Light was the theme in the UK’s second city last Friday when I and my colleague James Dacey attended Lightfest at the Library of Birmingham. Organized by Aston University and funded by the European Commission, the festival was a celebration of light in science, art, technology and culture during the International Year of Light (IYL2015).
Outreach activities like these often attract a self-selecting group of people already interested in science, which is great but means that others miss out. The beauty of holding the event at Birmingham’s splendid new library was that it was enjoyed by people who might have had no idea about IYL2015 or who would never have gone out of their way to attend a science event.
That’s because the Library of Birmingham is not just about books; it’s also a great public building where people come to meet up, study, eat or just enjoy the panoramic views of the city from the sunny, roof-top terrace (complete with fragrant herb garden).
In addition to a series of public lectures, there were lots of demonstrations put on by electronic-engineering students from Aston University’s Institute of Photonic Technologies, including a “laser harp”, an LED light cube and a clever gadget that lights up when you receive an e-mail or social-media post. (I’m sure that could make a great geeky product some day.) Local astronomers were doing a spot of solar-watching from the balcony, while film-makers screened a selection of short light-related films.
The festival was officially opened by Julia King, a former chief executive of the Institute of Physics, which publishes Physics World, who has spent the last nine years as vice-chancellor of Aston University. In the photograph above, King (right) was on hand to symbolically accept Maxwell’s Torch.
Created by Mike Stoane Lighting in Edinburgh with support from the Institute, the torch marks the 150th anniversary of James Clerk Maxwell’s famous equations of electromagnetism, which show that electrical and magnetic disturbances travel at the speed of light. The torch has been touring Scotland and this was its first appearance south of the border.
