will gets close to completing his circuit, he visits Voltaire's chateau and an abandoned CERN experiment. The excursions put Will in a pensive frame of mind as he heads towards Geneva...

Following the course of the Collider through the French and Swiss countryside, Will stops at regular intervals to descend to the tunnel below and view the experiments. Invited to 'feel the wonder' of particle physics, Will is so far baffled. Far from wondrous, he very soon finds himself wondering about his own capacity for misunderstanding - expressing concerns...

Will Self embarks on a 50 kilometre walking tour of the Large Hadron Collider at CERN just outside Geneva. Following the course of the Collider through the French and Swiss countryside, Will stops at regular intervals to descend to the tunnel and view the experiments below. He aims to complete the circuit entirely on foot. Invited to 'feel the wonder' of particle physics, Will is unconvinced. At lunch with his CERN hosts, he questions them closely on the rationale for their work. And as...
