The talk was delivered 7 May 1959 in the Senate House, Cambridge, and subsequently published as "The Two Cultures and the Scientific Revolution". The lecture and book expanded upon an article by Snow published in the "New Statesman" of 6 October 1956, also entitled "The Two Cultures". Published in book form, Snow's lecture was widely read and discussed on both sides of the Atlantic, leading him to write a 1963 follow-up, "The Two Cultures: And a Second Look: An Expanded Version of The Two Cultures and the Scientific Revolution".
