Spectroscopy Mix (ft. Robert Thompson)
Light doesn't only let us see things, it can also reveal what exactly they're made of. Everything from the composition of stars, to the difference between a healthy cell and a cancerous one. Robert Thompsom 'shines a light' on the wonders of spectroscopy, as well as organic electronics (the future of tech!) and how to make your very own spectrometer with only a cereal box and a CD. Plus our weekly science news and a particularly firey Fieldwork Faux Pas.
