The International Year of Light (IYL) is a brilliant initiative, but if you’re wondering how to find out more about the science and applications of light, then you’ve come to the perfect place. That’s because this free-to-read digital-only edition of Physics World magazine brings together I have to admit that it wasn’t easy for us to select 10 articles from all that Physics World has published on light over the years, but I think this collection really has something for everyone. So sit back and enjoy the issue.
