More than 1,000 people were distracted by a double-decker – as Sheffield University went out on the road for a weekend.
For the Mobile University project academics brought their research into the heart of the city on a vintage 1959 bus on loan from the South Yorkshire Transport Museum.
The double-decker was transformed into a lecture theatre for three days and brought mini lectures to Barker’s Pool, The Moor and Devonshire Green.
People from all over the city came to learn about everything from astrophysics to ornithology in a series of 20 minute slots.
More than 30 talks over the three days covered everything from spending cuts to stem cells and heart disease to honeybees.
Places filled up fast so, once the top deck was full, others listened to audio of the lectures and watched presentations in an inflatable dome next to the bus.
Joanna from Stannington said: “My 12-year-old daughter has been really fired up by this, especially the medical talks.”
Another visitor, Brian, from Gleadless, said: ”Fascinating science talks! Plenty to go away and find out more about – more please!”
The tour project was led by Professor Vanessa Toulmin, who was also the mastermind behind the Festival of the Mind in 2011 – 11 days of events taking research to the public that welcomed more than 16,000 visitors.
This time more than 50 students and 40 staff volunteered to get involved.
