On Saturday 24th March, the Cambridge Centre for Gallium Nitride joined many other scientists on the West Cambridge site in introducing our research to the general public. This year, we chose microscopy as the theme of our public lecture with Rachel Oliver and Lok Yi delivering a talk called "The atomic gramophone and other stories" which explained the limitations of light microscopy and the new opportunities offered by electron microscopy and atomic force microscopy. After the lecture, we set up a drop in workshop in the common room at the Department of Materials Science and Metallurgy, explaining LED light bulbs to visitors with the help of our interactive Android app.
