| Light-based technologies wowed the crowds at Lightfest in Birmingham, UK, a celebration of light in science, art, technology and culture held in conjunction with IYL 2015. Visit Physics World Showcase: Light to see a video of the event and other light-themed videos. |
The International Year of Light and Light-based Technologies (IYL 2015) will soon draw to a close, in a year that has seen thousands of events celebrating the science and applications of light in more than a 100 countries worldwide. Officially launched in January at the headquarters of the UN Educational, Scientific and Cultural Organization (UNESCO) in Paris, IYL 2015 has involved more than 100 partners from 85 countries – including the Institute of Physics, which publishes Physics World.
A range of international and national events have been held, touching on light in everything from archaeology and communications to medicine and the arts. The Light: Beyond the Bulb project, for example, has put the science of light into public settings around the world, such as parks, metro-stations, airports and libraries, while the Study after Sunset initiative promoted the use of solar-powered light-emitting-diode (LED) lanterns in parts of the world where there is little or no reliable source of light after dark. The iSPEX-EU campaign has used "citizen science" to measure air pollution with smartphones; while children, teachers, scientists and artists from more than 25 countries came together to write the "SkyLight" science opera.
