This book offers an overview of a huge range of scientific achievements in the 20th century, specifically in the field of applied science. The majority of the essays originally appeared in papers and journals such as the Daily Worker, New Statesman and Nation, Science and Society and Nature.

Insofar as one theme runs through them, it is the application of scientific knowledge for the benefit of human society. The author is unashamed to present his perspective on some of the topics discussed in the context of his commitment to Marxism. This collection of essays, first published in 1947, thus offers an intriguing glimpse of mid-20th century attitudes towards science, and specifically to the possibilities of a scientific approach to the full spectrum of human endeavour as they were perceived in the aftermath of the Second World War, at a time when the Soviet Union and its creed still seemed ascendant.
