Time expert fears sundials are ‘old hat’
A self-confessed “time enthusiast” says getting young people to love sundials is an “uphill struggle”.
Dr Frank King, a Cambridge academic, is the mathematical brain behind some of the country’s most striking timepieces.
The 76-year-old, who is also chair of the British Sundial Society, calculates precise measurements which are then constructed in a workshop.
He says the number of people who “really understand” the science behind them “are few and far between”.
“Anything from atomic clocks to the most ancient of sundials I can tell you about,” he says.
As Keeper of the Clock, he is responsible for Cambridge University’s official timepiece on Great St Mary’s Church.
But it is the future of his passion that concerns him.
“Sundials are old hat,” he says. “Those few people who are making innovative sundials are making extensive use of computerised tools to design them – that’s a good thing.
“To get young people interested in sundials is extraordinarily challenging.”
How do sundials work?
A sundial uses a shadow cast by a thin rod called a gnomon on to a flat surface etched with different times.
The latitude and gradient are taken into account to decide the precise location, ideally on a south-facing wall.
Its accuracy varies according to the time of year, and the amount of sunlight in a day.
Lida Kindersley has created more than 20 of his designs in her Cambridge workshop.
“His work is alchemy,” she said. “I am totally in awe of him.
“Sundials position us in the universe, in the vast unknown.
“I know when we make a sundial it’s going to be right.”
Dr King strongly believes the sundial – “the perfect collaboration of science and art” – has a place in the digital age.
But he is concerned that the skills needed to create them may dwindle, and believes education could play a greater role.
“There seems to be no teaching of spherical triangles, and very little teaching of solid geometry.
“How many school leavers have heard of Euclid?”
