On a Beam of Light celebrates curiosity and the powerful mind of a quiet little boy called Albert. Albert watched the world in silence – speaking at all as a young child. Then one day he is given a magnetic compass, and it sparks a lifetime of exploration.

This book is a glorious introduction to Einstein’s ideas about atoms and motion, and space and time. We learn too about Einstein’s creativity and sense of fun: his habit of playing the violin while wrestling with tricky ideas, his love of cycling and of walking barefoot through town, eating ice cream. The artwork seems to echo Einstein’s thoughts and calculations, and captures his sense of wonder about the universe. Possibly my favourite illustrated non-fiction book in the world!
