After World War One, new institutions and gadgets gave reality to a changing landscape of public culture. Therefore, in this chapter, we explore applied science in the inter-war public realm. Society’s usage interacted with officials’ language as public and bureaucratic discussions of applied science intertwined. Talk about applied science connected intimately with an intense discussion of ‘modern civilisation’ to make sense of science too. Amidst anxiety, the separation of pure and applied became important to science’s standing. To some, the process by which scientific research led to a multitude of new gadgets was frighteningly dangerous. To others, science was exploited too slowly due to the historical inadequacy of British industry. Both branch of government and a cathedral of applied science, the Science Museum displayed linkages between science and technical wonders. Debates were conducted over the new radio service and in newspapers, and were contested by bishops as well as politicians.

At the beginning of the twentieth century, the dominant reference of applied science changed. This chapter addresses the question: How could research be discussed using the old language of applied science previously used principally for pedagogy? Where was the continuity? The term’s meaning was constructed and reconstructed with the new organisations, such as the National Physical Laboratory and the newly incorporated civic universities. Therefore, the hectic emergence of a host of new organisations and awareness of research is of particular interest. In an era of growing foreign competition, Liberal politicians such as R. B. Haldane put their faith in applied science. Three key themes structure the analysis: the challenge of foreign powers, the growth of institutions, and the attraction of applied science to governments committed to maximising national efficiency but minimal interference in the market. The focus is on the years between 1899 and the outbreak of war.
