In this famous work, Sir Charles P. Snow described the dangerous split that exists between our literary and scientific communities and warned that the West could lose the race in science and technology. This new edition contains the original essay together with a new essay in which Sir Charles examines the controversy his ideas have stirred and reaffirms his belief that we have entered a new age in which science, tradition, and art have no choice but to unite. Reviewing recent developments, the renowned scientist-novelist sees hope in a rising "third culture" of social historians, economists, architects, students of government and others who are devoting their energies to the main problem--"the human effects of the scientific revolution."
