“Science on the air” is an enjoyable and extremely well researched account of the origins of science programming in north American radio. From 1923 to the mid-50s, LaFollette takes us in a journey through the life and programs of many scientists, journalists and storytellers who chosed radio as a medium for science communication. A journey who allow the reader to visit many success, but also many incomprehension and missed opportunities, mainly by scientific institutions, who often failed to understand the potential of radio as a tool for science communication. It is a fully enjoyable journey, that leave the reader with an appetite to know how the US situation relates to other wonderful experiences around the world in the same years, and how those pioneer experiences influenced today's landscape.
