In celebration of the event, Physics World magazine has released a free-to-read digital edition containing 10 of its best features on the science and applications of light. The articles range from the physics of rainbows and the science of “smart holograms” to how butterflies are inspiring photonic technologies that exploit the power of light.

There’s also a feature by Shuji Nakamura, who shared the 2014 Nobel Prize for Physics, about how he developed efficient blue light-emitting diodes, as well as an intriguing tale about the life of Ibn-al-Haytham, the talented Egyptian scholar who revolutionized our ideas of optics 1000 years ago. Plus, you can relive the best images taken by the most famous optical instrument of all, the Hubble Space Telescope.

Read the edition on your desktop, or by downloading the Physics World app – available for iOS and Android from the App Store and Google Play – onto your tablet or smartphone.
