Stephen Hawking exhibition hopes to unravel the mysteries of his blackboard

Science Museum hopes fellow travellers of the late cosmologist will join visitors to display of his office miscellany

Having devoted his life to the conundrums of the cosmos, Prof Stephen Hawking has left behind a mystery of his own amid the eclectic contents of his former office.

The Cambridge cosmologist, who died in 2018 at the age of 76, treasured a blackboard that became smothered with cartoons, doodles and equations at a conference he arranged in 1980. But what all the graffiti and in-jokes mean is taking some time to unravel.
