Gaia Vince takes you for a mosey around his year's Summer Science Exhibition, held by London's Royal Society. Along the way, PRS Sir Adrian Smith talks of reforming A-Levels and a sorry international science collaboration situation as many european research grants are terminated amidst a Brexit withdrawal agreement stand-offs.
