The Advantage and Disadvantage of Peripheral Ignorance: The Gas Adsorption Controversy.

In the early history of surface chemistry, in the 1920s, the nature of gas adsorption was a pivotal subject. A theory created by Michael Polanyi in the peripheral Hungary contradicted the received view originating from the American Irving Langmuir. When working out his theory, Polanyi had not even heard of Langmuir's rival description. However, Polanyi emigrated from Hungary to Germany, the centre of his field, and tried to defend his adsorption theory in the circle of the leading experts, including Einstein and Fritz Haber. This controversy seemed vital to his survival as a scientist and as an immigrant. The aim of this article is to recapitulate this controversy, with its sad undercurrents, the role of local science, methods of argumentation, and the work of a central scientific community.
